摘要
本文利用钛白粉生产过程的副产物硫酸亚铁作原料,经净化处理后,所得沉淀物再经热处理,即得到氧化铁颜料。该工艺简单可行,产品质量符合国标要求。既冶理了“三废”,解决了环境污染。
In this paper ,using ferrous sulfate (a by-product of titanium white) as raw material and sodium carbonate as precipitant, air as oxidative , the precipitate after being heat treatment,is right the ferric oxide pigment.This technology is simple,possible and the quality of the produce meets the national standard .It may not only solve the problem of environment pollution, but also increase the profit of enterprise .
