>Wear-resistant ultra-high molecular weight polyethylene board is the first choice for coal bunker wear-resistant linings, Shandong Huahong is cost-effective > Wear-resistant ultra-high molecular weight polyethylene board is the first choice for coal bunker wear-resistant linings in Shandong Huahong is cost-effective > Wear-resistant ultra-high molecular weight polyethylene board coal bunker wear-resistant lining It is a thermoplastic engineering plastic, which is made of ethylene and butadiene monomers under the action of a catalyst Polymerized, German scientists invented the synthesis method, and by the century At the end of the year, industrialized production was realized abroad. It combines the superior properties of most plastics. Ultra-high molecular weight polyethylene composite materials have good impact resistance, low temperature resistance, wear resistance, chemical corrosion resistance, self-lubrication, and small friction coefficient. These properties are among the best among plastics at present. OK Ultra-high molecular weight polyethylene is widely used in machinery, transportation, textiles, papermaking, agriculture, food packaging, coal mining, chemical industry and other fields. > Wear-resistant ultra-high molecular weight polyethylene board coal bunker wear-resistant lining When used in the ore loading process, ore blockage and sticking to the bunker often occur , which strictly affects the effect of ore shipment. If manual processing is used, there will be great safety risks. The excellent physical and mechanical properties and stability of ultra-high molecular weight polyethylene boards prove its feasibility as the inner wall lining of the ore silo. A large number of experiments have shown that there are huge differences in the wear resistance of ultra-high molecular weight polyethylene plates and metals such as stainless steel and steel. There are mainly two reasons: on the one hand, due to the Self-lubricating, its friction coefficient is very small, while stainless steel and steel have large friction coefficients. On the other hand, due to the structural differences between ultra-high molecular weight polyethylene sheets and metal materials, metals are composed of crystals , a crystalline material, composed of atoms of elements in the form of a lattice. Each unit cell has only a few atoms. The binding force between unit cells is the main valence force, which is combined by metallic bonds and covalent bonds. The metal is filled with Free electrons can be regarded as steel bodies or elastic bodies. Ultra-high molecular weight polyethylene board is composed of crystalline region and amorphous region. It is a semi-crystalline material composed of macromolecules with a molecular weight greater than . It has no free electrons and can be regarded as a viscoelastic body. It can be seen that their physical, chemical, mechanical properties and surface properties vary greatly. Therefore, the tribological behavioral characteristics displayed are also different. > Wear-resistant ultra-high molecular weight polyethylene board coal bunker wear-resistant lining Has good impact resistance, low temperature resistance, chemical corrosion resistance, self-lubrication, and friction The coefficient is small and has good wear resistance, so it is the best composite material for lining the mine. According to the actual conditions of the mine, ultra-high molecular weight polyethylene plates can be installed in the space between two adjacent rails. slot and secure with crash bolts. The installation range of ultra-high molecular weight polyethylene board material should include the entire inclined wall and extend to the resin wall , Considering the price of ultra-high molecular weight polyethylene material, the empty grooves of the two rails can be filled first A certain height of high-strength concrete, the thickness of ultra-high molecular weight polyethylene board is generally recommended > Wear-resistant ultra-high molecular weight polyethylene board coal bunker wear-resistant lining< br/>Excellent characteristics Not only impact resistance, low temperature resistance, chemical corrosion resistance, self-lubrication, small friction coefficient, but also strong wear resistance < br/> The wear resistance is much stronger than that of stainless steel and , about times. As the impact speed increases, the wear rate of ultra-high molecular weight polyethylene increases slowly, while the wear rate of stainless steel and steel increases rapidly. Although ultra-high molecular weight polyethylene sheets have strong wear resistance and impact resistance, no matter how good the material is, it will be damaged. Therefore, production management must be strengthened, such as when loading ore. When using, try to let the ore fall from just above the center of the funnel mouth to reduce the impact and wear on the lining plate. |
