摘要
用硫酸分解开阳磷矿 ,研究了活化疏松剂 (APA)对该反应过程的影响。结果表明 ,活化疏松剂的加入对酸解磷矿过程中的固膜内扩散过程有影响 ,最终结果能提高磷矿的转化率 ,缩短熟化期 ,改善产品物性。
The effect of activation porous agent on reaction process of phosphate rock acidulated by sulfuric acid was studied. The results indicated that APA could affect the process in which the hydrogen ions diffused through the calcium sulfate layer coating on the phosphate rock, improve the rate of conversion of superphosphate, shorten its curing time and reform its physical appearance.
