摘要
为了完善无水肼的危险等级分类,依据联合国橘黄书爆炸品危险性分级程序,对制式包装无水肼(包括2种尺寸:18 kg和120 kg)分别开展EIDS隔板试验和外部火烧试验。分别采用高速摄像、红外热成像和压力数采测试系统表征样品在火灾刺激下的燃爆过程、火球表面最高温度以及冲击波效应。结果表明:外部火灾条件下,无水肼‑18 kg样品的TNT当量为0.724,是无水肼‑120 kg样品的1930.67倍。无水肼在特定条件下具有明显的爆炸特性,不同制式包装设计压力下的无水肼分别显示出了1.1 C和1.3 C的危险等级。无水肼的危险等级分类与其包装设计压力联系密切,应在实际使用允许范围内,降低无水肼等液体推进剂的包装强度,以有效降低其危险性。
To improve the hazard classification of anhydrous hydrazine,the extremely insensitive detonating substance(EIDS)gap test and external fire test were conducted for the standard packaging anhydrous hydrazine(18 kg and 120 kg)in accordance with the United Nations“Recommendations on the Transport of Dangerous Goods,Manual of Tests and Criteria”.The deflagration process,the highest temperature of the fireball surface and shock wave effect of samples were obtained by a high‑speed camera,an infrared thermal imaging and a shock wave pressure acquisition system.The experimental results show that,under external fire conditions,the TNT equivalence of the anhydrous hydrazine‑18 kg was 0.724,which was 1930.67 times that of anhydrous hydrazine‑120 kg.Under certain conditions,anhydrous hydrazine has obvious explosive properties and can be assigned to Division 1.1 C or Division 1.3 C for different packaging design pressures.The hazard class of anhydrous hydrazine is closely related to the standard packaging design pressure.For safety purposes,the design pressure of packaged anhydrous hydrazine should be properly reduced within the allowable range to effectively reduce its hazard.
