PVC (full name Polyvinylchlorid), the main ingredients of PVC, while adding other ingredients to enhance its heat resistance, toughness, ductility. This table uppermost layer mask is painted, the main ingredient in the middle of polyvinyl chloride, the lowest layer is coated with an adhesive backing. It is loved by the world, is quite popular and is also widely used as a synthetic material. It's the second highest in the global use of a variety of synthetic materials. According to statistics, in 1995 only one year, PVC production capacity in Europe, there are about five million tons of PVC profiles, while its consumption was 5.3 million tons. In Germany, PVC production and consumption by an average of 1.4 million tons. PVC pipe (PVC-U pipes) Rigid PVC pipe is made of PVC resin and after stabilizers, lubricants, etc. with using hot extrusion method, is the first to get the development and application of plastic pipe. PVC-U pipes strong anti-corrosion, easy adhesion, low prices, hard, but because there are PVC-U monomers and additives exudate, only applies to transport temperature does not exceed 45 ℃ water supply system. Plastic pipe for conveying applications drinking water, wastewater, chemicals, heating fluid and coolant, food PVC profile material, ultrapure liquid Shandong PVC profile, mud, gas, compressed air and vacuum systems. PVC is very hard, very poor solubility, only a few solvent, dissolved in cyclohexanone, dichloroethane, tetrahydrofuran and the like, and organic and inorganic acids, bases, salts are stable, chemical stability with increased temperature reduced. PVC dissolved in acetone - carbon disulfide or acetone - benzene mixed solvent for dry spinning or wet spinning from fiber, called polyvinyl chloride, with flame retardant, acid, anti-microbial, wear, environmentally friendly features and has good thermal resistance and elasticity.
