新型复合油相乳化炸药基质的非等温热分解特性
Non-isothermal Thermal Decomposition Characteristics of Emulsion Explosive Matrix Prepared by the New Type of Complex Oil Phase
摘要
Abstract
In order to grasp the thermal decomposition characteristics of emulsion explosives prepared by the new complex oil phase, the non-isothermal thermal decomposition process of emulsion explosive matrix was tested by TG-DTG technology in nitrogen atmosphere.The corresponding kinetic parameters such as activation energy(E) and pre-exponenitial factor(A) were obtained according to the Kissinger and Ozawa methods.The thermal decomposition mechanism of the emulsion explosive matrix was predicted by the model fitting method, and was further verified by the model-free method.The results show that the average activation energy E and pre-exponenitial factor lg(A/s-1) are about 142.12kJ/mol and 13.26 respectively in the conversion rate range of 15%-95%.The thermal stability of emulsion explosive matrix prepared by new complex oil phase is better than that of the matrix prepared by complex wax.The thermal decomposition reaction mechanism follows the three dimensional (3D) diffusion control mechanism(n=2).关键词
