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

Product characteristics : 1, excellent heat resistance : can adapt to the use of power lines due process overload and short circuit of the high temperature; 2, excellent electrical properties : material for the performance of their higher intensity and volume resistivity of insulation, security is good; 3. excellent corrosion resistance and anti-aging properties : apply to the soil and working environment, long life; 4. excellent flame retardance : difficult combustion; 5, smooth wall formation, the friction coefficient, good wear resistance : in the installation process can greatly reduce the damage to power lines, improve work efficiency; with the traditional asbestos cement pipes, the The product is light weight, good flexibility, earthquake-resistant and differential settlement, and not at the construction site encapsulation pouring concrete; Transport construction is simple, low cost, can greatly shorten the construction period.
