摘要
阐述了聚氯乙烯聚合工艺原理,包括助剂配制(引发剂、分散剂、涂壁剂、碱液、终止剂及链转移剂)、聚合、浆料汽提、废水汽提、VCM回收、公用工程系统设置等。并说明了装置聚合釜的设备安装和管道布置。
This paper expounded the principle of PVC polymerization process,including sections like additives preparation(initiator,dispersant,wall coating agent,alkali solution,termination agent and chain-transferring agent),polymerization,slurry stripping,waster water stripping,VCM recovery,and utilities system setup.It also explained the polymerizer ' s equipment installation and pipeline layout.
