The interaction between ADN and (NC+NG) was studied by isothermal and non-isothermal thermogravimety. The mechanism functions and apparent activation energy and pre-exponential constant have been fitted and calculated by the Arrhenius method, and at same time compared the dates with calculated by Kissinger’s and Ozawa’s method. The result showed that using isothermal thermogravimetric analyzer method studied interaction and model function of(NC+NG)/ADN (1:1) mixture system was trusty and in reason,in selected testing temperature compared NC/NG single system and ADN single system with (NC+NG)/ADN mixture system and found that model function have not changed in evidence,apparent activation energy and activation velocity have varied, at atmospheric pressure and isothermal condition, there being interaction at double-base bond (NC/NG) with oxidizer (ADN).
The kinetic parameters of thermal explosion tests with five-second delay for 273 energetic materials were analyzed. The compensation effect exists between the two thermal explosion kinetic parameters of these energetic materials, e.g. lnA and Eb. The kinetic parameters of these energetic materials can be expressed by a single linear regression equation for the single compound or mixture under all conditions. The slopes of the regression equation for various systems are in the range from 0.1952 to 0.2413 (mol•kJ-1). The regression equation for single compound or mixture with one type of energetic material as main component has better linearity. Therefore, their “iso-kinetic temperature” Tik is close to their thermal explosion temperature Tb and the “iso-kinetic delay period”τik is also close to the 5 seconds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
