Ultra-high molecular weight polyethylene liner itself has very prominent advantages, but we must do a good job in the maintenance of ultra-high molecular weight polyethylene liner in the process of application, so as to better its performance. Full display, thereby improving the effectiveness of our work.
Ultra-high molecular weight polyethylene sheet is an engineering plastic with relatively good comprehensive performance. Known as the "amazing material", the quality of the raw materials of UHMWPE determines the quality of the board products. So how much do you know about this maintenance work? Let's learn more about it:
First of all, the temperature of the ultra-high molecular weight polyethylene liner has a great influence on the quality of the product. It should be noted that the temperature in the middle of the mold should be controlled to be slightly lower than the temperature at both ends. There must be uniform and stable temperature conditions to assist; the distance between the die lips should be equal to or slightly smaller than the thickness of the ultra-high molecular weight polyethylene liner, and the uniform and stable temperature ensures that the flow rate of the extruded melt is stable and isobaric, so that the longitudinal thickness of the liner The error value is small.
