摘要
采用自研的热爆炸试验装置对几种火炸药装药进行了热爆炸试验,获得了热爆炸临界温度和延滞期,通过试验和数据处理说明热爆炸试验及数据处理过程中应注意的几个问题。结果表明:对于加热过程中药柱形状变化的火炸药,须采用限制性全封闭体系;不同体系的热安全性评价需要结合热爆炸临界温度和延滞期来共同判断;延滞期与温度的倒数只在有限温度范围内成立。
The thermal explosion experiments of charging several explosives and propellants were carried out by using the self-developed thermal explosion experimental apparatus. The critical temperature and the delay period of the thermal explosion were obtained. The several notable problems during thermal explosion experiment process were explained through data processing. The results show that the limited and all-closed system must be used for the explosives and propellants with grain shape changing during heating process. The thermal safety evaluations for different systems need to be estimated by combining the critical temperature and delay period of the thermal explosion. The linear relationship between the delay period and reciprocal of temperature just exists in a limited temperature range.
