摘要
针对二硝酰胺铵(ADN)的强吸湿性及吸湿性研究的迫切性,建立了动态分析的新方法。采用快速分析方法研究了ADN的吸湿性能,得出了ADN的吸湿过程曲线、临界相对湿度、吸湿速率曲线。比较动态分析方法与干燥器平衡法(标准方法GJB7708-2005-404.1)结果,认为两种方法准确度等效。动态分析方法的相对标准偏差为1.45%。
Aim at the strong hygroscopicity of ammonium dinitramid （ADN）and the necessity of the hygroscopicity investigation,a new dynamic analytical method was estabilished. The hygroscopicity of ADN was studied by a rapid analytical method. The curves describing the hygroscopic process, hygroscopic speed and critical relative humidity were obtained. Compared to airer equity method,the dynamic method showed an equivalent result to the standardization method GJB770B -2005 -404. 1 in accuracy. The relative standard deviation of the dynamic analytical method was 1.45%.
