How To Improve The Overall Quality Of UHMWPE Pipe
Ultra high molecular weight polyethylene (UHMWPE) is a linear structural polyethylene with a viscosity average molecular weight of more than 1.5 million (the relative molecular mass of ordinary polyethylene is only 20,000-300,000). The extremely high relative molecular weight gives it superior performance and is a new type of thermoplastic engineering plastic with excellent performance. Due to its extremely high molecular weight, it concentrates almost all the advantages of plastics.
It has the unmatched corrosion resistance, impact resistance, self-lubrication, corrosion resistance, low temperature resistance, hygienic non-toxicity, non-adhesion, non-absorption and other comprehensive properties of ordinary polyethylene and other engineering plastics. It is superior in solid particles, powders, slurries, and gas transport. Known as "amazing plastic". In recent years, due to breakthroughs in plunger push, single screw extrusion and other technologies.
The ultra-high molecular weight polyethylene pipe has also achieved industrialized continuous production in China. However, due to the characteristics of the ultra-high molecular weight polyethylene raw material, the processing of ultra-high molecular weight polyethylene pipe is difficult. Although the production of ultra-high molecular weight polyethylene pipe realizes continuous extrusion of plastic extruder, its production speed is only ordinary plastic. The production speed of pipe products is 1c/o, and the wear resistance index of pipes can only reach 60c/o of the wear resistance index of developed pipe products in Western Europe.
Increasing the production speed of ultra-high molecular weight polyethylene pipes and improving wear resistance have become the focus of research in the industry. In recent years, the application range of ultra high molecular weight polyethylene pipes has been expanding. It is precisely because the ultra-high molecular weight polyethylene pipe has excellent properties such as friction resistance, corrosion resistance, impact resistance, self-lubrication, non-adhesion, non-absorption, and the like. Market awareness has gradually increased.
