悬浮PVC 颗粒形态,既受聚合工艺条件的影响,又影响加工工艺,因而对它的研究从来为人们所重视.1 实验1.1 树脂制备树脂分别在16立升、70立升实验用聚合釜和7立方米生产用聚合釜中制备,分别采用偶氮二异丁睛一明胶体系生产紧密型树脂,和过氧化二碳酸二环已酯——纤维素醚类生产疏松型树脂.采集浑浊的树脂离心母液进行观察.
The suspension of PVC particles morphology, both by the polymerization process conditions, but also affect the processing technology, and thus its research has always been people’s attention.1 Experiments1.1 resin resin were prepared in 16 liters, 70 liters of experimental polymerization reactor and 7 Cubic meters of production polymerization reactor preparation, respectively, using azo bis-butyronitrile a gelatin production of compact resin, and peroxydicarboxylate - cellulose ether production of loose resin collection turbid resin centrifuge Mother liquor was observed.
