The superior performance of ultra-high molecular weight polyethylene wear-resistant liner performance plastics, with wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, low temperature resistance, small wear coefficient, light weight, energy absorption, aging resistance, flame retardant, anti- Static electricity and other excellent properties. Use ultra-high molecular weight polyethylene wear-resistant lining board UHMW-PE sheet to line coal bunkers in power plants, coal mines, coking plants, etc.; ore silos and other material silos in cement plants, steel plants, and aluminum plants; granaries in grain, feed, and pharmaceutical industries , dock hopper, etc., can prevent sticking materials, speed up the unloading speed, prevent blockage accidents, save the investment and cost of air bubbles, lining the bulk cabin can prevent powder from adhering to the cabin and reduce the damage of loading and unloading machinery to the cabin wall. With the development of plastic processing technology, the application field of UHMW-PE will be broader.
Ultra-high molecular weight polyethylene lining of screw conveyor :
1. Non-stick material: the surface adsorption force is very weak, its anti-adhesion ability is second only to PTFE, the water absorption rate is almost zero, only 1% of PA6, coal dust, wet Soil, laterite, and other highly viscous materials will not stick to it even if the humidity is high, and the sliding speed of the material has nothing to do with the humidity factor.
2. Wear resistance: The wear resistance of polyethylene liner ranks first among engineering plastics, and the wear resistance of polyethylene liner is higher than that of many metal materials (such as carbon steel, stainless steel, bronze, etc.). The abrasion index of mortar is only 1/5 of PA66, 1/10 of HDPE and PVC; compared with metal, it is 1/7 of carbon steel and 1/27 of brass.
3. Self-lubricating property: The coefficient of static friction is 0.07, and the self-lubricating property is good, second only to polytetrachloroethylene (PTFE) under the condition of no lubricant; the lubricity is better than that of steel and brass with lubricating oil. It is an ideal lining, the friction part of the equipment, in addition to improving the wear-resistant life, it can also receive energy saving effect.
4. Anti-corrosion: The polyethylene liner is not corroded in lye, and has stable performance in 75% concentrated sulfuric acid and 20% nitric acid. It is also stable to seawater and liquid detergents.
5. Impact resistance: polyethylene liner has large molecular weight and tight chemical bonds. Therefore, it has strong impact resistance and will not break. The impact strength is 10 times that of nylon 66, 20 times that of polyvinyl chloride, and 8 times that of PTFE; the impact strength is about 2 times that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP. Especially in the low temperature environment, its impact strength reaches the highest value, and its flexibility can provide a very safe and reliable guarantee for the conveying system.
