UHMWPE extruded Lubrication: Lubrication extrusion (injection) molding technique is extrusion (injection) forming a lubricating layer between the material and the die wall, thereby reducing the shear rate of the material differences between the points wear coal bin liner factory, reducing the deformation of the product, while the high viscosity of the polymer can be improved extrusion (injection) at low speed, low-power condition. The method produces a lubricating layer of mainly two: self-lubricating and co-lubrication. Self-lubricating UHMWPE extruded: external lubricant mainly higher fatty acids, complex lipids, silicone resin, paraffin and other low molecular weight resins. Prior to extrusion (injection) process, first lubricant processing aid is mixed together with other materials in buying coal bunker liner wear, wear-resistant coal bin liner price production, lubricant leaking material to form a lubricating layer to achieve self-lubricating extrusion (injection).
