摘　　要：从复合肥料中各种盐类之间的化学反应角度分析复合肥料结块的机理,研究了复合肥料中盐类的最基本反应,即硫酸铵、磷酸二铵和氯化钾之间的反应,以及硝酸盐类复合肥料的主要构成盐类,认为复合肥中各种盐类之间的化学反应是贮存中结块的主要因素,从而提出生产控制及贮存中避免结块的根本方法是防止产生盐类间的化学反应,而加入防结块剂应为辅助手段。By the analysis on the chemical reactions of various salts in compound fertilizer for the caking mechanism of compound fertilizer, the basic salt reactions among ammonium sulfate, diammonium phosphate and potassium chloride as well as the main salt components of nitrate-based compound fertilizer are studied. The chemical reaction of various salts in compound fertilizer is considered the main factor for compound fertilizer caking in storage, so the chemical reactions of various salts should be avoided in compound fertilizer production and storage, with adding anti-caking agent to compound fertilizer as the assistant method.
