Safety Risk Analysis of Nitro Gradiently Distributed Propellant Preparation Process
摘要
Abstract
Nitro gradiently distributed propellant(NGDP),as a new type of propellant,has the characteristics of high oxygen balance,less harmful for use,and anti-migration.To analyze the thermal hazard of denitration reaction in the preparation pro-cess of NGDP,the exothermic process during the denitration reaction and the thermal decomposition behavior of the material,the reaction was measured by reaction calorimeter(RC1mx),differential scanning calorimeter(DSC)and accelerated adiabatic calorimeter(ARC).The results showed that the exothermic amount of the denitration reaction was 61.46 kJ,and the adiabatic temperature rise(△Tad)of the reaction system calculated from this was 58.28 ℃.In the DSC test,the denitration treatment in-creased the decomposition temperature of the double base propellant from 191.33 ℃ to 194.16 ℃.Based on the ARC test data of the post-reaction system,the relationship between the Time to Maximum Rate(TMRad)and the temperature was calculated.When the adiabatic induction period is 24 hours,the corresponding TD24 is 137.2 ℃.The TD24,maximum technical temperature(MTT),and maximum temperature of the synthesis reaction(MTSR)of the reaction are 137.2,108 ℃,and 128.52 ℃,which means that the system had the risk of spraying in case of cooling failure.However,the risk of triggering the secondary decompo-sition reaction was low.关键词
