鸡蛋壳制取硫酸钙生产工艺研究

Study on the Production Technology of Calcium Sulfate (CaSO_4) Made from Shells of Eggs

本文报导了以废物鸡蛋为原料用盐酸浸溶，然后加硫酸制取硫酸钙的方法，采用Ｌ９（３＾４）正交实验获得了从鸡蛋壳制取硫酸钙的最佳条件，其工艺简单，产品质量稳定，为废物的综合利用开辟了一条新途径。

Using waste egg shells as raw materials,hydrochloric acid(HC1) soaking and sulfuric acid(H2SO4) adding,the calcium slfate' s product technique is reported. The optimun technique conditions are obtained by L4(3+) orthogonal test method. The making technique is simple,and the product quality stable,Here is a new way of utilizing waste materials.
