Ammonium nitrate-fuel oil (ANFO) explosives are inexpensive and readily produced, but are highly prone to misfires, with the remaining explosive being a significant risk and environmental contaminant. In this work, studies on various additives, such as selected perchlorates and inorganic peroxides, which are intended to lower the susceptibility of ANFO to misfires by increasing its sensitivity to shock, have been conducted. These studies showed the viability of using these additives in ANFO, allowing for conducting shock wave sensitivity tests for bulk charges in the future. We investigated the effects of introducing these additives into ANFO (on its sensitivity), as well as thermal and energetic properties. We observed minor increases in friction and impact sensitivity, as well as a moderate reduction in the decomposition temperature of the additive-supplemented ANFO in comparison to unmodified ANFO.
硝酸铵-燃油(ANFO)炸药价格低廉且易于制造,但极易出现哑炮现象,剩余炸药存在重大风险且会造成环境污染。在本研究中,已对各种添加剂进行了研究,例如选定的高氯酸盐和无机过氧化物,其旨在通过提高ANFO对冲击的敏感性来降低其出现哑炮的可能性。这些研究表明在ANFO中使用这些添加剂是可行的,这使得未来能够对散装炸药进行冲击波敏感性测试。我们研究了将这些添加剂引入ANFO(对其敏感性)以及热性能和能量性能的影响。我们观察到,与未改性的ANFO相比,添加添加剂的ANFO的摩擦和冲击敏感性略有增加,分解温度适度降低。
