| 摘 要： | 为了了解HMX粉尘与FOX-7粉尘的燃爆特性,评价其潜在危险性,利用1.2 L哈特曼管式粉尘云爆炸装置,分别对粉尘浓度、粒度、环境湿度对两种物质最小点火能(E_(min))的影响进行了研究与分析。研究结果表明:2类HMX、5类HMX与FOX-7三种粉尘着火的最敏感浓度分别为916.66 g·m~(-3)、833.33 g·m-3与833.33 g·m-3;所对应的Emin分别为12.45 m J、15.75 m J、19.01 m J。粉尘浓度、环境湿度对两种物质的最小点火能均有显著影响;最小点火能随粒度的减小而降低。

| Abstract: | Abstract] In order to understand the explosion characteristics of HMX dust and FOX-7 dust, the potential risk was evaluated. The effects of dust concentration, particle size and environmental humidity on the minimum ignition energy (Emin) of two substances were studied by 1.2 L Hartmann tube dust cloud explosion device. The results showed that the most sensitive concentrations of 2HMX, 5HMX and FOX-7 were 916.66 g·m-3,833.33 g·m-3 and 833.33 g·m-3, respectively, and Emin were 12.45 mJ, 15.75 mJ and 19.01 mJ respectively. Dust concentration and ambient humidity have a significant effect on the minimum ignition energy of both materials and the minimum ignition energy decreases with the decrease of particle size. |
