在过磷酸钙生产中 ,磷矿品质、操作条件、游离酸含量、产品水分、环境湿度、产品堆压情况等诸多因素会导致过磷酸钙在包装成袋、堆压一定时间后 ,发生结块现象 ,给农民施用带来不便 ,而且其中的磷酸一钙转化为难溶性的磷酸铁、磷酸铝等 ,使有效磷降低。现已有不少厂家开发出多?
In the production of superphosphate, phosphate rock quality, operating conditions, free acid content, product moisture, humidity, product stack pressure and many other factors will lead to superphosphate packaged in bags, stacking a certain time, the occurrence of caking Phenomenon, inconvenience to the farmers, but also the conversion of calcium phosphate monohydrate into insoluble iron phosphate, aluminum phosphate and the like, which results in the reduction of available phosphorus. Now many manufacturers have developed more?
