摘要
目前丝光处理棉产生的淡烧碱(约8°Be'＝5.2%,2~11m^3/h NaoH)通常都进行回收,但此循环过程造成碱液中的杂质积累.本文介绍了用双氧水净化浓缩的回收碱液的重要意义和处理方法.
Today in the whole world weak caustic soda (2 to 11 m3/h NaOH, approx. 8°Be' = 5.2%) resulting from the treatment of cotton in the mercerising process is usually recovered. Because of this recycling process the impurities increases in the lye. Lye with H2O2 to treat the starch sizes and other components retains its importance.
