摘要
对常用于PVC-U异型材生产的PVC-SG5树脂进行了指标分析,认为影响PVC塑化性能的重要指标为K值、粒径、分子质量分布、表观密度、孔隙率以及PVC树脂颗粒聚集和表面形态。
The indexes of PVC - SG5 resin commonly used for the manufacture of PVC - U profiled section materials are analyzed. The indexes considered to be important to PVC plastic properties include K value, molecular weight distribution, apparent density, porosity, and the aggregation and surface morphology of PVC resin particles.
