Products Description
Ultra high molecular weight polyethylene (UHMWPE) lining product information
Applicable industries: mining, chemical, energy, logistics
First, core material characteristics
Ultra high performance polymer
Molecular weight: 3 million ~6 million, the molecular chain is highly cross-linked, forming a dense wear-resistant network structure.
Friction coefficient: 0.07~0.12 (dynamic dry friction), self-lubrication is better than PTFE, reduce material accumulation and energy consumption.
Wear resistance: ASTM D1044 test shows that the wear resistance is 8 times that of high manganese steel, which is suitable for high impact and high wear scenarios.
Environmental adaptability
Temperature range: -269℃ to +80℃ long-term stability (below -100℃ still maintains toughness, no brittleness).
Chemical corrosion resistance: Strong acid, alkali and organic solvent (such as benzene, ethanol) with pH 2~13, excellent seawater corrosion resistance.
Anti-aging: Outdoor service life can reach more than 10 years after the addition of anti-UV agent (ASTM G154 accelerated aging test).
Second, product application scenarios and solutions
Scenario Typical problems UHMWPE lining solution
Mine conveying system ore impact wear, metal pollution 20~50mm thick liner, reduce noise more than 15dB
Chemical pipeline corrosive medium erosion, scaling lining wall thickness of 10~30mm, flow rate increased by 20%
Port unloader coal/ore adhesion, unloading efficiency is low surface micro-texture treatment, anti-adhesion rate >90%
The food processing line has high hygiene standards, needs mildew and antibacterial food grade certification (FDA) lining, and zero contamination
Third, technical parameters and customized services
