Ultra high molecular weight polyethylene (UHMWPE) mine lining plate product information
First, material characteristics
Molecular weight and structure
Molecular weight range: 3 million ~6 million, the molecular chain is highly wound, giving the material superior wear resistance and impact resistance.
Crystallinity: 50%-70%, both rigid and toughness.
Physical property
Density: 0.93~0.94 g/cm³ (only 1/8 of steel, significant lightweight advantage).
Friction coefficient: 0.07~0.12 (excellent self-lubrication, reducing material adhesion).
Wear resistance: 7 times that of carbon steel, 4 times that of nylon, suitable for high wear environment.
Chemical property
Corrosion resistance: acid, alkali, salt and organic solvent (such as sulfuric acid, nitric acid concentration ≤80%).
Low temperature resistance: stable performance within -269℃~80℃, no risk of embrittlement.
Second, product application scenarios
Mining domain
Ore conveying system: Used in chute, hopper, shaker liner to reduce material clogging and noise.
Storage and transportation equipment: mine car, mine bin lining, prolong the life of the equipment.
Beneficiation equipment: flotation cell, spiral classifier lining, reduce metal pollution.
Other industrial fields
Coal bunker of thermal power plant, coke conveying in coking plant, chemical material pipeline, etc.
Third, core advantages economy
The service life is 3 to 5 times that of the traditional metal liner, and the maintenance cost is reduced by more than 40%.
No anti-corrosion coating is required and maintenance free after installation.
Environmental protection and safety
Comply with RoHS and ISO 14001 standards, no risk of heavy metal precipitation.
Friction-free sparkless characteristics, suitable for flammable and explosive environments (such as coal mines).
