两种硝铵炸药的绝热分解研究

Study on Adiabatic Decomposition of Expanded AN-diesel Oil Explosive and Expanded AN-trinitrotoluene-diesel Oil Explosive

用加速量热仪(ARC)对膨化铵油炸药和膨化铵梯油炸药进行了绝热安定性测试,通过数据校正和分析,发现膨化铵油炸药在加入TNT之后安定性下降,诱导时间大大缩短,而放热量却大大增加,爆炸能量和威力也显著增加。最后用速率常数法计算了两种硝铵炸药的活化能E和指前因子A。

The adiabatic stability of expanded ANdiesel oil explosives and expanded ANtrinitrotoluenediesel oil explosives were tested by Accelerating Rate Calorimeter (ARC). According to the ARC data, a conclusion was drawn that after adding TNT to the expanded ANdiesel oil explosive, its stability decreased and the induction time reduced greatly, while the exothermic heat increased greatly, and the blasting energy and power also increased sharply. Finally, the activation energy E and frequency factor A were calculated by the velocity constant method.
