摘要
湿法磷酸生产中添加表面活性剂可以有效地改善磷石膏结晶,减少磷石膏中P2O5损失,提高过滤性能。本文研究了一些表面活性剂在此方面的一些作用影响。
The addition of some surfactants in the wet-process phosphoric acid producing could greatly improve the crystallization of the gypsum, reduced the intercrystalline P205 losses and improved the filtering perfor- mance. The roles and impacts of some kinds of surfactants in this regard were studied in this paper.
