N2 - In order to obtain the critical temperatures of energetic materials thermal reaction in different scales, a multi-scale thermal reaction test system has been developed. In this experiment, the measurement method of thermal diffusivity of energetic materials under test conditions is added. Based on the measured thermal diffusivity in thermal reaction test, activation energy and pre exponential factor measured in laboratory. The critical temperatures of thermal reaction in different scales of DINA are calculated, the calculation results are verified by two different scale thermal reaction tests, and the test results are in good agreement with the calculation results. According to the above calculation method, the critical temperature of thermal reaction of DINA under actual process conditions is obtained; it provides the basis of safety data for enterprise safety production.
