Nano-antibacterial pipes are pipes produced by using nano-antibacterial materials, adopting nano-antibacterial technology, using nano-antibacterial special equipment and three-layer co-extrusion process, and are called nano-antibacterial pipes.

The nanometer is a very small unit of length, equal to one billionth of a meter (1×10 to the power), which is about 100,000 times thinner than a human hair.

Nanotechnology is a high-tech that directly uses atoms, atomic groups, molecules, and molecular groups that make up various elements and substances to "assemble" materials with specific functions or products with special properties within the length range of 0.1nm-100nm. After reconstructing ordinary material materials into nanoscale materials, their physical and chemical properties will undergo great changes. Nano-scale materials generally have self-cleaning functions and have good anti-scale and anti-adhesion properties.

Nano-antibacterial technology uses the unique physical and chemical properties of nanoscale materials, adds antibacterial materials (AG+ silver ions) to them, and then stabilizes them with a substance, slowly releases silver ions at a certain temperature, destroying bacteria. Cell membranes, inhibit protein functions and interfere with DNA replication, thereby effectively inhibiting the growth of various bacteria, viruses and fungi and playing a bactericidal role. In particular, it has excellent inhibitory effect on bacteria, fungi, molds, etc. common in daily living environment, and can effectively prevent harmful substances such as bacteria that are prone to causing common and frequent diseases, as well as molds that cause black spots, slimy and odors. reproduction. For ordinary PP-R pipes common on the market, after long-term use, microorganisms will adhere to and breed on the inner surface of the pipe. When the water flow in the pipe is slow or water temporarily remains, bacteria will adhere to the pipe wall and reproduce for a period of time to form a layer of bacterial membrane, which reduces the water quality. A special bacterium breeds in hot water pipes, and they quickly multiply in large numbers and can clog the pipes in severe cases. Adding nano-scale antibacterial masterbatch to the plastic on the inner wall of the pipe (only the inner wall is in contact with water) can inhibit the formation of bacterial layers on the pipe wall and ensure the cleanliness of drinking water.

To judge whether a plastic pipe (including PP-R, PE or PE-RT pipe) is truly a nano-antibacterial pipe, the main basis is the following aspects: (1) Look at the implementation standards. Whether the pipe label is marked with the JC/T939-2004 "Antibacterial Performance of Antibacterial Plastic Pipe for Construction" implementation standard;(2) Look at the test report. Is there a qualified antibacterial test report issued by an authoritative department and whether the antibacterial rate has reached 99.99%;(3) Look at the patented technology. Whether there are invention patents or authorized use patents for nano antibacterial pipes);(4) Look at the production process. Whether the pipe is produced using nano-antibacterial special equipment and three-machine co-extrusion process (the inner layer is a nano-antibacterial layer, the main body is a plastic layer, and the outer surface is a marking line).

Germany's LIBOHAIER pipeline is produced based on the introduction of German advanced technology and integrated with the national invention patent original technology of Boxinmei Pipe Industry's "Nano Antibacterial Pipe and Manufacturing Methods"(Patent No.: ZL2016 1 1266510.9).

Don't fall into the trap of fake and shoddy nano antibacterial pipes and pay for fake products.

At present, there are many PP-R tube brands on the market, and all major brands are using various TV, Internet, advertising and other methods to promote their own brands with great fanfare. It is difficult for consumers to identify which brand is good and which brand is not good? Here is a suggestion for everyone to ensure that you will only choose the right one and not choose expensive one. (1) Look at the pipe identification, including the implementation standard, manufacturer, specification and model, production date, sanitary batch, etc.;(2) Look at the testing and certification. Is there an authoritative product quality testing report? Antibacterial test report? Antibacterial pipeline invention patent? Authoritative international quality certification? Such as European SGS testing and certification;(3) Look at the quality of the pipe, including whether the appearance of the pipe is flat, whether the inner wall is smooth, whether the wall thickness is uniform, whether the wires are bright, and whether the raw materials are pure? (4) Look at the function of the pipe. In particular, is there any function to prevent pipes from secondary pollution during conveying tap water and ensure the health and safety of owners 'drinking water?

