Plastic profile extrusion die is a core part of the extrusion of plastic profile extrusion die technology status is directly related to the stability of extrusion, and extrusion quality products, extrusion production efficiency and service life of the mold itself. Therefore, plastic profile extrusion die proper use and maintenance is very important. Plastic profile extrusion die checking the box to check the box after the arrival, the packaging is intact: Remove the packing list of technical documents, manual plastic pvc profiles manufacturers out of the box, according to an inventory of the contents of the packing list for the formation of the whole mold , accessories, special tools. Plastic profile products use more: window frames, stair handrails, trunking, skirting boards, shaped and so on. The main raw material is hard PVC, few are semi-rigid PVC, soft PVC, polyurethane foam and other materials low. PVC polymer is amorphous, no sharp melting point plastic pvc profiles, heated to 120 ~ 150 ℃ having plasticity. Because of its poor thermal stability plastics pvc profiles supply, at the same temperature containing a small amount of HCl released to promote further decomposition, it must be added to the alkaline stabilizer and HCl and inhibit its catalytic cracking reactions. Pure PVC is hard products, the need to add the right amount of plasticizer to make it soft for different products need to join, such as UV absorbers, fillers, lubricants, pigments, preservatives and other additives in order to attain good PVC products performance. And other like plastics, resin properties determine product quality and processing conditions. PVC plastic in terms of pvc profile, and processing properties related resins are: particle size, thermal stability, molecular weight, fish eyes, bulk density, purity and foreign matter, porosity. There paste for PVC paste viscosity and gelling properties, should be determined to try, easy to grasp the processing conditions and product quality.
