硬质粘土生产聚合氯化铝工艺的改进

An Improvement on Process of Producing Poly-aluminium Chloride from Refractory Clay

用硬质粘土生产聚合氯化铝，在聚合反应中，采用了ＣａＣＯ３与ＣａＯ的混合中和剂。利用ＣａＣＯ３中和溶液中的Ｈ＋离子产生的ＣＯ２气体，将ＣａＯ分散，使ＣａＯ反应完全，以利于产品的质量控制。

Poly-aluminium chloride was produced from refractory clay. The mixture of CaCO3 and CaO was used as neutralizing agent during polymerization. CO2, yielded by neutralizing H+ cation in solution with CaCO3, dispersed CaO, which made its reaction thoroughly and controlled the product with better quality.
