摘要:
为研究铝粉纳米化后对烟火药剂性能的影响,本文将普通铝粉和纳米铝粉分别与氯酸钾、硫粉按照零氧平衡的同一配比(17%AL+63%KClO3+20%S)配成的烟火药剂进行ARC热分析对比试验发现,含纳米铝粉的烟火药剂热分解的初始反应温度降低,反应到达最大温升速率所需的时间延长,反应所能达到的最高压力降低。这说明纳米铝粉的加入在加速其反应进程的同时,可有效地降低其反应的激烈程度和危险性,即铝粉纳米化后可以有效的改善烟火药剂的性能,提高其安全性。
Abstract:
By the ARC thermal analysis test to the pyrotechnics with the same proportion(63%KClO3+17%AL+20%S)composed by potassium chlorate, aluminum powder and sulfur powder according to zero oxygen balance, It was found that the nanoaluminum powder can effectively reduce the initial reaction temperature and the maximum pressure reached in the thermal decomposition reaction, and extend the time required to reach the maximum temperature rising rate, This result showed that the addition of nanoaluminum powder can effectively accelerate its reaction process, reduce its reaction intensity and danger.That is to say, the nanoaluminum powder can effectively change the performance of pyrotechnics and improve their security.
