摘要
简述了PVC树脂生产原料的工艺指标及分散剂在VCM聚合中的作用,调整了采用70 m3聚合釜生产PVC树脂的工艺配方,并对生产出的PVC树脂产品质量进行了检测.结果表明：PVC树脂颗粒形态规整,内部结构疏松,表观密度为0.53 ～0.54 g/mL,黏数为112～114 mL/g,100 g PVC树脂增塑剂吸收量为23 ～25 g,“鱼眼”数小于10个.
The process indexes of raw materials for as the roles of dispersing agents in VCM polymerization. in 70 m3 polymerizers were adjusted and the qualities of showed that the obtained PVC resins had regular particle density 0.53 -0.54 g/mL, viscosity number 112 -114 PVC）, and fisheye number less than ten. production of PVC resins were described as well The process formula for PVC resin production obtained PVC resins were measured. The results shape and loose internal structure, with apparent mL/g, oil absorption 23 -25 g（based on 100 g
