Different plastics and traditional materials, faster pace of technological progress, the emergence of new technologies, new materials, new technology to make the advantages of plastic pipe relative to traditional materials and more prominent. Compared with traditional plastic pipe metal pipe and cement pipes, light weight, typically only a metal pipe 1 / 6-1 / 10, has good corrosion resistance, impact resistance and tensile strength than the inner surface of the plastic tube cast iron pipe is smooth and more, low coefficient of friction, fluid resistance, can reduce water consumption by 5% or more, good comprehensive energy, manufacturing 75% lower energy consumption right, easy to transport plastic pvc pipe shaped product, easy to install plastic pvc shaped pipe price, service life of up to 30-50 years. Polyethylene pipe has developed rapidly in the world, the developed countries in the field of water supply and gas field applications accounted for polyethylene pipe absolute advantage. Polyethylene pipes not only a lot to replace traditional steel, cast iron pipe, etc., are still in place of PVC pipe, polyethylene pipe reason is technological innovation. On the one hand there is a significant improvement materials, polyethylene polymerization by improving the production process, the strength polyethylene pipe resin almost 1-fold increase. On the other hand there is a new application of technology development, such as no excavation trench, directional drilling method using polyethylene pipe laying technology into full play the advantages of polyethylene pipe, the traditional pipe for using this method in the case of the fundamental not able to compete. There are a lot of new materials, new techniques are being investigated or have been finding out is to try to test to be sure, in the next 10 years of technological progress plastic pipe plastic pipe will lead to more quickly develop broader. Emulsion and suspension polymerization essentially similar shaped plastic pvc pipe, only to be used a lot more of an emulsifier, and is not soluble in water but soluble in the monomer. Such polymerization system can effectively prevent the aggregation of polymer particles, thereby obtaining a small particle size polymeric resins, latex particle size generally produced PVC resin is 0.1-0.2mm, suspension of 20-200mm. Initiator system and suspension polymerization are different, usually containing persulfate redox systems. The drying method is also designed to maintain a smaller particle diameter mode, often using some spray-drying agent. Since it is impossible to completely remove the emulsifier, and therefore the resins produced by emulsion can not be used for the production of articles that require high transparency, such as packaging films or require very low water-absorbing articles such as wire insulation. Emulsion PVC resin is generally higher than the price of suspension polymerization of resin, but the ingredients in liquid form requires the user to use such a resin, such as a paste resin. In the United States most of the resin emulsion products are paste resin (also known as dispersion resin) supply pvc plastic pipe shaped, small amount for the latex. In Europe, a variety of emulsion processes are also used to produce general-purpose resins, in particular rolling and extrusion resin.
