The unique properties of ultra high molecular weight polyethylene plate performance analytic ultra high molecular weight polyethylene plate of higher than normal polyethylene liner, ultra high molecular weight polyethylene liner has outstanding impact resistance, stress cracking resistance, high temperature creep resistance, low coefficient of friction, self-lubricating, excellent chemical resistance, anti-fatigue ultra high molecular weight polyethylene plate is a plastic sheet, is now gradually been widely used, because the sheet structure is more unique, with high watertight, non-stick material, impact resistance, (not easy to rattle) high abrasion, acid, corrosion resistance, anti-aging. Especially in the case of low temperature in the northern region can reach minus 85 ℃ is also having excellent ductility, utilization rate is relatively high. So special performance of ultra high molecular weight polyethylene plate UHMWPE panel shows a special performance, storage device power plants across the country, the ultra high molecular weight polyethylene plate there is a strong modification in the production process also there will be many changes. First, wear modified: Disposal too molybdenum disulfide, graphite, ultrafine carbon black, carbon fiber, ultra-fine glass beads, polytetrafluoroethylene, etc. can decrease the friction coefficient, wear progress; and to participate in rubber, polyurethane and so the progress of the coefficient of friction. 2, followed by heat-resistant modification: after disposal crosslinked by plasma, can increase the use of UHMWPE temperature reached 200 ℃; filling in UHMWPE coupled disposition over inorganic filler (e.g. glass beads, talc, silica fume stone, mica, calcium carbonate, etc.) can significantly improve the heat distortion temperature HDT. 3, is ultimately modified mechanics: with carbon fiber, glass fiber, ultra-fine glass beads, talc, mica, kaolin, calcium carbonate, aluminum oxide, acicular wollastonite, silica filled, can improve UHMWPE strength, hardness, rigidity and other targets. For ultra high molecular weight polyethylene sheet, in general strongly acidic environment UHMWPE sheet can normally use, and have similar life under normal environments. At a concentration of more than 20% nitric acid or ultra high molecular weight polyethylene sheet situation appeared traces of corrosion in the case of more than 75% concentration sulfuric acid, and life will severely reduce this kind of work environment are rare, so we The following conclusions can be made, in the case of UHMWPE sheet acids having corrosion resistance can be assured. It is the main reason for the temperature hydrochloric acid on the corrosion, ultra high molecular weight polyethylene sheet is available in concentrated hydrochloric acid in the 80 ℃. Ultra high molecular weight polyethylene sheet as a powder, density is 0.936 ~ 0.964g / cm3, non-toxic, easy to absorb water, easy adhesion and no surface attractive; unique mechanical properties and chemical properties, which focused almost entirely on the merits of various plastics, ordinary polyethylene and other plastics unmatched wear resistance, self-lubricating and noise attenuation; impact resistance, low temperature, low-temperature impact; high temperature creep, good thermal stability, melting temperature of 190 to 210 ℃, thermal deformation temperature of 85 ℃ (at 0.46MPa below), the melt flow rate is close to zero; good cold tolerance, brittle transition temperature lower than 140 ℃; resistance to tensile strength of up to 39.2MPa; corrosion and environmental cracking performance is Okay. However, ultra-high molecular weight polyethylene sheet resistance, chemical resistance, in addition to strong oxidizing acid, at a certain temperature and depth ability of various corrosive media; density, are lower than other engineering plastics density, so its products are very lightweight; overall performance and health non-toxic, easy adhesion, easy to absorb water, etc., the fact is there is not a simple score in both materials so many excellent performance.
