在过磷酸钙生产中加入过磷酸钙专用松散剂(以烷基磺酸钠为主体的阴离子表面活性物),将其配成10%悬浊液以27mL/s的流量加入混合器1#、2#搅拌桨之间。通过加与不加松散剂的对比试验,发现加入松散剂熟化期由过去的10 d以上缩短为7 d,产品外观干松很多,但对产品有效磷含量、转化率影响不大。 In the production of superphosphate added superphosphate special loose agent (sodium alkyl sulfonate as the main anionic surfactant), which dubbed 10% suspension at a flow rate of 27mL / s added to the mixer # 1, 2 # between the stirring paddle. Through the comparison test with and without loose agent, it was found that the aging time of the loose agent added was shortened from above 10 days to 7 days, and the appearance of the product was very loose. However, it had little effect on the effective phosphorus content and the conversion rate of the product.
