Polyvinyl chloride is a chlorine atom using a polymer material such as polyethylene in a hydrogen atom. The structure of this material are as follows: [-CH2 -CHCl-] n. Carbon atoms arranged in a zigzag chemical pvc pipe, all atoms are σ bond linked. All the carbon atoms are sp3 hybrid green and low consumption of plastic pipe formulation design, PVC plastic pipe to certain principles formula design. PVC macromolecular structure exist in the head structure unstable structure, branched chain, a double bond, allyl chloride, tert-chloride and the like, so that the thermal deformation resistance and poor aging drawbacks. Pretending to be cross-linked, can eliminate this class disadvantage. PVC material is polyvinyl chloride, which is a very versatile material, often used in our lives. Such as PVC pipe, PVC floor, PVC wallpaper and so on. India's market demand for PVC is increasing year by year brand-name pvc pipe, PVC future India will continue to rely on imports to add. 1, PVC classification of different production methods, PVC can be divided into: general-purpose PVC resin, a high degree of polymerization of PVC resin, crosslinked PVC resin. General-purpose PVC resin is a vinyl chloride monomer in the role of initiator formed by polymerization; high degree of polymerization of PVC resin is a vinyl chloride monomer was added to the polymerization system chain extender polymerization of the resin; crosslinked PVC resin added vinyl chloride monomer polymerization system resin diene and polyene polymerized cross-linking agent containing. PVC is the growth rate of 4% to obtain production and application worldwide. PVC growth in Southeast Asia is particularly significant pvc pipe, thanks to Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material properties of the material ABS (acrylonitrile - butadiene - styrene) ABS is used to transport drinking water, mud and chemicals. The most common DWV (drain waste vent) applications. Unplasticized polyvinyl chloride (UPVC) and CPVC (post-chlorinated polyvinyl chloride) having an inner UPVC entire operating temperature range excellent chemical resistance, have a wide operating pressure belt. Due to the nature of long-term high strength, rigidity and cost-effective hardware pvc pipe, UPVC systems account for a large proportion of plastic pipe installation. CPVC is resistant to many acids, alkalis, salts, paraffins, halogen and alcohols. This is not an anti-solvent, aromatic hydrocarbons and certain chlorinated hydrocarbons. PP (polypropylene) Polypropylene is suitable for use in food, drinking water and ultra-pure waters, as well as in the pharmaceutical, chemical and other industries. PE (polyethylene) Polyethylene has been used successfully for many years drinking water and waste water, hazardous waste, and the compressed gas is safely transported. pvc pipe production line, pvc pipe, sea Widex Widex provided by Qingdao Rubber Material Co., Ltd.