Currently, there are three-layer three-color PP-R pipes on the market, with one color for the inner layer, one color for the middle layer, and one color for the outer layer. This three-layer tricolor tube is not the same concept as the nano antibacterial PP-R tube produced by our company. Although the nano antibacterial PP-R tube is a double layer, this double layer is a special process design developed according to the needs of nano antibacterial technology. Because in order to achieve the purpose of antibacterial and antibacterial, the inner layer of the tube wall must be added with antibacterial masterbatch and produced by a three-head co-extrusion process. The carrier of the nano antibacterial material added to the inner layer also uses PP-R as the base material. Since PP-R is a polymer material, only the same material can be used. Only then can the molecular combination of the antibacterial masterbatch and the main body of the pipe be realized to avoid delamination. Just like a patient with type O blood must be transfused with type O blood, otherwise, different blood types will not dissolve. Judging from the situation introduced by the manufacturer of three-layer and three-color PP-R pipes, the main plastic layer of the PP-R pipe is divided into three layers and three-color production. The inner layer is called the antibacterial layer, the middle layer is called the anti-compression layer, and the outer layer is called the anti-ultraviolet layer. So far, no relevant national standards and specifications for the production of three-layer and three-color PP-R pipes have been found. First look at the material. If the material of each layer of PP-R pipes is the same, is it unnecessary to make multiple layers and artificially increase costs? If the material of each layer of a multi-layer PP-R pipe is different, how to bond each layer? Will there be stratification and water leakage? Secondly, look at resistance to pressure. National standards have clear regulations on the average outer diameter and wall thickness of PP-R pipes. The thickness of the wall will not work, and the thickness will not be qualified. The PP-R material itself does not distinguish between hot and cold water. The standard for distinguishing cold water pipes from hot water pipes is based on the wall thickness of the pipes. For example, the wall thickness of dn25 hot water pipes must be at least 3.5mm, while the wall thickness of cold water pipes is only less than 2.8mm. The pressure bearing capacity of the pipe is also achieved by the wall thickness. The thicker the wall thickness of the pipe, the higher the pressure bearing. For example: dn25PP-R pipe, a 3.5mm wall thickness bearing a pressure of 2.0Mpa (20 kg), and a 4.2mm wall thickness bearing a pressure of 2.5Mpa (25 kg). How can it become that only the middle layer is the compression-resistant layer, and the inner and outer layers are not? The third is whether PP-R can protect against ultraviolet rays. National standards clearly stipulate that PP-R pipes cannot be installed directly outdoors, let alone exposed to the sun, because plastic pipes will age quickly after being exposed to ultraviolet light, and over time, pipes will burst and rupture. To sum up, the three-layer and three-color PP-R tubes appearing on the market are not as magical as they advertise. Their real purpose is to create a gimmick to fool the people and collect IQ taxes. The most important thing is to prevent these manufacturers from using the three-layer and three-color production process to fake and cut corners. The inner and outer layers use PP-R raw materials, and recycled materials or inferior materials in the middle, so as to reduce costs and make greater profits.

PP-R tube is also called random copolymer polypropylene, which is what we often call Type III polypropylene. It is obtained by random copolymerization of propylene monomer and a small amount of ethylene monomer under the influence of heat, pressure and catalyst. Ethylene monomer is randomly distributed into the long propylene chain, with ethylene monomer generally controlled between 3-5%. The ethylene content and the polymerization method of ethylene and propylene determine its cold brittleness. In the case of low temperatures, especially during winter construction, the flexibility of pipes is reduced and the rigidity is enhanced at low temperatures, showing brittleness. Under the impact of external force or excessive accidental load, direct cracking of the pipe may occur, which will cause inconvenience to construction. To this end, relevant national regulations have made clear requirements on this issue. During winter construction, attention should be paid to the low-temperature brittleness of building water supply PP-R pipes, and corresponding construction plans should be formulated. The national standard GB/T50349-2005 has detailed provisions on this. So in actual construction, how to pay attention to and prevent low-temperature brittleness of PP-R pipes? (1) During the handling process of PP-R pipes, it is strictly prohibited to throw, drop, roll, or drag;(2) The pipes are required to be stored in warehouses and simple sheds, and the stacking height must not exceed 1.5 meters;(3) During the construction process, it must be protected to avoid mechanical damage to the pipes caused by inappropriate external forces such as vehicle pressure and foot pressure. The location of the pipeline should be marked after the pipeline is secretly laid to avoid secondary decoration damaging the pipeline. (4) PP-R pipes have a certain low-temperature brittleness at low temperatures. Be careful in winter construction, and use a sharp knife to cut slowly when cutting pipes. The installed pipes shall not be heavily pressed or knocked, and if necessary, the parts that are susceptible to external forces shall be covered with protective objects;(5) Before pipe cutting, if pipes that have caused stress whitening due to external forces are found, the pipes shall not be used. (6) Before hot melt connection of pipes, carefully check whether the pipes have been damaged, especially the inner wall, because when the pipes are subjected to external force, the inner wall breaks first and then goes outside. Avoid using pipes whose inner wall has been broken but the outer tube has not been broken;(7) After installation of the pipes, the pressure must be tested before direct burial and non-direct burial. The next step can be carried out only after the pressure test is passed.

