What Are The Specific Maintenance Tasks For Polythene Liners?

　Many users ask us how they should do a good job of maintaining the polyethylene linerboard.

　　Polyethylene liner plate moulding temperature has a great impact on the quality of products, attention should be paid to control the temperature of the middle of the mould is slightly lower than the temperature of the two ends, there should be a uniform and stable temperature conditions to assist, mould lip spacing is equal to or slightly less than the thickness of the ultra-high molecular weight polyethylene sheet, uniform and stable temperature to ensure that the flow rate of extruded molten material volume of flow rate smooth isobaric pressure, so that the plate's longitudinal thickness of the error value of the plate is small. The temperature control of the forming mould should be stable, too high or low temperature should affect the flow rate of the melt, so that the thickness error of the formed UHMWPE sheet will be bigger. At higher temperature, the melt is easy to decompose and there will be bubbles in the sheet, and the surface of the sheet is dark and not smooth when the temperature is low.
