Ultra high molecular weight polyethylene plate so high wear resistance, so that the abrasion test method with the general plastic difficult to test their degree of wear resistant liner manufacturers use coal bunker, which designed a mortar abrasion testing device. UHMWPE wear resistance and molecular weight is proportional to the wholesale coal bunker with wear-resistant liner, with a molecular weight higher coal bin liner wear manufacturer, its better wear resistance. UHMWPE identification methods: Weighing law. Pure ultra high molecular weight polyethylene products made of gravity between 0.93-0.95, lower density, can float on water. If it is not pure polyethylene material, it will sink to the bottom. Temperature measurement. Pure UHMWPE products, at 200 degrees Celsius will not melt, will not be deformed, but become soft. If it is not pure UHMWPE material at 200 degrees Celsius there will be deformed.
