混合硝酸酯安定性试验温度的一致性研究

Abel Stability Test of Mixed Nitric Ester at Different Temperatures

为了缩短阿贝尔安定性试验周期,降低硝酸酯生产线上危险品的在制量,以硝化甘油基的混合硝酸酯及其相应的含能粘合剂为试样,通过试验温度对比实验,研究了试验温度对安定性测试结果的影响,结果表明:对于硝化甘油基混合硝酸酯及含能粘合剂,30 min/72℃、15 min/80℃及12 min/82℃三个安定性测试方法是一致的。而且15 min/80℃、12 min/82℃的试验方法相对于30 min/72℃的试验方法可以大大缩短试验周期,提高分析速度。

In order to shorten the test cycle of Abel stability and reduce amounts of the nitric ester in production line ,the influence of temperature on the stability test result was studied using the NG-based mixed nitric ester and the relevant energetic binder as samples. The results of three stability test methods,i, e. 30 min/72 ℃, 15 min/80 ℃ , 12 min/82 ℃, are unanimous, and that the test methods at higher temperature can shorten the test cycle significantly and improve the analysis speed.
