摘要:
采用差示扫描量热仪（DSC）、加速度量热仪（ARC）和改进的通风管试验（MVPT），考察了尺度效应对硝酸铵热分解特性的影响。硝酸铵在DSC试验中的初始热分解温度为277.45 ℃，在ARC试验中的初始热分解温度为245.62 ℃，且在245.62～261.16 ℃之间，反应系统压力持续升高。在MVPT试验中，硝酸铵在120 ℃左右就会发生显著热分解，在250 ℃左右会发生剧烈反应。结果表明，尺度效应对硝酸铵热分解特性具有显著影响。
Abstract:
Differential scanning calorimeter (DSC), accelerating rate calorimeter (ARC) and modified vent pipe test (MVPT) were used to study the influence of scale effect on thermal decomposition characteristic of ammonium nitrate (AN). In DSC test, the decomposition onset temperature of AN was 277.45 ℃. While in ARC, it started at 245.62 ℃, and the pressure continued to rise until 261.16 ℃. In MVPT test, a significant thermal decomposition occurred at near 120 ℃, and reacted violently at 250 ℃. Test results indicate that the scale effect influences the thermal decomposition of AN significantly.
