试验表明,膨化硝铵炸药的药卷密度对其爆炸后的有毒气体生成量有影响,一般药卷的装药密度在0.85～0.95g/cm~3时,炸药的有毒气体生成量是合格的;而当装药密度大于1.00g/cm~3时,由于密度过大,使体系结构密实,炸药组份间的空隙率减小,而致反应不完全,结果造成炸药爆炸后的有毒气体总量超过MT60标准规定的指标。 The experimental results show that the density of the expanded ammonium nitrate explosive has an impact on the amount of toxic gas generated after the explosion. When the drug density of the general drug coil is between 0.85 and 0.95 g / cm ~ 3, the toxic gas generation of the explosive is acceptable ; When the density of charge is more than 1.00g / cm ~ 3, the density of the system is too large, the density of the system is so high that the voidage of the explosive components decreases and the reaction is incomplete. As a result, the total amount of poisonous gas after explosion The quantity exceeds the standard that the MT60 standard stipulates.
