摘要
自制炸药的热安定性在实际应用中具有重要作用。选择三种典型自制炸药配方(硝酸铵+铝粉、氯酸钾+碳粉、高锰酸钾+硫),并对其进行不同升温速率下的DSC差热分析,标定了三种自制炸药的活化能与指前因子等热动力学参数。利用有限元程序Fluent对三种自制炸药配方的简易爆炸装置在不同温度环境中的热响应规律进行了数值计算。实验和数值计算结果表明:三种自制炸药在较宽的温度范围内具有较高的热稳定性;三种炸药的热安定性顺序为:氯酸钾+碳粉、高锰酸钾+硫和硝酸铵+铝粉。
The thermal stability of home-made explosive plays an important role in practical application. Three typical home-made explosive formulations(NH_4NO_3+Al, KClO_3+C, KMnO_4+S) were selected for DSC experiment. The thermal kinetic parameters including activity energy and pre-exponential factor were determined on the basis of DSC experiments. The thermal responses of the three home-made explosive formulations in improvised explosive device at the different temperature environment were calculated by the finite element program Fluent. The experiment and simulation results show: the three home-made explosives are stable in a relative wide etmperature rang; the heat-resistance order for the three explosives is: KClO_3+C> KMnO_4+S> NH_4NO_3+Al.
