摘要:本文测定了不同配比的硼/铅丹烟火药剂的燃速、燃烧反应热等参数,通过差热分析、X射线衍射分析等方法,对其燃烧性能进行了研究并对产生差异的原因进行了讨论。结果表明:硼粉质量分数达3.0%以上时,易发火,点火能力较强,趋近于1.0%时点火能力明显减弱。
Abstract:Different ratio of B/Pb3O4 pyrotechnic compound were studied, and the parameters such as burning rate, heat of combustion reaction were measured. The methods such as DTA\X-ray diffraction are used to analysis the combustion performance, and the reason which made the difference was analyzed. The result shows that, the fire for the B/Pb3O4 system with the mass fraction of Boron of 73% easily took place and the igniting capability is much higher. If the number near 1.0%, the igniting capability decreased obviously.
