非爆炸且不可还原农用硝酸铵热分解反应动力学的研究

利用加速度量热仪分别对普通硝酸铵和非爆炸且不可还原农用硝酸铵的绝热分解过程进行分析,分析结果通过动力学模型编程在微机控制系统上进行数据分析处理,得到了绝热分解温度与压力随时间的变化曲线、自加热速率随温度的变化曲线、准速率常数随温度的变化曲线、最大温升速率所需时间随温度的变化曲线,计算了分解动力学参数表观活化能、指前因子、不可逆温度和自加速分解反应温度。所有实验结果都表明,非爆炸且不可还原农用硝酸铵具有良好的热稳定性、安全性。     

非爆炸且不可还原农用硝酸铵的改性研究与测试技术

Based on a study of the relationship of ammonium nitrate （AN） explosion and its thermal stability, inert agents were added to AN for eliminating the explosive characteristic of AN and in order to be irrestorable. The results of using a large quantity of experiments and various testing technologies show that the improvement on thermal stability of modified AN is the basic reason for eliminating explosive characteristic of AN. The modification scheme was considered to have the following features： reliable and stable technology, market-demanded product, low investment and good economic returns. And during the revamping period, the normal production of AN will not be af- fected, and the economic, social and environmental benefits are good.
