摘要: 为提高铵油炸药(ANFO)雷管起爆感度和作功能力，向ANFO中加入不同的添加剂。借鉴板痕试验原理，设计了用于比较ANFO雷管起爆感度和作功能力的试验装置和方法，采用该方法测试了含添加剂的改性ANFO的起爆感度和作功能力。实验结果表明，所选择的几种添加剂对ANFO雷管起爆均有敏化作用，同时也都能提高ANFO的作功能力，其中Al、高氯酸铵(AP)提高ANFO作功能力的效果比NaNO2、玻璃微球和AC发泡剂更显著。分析了添加剂对ANFO雷管起爆感度和作用能力影响的机理。

Abstract: Different additives were added to ANFO to enhance its detonator initiation sensitivity and work capacity. Based on the principle of the plate trace test, the test device and method were proposed to compare detonator initiation sensitivity and work capacity of ANFO containing additives. The results show that all the selected additives can improve detonator initiation sensitivity and work capacity of ANFO. Among these additives, Al and AP have stronger effects on the work capacity of ANFO than glass microballoon particles, AC foaming agent and NaNO2. The effect mechanisms of these additives were analyzed respectively.
