我国漂粉精产品市场及生产技术概述

Summary on market and production technology of bleaching powder concentrate at home

介绍了我国漂粉精产品生产和市场发展情况 ,着重分析了钙法和钠法漂粉精生产技术要点 ,并对我国引进的两种钠法漂粉精工艺进行了比较 ,指出Chemetics工艺比DeNora工艺更能保证有效氯含量在 70 %以上 ,DeNora工艺产品适用于需快速溶解的使用场合 ,而Chemetics工艺产品则适用于溶解速度要慢一些的场合。

Development situation of market and production technology of bleaching powder concentrate at home is introduced.The key technologies in its production both by calcium-method and sodium-method are analyzed emphatically.Two kinds of sodium-method processes imported from abroad are compared.It is found that it is even more assured by Chemetics process than by DeNora process that available chlorine content in product is above 70%,and the DeNora product is suitable for situations that quickly soluting are needed while the Chemetics product is suitable for situations that slow lier soluting are needed
