摘要:
通过对多孔粒状铵油炸药、3种常用的重铵油炸药(乳胶基质与多孔粒状铵油炸药的质量比分别为25︰75、50︰50、75︰25)、乳化炸药运用B-W规则,确定重铵油炸药的爆炸反应方程式.用盖斯定律计算重铵油炸药的定容爆热,用加权法计算该炸药爆炸产物的摩尔定容热容.结果表明:随着乳胶基质含量的增加,重铵油炸药的爆热、爆温值均呈下降趋势;通过Origin软件对其数据进行分析,得出了乳胶基质含量对其爆热、爆温的影响近似呈线性关系以及乳胶基质含量对爆热的影响较之于对爆温的影响明显的结论.
Abstract:
Porous granular anfo explosive, three frequently used heavy anfo (HANFO) explosives(mass ratio of emulsion matrix and porous granular anfo were 25︰75,50︰50 and 75︰25, respectively) and emulsion explosive used in blasting engineering were studied to establish the explosion reaction equation of HANFO explosive based on B-W rule. Con-stant volume explosion heat of HANFO explosive was calculated based on Hess Law;and its specific heat capacity ( SHC) was counted with the method of weighted averages. Calculations show that explosion heat and explosion temperature of HANFO explosive decrease with the increase of the content of emulsion matrix. Interpret data by Origin software indicate that influences of emulsion matrix content on the constant volume explosion heat and the explosion temperature of HANFO explosive are approximately linear, and influence of emulsion matrix content on the constant volume explosion heat is greater than that on explosion temperature.
