Today to introduce what is high molecular weight polyethylene liner, first of all we have to understand what is liner? The liner is used to protect the cylinder body from direct impact and friction between the abrasive body and the materials, and it can also be used to adjust the movement state of the abrasive body to enhance the grinding effect of the abrasive body on the materials, it can improve the grinding efficiency of the mill, increase the output and reduce the metal consumption.
Why Do You Need a liner? Because mechanical wear involves a lot of aspects, of which abrasive wear accounted for more than 50% of all industrial wear. The United States has calculated that the annual economic losses due to wear and tear accounted for 4% of its GDP, the Australian mining industry annually due to wear and tear loss of 2% of mineral sales. There are two ways to solve the problem: one is to improve the wear resistance of materials, the other is to improve the wear environment from the process. In this mainly from the material aspect to elaborate: 1. It is required that the lining board has good wear resistance. 2. High strength and toughness 3. High performance-price ratio, strong adaptability. Polymer polyethylene plate with wear resistance, corrosion resistance, impact resistance, low temperature resistance, hydrolysis resistance, self-lubrication and other characteristics, can add flame retardant, anti-static properties. It can be used in non-shaft screw conveyor, shaft screw conveyor, sewage treatment conveyor, cement conveyor, cement tanker and so on.
Application of high molecular weight polyethylene Liner:
1.Lining: Coal bin liner, Hopper, Hopper, wear-resistant plate, bracket, chute and other reflux devices, sliding surface, roller, etc.
2.Food Machinery: Guide Rail, Star Wheel, guide gear, roller, bearing liner, etc.
3.Papermaking machinery: suction tank cover plate, guide plate, wiper plate, hydrofoil.
4.Chemical Industry: sealing packing, packing, vacuum die box, pump components, bearing liner, gear, sealing joint surface.
5.Other: agricultural machinery, ship parts, electroplating industry, low-temperature machinery parts.
