查询词典 chlorid

PVA-2080 is one of the important dispersing agents to produce loose polyvinyl chlorid. At present KH-20 is mainly imported from Japan to take the place of the traditional gelatin to produce high quality PVC in our country. In order to solve this problem, we exploit PVA-2080 to replace the foreign products. The experiment includes two steps of polymerization and a process of partial alcohlysis. After a number of trials, we get a product of white particles.Its average degree of alcoholysis is 80.77% and t...

聚乙烯醇- 2 0 80 (PVA - 2 0 80 )是生产疏松型聚氯乙烯的重要分散剂之一目前，国内主要依靠进口日本的KH - 2 0以代替传统的明胶来生产高质量的PVC产品为了解决这一问题，作者开发了PVA - 2 0 80 ，以代替国外进口本试验经过两步聚合和部分醇解等过程，通过正交试验优化试验条件，得到了外观为白色粉末状颗粒、平均聚合度为 2 0 4 2、醇解度为 80 。77%的产品经小釜应用试验，效果比较理想
