摘要
用红外光谱分析、X-射线衍射分析表征了不同聚磷酸铵(APP)的结构,对APP进行了热分析和粒度分析。用特殊方法制备的低水溶解度的APP在水中的溶解度(20℃)由原来的 8. 6×10-3 g/g降为 1. 17×10-3g/g,接近于Exolit422APP的溶解度 1. 2×10-3 g/g。
The structure of different ammonium polyphosphate(APP) is characterized by IR,XRD.The thermal behavior and particle size of APP are analysed.The water solubility(20 ℃)of the APP prepared by special method is lowed from (8.6×10^(-3)g/g) to 1.17×( 10^(-3)g/g,),which is near to 1.2×10^(-3) g/g of Exolit 422 APP made in the U.S..
