摘要
以钛白生产副产物硫酸亚铁为原料,碳酸铵为沉淀剂,通过空气氧化制备超细氧化铁颜料。采用表面活性剂使颜料粒子分散,并在一定温度下处理产品。所得氧化铁粒子均匀,有光泽,平均粒径在100nm以下。这种方法较以前的一些生产工艺简便、经济,并解决了污染问题。
A sup rfine iron oxide pigment has been pre-pared by using the ferrous sulfate, a by-prod-uct of TiO_2 production, as raw material, am-monium carbonate as precipitating agentthrough air oxidation.The pigment was dis-persed with a surfactant and treated at a certaintemperature.The produet obtained has uniformparticle size and average particle size 100 nmwith gloss.The new developed process is moresimple and economic in production and solvesthe environment pollution problem.
