氯乙烯聚合体系中铁离子的来源及控制措施

Sources and control measures against iron ions in vinyI chloride polymerization system

分析了氯乙烯聚合体系中铁离子的来源,采取了相应措施,包括提高新鲜和回收氯乙烯单体质量、改进检修方式、增加除铁器、改变中和剂加入方式等。

The sources of iron ions in the vinyl chloride polymerization system were analyzed,and corresponding measures were taken,including improving the quality of fresh and recovered vinyl chloride monomers,improving maintenance methods,adding iron removers,and changing the addition method of neutralizers.
