| 摘 要： | 使用加速量热仪(ARC)研究了三种爆竹类药剂(主要氧化剂分别为:KClO3、KNO3、KClO4)的热安全性,依据它们的热分解温度和压力随时间的变化曲线以及温度上升速率随温度的变化曲线,分析了其热分解过程并计算了热分解过程表观活化能Ea和指前因子A。测试和分析结果表明,以KClO3为氧化剂的烟火剂较以KNO3、KClO4为氧化剂的爆竹热安全性差。

| Abstract: | The thermal safeties of three kinds of firework(70/20/10-KClO3/Al/S,70/20/10 KNO3/Al/S,and 67/20/13 KClO4/Al/S mixture) were studied by accelerating rate calorimeter(ARC).The curves of thermal decomposition temperature and pressure versus time,and the reaction rate versus temperature were obtained,moreover,the thermal decomposition processes were discussed.The apparent activation energy and pre-exponential factor of this reaction were also calculated.The results show that the thermal safety of potassium chlorate mixture is the lowest among the three kinds of firework. |
