摘　　要：分析磷酸二铵的结块机理,从结块的主要影响因素(温度、湿度、粒度等)进行优化,初探利用粉煤灰合成沸石粉作其防结块剂的可行性研究,实验证明,沸石防结块剂在磷酸二铵的结块中有显著效果。By analysing the caking mechanism of diammonium phosphate,the experiment is aimed to optimize the influential factors of casing including temperature,moisture and granularity etc.in order to research the feasibility of compounding zeolite powder with flyash as anti-caking agent.The result demonstrates that the zeolite anti-caking agent has conspicuous inhibitional effect on the caking of diammonium phosphate.
