Self-lubricity of ultra high molecular weight polyethylene sheets
Ultra-high molecular weight polyethylene sheets are self-lubricating, and the polyethylene sheet has a melting point of one hundred and thirty degrees and a relative density of less than one. Polyethylene sheet has its own unique heat resistance and cold resistance, and it also has a stable chemical stability function. In addition to these polyethylene sheets, they also hold high rigidity and durability, and the mechanical strength is also good. The ultra-high molecular polyethylene sheet also has a dielectric function, and the ring-resistant stress cracking resistance is very good. Ultra-high molecular weight polyethylene wear-resistant plate series, the company’s various wear-resistant products are widely used in powder preparation and ultra-fine processing of ball mill equipment in cement, building materials, metallurgy, mining, thermal power plants, ceramics, refractory materials, etc. The product has many characteristics such as high strength, high hardness, high wear resistance, high temperature resistance, impact resistance and low breakage rate, which can greatly improve the production capacity of the enterprise, reduce the production cost of the enterprise, and reduce the labor intensity of the workers. It has an extremely low friction factor (0.05 to 0.11) and is therefore excellent in self-lubricating properties. Compare the friction factor between UHMWPE and other engineering plastics. It can be seen that the UHMWPE’s dynamic rubbing factor is 1/2 of PA66 and POM under water lubrication conditions, which is second only to plastic self-lubricating polytetrafluoroethylene (PTFE) in the absence of lubrication; when it slides When working in a rotating form, it is more lubricious than steel and brass. Ultra high molecular weight polyethylene sheet excellent low temperature resistance can be used as a low temperature resistant component of the nuclear industry; clean and non-toxic excellent function, can be applied to food, clean occupation; vacuum box panel, dewatering plate, scraper, sealing strip, etc. Applicable to the papermaking profession; it can be applied to beverage food machinery, etc. by using abrasion resistance, impact resistance, non-bonding, clean and non-toxicity. UHMW Sheets can also be used in textile machinery, equipment and other occupations. The extremely high molecular weight of the ultra-high molecular weight polyethylene sheet gives it excellent application functions, its good function, and the supply of moderate, well-established thermoplastic engineering plastics, which concentrates on the advantages of various plastics, usually with polyethylene and other engineering. Plastic can not match the wear resistance, impact resistance, corrosion resistance, self-lubrication, absorption of impact energy, low temperature resistance, non-toxicity, adhesion is not easy, not easy to absorb water, induce low density.
