摘要
Abstract
The thermal decomposition processes of TNPyO and its moulding powders were studied by TG method at heating rates of 5, 10, 15, 20K/min, respectively. The thermal decomposition kinetic parameters and the mechanism functions of TNPyO and its moulding powders were obtained by the integral iso-conversional non-linear method and Ozawa's method. The results show that TNPyO and its moulding powders have better thermal stability below 231 ℃. The thermal decomposition mechanism of TNPyO explosive and its moulding powders are classified as random nucleation and growth of n-1. The activation energy (E) , pre-exponential factor (A) and mechanism function of the thermal decomposition process of TNPyO are 344. 01 kJ/mol, 3. 796 × 1031 and/(α) = (1 - α), respectively. The thermal decomposition kinetic equation is dα/dt = 3. 796 × 1031 × (1 -α)exp( - 3. 4401 × 101 /T).关键词
