The difference between pvc pipe and aluminum-plastic pipe
1, PVC pipe (PVC-U pipe) Hard PVC pipe is made of PVC resin, stabilizer, lubricating fluid, etc., and is extruded by pressing method. It is a kind of plastic pipe that has been developed, designed and used for a long time. PVC-U pipe has strong corrosion resistance, easy adhesion, low price and hard material. However, due to the leakage of PVC-U and additives, it is only suitable for water supply systems with ambient temperature not exceeding 45℃. Plastic pipes are used in drainage pipes, sewage, chemicals, heating and freezing liquids, food, ultra-pure liquids, mortar, gas, air compression and ultrafiltration devices.
2. Aluminum plastic pipe is a popular pipe fitting in the market at present. Because of its light weight, durability and convenient construction, its deformability is more suitable for home decoration. The inner surface of aluminum-plastic pipe is made of unique pe material, which is non-toxic, clean and smooth. It can be used for more than fifty years. The aluminum layer in the middle can block 100% vapor permeation, which makes the pipeline have the advantages of both metal material and plastic pipeline, and removes its own defects.
What is a pvc pipe?
1, what is a pvc pipe? PVC pipe (UPVC pipe) Rigid PVC pipe is made of PVC resin, stabilizer and lubricating liquid. And extruding by a pressing method. It is a kind of plastic pipe that has been developed, designed and used for a long time. Aluminum-plastic pipe is a popular pipe fitting in the market at present. Rifeng and Jinde are very famous in the sales market. Because of its light weight, durability and convenient construction, its deformability is more suitable for home decoration. Just buy a PVC tee with a quarter of the inner line and a plastic tee with a quarter of the outer line. They will understand when they arrive at the store, and tell them that PVC must be connected with aluminum-plastic pipes.
2.PVC (full name: Polyvinylchlorid) is polyethylene, and other components are added to improve its temperature resistance, ductility and plasticity. The top layer of this protective film is paint, the main component in the middle is polyethylene, and the bottom layer is adhesive. It is a kind of composite material which is deeply loved, popular and widely used in the world today. Among all kinds of composite materials, its global demand ranks second. According to the survey, only in 1995, the total output of PVC in Europe will be around 5 million tons, and its consumption will be 5.3 million tons. In Germany, the average production, sales and consumption of PVC is1400,000 tons.
3.PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market and soft PVC accounts for 1/3. Soft PVC is generally used for the surfaces of wood floors, suspended ceilings and leather products, but its application range is limited because it contains plasticizer (which is also the difference between soft PVC and hard PVC) and its mechanical properties are weak (if the water inlet pipe must bear certain pressure, soft PVC is not suitable for application). Rigid PVC contains no plasticizer, is easy to form, has good mechanical properties, and has great research and development value. In the production process of polyethylene raw materials, stabilizers, plasticizers and other modifiers must be added. If all environmental modifiers are selected, PVC pipes are also nontoxic and odorless environmental products.
