The effect of crystal structure on the thermal reactivity of CL-20 and its C4-bonded explosives Part II. Models for overlapped reactions and thermal stability

Popis výsledku v původním jazyce

The critical temperature and mechanism functions for thermal decomposition of epsilon-CL-20, RS-epsilon-CL-20, alpha-CL-20, epsilon-CL-20/C4, and RS-epsilon-CL-20/C4 were evaluated based on non-isothermal TG data. A two-step mechanism has been found forthermal decomposition of alpha-CL-20, epsilon-CL-20/C4, and RS-epsilon-CL-20/C4, where the initial step is partly controlled by crystal structure of CL-20. The more reasonable mean activation energies could be obtained after peak separation for each individual steps. In fact, the activation energy for the post integrated process is almost equivalent with that of the second step, indicating that the total activation energy at the main decomposition process is dominated by thermolysis of CL-20 molecular.Besides, it has been found that the decomposition of C4 matrix does not affect the decomposition of normal epsilon-CL-20, resulting in identical activation energy and reaction model. However, the interaction between the C4 matrix and RS-e
