PVC is the abbreviation of (Polyvinylchlorid), the main component of which is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. It is a popular and widely used synthetic material in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, and its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averaged 1.4 million tons. PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc., and is extruded by hot pressing. It is the earliest plastic pipe to be developed and applied. PVC-U pipes have strong corrosion resistance, are easy to bond, are cheap, and have a hard texture. However, due to the leakage of PVC-U monomers and additives, they are only suitable for water supply systems with a conveying temperature not exceeding 45°C. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling liquids, food, ultrapure liquids, mud, gas, compressed air, and vacuum system applications. PVC-O pipes, Chinese name biaxially oriented polyvinyl chloride, are the latest evolution of PVC pipes. Pipes manufactured through a special orientation process will be axially stretched and radially stretched for PVC-U pipes produced by extrusion, so that the PVC long-chain molecules in the pipes are arranged regularly in biaxial directions, obtaining a new type of PVC pipe with high strength, high toughness, high impact resistance, and fatigue resistance.
