The chain guide has ultra-high molecular weight, and the molecular weight is usually more than 1.5 million polyethylene varieties. Has excellent impact resistance and self-lubricating properties. It almost concentrates the advantages of various plastics, and has the unparalleled wear resistance, impact resistance, self-lubrication, corrosion resistance, impact energy absorption, low temperature resistance, hygienic non-toxicity, non-adhesion, and non-adherence of ordinary polyethylene and other engineering plastics. Comprehensive properties such as water absorption and low density. In fact, there is no simple polymer material with so many excellent properties. What is the processing technology of the chain guide rail? Because the viscosity of ultra-high molecular weight polyethylene (UHMW-PE) in the molten state is as high as 108Pas, the fluidity is extremely poor, and its melt index is almost zero, so it is difficult to use general machining. method for processing. In recent years, the processing technology of ultra-high molecular weight polyethylene (UHMW-PE) has developed rapidly. Through the transformation of ordinary processing equipment, ultra-high molecular weight polyethylene (UHMW-PE) has been developed from the initial pressing-sintering molding to Extrusion, blow and injection molding and other special methods of molding.
Features of high-precision ultra-high chain guide rails: 1: Small wear. 2: Small friction resistance. 3. Self-lubricating. 4: Has impact resistance. 5: Operating temperature range -200 plus 280 degree . 6: It has a shock absorption effect. 7: It is not easy to be affected by moisture in a humid environment. 8: It has high chemical resistance. 9: Corrosion resistance. The main features of the chain guide rail are high self-lubrication, no water absorption - destruction of molecular chains formed by water absorption, elimination of adhesion, and natural and smooth cutting. High wear resistance and impact resistance are added with a variety of modifiers to maintain the original characteristics and improve the more practical advantages. Impact resistance---The impact resistance reaches 150KJ/㎡ without breaking. Excellent environmental stress cracking performance, 200 times that of ordinary polyethylene. Excellent low temperature resistance, no embrittlement even at 176 degree .
