The report notes that in 2015, the country new construction, renovation, expansion project, 85% of plastic sewer pipe construction, building rainwater drains 80% plastic pvc plastic pipe, plastic pipe city sewer usage reaches 50%, building water supply, hot water supply and heating pipe 85% of the plastic pipe, city water pipe (DN400mm below) 80% of the plastic pipe pvc plastic prices, rural water supply pipes 90% plastic pipe, city gas plastic pipe (low pressure tube) Application volume reached 40%, building wire threading sheathing 90% of the plastic tube. It is predicted that production of plastic pipes during the second five will remain at about 10% growth rate in 2015 pvc plastic products, production of the country is expected to be close to 12 million tons of plastic pipes, plastic pipes in various national pipeline market share of over 60%. PVC plastic is composed of liquid vinyl chloride monomer (VCM) by suspension polymerization, emulsion, bulk or solution process from which the suspension polymerization process mature production technology, simple operation, low production costs, product variety, a wide range of applications, has been the main method of production of PVC resins, PVC production facility in the world approximately 90% of the proportion (in the world production of PVC homopolymer also accounted for about 90% of the scale). Followed by emulsion method for the production of PVC paste resin. Its polymerization by a free radical initiator, the reaction temperature is generally 40 ~ 70OC, reaction temperature and concentration of the initiator of the polymerization reaction rate and the molecular weight distribution of PVC resin great influence.
