UHMWPE forming: the viscosity of the ultrahigh molecular weight polyethylene (UHMW-PE) in a molten state up to 108Pa * s polyethylene liner wear rates, poor flowability, melt index is almost zero, it is difficult by conventional machining methods for processing. Ultra high molecular weight polyethylene (UHMW-PE) of processing technology has been rapid development of polymer polyethylene liner wear, through the transformation of ordinary processing equipment plant polymer polyethylene liner wear, has made the ultra-high molecular weight polyethylene (UHMW-PE) from the initial pressing - sintering the development of extrusion, blow molding and injection molding as well as other special methods. UHMWPE forming: pressing and sintering. Productivity is quite low, prone to oxidation and degradation. In order to improve production efficiency, can direct electrical heating method. Ultra-high-speed sintering machining method Usually polyethylene liner wear, using blade mixer, rotating blades can reach a maximum speed of 150m / s, so that the material can be raised only in a few seconds the processing temperature.
