摘要
提出了以旧式沉淀碳酸钙生产装置,在不改变已有工艺的条件下,通过部分改变操作条件,添加少量结晶控制剂,并经表面活化处理,直接制取超细活性碳酸钙的方法。
A method is introduced of directly preparing extra-fine activated chalk by partly altering the operating conditions,adding some cystallizing agent and surface activation, with the precpitated chalk production unit without changing the present technology.It provides an efficient way to increase the additional value of the product.
