摘要本文主要对硝化棉基微孔含能材料的结构与燃烧特征研究，以期望提高其传火速度，这必将是无烟药替代黑火药应用于烟花产品，实现烟花燃放的无烟/微烟燃放的关键技术。

通过测定燃速的方法，可以对硝化棉基的燃烧性能进行表征；通过对微孔含能材料结构的表征可以分析出其孔结构与其燃烧性能之间的密切联系。实验测得原料微孔含能材料的结构，燃烧速度，烟雾性能等，再查阅资料获取黑火药的相关数据，通过比较的方法进行分析讨论。63637

通常情况下，黑火药的传火速度约为8mm/s.而本试验采取改变装药条件，添加氧化剂等手段，得到的传火速度均在200mm/s左右。从结构上来看有孔的药品传火速度明显要高于无孔含能材料；欲提高微孔含能材料的燃速，要适当增加孔径，或者增加氧化剂的比例，选择不同的材料，对传火速度也有较大影响。另一方面，本实验用微气孔球形药燃烧后烟雾透光率都高于80%，而黑火药透光率只有2%。充分说明微气孔球形药在烟雾性能上较黑火药而言有优异的环保性能。

Title  The study of Porous energetic materials structure and combustion characteristics                                                          

Abstract This paper mainly focus on the nitrocellulose microporous material structure and combustion characteristics of research,  expecting to improve the speed of fire spreading, it will be a smoke-free medicine instead of black powder used in fireworks products, achieving fireworks smoke-free smoker micro setting off key technology.

By using the method of measuring burning rate, can the nitrocellulose based combustion performance were characterized. Through the characterization of energetic microporous structure material, we can easily know the connections between pore structure and its combustion performance. Experiment measured the microporous structure of energetic material, burning speed, the smoke performance, etc, then consult the data using data on black powder, finally ,it  is analyzed by using the method of comparison discussion.

Normally，the burning spreading speed is 8mm/s.Experimental results show ,after changing the test conditions ,the speed is about 200mm/s.The drugs from the structure have the hole fire speed significantly higher than non hole materials, and with the view point of increase the burning rate, to appropriately increase the aperture, or increasing the proportion of oxidant is a great way, and also the choice of different materials, have great influence to spread speed of fire. On the other hand, this experiment using micro pore spherical combustion smoke light transmittance were all higher than 80%, while black powder light transmittance is only 2%.Therefore micro pore spherical medicine compared with black powder on the smoke properties is with excellent environmental performance.
