Utra-high molecular weigh polyethylene (UHMW-PE) is a thermolastic engineering plastics, which combincs the advantages of all plastics. It has excellent properties such as wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, low temperature wear resistance, light weight, cnergy absorption, ageing resistance, flame retardant and antistatic. UHMW.PE sheet is used to liner coal bunkers such as power plants, coal mines and coking plants; ore and other material bunkers of cement plants, iron and steel plants and aluminium plants; granaries and whar'hoppers of grain, feed and pharmacutical industries, ete, which can prevent sticking. To speed up the cuting speed, avoid blocking accidents, save the investment and cost ofair guns, and liner the bulk cabin to avoid powder sticking to the cabin and reduce the damage of loading and unloading machincry to the wall of the warchouse. With the development of plastic processing technology, the aplication of UHMW-PE will have a broader prospect.
