摘要:采用理论计算与试验方法对某含HMX的高能点火药性能进行了研究。结果表明：理论计算与试验结果基本相符，随着HMX含量的增加，该点火药输出能量变化小，爆热值均大于9 000J/g；残渣量略有减少，均大于80%；同时，药剂比容明显增大。热分析实验表明：HMX与Mg-Al合金、KClO4具有良好的相容性，加入HMX后点火稳定性增强；感度测试结果表明：HMX含量从5%增加至10%时，点火药的撞击感度增加，摩擦感度与火焰感度无显著变化。
Abstract:Calculating and testing studied the performance of a new HMX-containing high energetic ignition mixture. The result showed that the test result accorded with the theoretic calculation essentially. As the content of HMX increased, the output energy changed a little, the explosion heat was over 9 000J/g, the amount of solid residua decreased a little, which was over 80%, , and the specific volume increased evidently for the ignition mixture. The test results by DSC showed that, the mixture of HMX, Mg-Al alloy and KClO4 has a good compatibility. After adding HMX into the mixture of Mg-Al alloy and KClO4 , the igniting stability can enhance. Sensitivity tests showed that, when the content of HMX increased from 5% to 10%, the impact sensitivity enhanced in some sort, while the friction sensitivity and flame sensitivity almost didn’t change.
