摘要:
文章对粉状乳化炸药的爆温进行了计算：用B-W法确定了粉状乳化炸药的爆炸反应方程式,用盖斯定律以炸药原料和爆炸产物各组分的定容生成热为基础计算了其定容爆热,用加权法算得了爆炸产物的摩尔定容热容,最终计算得到岩石粉状乳化炸药的爆温为2695 K,一级、二级、三级煤矿许用粉状乳化炸药的爆温依次为2651 K、2597 K、2510 K.计算结果显示随着氯化钾含量的增加,煤矿许用粉状乳化炸药的爆热、爆温均呈现降低的趋势.当氯化钾含量在4%～9%范围内递增时,炸药的爆热、爆温的降低与氯化钾含量呈线性关系.
Abstract:
The explosion temperature of powdery emulsion explosives are calculated in this paper. The explosion reaction equation of powdery emulsion explosives are confirmed with B—W rule, and the constant volume explosion heat of powdery emulsion explosives are calculated with Hess law according the constant volume heat of formation of the explosives ingredients and explosion products. Specific heat capacity (SHC) of explosion products is calculated with the method of weighted averages. The result shows that the explosion temperature of rock powdery emulsion explosive is 2695K, the explosion temperature of class I、II、III coal mine permissible powdery emulsion explosives are 2651 K, 2597 K, 2510 K respectively. According to the calculations, it can be seen that the explosion heat and explosion temperature of permissible powdery emulsion explosives decrease respectively with the increase of contents of KCl. As the content of KCl increase in the 4%~9%, the explosion heat and explosion temperature of the explosive are linearly related to the content of the KCl.
