With the development of the global economy in the new century, China's high-tech rapidly penetrate into the coal, electricity, metallurgy, cement and other industries, and promote the rapid development of these industries. But the common bond in these industries and coal bunker, hopper, chute, mixing barrel, bridges, wear has become a stumbling block to hinder the development of these industries forward, in order to solve these problems, I sold the UHMW- PE ultrahigh molecular weight polyethylene plastic liner ring nano composite alloy resistant liner, polyurethane liner, nylon lining and so has a high abrasion resistance, impact resistance, anti-static, self-lubricating, corrosion-resistant, non-absorbent, light weight , good stability, non-toxic and tasteless, and coefficient of friction, not bonded, long life, easily damaged, flexible operation, convenient maintenance and other advantages. The product can also reduce noise, save power, reduce labor intensity, improve efficiency, increase economic efficiency, and therefore can not be replaced by other similar products, is also the users and the design of units for many years and recognized the ideal product. Create a lot of social and economic effect of China's economic construction. Is the ideal wear-resistant materials for coal, electricity, metallurgy, cement and other industries preferred.