First of all, we must understand the pipe layout method of PP-R water supply pipes for home decoration. Home decoration PP-R water supply pipes are generally arranged in series connection, and the water diversion is connected to each water terminal through a household inlet main pipe and related accessories. If the specifications of the main pipe are too small, the amount of water diverted to each water terminal will definitely not be enough. Therefore, the entry supervisor must choose a larger size. For example, if there are DN25 pipes indoors, the household entrance supervisor must choose DN32 and above pipes. Secondly, we must understand the general specifications and standards for water terminals. At present, standard parts such as faucets, showers, and angle valves used in homes are all ½ wire, which means that they are the same size as plastic pipes with an outer diameter of DN20. If the indoor water pipes are also DN20 pipes, then because there is no pressure difference between the water flowing out of faucets, showers, and angle valves, there will be small water pressure, slow water flow, and small flow, and the owner will have a very poor sense of feeling. Only by upgrading the indoor water pipes to dn25 and above can a pressure difference be formed with the outlets of faucets, showers, and angle valves. The owners will have a good body feeling due to the large amount of water and the rapid flow of water during the process of washing their faces, washing their hands, and showering. It can be seen that in general, for home decoration, it is advisable to use pipes with specifications of dn32 and above for household entrance pipes, and it is more scientific to use dn25 pipes for indoor water pipes. It is not recommended to use DN20 size pipes as water pipes.

The welding temperature of PP-R pipes is generally set at 260±10℃. The specific hot melt welding procedures are operated according to the welding process parameters specified in national standards, and appropriate adjustments are made according to changes in weather and environmental temperature if necessary. The following points should be paid attention to in actual hot melt operations: (1) The connection method of PP-R pipes and fittings generally adopts hot melt or electrofusion connection. During connection, the pipes and fittings are heated to critical melting at the same time, and then the pipes are immediately inserted straight into the pipe fitting, and the welded pipes have good contact performance and a high success rate;(2) Strong winds in the workplace will have an impact on the quality of welding, because it will cool the heating plate, resulting in uneven temperature distribution;(3) When inserting the socket end vertically into the socket end, the external force should be used evenly. No hanging socket or shaking socket is allowed, otherwise the melted plastic will overflow, affecting the service life and strength of the joint;(4) Pay attention to the difference in melt flow rates between pipes and fittings should not be too large, otherwise the optimal connection strength cannot be obtained.

Under theoretical design and ideal conditions, the service life of PP-R pipes can reach 50 years, but whether it can be achieved in actual use depends on many key factors. We can understand it from the following aspects: 1. Theoretical basis and standards: The "50-year" term for PP-R (random copolymer polypropylene) pipes stems from the internationally accepted "long-term hydrostatic strength" test standard (such as ISO 9080). After manufacturers produce new products, they will calculate the theoretical service life curve under normal temperature (such as 20℃) working pressure through accelerated aging experiments at high temperatures (such as 70℃, 80℃ or even 95℃) and high pressures. Under ideal conditions (for example: water temperature of 20 ° C and working pressure of 0.8MPa), PP-R pipes of qualified quality can theoretically be safely used for more than 50 years. The "50 years" here is a statistical concept, which means that under these conditions, the probability of damage to the pipes is extremely low, and not every pipe will be able to last for 50 years. 2. Key factors affecting the actual life of PP-R tubes (practical challenges). The theory is beautiful, but the real environment is much more complex. The following factors will significantly shorten the actual life of PPR pipes: ① Working temperature: This is the biggest factor. PP-R pipes are plastic pipes and are afraid of high temperatures. Its life decreases exponentially with increasing temperature.② Used for cold water (below 20℃ all year round): The longest life, most likely to be close to 50 years.③ Used for domestic hot water (55-70℃ all year round): the life will be greatly shortened. At a high temperature of 70 ° C, its life may be only about 10-25 years.④ Special note: If some high-temperature systems (exceeding 70℃) used for central heating, the PP-R pipes will age rapidly and problems can easily occur.③ Working pressure: The higher the system pressure, the greater the long-term stress on the pipe, and the life will be shortened accordingly. The normal water pressure of the household (0.3-0.6MPa) has little effect, but if there is frequent "water hammer" phenomenon (violent fluctuations in water pressure caused by sudden opening and closing of the valve), it will seriously impact the pipeline and cause damage.④ Light (ultraviolet light): PP-R raw materials are afraid of ultraviolet light. If the exposed pipe is exposed to direct sunlight for a long time, it will oxidize and become brittle, and the strength will drop sharply, ensuring complete concealed installation.④ Installation quality: "Three points of material, seven points of installation" is vividly reflected in the PP-R pipeline. Hot melt technology: Insufficient temperature (false welding) or too high temperature (over-melting and clogging) will cause the weld to become the weakest link, and the risk of water leakage in the future is extremely high. Product quality: There are a large number of inferior PP-R pipes on the market, which are produced using recycled materials. This kind of pipe is dark and uneven in color, has many impurities, low strength, and has extremely poor heat and pressure resistance. It may burst and leak after a few years, and it cannot be said to be 50 years.

