Application Of Ultra High Molecular Weight Polyethylene Liner In Low Temperature Environment
In general, we apply ultra-high molecular weight polyethylene sheet in some food filling industries. One of the more important reasons is that the material has good physical and mechanical properties, and it is non-toxic, tasteless and non-absorbent. , no bonding, corrosion resistance, light weight and many other advantages. We all know that the composition of the ultra high molecular weight polyethylene liner is ultra high molecular weight polyethylene.
Since the material is a high viscosity polymer, it is generally in the form of a powder, and its typical particle size ranges from 100 to 200 microns. Such a polymer structure allows the ultrahigh molecular weight polyethylene sheet to maintain excellent mechanical properties even under low temperature conditions. The ultra-high molecular weight polyethylene liner is prepared by high-pressure molding process after melting various kinds of ultra-high molecular polyethylene raw materials and inorganic additives at a high temperature.
Due to the high viscosity of the material of its own composition, the ultra-high molecular weight polyethylene liner can not be used in the molding process, and it is generally not necessary to use ordinary thermoplastic molding methods. Generally, it is usually used in a molding or plunger extrusion process to super-high pressure. The high molecular weight polyethylene particles are melted and sintered into a billet or profile and, if necessary, subsequently machined.
We know that the production of each product has its own application, otherwise it will not be further developed and applied. For the ultra-high molecular weight polyethylene liner we are talking about today, it can be produced. Do all kinds of mechanical parts, including food machinery gears, worm gears, worms, bearings; chemical industry: do pumps, valves, baffles, filter plates.
