摘要: 全面地介绍了常用聚氯乙烯(PVC)树脂的物理、物化及加工性能指标,指标中不仅包括国标GB/T5761—2006中所列出的黏数(K值或平均相对分子质量)、杂质粒子数、挥发物、表观密度、筛余物、“鱼眼”数、100 g树脂增塑剂吸收量、白度、水萃取物电导率、残留氯乙烯单体含量等指标,同时还有热稳定时间、相对分子质量分布、平均粒径、原始白度、流变性、堆积密度和粉体干流性等非国标性能指标。通过这些分析和介绍,可以使读者对PVC树脂各项性能指标的特点和作用有更深刻地认识,便于通过性能指标来选择合适的PVC树脂,制定出更优的配方和工艺,对PVC加工具有很好的指导作用。

Abstract: This text introduced various meaning and the function of index signs of the PVC resin completely, not only include the GB/T5761—2006 in the index sign in 10 index signs list, such as: Viscosity Number (K value or Polymerization Degree ); Impurity Granule Number; Volatile Matter; Bulk Density; Course Particles; “Fish Eyes” Number; 100g resins Plasticizer Absorption; Whiteness; Determination of Conductivity of Water Extraction ; VCM Content. Still have the other the index sign outside the Chinese national PVC resin standard, include: Thermal Stability, Molecular Weight Distribute, A path, the Initial White Degree, Meltdown Liquidity, the Density of the Extrusion and Powder Body Liquidity etc. Pass by the analysis and the introduction, we can deepen our understanding the characteristics and the functions of the PVC resin index. It is easier to select the PVC resin by index. It will help to use the PVC resin better than before.
