Modification Of UHMW-PE Sheet
There have been many reports on the performance, processing technology, modification and application of ultra-high molecular weight polyethylene. There are few reports on the performance test of friction and wear in China, while ultra-high molecular weight polyethylene is resistant to wear and tear. Resilience and so on have attracted people's attention and application.
Although ultrahigh molecular weight polyethylene sheet has many excellent properties, it also has many disadvantages such as low hardness, low strength, poor temperature resistance, and poor creep properties. In order to compensate for these deficiencies and further improve the wear resistance, it may be modified with a filler (ultrafine glass microbeads, molybdenum disulfide, talc, glass fiber, carbon fiber, polytetrafluoroethylene).
Ultra-high molecular weight polyethylene sheet is a new type of engineering plastic. It was invented by German scientists in 1958. It was industrialized in foreign countries in the late 1960s. It was officially put into operation in the late 1970s. It has It is excellent in wear resistance, corrosion resistance, impact resistance, self-lubrication, small friction coefficient and low temperature resistance. It is called "magic plastic" in foreign countries. In addition, different modifications should be made according to the conditions and requirements of the application conditions.
