The application of ultra-high molecular weight polyethylene liner in coal mine industry has broad prospects.Because the material has high wear resistance,low friction coefficient,impact resistance,low cost,good processing properties and other characteristics,can be made of coal mine machinery bearing,bushings,plate using the material,the filter board,spraying machine friction plate and plate etc..In this way,not only the service life is prolonged,but also the work efficiency is improved,and great economic and social benefits can be brought.The use of ultra high molecular weight polyethylene for road materials can not only save a lot of iron and steel,reduce labor intensity,but also reduce the slope of the original chute and increase the output of coal.After adopting the ultra-high molecular weight polyethylene lining,the coal bunker can improve the storage capacity of the coal bunker and prevent the blockage.Ultra high molecular weight polyethylene(PE)is used as screen plate of vibrating coal screening machine in coal washing plant,which can reduce noise and improve working environment.In addition,ultra high molecular weight polyethylene can also be used in the manufacture of coal pipelines,filters,scrapers and other materials.