The inner layer of PEF insulation pipe is PP-R water supply pipe or PE-RT water supply pipe, and the outer layer is PEF insulation material. PEF insulation material is made of insulating polyethylene (PEF) as the main material and is made through process foaming and embossing shrinkage. Ultra-thin insulation material. Adding PEF insulation material to the outer layer of hot water PP-R pipes or PE-RT pipes has the following advantages: (1) Insulation. Good insulation performance. High-tech insulation materials can effectively slow down the heat attenuation of the medium in the pipeline and preserve the calorific value. The calorific value attenuation rate is one-tenth of that of ordinary water pipes, thereby reducing users 'heating energy consumption, saving water and electricity, and low-carbon and environmentally friendly. (2) Thermal insulation. PEF insulation materials can effectively block the heat conduction and exchange of different temperature difference media inside and outside the pipeline. The interaction between the calorific value of the pipeline and the environment is small, and the insulation efficiency is more than ten times that of ordinary water pipes. The construction of buried hot water pipes will not produce instantaneous negative heat conduction effects on the floor, cement, etc. covering the pipes, thereby effectively protecting the safety of the floor and wall. Prevent hollowing. (3) Prevent condensation water. When the room is hot and the humidity is high, and cold water flows in the plastic pipe, the temperature of the outer surface of the pipe will be lower than the dew point temperature of the surrounding air. At this time, the water vapor in the air will condense on the surface when it encounters the cold pipe wall. Into small water droplets, forming a "sweating" phenomenon. Especially in the case of returning to Nantian, a large amount of condensed water or small water droplets are more likely to appear on the outer wall of the pipe. After applying PEF insulation material to the outer wall of the pipe, problems such as "sweating" on the outer wall of the pipe and "water droplets" appearing in the south can be effectively eliminated. (4) Freezing. PP-R is most afraid of low temperatures. In winter, pipes below 5℃ will produce low-temperature brittleness. Especially in the northern region, freezing and breaking of pipes are more likely to occur during winter construction. After installing PEF insulation pipes on the outer layer of the pipe, it can play a good protective role and greatly reduce the chance of freezing and cracking of the pipe. (5) Ultra-thin. PEF insulation material is an ultra-thin insulation material produced by high-pressure shrinkage embossing. After being compounded with bare pipes to produce insulation pipes, the outer diameter of the pipes is only increased by one specification. It can be buried in walls, ground, and exposed.

The so-called equipotential means connecting the enclosures of equipment, electrical appliances, etc. or various metal appliances in the room with the ground wire to form their respective equipotential bodies to protect the safety of people and equipment. In home decoration, toilets carry more and more functions. Various electrical appliances enter the toilet, bringing hidden dangers to electricity consumption. When the human body takes a bath, the human body's impedance will be reduced, and there are also various electrical appliances in the bathroom. The 2011 edition of the National "Residential Design Code" attaches great importance to the electrical design of toilets, and clearly stipulates that residential toilets must be equipped with equipotential. The "combined self-balancing equipotential row elbow" developed and produced by Boxinmei Pipe Industry mainly has the following advantages: (1) it is detachable and adjustable;(2) it comes with a level to achieve self-balancing;(3) The ground wire interface adopts an external design and is directly connected to the ground wire box, which can be connected to both 4 square wires and 2.5 square wires without changing the metal connection structure of the wire;(4) It is produced using European standard CW617 copper wire parts, which has reliable quality assurance.

