Black ultra-high molecular polyethylene wear-resistant liner performance:
1. Wear resistance
The abrasion resistance of ultra-high molecular weight polyethylene coal bunker liner ranks the highest among plastics and exceeds some metals. The mortar abrasion index of UHMWPE is only 1/5 of that of PA66 and 1/10 of that of HDPE and PVC; It is 1/7 of carbon steel and 1/27 of brass.
2. Impact resistance
The impact strength of ultra-high molecular weight polyethylene coal bunker liner is about 2 times that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP.
3. Self-lubricating
The ultra-high molecular weight polyethylene coal bunker liner has a very low coefficient of friction (0.050.11) and excellent self-lubrication. It is second only to the best self-lubricating polytetrachloroethylene (PTFE) in the absence of lubricants; when it works in a sliding or rotating form, it is more lubricating than steel and brass with lubricating oil.
4. Chemical resistance
Ultra-high molecular weight polyethylene coal bunker liner has excellent chemical resistance. Except for strong fluorinated acid solution, it is resistant to corrosive media (acid, alkali, salt) and organic media (except naphthalene solvent) within a certain temperature and concentration range. ).
5. Impact energy absorption
The ultra-high molecular weight polyethylene coal bunker liner has excellent impact energy absorption, and the impact energy absorption value is the highest among all plastics, so it has good noise damping and excellent noise reduction effect.
Application range of black ultra-high molecular weight polyethylene wear-resistant liner in various industries
