【Abstract】 The variabilities of lubrication of plastic lubricants were analyzed as well as the diversities of plastic processing equipment.The importances of plastication rate and the melt viscosity for the processing of plastics,especially the processing of decomposable PVC,were described in detail.It was proposed that the plastication time and plastication torque on torque-time curves were the experimental basis for the formula design of plastic lubricants for PVC(i.e.internal and external lubrication balancing laws).更多还原
