What Should I Pay Attention To When Processing Ultra-high Molecular Weight Polyethylene Sheet?

Aug 01, 2019

Ultra-high molecular weight polyethylene sheet has been gradually recognized by the majority of users, we can see it in various industries, but this requires us to strictly produce and produce high-quality products, then ultra-high molecular weight polyethylene sheet What should be paid attention to during processing, and then we will explain in detail:

Firstly, the temperature of the ultra-high molecular weight polyethylene sheet has a great influence on the quality of the product. Note that the specific middle temperature of the mold should be slightly lower than the temperature at both ends. It should be assisted by uniform and stable temperature conditions; the lip spacing should be equal to or slightly less than the thickness of the ultra-high molecular weight polyethylene sheet, and the uniform and stable temperature ensures that the flow rate of the extruded melt is smoothly equal pressure, causing the longitudinal thickness error of the liner. The value is the smallest. Molding mold temperature control to stabilize the temperature too high or low will affect the flow rate of the melt, so that the thickness of the formed ultra-high molecular weight polyethylene sheet will produce a large error. At higher temperatures, the melt is easily decomposed and there are bubbles in the liner; when the temperature is low, the surface of the liner is dark and not smooth.

The main things to be aware of when processing ultra-high molecular weight polyethylene sheet are these. You must follow the instructions to carry out the correct operation, so that its performance can be fully displayed. If you still do not understand what you are doing, please feel free to We consult.
