摘要
为确保新型载体炸药DNAN熔铸装药过程的安全性,着重从炸药的基本特性和装药工艺流程等方面对熔铸装药工艺进行安全分析,并采用自行设计的一种烤燃试验装置,对DNAN的热安全性进行试验研究,得到其在不同温度下的热爆炸延滞期。结果表明:DNAN在220℃环境温度下,放置48 h没有发生反应;230℃发生不完全燃烧;当温度达到240℃以上时发生热分解反应;理论计算DNAN在通常的熔药温度(100℃)下的热爆炸延滞期,表明DNAN的装药工艺安全可靠。
In order to ensure safety in melt-cast process for the DNAN explosive, emphasize safety analysis from the explosive properties, the melt-cast technological procedure, the thermal safety of DNAN explosive was studied by cook-off test, the delay time of thermal explosion in different temperature was obtained. The results show that DNAN under the ambient temperature of 220℃ was non-flammabled, DNAN was semi-burned under the ambient temperature of 230℃, when the temperature reaches above 240℃, thermal decomposition reaction of DNAN occurs. The delay of thermal explosion was obtained from theoretical calculation at 100℃, results show that the DNAN explosive melt-cast technological is safe and reliable.
