Abstract

In blasting in dense urban areas and piece stone mining, the issue of organizing gentle destruction modes arises, which requires the use of pyrotechnic compositions operating in the deflagration mode. In such compositions, ammonium perchlorate, ammonium nitrate, and other nitrates are used as oxidizing agents. Magnesium is often used as fuel. In this paper, the combustion of a three-component mixture of sodium nitrate, magnesium, and carbon was studied. The latter was obtained by carbonizing a walnut shell or grinding gas mask adsorbents. The thermodynamic calculations of combustion were performed, and the combustion characteristics of the NaNO₃/Mg/C mixture with a component ratio of 60/20/20 were measured.

含碳粉添加剂的产气组合物的燃烧研究

摘要

在密集城市地区的爆破和碎石开采中，出现了组织轻度破坏模式的问题，这需要使用以爆燃模式运行的烟火组合物。在这样的组合物中，高氯酸铵，硝酸铵和其他硝酸盐用作氧化剂。镁通常用作燃料。本文研究了硝酸钠，镁和碳的三组分混合物的燃烧。后者通过碳化核桃壳或研磨防毒面具吸附剂获得。进行燃烧的热力学计算，并测量组分比为60/20/20的NaNO ₃ / Mg / C混合物的燃烧特性。