Water hammer is also called water hammer. It refers to the phenomenon that the flow rate suddenly changes and the pressure fluctuates significantly during the transportation of water or other liquids due to sudden opening and closing of the valve, sudden start and stop of the water pump, etc. In layman's terms, it means a sudden power outage or a valve closes too quickly. Due to the inertia of the pressurized water flow, a water flow shock wave is generated, just like a hammer. This phenomenon is called water hammer in the industry. The inner wall of the water supply pipeline is smooth, and the subsequent water flow will quickly reach its maximum under the "accomplice" of inertia, which can easily cause damage (such as damaging valves and pumps, etc.). This is the "water hammer effect" in hydraulics, also called positive water hammer; on the contrary, if the valve or pump is suddenly opened, it will also produce a water hammer effect, called negative water hammer. This large fluctuating pressure shock wave can easily lead to pipeline rupture or equipment damage due to local overpressure. Therefore, protection against water hammer effect is a key factor that must be considered in the design and construction of water supply pipeline projects. What are the hazards of water hammer effect? The pressure increase caused by water hammer can reach several times or even dozens of times the normal working pressure of the pipeline. This large-scale pressure fluctuation mainly causes harm to the pipeline system: (1) causing strong vibration of the pipeline and disconnection of the pipeline joints;(2) damaging the valve. Severe excessive pressure causes the pipeline to burst and reduce the pressure of the water supply network.(3) On the contrary, too low pressure will lead to the collapse of the pipe and damage the valve and fixing parts;(4) The water pump reverses, damaging the equipment or pipes in the pump room, seriously causing the pump room to be submerged, causing major accidents such as personal injury and death, and affecting production and life. Simply put: Water hammer is when water in a pipe is suddenly stopped or changed in flow direction. Pressure shock waves are generated due to inertia, which makes a knocking sound in the pipe and may also damage the pipe or equipment. Simply put, it is like driving a car to brake hard, people and objects on the car will rush forward, and the same will be true for water. If a sudden stop, it will "hit" a high-pressure wave and run back and forth. This is water hammer.

PP-R pipe fittings with right angles, such as 90° elbows, regular tees, reducing tees and other pipe fittings, are more likely to cause increased water resistance and increase the occurrence of water hammer under certain conditions than gently bent or streamlined pipe fittings. 1. Right-angle pipe fittings will definitely significantly increase local water resistance. Right-angle pipe fittings will cause sudden changes in the direction of water flow, forming vortex and turbulence, and the local resistance coefficient is much larger than that of gentle bends (45° elbows, large curvature elbows). As a result, resistance along the way increases, the pipeline system requires more pressure to maintain the same flow rate, and energy consumption increases. This can significantly affect transportation efficiency in long-distance or high-flow systems. 2. Right-angle pipe fittings do not inevitably cause water hammer, but when the inducement of water hammer exists, it will amplify the harm. Water hammer is a pressure wave caused by sudden changes in flow rate (rapid closing of valves, pump start and stop). The right-angle pipe itself does not directly "generate" water hammer, but it will intensify the intensity and reflection of pressure fluctuations because: (1) the local resistance is large → the pressure loss is concentrated → the pressure wave reflection is more complex. (2) The flow pattern is turbulent → the high-speed water flow impacts at the corners, causing the pressure to change violently. (3) Therefore, in the case of a sudden change in the flow rate, right-angle pipe fittings will make the water hammer effect more obvious and even damage the pipe. 3. How to eliminate the harm of right-angle pipe fittings in practical applications? The first is to use curved elbows, diversion tees, bridge elbows, large flow U-shaped tees, large flow inclined four-way and other pipe fittings to reduce resistance and water hammer risks; the second is to use one-tube to-bottom nano antibacterial PE-RT piping system, completely eliminate the use of right-angle pipe fittings.

Flow rate, flow pressure, and flow rate are three key indicators that describe the movement of fluids (such as water) in pipes. They are differentiated in one sentence: 1. Flow rate: How far does water go per unit of time, such as meters/second, which means "How fast is running?" 2. Flow pressure: The pressure of water in the pipeline, such as Pascal or kilogram force, means "how hard it is pushed". 3. Flow rate: The amount of water flowing through a certain section per unit of time, such as cubic meters per hour or liters per second, which means "how much has been run in total". 4. The relationship between the three: flow rate × cross-sectional area of the pipe = volume flow rate; flow pressure affects the flow rate, and the general flow rate will also change when the pressure is high.

