摘要
采用加速量热仪(ARC)研究了ε-HNIW的热稳定性,得到了ε-HNIW样品在绝热条件下热分解温度和压力随时间的变化曲线,以及自热速率、分解气体产物压力随温度的变化曲线,分析了在绝热条件下热分解反应动力学,计算了表观活化能E为256.28kJ/mol,指前因子为5.56×1025s-1。
The thermal stability of ε-HNIW was researched by an accelerating rate calorimeter. The curves of thermal decomposition temperature and pressure versus time, self-heating rate and pressure versus temperature were obtained. According to adiabatic theory, the activation energy E = 256.28kJ/mol and pre-exponenfial factor 5.56×10^25s^-1 were obtained.
