针对磷矿石中杂质含量多,导致过磷酸钙生产熟化期长、结块等问题,进行两种液体疏松剂(A与B)在过磷酸钙生产中的效果试验。结果表明,添加液体疏松剂比不添加的效果好;添加液体疏松剂B的过磷酸钙熟化期最短,30 d后半成品水分达标(w(H2O)14.5%),转化率高达79.75%,产品外观最好。
Aiming at the problems of more content of phosphate rock, such as long maturation period and agglomeration of superphosphate, the effects of two kinds of liquid osteoporosis agent (A and B) on the production of superphosphate were tested. The results showed that the addition of liquid loose agent was better than the non-added liquid additive; the liquid superplasticizer B had the shortest curing time of superphosphate, the water content of semi-finished product (w (H2O) 14.5%) after 30 d, the conversion rate was as high as 79.75% the best.
