The visual ultrahigh molecular weight continuous extrusion experimental device for polyethylene has the advantages of novel structure, simplicity in process, low in cost, convenience in use and the like, and integrates economy and practicality.

Description

technical field [0001] The visible ultra-high molecular weight polyethylene continuous extrusion experimental device of the invention relates to an experimental device for producing ultra-high molecular weight polyethylene profiles by using a continuous extrusion process. Background technique [0002] Ultra-high molecular weight polyethylene is non-toxic, tasteless, and hygienic. It is called "amazing plastic". Its aging life can reach more than 50 years under natural light. It is the best alternative pig iron in the world. and carbon steel plastic. However, due to the high molecular weight, "excellent performance, difficult processing" has become a world-recognized problem. The existing UHMWPE profile manufacturing processes include molding method, plunger extrusion method, screw extrusion method and some special methods, but it is very difficult to process UHMWPE with a molecular mass greater than 10 million, without any Additives, the production efficiency is very low, ...
