摘　　要：分析单质硫基磷铵生产的安全隐患.通过表面活性分散技术,实现了单质硫有效分散在磷铵中,生产中安全风险下降.经测算,生产w(S)4%的单质硫基磷铵1 t成本较生产磷酸二铵1 t降低2元.The hidden danger in the production of ammonium phosphate containing elemental sulfur is analyzed.The effective dispersion of elemental sulfur in ammonium phosphate is realized by surface active dispersion technology,and the safety risk in production is reduced.It is estimated that the cost of producing a ton of ammonium phosphate containing 4%elemental sulfur will be reduced by 2 RMB Yuan compared to diammonium phosphate.
