炸药 Explosive material

(重定向自Blasting agent)
爆炸示范

炸药Explosive material)是在一定的外界能量的作用下,由自身能量发生爆炸的物质。一般情况下,炸药的化学及物理性质稳定,但不论环境是否密封,药量多少,甚至在外界零供氧的情况下,只要有较强的能量(包括但不限于由起爆药所提供)激发,炸药就会对外界进行稳定的爆轰式作功。炸药爆炸时,能释放出大量的热能并产生高温高压气体,对周围物质起破坏、抛掷、压缩等作用。炸药能以其不同的性质去分类,例如以其扩张的速率去划分。一种物质如能产生爆轰(Detonation),即爆炸速度较音速要快的称作「猛炸药」;如只能产生爆燃(Deflagration),即爆炸速度慢于音速,即称作「低速炸药」如火药或发射药,现在使用上有别于炸药的。如以「爆感度」划分,即可分作一、二及三类,如只需极少能量或压力即可引爆的称作「起爆炸药」或「一级炸药」(primary explosives),爆感度较低的即可称作「传爆炸药」或「二级」及「三级炸药」(secondary or tertiary explosives)。
