The wear resistance of polyethylene sheets ranks highest among plastics and exceeds that of some metals. The mortar wear index of polyethylene sheets is only /, and / compared with metals , is carbon steel/, brass/.
2 Impact Resistance
The impact strength of polyethylene sheet is about 10 times of impact resistance, 0 times, and 0 times, and 1 times.
3. Self-lubricating properties
Polyethylene sheets have extremely low friction coefficient and excellent self-lubricating properties. It is second only to polytetrachlorethylene, which has the best self-lubricating properties under no lubricant conditions. When it works in sliding or rotating form, it has better lubricity than steel and brass with added lubricating oil.
Four chemical resistance
Polyethylene sheets have excellent chemical resistance. In addition to strong fluorinated acids, they can resist corrosive media (acid, alkali and salt) and organic matter within a certain temperature and concentration range. media (except naphthalene solvent).
Five Impact Energy Absorption
Polyethylene sheets have excellent impact energy absorption. The impact energy absorption value is the highest among all plastics. Therefore, it has good noise damping and excellent sound attenuation effect.
6. Non-stickiness
The surface adsorption force of polyethylene sheet is very weak, and its anti-adhesion ability is second only to the best non-stickiness among plastics, so the surface of the product is not easy to adhere to other materials.
Seven hydrophobicity
The water absorption rate of polyethylene sheets is very low, generally less than 0.0%.
It is widely used in coal bunkers, gypsum silos, lime silos, homogenizing silos, cement silos, dump truck mixing barrels in my country's steel, electricity, coal, cement mines and other industries, solving the long-standing bonding bridge wear problem in these parts. Due to problems such as low production efficiency, it is considered by scientific research and design departments to be the best engineering plastic to solve problems such as bonding and wear at present, and it has been vigorously promoted to the industry and has achieved significant economic and social benefits.
