Super wear-resistant polymer tube (ultra high molecular weight polyethylene "UHMW-PE") known as the magical plastic, has the following characteristics: wear seven times higher than PTFE four times higher than carbon steel, stainless ratio 10 times higher. Self-lubricating, low friction, non-sticking, high impact strength, the temperature of -196 degrees Celsius in liquid nitrogen can maintain excellent performance, is the best known engineering plastics. In addition to a handful of its corrosive solvent, the common inorganic and organic acids, alkalis, salts and organic solvents such materials are not corrosive. You can also do the food pipe valves, sanitary, non-toxic, safe and in line with the Japanese health standards, and has been approved by the US Food and Drug Administration and the US agricultural sector. Meet the water quality fluids, solids, powders, slurries and other media environment. Traditional metal is difficult to meet the requirements of super molecular weight polyethylene can be an alternative, because of its high wear resistance, corrosion resistance, overall performance self-lubricating, and absorb shock in the industry has a wide range of applications. Tailings pipeline tailings pipeline refers to non-ferrous metals and ferrous metal mineral beneficiation tailings slurry discharged, to be transported to the tailings stock put, the current mainstream approach is to use domestic transport tailings pipe conveyor. The main characteristics of the tailings pipe is used in ultra high molecular weight polyethylene pipe. Ultra high molecular weight polyethylene pipe (UHMWPE) refers to the viscosity-average molecular weight of more than 1.5 million linear structure of polyethylene (PE), due to its high molecular weight, resistant to abrasion, impact resistance, corrosion resistance, self-lubricating excellent overall performance, called "amazing plastic", but more difficult molding. In recent years, due to the plunger is pushed, a single screw extruder and other breakthrough technologies, so UHMWPE pipe to achieve the industrial continuous production. UHMWPE tailings pipeline has the following advantages: (1) Wear Habitat plastic crown, carbon steel, stainless steel, 7 to 10 times; (2) the impact strength of plastic in the first column, 2 times for the PC, 5 times the ABS, and can keep at liquid nitrogen temperature (-196 ℃); (3) self-lubricating, anti-adhesion, non-fouling, low coefficient of friction, with polytetrafluoroethylene (PTEE) comparable; (4 ) impact energy absorption values ??in the highest of all plastics, and possessed silencers; good (5) chemical stability, within a certain range of temperature and concentration ability of various corrosive media and organic media; (6) excellent low temperature resistance, remain at liquid helium temperature (-269 ℃) ductility; (7) excellent resistance to compressive strength, resistance to environmental stress cracking resistance, resistance to rapid crack resistance; (8) health, non-toxic, food contact and drugs.
