激光衍射光散射法在聚氯乙烯树脂粒度分析中的应用

The application of laser diffraction light scattering technique on particle size analysis of PVC resin

主要介绍激光衍射光散射法在聚氯乙烯树脂粒度分析中的应用。并与筛分法对照 ,比较了两种方法测得样品的平均粒径、分布宽度、三目集中率 。

This paper mainly introduces the application of laser diffraction light sca- ttering technique on particle size analysis of PVC resin and this technique is compared with sieve method.The sample's average particle-size,distribution width and three-meshes centralized percentage determined by above two methods are compared.The relation between particle morphology and processability is also discussed.
