Detailed Product Description: | Ultra-high molecular weight polyethylene pe plate High strength, impact resistance, fatigue resistance, non-toxic, tasteless, Operating temperature -70 to +100 ° C, has been widely used in various silos, hoppers, chutes, pipes, slag ditch lining and wear resistance of mechanical parts is to solve the anti-wear, anti-blocking, anti-corrosion of an ideal material. Abrasion resistance: stainless steel equivalent of nine times, 6-7 times that of PTFE, of HDPE. Viscosity: surface tension, the common material incompatibility, so easy adhesion scaling. Corrosion resistance: ability phosphoric acid, hydrochloric acid, dilute sulfur suan, bases, salts and other corrosion. The friction coefficient: flow to mention the resistance, saving energy. This product is the main application areas: power plants, mines, shipyards, coking plants, fertilizer plants, steel mills, docks, auto parts company, sewage treatment plant, construction vehicles and so on. Plate specification: 1500 × 1300mm 2000 × 1300mm 3000 × 1300mm, 4000mm × 1300mm, 5000mm x 1300mm, 6000mm x 1300mm. Thickness of 10mm to 200mm ultra-high molecular weight polyethylene with molecular chain length is 10 to 20 times that of the high-density polyethylene. Longer molecular chains (higher molecular weight) to give of UHMWPE main advantage of toughness, wear resistance and resistance to stress cracking resistance. Since it is a kind of polyethylene, UHMWPE has lubricity, chemical resistance and excellent electrical properties of the generic HDPE. Long molecular chains to make the materials difficult to machine in a common molding and extrusion equipment. Heated to above the melting point of UHMW become transparent, but does not flow. The chemistry and properties of UHMWPE is legally produced with Ziegler polyethylene. Processing requirements of particularly high purity ethylene monomer impurity control in a few parts per million. The product is a white powder, similar particle size and salt. The polymer solution viscosity method to detect the basis of intrinsic viscosity (IV) and molecular weight (MW). UHMWPE according to ASTM definition of the weight average molecular weight (MW) greater than 3 million. Existing UHMWPE grades of MW between 300 to 600 million. Generally in accordance with Category IV, IV 20dl. / G is approximately equal to MW to 3 million. IV of 30 MW to 600 Million. Some grades contain additives for a particular end-use applications. Usually UHMW feed additive can be sintered and wrought without stabilizer. Processing conditions, including the hour and 0.5 tons / square inch or higher pressure conditions, UHM3V can be solidified into a block, plate, or a simple extrusion pressure in the 392F temperature. Under these conditions, the occurrence of some oxidative cross-linking. If the material is crosslinked become insoluble the UHMWPE IV value can not be accurately measured. The appropriate cross-linked with peroxide for the enhanced wear resistance. UV resistance or to extend the heat resistance add UV stabilizer or antioxidant. UHMWPE has exceptional performance, especially the wear resistance (than carbon |
