Method for determining temperature correction coefficient of energetic material chemical combination process

Abstract

The invention discloses a method for determining a temperature correction coefficient of an energetic material chemical combination process. The method comprises the following steps: according to thermal decomposition kinetic parameters of energetic material chemical combination process materials under an adiabatic condition, obtaining the highest synthetic reaction temperature corresponding to maximum reaction rate arrival time under the adiabatic conditions of different danger levels; and taking the highest temperature and the specific operation time of the synthetic reaction corresponding to the arrival time of the maximum reaction rate under the adiabatic conditions of different danger levels as scales, comparing and measuring the highest temperature which can be reached by the actualsynthetic reaction and the actual process operation time, and quantitatively determining the temperature correction coefficient of the energetic material chemical combination process.

Description

technical field [0001] The invention belongs to the technical field of safety assessment of energetic material compounding process, in particular to a method for determining the temperature correction coefficient of energetic material compounding process. Background technique [0002] Energetic materials are prone to combustion and explosion under thermal, static, mechanical and other stimuli. Carrying out the risk assessment of combustion and explosion in the compounding process of energetic materials is an important part of safety production design and control. The material in the energetic material compounding process is a poor conductor of heat and is extremely sensitive to thermal stimulation. It will undergo self-catalytic decomposition and exothermic reaction when heated, and it is easy to generate heat accumulation and cause thermal explosion, which is the inducing factor of a large number of safety accidents. Therefore, the process The assessment of combustion and e...

[0019] It can be seen from Table 1 that the temperature correction coefficient γ 1 The method of determination is a semi-quantitative method. Although there are corresponding evaluation parameter values, the actual operability is poor, and the values ​​cannot be accurately quantified one by one. Moreover, the connotation of the concept of value conditions is not clear, and there is a lack of quantitative criteria, so it is difficult to be effective with actual process conditions. Combined with the evaluation of the hazard degree of process materials
