摘要
把聚丙烯腈“废丝”水解的两段工艺过程即碱性水解→中和,改为碱性水解→沉胶提碱→中和三段工艺过程后,不仅减少了生产过程中盐和碱的消耗量,而且中和产品的含盐量可以减少十分之九,更有利于油田堵水及其它方面的应用。文中对三段水解工艺过程中的各种影响因素进行了讨论。
The three section hybrolization technique(alkaline hydrolization settling glue and extracting alkali neutralization) for the waste polyacrylonitrile filament is developed. Compared to the two section hydrolization technique (alkaline hydrolization, neutralization), this technique not anly decreased the consumptive acid and alkal quantity of the process, but also decreased the salt content of hydrolyzate by 90%, and the hydrolyzate is more suited for the application of oil field blocking water and other fields. The influential factors of the threesection hydrolzatoin technique are disussed.
