根据Kooij公式和van′t Hoff公式,从恒速升温速率下的DSC曲线峰温导出了计算含能材料放热分解反应动力学参数的两个数学表达式,提出了计算相应动力学参数的数值方法。对1,3,5-三硝基-1,3,5-三氮杂环己酮-2(Keto-RDX),由导出的两个表达式、Kissinger法、Ozawa法、Tang法、Hu-Gao-Zhang法、非线性等转化率积分法(NL-INT)所得的活化能E值彼此接近,表明Kooij′s公式中的a值取0.5,van′t Hoff公式的b值取0.003,可得到合理的动力学参数。
According to the Kooij formula and the van’t Hoff formula, two mathematical expressions for calculating the kinetic parameters of the exothermic decomposition reaction of energetic materials are deduced from the peak temperature of the DSC curve at a constant rate of temperature rise. Numerical calculations of the corresponding kinetic parameters method. For the 1,3,5-trinitro-1,3,5-triazone-2 (Keto-RDX), two expressions derived from Kissinger, Ozawa, Tang, Hu- Gao-Zhang method, non-linear conversion rate integral method (NL-INT) obtained activation energy E values close to each other, that Kooij’s formula a value of 0.5, van’t Hoff formula b value of 0.003, Get a reasonable kinetic parameters.
