为了解超细六硝基艹氐(HN S)的热分解性能,通过DSC-TG实验研究HN S-Ⅳ的热分解过程,用K iss inger法和O zaw a法计算了HN S-Ⅳ热分解反应动力学参数。结果表明,HN S-Ⅳ的热稳定性与HN S-Ⅱ相当。K iss inger法和O zaw a法得到的HN S-Ⅳ分解表观活化能分别为221.4 kJ/m o l和220.3 kJ/m o l,比静态气氛下HN S-Ⅱ热分解反应的表观活化能减小27 kJ/m o l。
In order to understand the thermal decomposition of HN S, the thermal decomposition of HN S-Ⅳ was studied by DSC-TG and the HN S-IV was calculated by K iss inger method and Ozawa method Decomposition reaction kinetics parameters. The results show that the thermal stability of HN S-Ⅳ is comparable to that of HN S-II. The apparent activation energies of decomposition of HN S-Ⅳ obtained by K iss inger method and O zaw a method were 221.4 kJ / mol and 220.3 kJ / mol, respectively, which were lower than that of HN S-Ⅱ pyrolysis reaction under static atmosphere 27 kJ / mol.
