【摘要】 耐热炸药热安定性在其应用中具有重要作用。本文采用差示扫描量热(DSC)、热重(TG)、真空安定性(VST)等热分析方法,研究了TATB、PYX和LLM-105的热安定性,对TATB、PYX和LLM-105的热分解表观活化能进行了计算。实验结果表明:TATB、PYX和LLM-105在较宽的温度范围内具有较高的热稳定性,耐热温度都超过250oC。这3种炸药的热安定性顺序为:PYX略优于TATB,TATB优于LLM-105。更多还原

【Abstract】 The thermal stability of heat-resistance explosives plays an important role in their applications. The thermal stability of TATB, PYX and LLM-105 was investigated using DSC, TG and VST thermal analysis methods, and the decomposition activation energy was calculated. Experimental results show that TATB, PYX and LLM-105 are stable in a wide temperature range, and their heat-resistance temperatures are all over 250oC. The heat-resistance order for the three explosives is: PYX>TATB>LLM-105.更多还原
