One product of PVC pipe industry status quo as technological development, PVC pipe in everyday life can and striking. In Europe, 1980 - 1990 growth of plastic pipes for 8% pvc pipe prices in 2001, annual production of 3.5 million tons, of which 60 per cent of PVC pipe. 1985 US production was 1.6 million tons of plastic pipe, 1999 annual output of about 3.6 million tons, of which, PVC pipe accounted for 78%. China's first root UPVV flared tubing is in a plastic factory in Shenyang in 1983 the birth, then, China has the PVC, drainage capacity. The late 1990s is the period of rapid development in China PVC pipe. During some of the annual production capacity of 5 million tons of plants are built and put into production, million tons of PVC pipe factory production scale up to more than 30. Annual production capacity of 2 million tons of plastic pipe. PVC resin industry is the basis of type and energy-intensive industries, subject to demand and energy prices, greater impact, but it is also a basic chemical raw materials, and is therefore also very closely associated with economic development. From the 2012 situation, the domestic PVC resin capacity is still declining, while the downstream demand growth is relatively slow, coupled with exports, imports increased household pvc pipe, so the domestic PVC resin overall operating rate is not high pvc pipe Plant, a large number of idle capacity pvc pipe, market prices remain in low levels, the price range is reduced. In addition, polyvinyl chloride resins listed futures increased to some extent uncertain PVC resin market price fluctuations sex. Looking to the next few years, China's PVC resin industry will be in a more difficult period of consolidation, there are a variety of factors will influence the future development of PVC resin in China. pvc Features 1. amorphous material, moisture absorption, poor mobility, in order to improve mobility, prevent air bubbles, should advance to dry. 2. easy to decompose, especially at elevated temperatures in contact with steel, copper easier decomposition (decomposition temperature of 200 degrees). Forming small temperature range, the material temperature must be strictly controlled. 3. When using screw injection machine and straight nozzle aperture should be large, to prevent stagnation dead material. 4. Die casting system should be thick, the gate should be large cross-section, the mold should be cooled, the mold temperature 30-60 degrees, the material temperature 160-190.
