Kinetic compensation effect of kinetic parameters of thermal explosion test

摘要

The kinetic parameters of thermal explosion tests with five-second delay for 273energetic 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.
