PVC is PVC, bright color, corrosion-resistant, strong and durable, because in the manufacturing process added plasticizer, anti-aging agent and some other toxic auxiliary materials, so its products generally do not store food and medicine.
PVC is actually a vinyl polymeric substance. Simply put, the aqueous solution of the salt is chemically decomposed in the current action. This process produces chlorine, caustic soda and hydrogen. Refining, cracking oil or gasoline can produce ethylene. When chlorine and ethylene are mixed, two vinyl chloride is produced and ethylene dichloride can be converted to produce vinyl chloride, which is an essential component of polyvinyl chloride. The polymerization process connects vinyl chloride molecules together to form a PVC chain. The polyvinyl chloride produced in this manner is in white powder form. It cannot be used alone, but it can be mixed with other components to produce many products.
