Ultra-high molecular weight polyethylene (UHMWPE) is a new type of engineering plastic. The synthesis method of UHMWPE was invented by German scientists in 1958, and industrialized production was realized abroad by the end of the 1960s. my country's official production began in the late 1970s and early 1980s. It has excellent characteristics such as wear resistance, corrosion resistance, impact resistance, self-lubrication, small friction factor, and low temperature resistance.
Although ultra-high molecular weight polyethylene has many excellent characteristics, it also has many shortcomings: low hardness, low strength, poor heat resistance, creep, etc. In order to make up for these shortcomings and further improve its wear resistance, it can be filled with fillers (ultra-high molecular weight polyethylene). Fine glass microbeads, molybdenum disulfide, talc, glass fiber, carbon fiber, polytetrafluoroethylene) modification. In addition, different modifications should be carried out according to the industrial and mining conditions and requirements of its application. The author used the M-200 friction and wear testing machine to carry out the friction and wear test of the ring (45# steel) block, and carried out the ultra-high molecular weight polyethylene mortar wear test on the corrosion and wear testing machine.
