结合原料和生产工艺,对粉状磷酸一铵产品的实际物相组成进行了计算和讨论,物相计算结果与产品实际物相吻合,并由此对产品中有效P2O5和水溶P2O5偏低的原因进行了分析、讨论,并提出了改进建议。
The actual phase composition of the powdery monoammonium phosphate was calculated and discussed based on the raw materials and the production process. The calculation results of the phase were in agreement with those of the actual product, and the reasons for the low effective P2O5 and water-soluble P2O5 in the product Analyzed and discussed, and put forward suggestions for improvement.
