| Abstract: |
| In order to analyze the stability of high explosive of TNT/RDX/Al in some waste projectile warhead, accelerated aging experiment was performed on the explosive sample, and thermal decomposition process of the original sample and the aged sample was measured with the help of differential scanning calorimeter. DSC curve and relative characteristic parameters were got under different warming rates of 5, 10, 20 ℃/min. Ozawa model and regression analysis were applied to calculate the kinetic parameters. The result showed that average change of the peak temperature is 1.08℃ and alteration of activation energy is 8.01%. It was concluded that the stability of the TNT/RDX/Al explosive is good and meets the recycle demand. |
