聚氯乙烯离心母液水的回用改造

Modification in recycling of PVC centrifugal mother liquid

介绍了聚氯乙烯离心母液水处理的工艺改造措施以及运行过程中的经验,并对使用离心母液水入釜投料前后的聚氯乙烯树脂产品质量进行了对比。结果表明:离心母液水入釜后生产的PVC产品质量没有受到影响,并且还可产生经济效益约780.84万元/a。

The process modification measures for the treatment of PVC centrifugal mother liquid were introduced as well as the operation experience, and qualities of PVC products produced before and after the reuse of centrifugal mother liquid were compared. The results showed that the reuse of centrifugal mother liquid as raw materials didn ＇t influence the quality of obtained PVC product, and 7. 808 4 million RMB M economic effect could be acieved per year.
