摘要
利用DSC研究了二级煤矿许用乳化炸药的热分解过程。用Kissinger法、Flynn-Wall-Ozawa法和非线性等转化率法计算了其表观活化能Ea和指前因子A。atava-est k法结果表明:该过程的反应机理归属为三维扩散(圆柱形对称),机理函数为Ginstling-Broushtein方程。二级煤矿许用乳化炸药的热分解特征温度与乳化炸药实际生产过程中的乳化温度、敏化温度及其使用温度的比较表明二级煤矿许用乳化炸药有良好的热安全性。
The thermal decomposition process of class 2 coal mine permissible emulsion explosive was studied by DSC. The kinetic parameters （the apparent activation energy and pre-exponential factor） of the process were calculated by the Kissinger method, Flynn-Wall-Ozawa method and integral isoconversional non-linear method. The results obtained by Satava-Sestak method indicate that the most probable mechanism function of the process is the Ginstling-Broushtein equation and the reaction mechanism is classified as 3D-diffusion reaction in column symmetry. The comparison of thermal decomposition characteristic temperature with the emulsion temperature and sensitizing temperature in actual production as well as its application temperature shows that the class 2 coal mine permissible emulsion explosive has good thermal safety.
