摘要
为探索环境湿度对某新型推进剂热分解的影响规律,用盐的饱和溶液模拟了不同的环境湿度条件,用微热量仪对该推进剂进行等速升温实验,获得了不同湿度条件下的热流曲线特征数据,并对实验结果进行处理与分析。结果表明,湿度对反应热的影响不大;开始加速分解温度随湿度的增加而减小;从开始加速分解到反应速率最大所需时间也随湿度的增加而减小。
To explore the influence rule of environmental humidity on thermal decomposition of a new type propellant, the environmental conditions with different humidity in the experiment were achieved by manual simulating with saturation solution of salt. A constant heating-rate experiment of the propellant was performed on a microcalorimeter, The characteristic data of heat flow curves of the propellant were obtained under the different humidity .conditions. The experimental results were treated and analyzed. The result indicated that the humidity has little impact on the reaction heat. The initial accelerating decomposition temperature and the time needed from initial accelerating decomposition to maximum rate decrease with increasing the humidity.
