摘要
作为一种含磷氮的无机聚合物,聚磷酸铵正在逐渐进入复合肥和液体肥料的生产领域。介绍了聚磷酸铵的生产工艺和利用端基滴定法测定聚磷酸铵聚合度以及离子交换分离法测定聚磷酸铵聚合率的方法。
As an inorganic polymer containing phosphor and nitrogen,ammonium polyphosphate is gradually entering production fields of compound fertilizer and liquid fertilizer.This paper introduces the production process of ammonium polyphosphate,the way to measure polymerization degree of ammonium polyphosphate with end-group titration and polymerization rate of ammonium polyphosphate with ion exchange separation process.
