硝基复合肥生产中经常出现产品结块的现象,而使产品的使用性降低。研究部分不同pH的原材料如磷酸一铵、硫酸钾在特定环境下对硝基复合肥产品结块的影响。结果表明,随着pH的降低,产品结块率有升高趋势;采用碱性原材料如磷酸氢二钾和磷酸氢二铵中和产品,调节pH,可有效降低产品结块率。 Nitrogen compound fertilizer often appear in the production of product caking phenomenon, leaving the product of reduced use. The effect of some raw materials with different pH such as monoammonium phosphate and potassium sulfate on agglomeration of nitro compound fertilizer products under certain environment was studied. The results showed that with the decrease of pH, the agglomeration rate of products increased. Alkaline raw materials such as potassium phosphate dibasic and diammonium hydrogen phosphate were used to neutralize the products to adjust the pH, which could effectively reduce the product caking rate.
