无木炭型黑火药研究

以酚酞和氢氧化钾的反应物替代木炭，通过调整硝酸钾、硫磺、酚酞及氢氧化钾的混合比例对无木炭黑火药配方进行优化设计，对比研究了普通黑火药与无木炭黑火药在机械感度、静电火花感度、热分解过程及输出特性等方面的差异。研究认为：无木炭黑火药的机械感度、静电火花感度、爆发点比普通黑火药低，而且安全性好，做功能力强，输出稳定性高。

Study on Charcoal-free Black Powder

Through modifying proportions of potassium nitrate, sulfur, phenolophthalein and potassium hydrate, formula of charcoal-free black powder is optimized by replacing charcoal with reactant of phenolphthalein and potassium hydrate. Properties between ordinary black powder and charcoal-free powder are compared, including mechanical sensitivity, static eletricity sensitivity, thermal decomposition process and output capacity. The results indicate that the mechanical sensitivity, static electricity sensibility and ignition temperature of charcoal-free black powder is lower than that of ordinary black powder, and the safety ability, working capacity and output stability of charcoal-free black powder is higher than that of ordinary black powder,
