Ultra-high-molecular-weight polyethylene refers to linear polyethylene with an average molecular weight of 1.5 million or more. It has abrasion resistance that is unmatched by other general-purpose plastics and engineering plastics (the first place in plastics is 4 times higher than nylon, and is carbon steel. , 7 to 10 times that of stainless steel, impact resistance (first in plastics, 5 times that of ABS, 2 times that of polycarbonate), corrosion resistance, low temperature resistance, self-lubricating, shock absorbing energy, hygienic non-toxic, etc. It is called "amazing plastic". Due to the extremely high melt viscosity of the material (almost no flowability), domestic and foreign companies have mainly used press-sintering methods to produce plates and some simple parts for a long time, and the production efficiency is extremely low. Nowadays, a new technology for production has been successfully developed. It adopts a specially designed injection molding machine and a reasonable molding process and formula to produce round, sleeve-shaped and other irregularly shaped complex products. High-molecular-weight polyethylene is a multi-variety, large-scale industrial production. The technical process of this technology is to directly mix the raw material with a small amount of additives, and then directly join the injection molding machine for injection molding without granulation. The product cost is low, and white color products can be obtained. The product has good shape and dimensional stability and excellent physical and mechanical properties. The equipment is highly automated and easy to operate. Compared with the traditional press-sintering method, the production efficiency can be increased by more than 50 times. The finished product can be used as impact, wear, corrosion and low temperature parts. Such as: textile knots and shuttles, stepping rod rotors, water metering tips, filling line support rollers, pump impellers, axial-flow pump water-lubricated shaft sleeves, and refrigerator parts. Excellent value for money, can replace expensive copper, stainless steel, PTFE, nylon, polyoxymethylene, polycarbonate and other materials. Major media and medical research continue to remind people that a sedentary lifestyle is closely related to many health risks, such as back or neck pain, high blood pressure, heart disease, and obesity.
