摘要:
In order to conduct the cause investigation of an explosive incident by raw pyrotechnics mixtures, various hazard evaluation tests were performed. Explosions occurred during manufacturing fire-works, which consisted of potassium perchlorate (KClO4), aluminum (Al) powder and antimony trisulfide (Sb2S3). Identification of the explosive materials was conducted by sampling of soil at the explosion places including craters and analyzing them. Though we found it was very stable thermally, at least up to 500 ℃ based on the results of DSC and TG-DTA, it appeared high sensibility in friction and falling impacts. By the gap test (sympathetic detonation test), we found it was easy to develop sympathetic detonation. Therefore, more careful treatment is needed when we manufacture, treat or consume these materials.
Abstract:
利用几种危险性评价方法,研究烟火药剂原材料混合物引发爆炸事故的原因。爆炸事故发生于烟花制造过程中,通过采集、分析爆炸现场炸坑的土壤,发现爆炸物质由高氯酸钾(KClO4)、铝(Al)粉及硫化锑(Sb2S3)组成。尽管DSC、TG-DTA数据表明该混合物热稳定性好,分解温度高达500 ℃,但是,其摩擦感度及撞击感度却很高。间隙试验(殉爆试验)显示该混合物容易发生殉爆。因此,在制造、处理以及使用这些物质时必须格外谨慎。
