Study on Properties of Filling Systems in Plastic Axial Vibration Injection Processing

摘要

Adding the axial oscillation into the polymer plastic processing is the dynamic processing of polymer.There are two sections,the axial shearing section and the axial extrusion section,in the effect of vibration on the melting.The experiments show that the composites in the axial shearing section have a smaller mean particle diameter and a narrower particle size distribution,compared to those in the absence of vibration.So the vibration on melting ameliorates the filled properties of polymer composite.The experiments of the High-density polyethylene and Calcium carbonate(HDPE/CaCO3)filling system prove that the analyses are right.
