Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.
Ultra-high molecular weight polyethylene (UHMW-PE) is the role of special catalyst, polymerization of viscosity-average molecular weight greater than 2.5 million engineering thermoplastics. Ultra high molecular weight polyethylene pipe with high wear resistance, friction coefficient is extremely small , impact resistance , corrosion resistance, non-scaling , the excellent anti- pressure strength , resistance to environmental stress cracking resistance, good self-lubricating , anti-stick attached , unique low temperature resistance , excellent chemical stability, superior performance , is the most cost-effective pipeline was wearable , long-term at -269 degrees to +80 degrees working conditions , are widely used in metallurgical and mining beneficiation , power plants, grain silos , acid and alkali transport , tailings, slurry and coal transportation , terminals, shipyards, oil, natural gas , textiles, paper , food, chemical , mechanical, electrical and other industries.
Can be a lot of use in wastewater treatment , pipelines , there are pipeline external corrosion requirements for long-distance transmission of great significance ; due to the thermal conductivity of this pipe is not ten thousand times smaller pipe , can greatly reduce the cost of transporting pipe insulation for the winter in cold regions and transportation of crude oil and other materials are of great significance , can be replaced by stainless steel, wear-resistant alloy tube , plastic composite pipe and other special pipe.
1 wear characteristics
Ultra-high molecular weight polyethylene pipe molecular weight of up to 250 million more than the tube , the friction coefficient is extremely small , it has a high resistance to sliding friction capability. Wear six times higher than normal alloy steel , stainless steel, 29 times . Is 19 times the phenolic resin , nylon six seven times , five times polyethylene , greatly improve the life of the pipeline.
2 the corrosion resistance
UHMW-PE is a saturated molecules structure, so its high chemical stability, corrosion resistance of the product can be harsh chemicals , strong acids except for some slight corrosion at high temperatures , as in other lye , acid in from corrosion. Can be used in a concentration of less than 85% of concentrated hydrochloric acid at a concentration of less than 80% sulfuric acid , nitric acid concentration of less than 20% of the performance is quite stable.
3 anti- impact resistance
In the existing engineering plastics highest impact toughness of ultrahigh molecular weight pipeline , many materials in serious or repeated shock of the explosion would crack , damaged, broken or surface stress fatigue . The product according to GB1843 standards, Izod impact test without damage, and strong to withstand external shocks, internal overload and pressure fluctuations.
