PVC转化脱酸技术的应用及改进

Application of depickling technology in PVC conversion and its innovation

介绍了对聚氯乙烯转化脱酸工艺的应用及改进,通过改变塔板数、开孔率及对工艺、设备防腐形式的选择优化,已取得较成熟的经验,具有一定的借鉴性。

Application of depickling technology in PVC conversion and its innovation were intro-duced. After the change of column plate number and opening rate, and optimization selection of process and anticorrosive type of the units, ripe experiences were received. There was much in the process that we could make use of.
