不同测试条件下炸药爆炸后有毒气体含量的差异研究

Study on the Difference of Toxic Gas Production in Explosive Explosion under Different Test Conditions

为研究在不同测试条件下工业炸药爆炸后有毒气体含量的差异,分别利用大爆炸箱常压测试装置和传统小弹筒测试装置对工业炸药进行起爆测试,分析比较了测试结果。结果表明:两种测试条件下测得的炸药爆炸后有毒气体含量存在明显差异,大爆炸箱中的有毒气体含量低于小弹筒中含量。在小弹筒测试条件下,现场混装炸药较难达到完全爆轰,导致炸药产生大量的有毒气体;说明传统小弹筒测试方法对于现场混装炸药爆炸后有毒气体含量的测试相对局限。研究结果对于工业炸药尤其是现场混装炸药爆炸后有毒气体含量测试方法的完善和建立提供理论支撑。

In order to study the difference of toxic gas production in explosion of industrial explosives under different test conditions,the detonation test of industrial explosives was carried out by using the atmospheric pressure test device of the large explosion box and the traditional small cartridge test device,respectively.Test results were analyzed and compared.Results show that there are obvious differences in output of explosive toxic gas measured by the two test devices.Toxic gas test results of the explosive in the large explosion box are lower than those in the small cartridge.In addition,under the test conditions of small cartridges,it is difficult to achieve complete detonation for mixed explosives on site,resulting in the generation of a large amount of toxic gas from the explosives.Furthermore,it is explained that the traditional small cartridge test method is relatively limited for the toxic gas test of mixed explosives on site.The research results provide theoretical support for the improvement and establishment of the test method for the toxic gas production of industrial explosives,especially mixed explosives on site.
