PVC, that is, polyvinyl chloride, is a polymer polymerized by vinyl chloride monomer according to the free radical polymerization mechanism. It is a general resin material.
PVC is a kind of material with flame retardancy, good chemical stability and low tensile cracking internal force. At the same time, its material characteristics include high strength, high rigidity and high hardness, and its working temperature ranges from-15 to 60 degrees, so it can be bonded and welded.
The main characteristics of PVC: strong corrosion resistance: the most suitable anti-corrosion equipment for chemical industry. Easy to process: cutting, welding and bending are extremely simple. High strength, high rigidity and high hardness; Good electrical insulation; Good chemical stability; Self-extinguishing; Low water absorption; Easy to bond and paint. Low price.
Application fields of PVC: acid test tower, seawater concentration tank, photo processing equipment, electroplating bath, battery box, electric meter board, audio seat cover, radio base plate, various electrical insulation boards, cement tank lining, mechanical wind shield, exhaust pipe engineering, stationery, building materials, etc.
In the process of processing PVC into finished products, various chemical additives will be added, some of which have great influence on human health. Although PVC is used in medical devices and food machinery, it is a designated product of designated factories. Without knowing the source and expected use of PVC, PVC should not be used in food processing.