Nano-antibacterial PE-RT water supply pipe is a new generation of functional high-tech water supply pipes developed and produced by our company based on PE-RT pipes by adding nano-antibacterial technology. It has the following characteristics: (1) Nano antibacterial. Silver ion ( Ag+) nano antibacterial, one-time installation, lifelong antibacterial. Thoroughly solve the secondary pollution of water quality generated during pipeline water transmission;(2) Energy conservation and emission reduction. The outer layer of the hot water pipe is made of embossed PEF ultra-thin insulation material, and the heat attenuation rate is 1/10 of that of ordinary plastic pipes, reducing waste, saving water and electricity. Anti-condensation and anti-freezing;(3) Excellent performance. High temperature (95℃), high pressure, low temperature (-70℃), corrosion resistance;(4) worry and effort. One pipe to the end, no joints or pipe fittings in the middle, reducing human operation and preventing hidden dangers of water leakage. (5) Safe and reliable. The pipe has good flexibility, can be bent and straightened, and has good impact resistance. (6) Easy installation. Construction and installation saves time, labor and costs, and saves more than 1/3 of the man-hours compared with traditional PP-R pipe installation. Compared with traditional PP-R water supply pipes, nano antibacterial PE-RT water supply pipes have the following advantages: (1) It has better weather resistance. PP-R pipes are only resistant to high temperatures and not low temperatures. Low-temperature brittleness will appear below 5℃. PE-RT pipes are resistant to both high temperatures and low temperatures, up to-70℃, and can be normally constructed and installed above-40℃;(2) They are more flexible. The PP-R pipe is more rigid but not flexible. It can only be straight and cannot be bent. The PE-RT tube can be either straight or bent. It can be bent at 360° or 720°, and water can be passed without direct connection, elbow, bridge bend, etc.; (3) The water flow is greater. A large number of PP-R pipes are connected by right-angle pipe fittings such as 90° elbows, regular tees, and reducing tees. The inner diameter of the joints becomes smaller, the water resistance increases, the flow rate slows down, and there is a water hammer effect. The PE-RT pipe is installed in one tube to the end, with no joint in the middle, no water hammer, no water resistance, fast flow rate, high flow pressure, and large flow rate. The pipe flow rate is more than twice faster than that of the PP-R pipe;(4) Smaller in size. PP-R pipes are produced in strips, each 3 or 4 meters long, large in size, and can only be transported and distributed by trucks. The production of PE-RT tube and coil is packed by rolls, each roll is 30 or 50 meters. It is small in size, short in length, and easy to handle, which not only saves transportation costs, but also facilitates distribution and handling;(5) It is faster to install. There are many PP-R pipe joints and many pipe fittings are needed, which is labor-intensive and time-consuming. PE-RT pipes are constructed and installed in one pipe to the bottom, reducing joints by more than 70%, saving installation time by more than 1/3, and improving construction efficiency by more than 50%;(6) saving costs. There are many PP-R pipe joints, long construction time, and large water leakage hazards. The PE-RT pipes are connected in one tube to the end, with no joint in the middle, saving materials, labor, time and worry. At the same time, they also completely solve the safety hazard of water leakage. The owner has a sense of experience and the company has a sense of gain.

One pipe to the end refers to the laying method in which the pipes from the outlet of the water separator (piece) to the water appliance are connected one-to-one with no interface in the middle.

Series connection is a single-way control system in which cold water pipes, hot water pipes, and return pipes are all connected in series, and water is diverted on the pipeline to each water point through a water diversion tee.

The parallel connection is a multi-way control system in which the water supply pipe is first connected to the water separator, and then water is supplied to each water point through the water separator, and each water point is independently controlled.

Prefabricated modules are prefabricated piping components composed of water inlet pipeline modules, ceiling water diversion modules, end water use modules, return water circulation modules, etc.

Full-floor prefabrication is a construction method in which all pipe modules are prefabricated in the factory according to the design drawings and assembled on site.

The construction method of prefabricated and combined ceiling modules in the factory into a "ceiling end module".

