摘要
针对105 m~3聚合釜悬浮法PVC生产工艺,采用降低搅拌转速、调整引发剂配比、改变物料填充量及调整分散剂体系等工艺优化措施,使SG5型PVC树脂的颗粒形态改善,残留氯乙烯含量降低,表观密度提高。
In view of suspension method PVC production process in 105-m~3 polymerizer, some optimization measures such as reducing agitation speed, adjusting ratio of initiator, changing filling amount of materials and adjusting the dispersant system were taken,then the PVC-SG5 resin had improved particle morphology, reduced residual vinyl chloride content and increased apparent density.
