PVC pipe is a kind of synthetic material that is well-loved, popular and widely used 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, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averaged 1.4 million tons. Today we will introduce the types of PVC pipes.
Different Categories of PVC Pipe.
The PVC Pipe provided by the company.
PVC is the abbreviation of (Polyvinylchlorid), the main component is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive.
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 floors, ceilings and leather surfaces, but because soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC), its physical properties are poor (such as water pipes that need to withstand certain water pressure, soft PVC Is not suitable for use), so its scope of use is limited. Rigid PVC does not contain plasticizers, so it is easy to shape and has good physical properties, so it has great development and application value. In the production process of polyvinyl chloride materials, several additives, such as stabilizers, plasticizers, etc., are bound to be added. If all environmental additives are used, then PVC pipes are also non-toxic, tasteless and environmentally friendly products.
PVC pipes (divided into PVC-U pipes, PVC-M pipes and PVC-O pipes) Rigid polyvinyl chloride pipes are made of polyvinyl chloride resin, stabilizers, lubricants, etc., and then extruded by hot pressing. The first plastic pipe to be developed and applied.
PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the seepage of PVC-U monomer and additives, it is only suitable for water supply systems whose conveying temperature does not exceed 45℃. Plastic pipes are used in drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, mud, gas, compressed air and vacuum systems.
PVC-O pipe, Chinese name biaxially oriented polyvinyl chloride, is the latest evolutionary form of PVC pipe. The pipe manufactured through a special orientation processing process will be stretched and diametrically produced by the extrusion method. Stretching to make the long-chain PVC molecules in the pipe arranged in a biaxial direction to obtain a new type of PVC pipe with high strength, high toughness, high impact resistance and fatigue resistance.
