PVC塑料是一种多组分的塑料，根据不同用途可以加入不同的添加剂，PVC材料在实际使用中经常加入 稳定剂、 润滑剂、钙粉填充料、 色料、抗冲击剂及其它添加剂。因此随着组成的不同，其制品可呈现不同物理机械性能，如加入钙粉填充料时候机械阻力加大，PVC塑料制品挤出模头时候会造成表面摩擦加大，影响PVC制品光亮度，通过添加PVC塑料光亮剂可以减小机械阻力，延长挤出机螺杆的寿命，还能有效增加内润滑减小制品挤出模头的摩擦力，使制品表面平整光滑，亮度备增。 PVC plastic is a multicomponent plastic, according to different uses can add different additives, PVC materials in actual use, often adding stabilizer, lubricant, calcium powder filler, pigment, impact resistant agent and other additives. So with the different composition, their products may exhibit different physical and mechanical properties, such as adding calcium powder filler when the mechanical resistance increased, PVC plastic extrusion die when the surface can cause increased friction, effect of PVC product brightness, by adding a PVC plastic brightener can reduce mechanical resistance, prolong the service life of the screw extruder. The friction force can effectively increase lubrication to reduce the product extrusion die, make the product surface smooth, brightness increase.