Nano-antibacterial PVC-U drainage pipe is a new generation of functional high-tech drainage pipes produced by adding nano-silver ion (AG+) antibacterial materials to the inner wall of PVC-U drainage pipes and using nano-antibacterial technology and double-layer co-extrusion process. Drainage pipes and pipe fittings are an important carrier for production and domestic drainage and sewage discharge. They are also the places where bacteria are most likely to breed, which directly affects indoor air quality, and is related to the physical and mental health of owners. In order to completely solve the drainage and sewage problems of toilets and kitchens, Boxinmei Pipe Industry started by solving the functions of drainage pipes and pipe fittings, organized technical research and development, increased equipment investment, and developed and produced the first nano-antibacterial PVC-U production line in China. It is the first in China to produce and promote nano-antibacterial PVC-U drainage pipes into homes and households. From the practical application situation, the tube has the following advantages: 1. The inner wall is smooth, clean and self-cleaning, never scales, and has good anti-adhesion properties. Nano-silver ions (AG+) are added to the inner layer of PVC-U pipes and are produced by using double-layer co-extrusion technology. The outer layer is a PVC-U material layer, and the inner layer is a nano antibacterial layer. The nano antibacterial material itself is smooth, hygienic, self-cleaning, and non-fouling. The dirt is not easy to precipitate, and the anti-adhesion performance is excellent. 2. Antibacterial and antibacterial, which can effectively prevent the growth and reproduction of bacteria on the inner wall of drainage pipes. The drainage pipe mainly discharges domestic sewage and fecal dirt. It is easy for bacteria to grow in the pipe wall. With the growth of bacteria in the pipe wall, it becomes pigmented and purple-black, and the inner surface is uneven and uneven, thus destroying the drainage function of the inner wall of the drainage pipe and reducing the drainage flow rate and drainage effect. After adding nano-silver ions (AG+) to the inner layer of the pipe wall, it can have antibacterial and antibacterial effects, prevent the growth and reproduction of bacteria in the inner layer of the pipe wall, prevent fouling on the pipe wall, and keep the inner wall surface of the drainage pipe always smooth, thereby accelerating the drainage flow rate and improving the drainage effect. 3. Purifying the air can effectively prevent bacteria and toxic gases from the drainage pipe network from flowing back into the room and damaging the physical and mental health of the owners. The indoor drainage pipe network and the municipal drainage pipe network are interconnected. At present, the main barrier to solve or prevent odors, odors, toxic gases and insects such as snakes, insects, cockroaches, and mice in the municipal drainage pipe network from flowing back into the room is the trap. The trap can only prevent the odors and odors from the pipe network outside the trap from entering, and can do nothing to the pipe network within the trap. If the pipe networks before and after the trap are made of PVC-U drainage pipes added with nano antibacterial materials, This can ensure that the front and rear ends of the trap are clean and dirt-free, and completely prevent bacteria and harmful gases from the pipe network from flowing back into the room, damaging the indoor air environment and affecting the physical and mental health of the owners. 4. Energy conservation and emission reduction can minimize the use of flushing water in drainage pipe networks, reduce water consumption and waste, and save water costs. At present, most places in my country still use tap water for flushing, and tap water resources are both valuable and costly. If a PVC-U drain pipe with nano antibacterial materials added on the inner wall is used, the inner wall is smooth and smooth, and it is self-cleaning and descaling, it can achieve less water and meet the flushing needs. It can also reduce water costs, save energy and reduce emissions, and achieve more at one stroke.

The design of indoor drainage systems involves drainage tools, drainage scenarios, drainage concepts, drainage technologies, etc. To test whether the drainage system decorated by a building or a house is mature, scientific, healthy and efficient, there are four main indicators: First, Drain quickly. The drainage speed must be fast, the faster the better; second, the drainage must be clean. The drainage should be as clean as possible, and the more thorough the drainage, the better; third, only out but not in. Sewage should not flow backwards in the drainage system; fourth, indoor air should not be polluted. There should be no return of odors from the drainage system, let alone any snakes, mice and insects entering the room through the drainage pipe network. The prefabricated transparent central integrated drainage system developed and produced by Boxinmei Pipe Industry is comprehensively optimized and improved based on the introduction of Japanese central integrated drainage system technology and in accordance with the principles of assembly, transparency, standardization, integration and scientificity. After years of practical testing and improvement, a world-leading "Assembled Transparent Central Integrated Drainage System" was finally formed. Specific manifestations are as follows: 1. Integrated indoor drainage. Adopt new water collection assembly drainage and sewage discharge technology, add vertical inspection ports in toilets, and install loose joints in front of horizontal pipes and vertical pipes in villas and multi-storey houses, which is more than three times higher than traditional pipes, effectively preventing and completely solving the problem of sewer blockage; 2. Pipeline construction and assembly. 3X or 4X water collection assembly, equipped with one bathroom, standard packaging, on-site positioning, and assembly construction. horizontal pipe riser bend Install a transparent double tooth joint in front of the head. Even if a blockage occurs, the tube will not be sawed or replaced, which saves money and time and is convenient for maintenance; 3. Visualize the drainage process. New transparent pipe fittings are used for all joints of the drainage system and elbows, traps and other parts that are prone to clogging. The inside and outside are transparent and clearly visible. If there is a clogging point, it will be clear at a glance and handle it accurately to eliminate potential safety hazards of clogging as soon as possible; 4. Self-cleaning and descaling are normalized. Special transparent drainage pipe fittings such as T-shaped eccentric heads and vertical inspection ports have smooth inner walls, dirt is not easy to sink, good anti-adhesion, small drainage resistance and fast speed. At the same time, the sewer can be cleaned regularly and irregularly through the vertical inspection port; 5. Maximize deodorization and anti-virus. By innovating the new "adjustable trap" extreme water storage technology, the trap can store more and deeper water, and the closure time will be longer. It has a better blocking effect on odors and harmful gases in the main drainage pipe network, and the indoor air will be clearer. Fresh and environmentally friendly; 6. Active drainage standardization. The multi-functional metal pipe code can independently adjust and fix the slope of the drainage system to ensure that the difference between internal and external slopes reaches the drainage requirements of the same layer. If it is above, it will achieve high inside and low outside, actively drain, and completely eliminate the phenomenon of insufficient drainage gradient or even backflow caused by brick supports, mounds, etc.;

