Excellent properties of wear-resistant polyethylene sheet

2020-03-01

Wear-resistant polyethylene board is a thermoplastic material with excellent comprehensive performance .. Wear-resistant polyethylene board has strong wear resistance, impact resistance and self-lubrication, and the proportion is light, easy to use, moderate price, and high cost performance .. Wearable polyethylene board is suitable for coal bunkers, silos, funnels and chutes in coal, metallurgy, steel, thermal power, cement, coking, glass, coal washing, smelting and other industries. It can effectively solve the problems of coal bunker, bunker blockage, bonding, bridging and so on in the production of enterprises..

The wear-resistant polyethylene sheet has a very high wear resistance and many application functions in engineering equipment are very valuable. In all current engineering plastics, it is good abrasion resistance, with the increase in molecular weight of ultra-high molecular weight polyethylene, the more abrasive the material. The abrasion-resistant engineering thermoplastic polyethylene sheet is of greater than 1.5 million molecular weight. High-density polyethylene has 10?20 times the molecular chain length, the longer the molecular chain (higher molecular weight) gives the main advantage is that the high molecular weight polyethylene wear plate toughness, wear resistance and stress cracking resistance, because it is polyethylene, ultra-high molecular weight polyethylene wear plate also has lubricating properties, general chemicals and HDPE excellent electrical properties.

The successful development of wear-resistant polyethylene board is generally regarded as one of the top ten scientific and technological achievements in the 20th century. Wear-resistant polyethylene board has excellent wear resistance, good low temperature impact resistance, self-lubricating, non-toxic, Water resistance and chemical resistance .. The wear-resistant polyethylene board has poor fluidity in the molten state and extremely high viscosity .. It is a high-viscosity elastomer in the shape of rubber. It can only be formed by pressing and sintering in the early stage, and can also be processed by extrusion, injection and blow molding methods.
