As one of the products of technological development, PVC pipe in everyday life can and striking. In Europe, 1980 - 1990 growth rate was 8% plastic tube, 2001 annual production of 3.5 million tons, of which 60 per cent of PVC pipe. US 1985 production of 1.6 million tons of plastic tubes pvc pipe fittings, 1999 annual output of about 3.6 million tons, of which, PVC pipe accounted for 78%. And China's first root UPVV flared pipe is in 1983 born in Shenyang plastics factory, after the Chinese mainland with a PVC, drainage capacity. The late 1990s is the period of rapid development in China PVC pipe. During some of the more than 50,000 tons annual capacity of the plant gradually put into operation, tons more than the scale of production of more than 30 PVC pipe factory. Annual production capacity of 2 million tons of plastic pipe. PVC, Chinese name PVC, a thermoplastic resin formed by the polymerization of vinyl chloride in the role of initiator. PVC pipe is usually done by a plastic particles processing of raw materials, with a screw extruder to prepare a particle, the plastics fuller, easier to process, especially the process of injection molding products. Most plastics molding equipment using a screw machine pvc pipe prices, it passes through the heat transfer external power and external heating element will be solid conveying plastic, compaction, melt extrusion shear mixing. Screw extruder, both as plastics granulation machine or molding machine occupies an important position, strictly speaking, with the special requirements of PVC products, pvc pipes, PVC modified formula is tailored according to customer requirements. There is the PVC copolymers derived from the production process.
