Description

technical field [0001] The invention belongs to the technical field of risk assessment of energetic materials, and mainly relates to a method for determining the temperature correction coefficient of the compounding process of energetic materials. 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 explosion...

Problems solved by technology

[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