The main purpose of developing and promoting colored transparent wire pipes is to make concealed projects no longer concealed. Sunshine operations and transparent construction will provide the owners with peace of mind and decoration companies with peace of mind. The "Boxinmei" brand color transparent wire tube mainly has the following characteristics: (1) The advantages are superimposed and the functions are powerful. It integrates metal tube (strong impact resistance and durability), plastic tube (flexible core, bendable), PVC tube (insulation and flame retardant), colored tube (three-line color separation), transparent tube (perspective, openness) and other wire tubes. Coupled with pure raw materials and lead-free environmental protection, it is the most advanced electrical casing on the domestic and foreign markets;(2) It is durable and reliable in quality. It will not be smashed, broken, crushed, and damaged, will not turn white after disassembly, and has strong impact resistance;(3) Socket connection, live wire wiring. All pipe fittings are connected by socket and socket, and turn in an arc. The wires in the pipe can move freely, and the wires can be changed freely between the bottom boxes;(4) Sunshine operation, transparent construction. The wire casings are transparent and visible throughout the entire process, and problems such as inferior wires, joint wires, broken skin wires, and rolled wires can be seen in a clear view. Solve them early to eliminate potential safety hazards in electricity use;(5) Three-color wiring is divided and functional zoning is performed. There are three colors: red, blue and green. The red tube corresponds to strong electricity electromechanical wires such as air conditioners and sockets, the blue tube corresponds to strong electricity lighting wires, and the green tube corresponds to weak electricity wires such as telephone and TV network signals;(6) Green and environmentally friendly, insulating and flame retardant. The material is free of heavy metals such as lead, protecting the physical and mental health of construction workers and users. At the same time, it has excellent insulation and flame retardant properties, cannot hit an open fire, and self-extinguish when it leaves the fire, poor heat transfer performance, and is safe and reliable.

"Boxinmei" brand "Bridge Hole Force Precision Flame Reaming PVC Reaming Electrical Casing" is a new generation of high-tech patented technical electrical casings that uses the design of bridge hole force and its physical principles to improve the compression resistance, drop resistance, explosion resistance, slip resistance and flame retardant properties of electrical casings, and enhance the stability, safety and durability of electrical casings. Based on the introduction of German Seiko corrugated technology and combined with the actual needs of high-end and high-quality decoration of large and medium-sized units, we develop and produce a new generation of high-tech patented technology electrical casings. It has the following characteristics: 1. Improved compression resistance. The inner wall of the pipe is smooth, and the outer wall circumference is composed of 46 conical cylinders with a depth of 0.2mm and the same height as the length of the pipe are arranged equidistantly. They are shaped like a bridge beam and column and support the outer wall of the pipe. They have stronger compression resistance, drop resistance and explosion resistance than traditional electrical casings, and the pressure bearing capacity per unit area is more than double that of traditional flat electrical casings; 2. Stick tightly. Traditional flat electrical casing is not tightly combined with cement slurry powder, resulting in two skins and even affecting the hollow drum of ceramic tiles. The shape of the electrical casing in the bridge hole is composed of 46 conical cylinders, which are combined and bonded with cement slurry powder to form a self-contained body. The integration is more complete, the connection is closer, it cannot be pulled out, it does not fall off, and it is more stable;3. It is safe and durable. Due to its special bridge hole force principle design and process structure, it can cope with various complex environments and accidental emergencies such as material pressure, human stepping, and hammer smashing on the construction site. It cannot be trampled flat, smashed, exploded, and bent continuously., it cannot be crushed, which is safe and durable;4. Lead-free and environmentally friendly. The raw materials are pure, the materials are environmentally friendly, and do not contain harmful substances such as heavy metals, effectively protecting the physical and mental health of owners and construction workers. 5. Insulation and flame retardant. It has excellent insulation and flame retardant properties, and cannot be touched by open fire Self-retaining, safe and reliable;6. Beautiful appearance. Functional zoning is adopted and three-color lines are divided. Red is electromechanical, blue is lighting, and green is weak current. In addition, the outer wall of the line pipe is distributed in a strip structure, with a cone shape and a three-dimensional cross-section. Under the illumination of the light, it is dazzling and shining.
