摘要:
为了研究改性后的硝基胍装药在生产、储存、运输和使用过程中因意外爆燃而产生的响应特性，采用温度采集仪记录了火灾刺激条件下硝基胍的火球温度变化规律，通过压力测试系统测量了反应过程的冲击波压力，使用热辐射测试系统测量了爆炸火球的热通量，通过Baker公式计算了火球的理论热通量。结果表明：第1发快烤点火后108 s样品发生反应，最高温度为894.3 ℃；第2发快烤点火后142 s样品发生反应，最高温度为960.7 ℃；两发快烤反应持续时间均约为2 s，响应等级均为爆燃。分析快烤响应过程中的冲击波、破片、热辐射毁伤效应发现，热辐射是硝基胍遭受火灾刺激的主要毁伤形式。对比两发快烤及不同距离处的热通量发现，测量值与理论值的规律一致。
Abstract:
In order to study the response characteristics of modified nitroguanidine charge due to accidental combustion and explosion in the process of production, storage, transportation and use, the temperature acquisition instrument was used to record the fireball temperature change law of nitroguanidine under fire stimulation, the shock wave pressure in the reaction process was measured by the pressure test system, the thermal radiation flux of explosive fireball was measured by the thermal radiation test system, and the theoretical heat flux of fireball was calculated by Baker formula. The results show that, 108 s after the ignition of No.1 fast cook-off test, the sample reacts, and the maximum temperature is 894.3 ℃; and 142 s after the ignition of No.2 fast cook-off test, the sample reacts, and the maximum temperature is 960.7 ℃. The duration of the two fast cook-off reaction is about 2 s, and the response grade is deflagration. By analyzing the damage effects of shock wave, fragment and thermal radiation in the response process of fast cook-off, it is found that thermal radiation is the main damage form of nitroguanidine stimulated by fire. Comparing the heat flux values in two fast cook-off tests and different distances, it is found that the measured value is consistent with the theoretical value.
