一种DNAN基熔铸炸药压滤装药工艺安全性分析
|
摘要
为确保混合炸药在压滤装药工艺过程中的安全性,通过工艺过程安全性分析,获得了工艺安全性风险因素及其分类;利用试验测试和数值仿真手段,对一种DNAN基熔铸混合炸药(MCX-D)的本质安全性、相容性、机械和热刺激等装药工艺安全性影响因素进行了分析与研究。结果表明,炸药本质上是安全的,压滤工艺过程中组分变化和热损伤导致炸药本身感度的升高有限(机械感度≤40%),符合使用要求;装药在温度和压力双重作用下的内部温升仅为0.3℃左右,不存在热爆炸的可能性。由此证明DNAN基熔铸炸药压滤装药工艺是安全可靠的。
In order to ensure the safety of the filter press process of composite explosive,the risk factors and its classification of process safety were obtained according to analyzing the process engineering safety. By means of experimental test and numerical simulation,the influential factors including intrinsic safety,compatibility,mechanical and thermal stimuli of MCX-D,a kind of DNAN based melt-cast explosive,were analyzed and studied. It found out that the explosive made in the filter press process was safe intrinsically,and the sensitivity of explosive due to ingredient variation and thermal damage increased in a very limited range( improvement of mechanical sensitivity ≤ 40%),which met the application demands. The inner temperature increased by 0. 3℃ or so in the condition of temperature and press,which indicated the thermal explosion would not happen. The filter press process of DNAN based melt-cast was safe and reliable.
