热气溶胶灭火剂配方的研究进展

Research Progress in the Formulation of Hot Aerosol Fire Extinguishing Agent

不像传统的惰性气体、泡沫、水雾和哈龙灭火剂,热气溶胶灭火剂不需要高压气体来驱动,并且能在较低灭火浓度(30~200 g/m^3)下灭火。相比于基于钾盐的第一代和第二代热气溶胶灭火技术,第三代极大解决电器设备和电子的腐蚀问题。对第二代和第三代热气溶胶灭火剂的配方进展进行综述。并指出,灭火效率、燃烧温度和燃烧稳定性是未来热气溶胶灭火剂配方研究要关注和予以解决的问题。

Unlike traditional inert gas, foam, water mist and Halon fire suppression agents, hot aerosol fire extinguishing agents do not need to be driven out by pressurized gases and can extinguish fire at 30 to 200 g/m^3. Generally,the hot aerosol fire extinguishing technology has developed from generationⅠto generation Ⅲ（S-type）. Compared to potassium salt based generationⅠⅡ hot aerosol fire extinguishing technology, S-type greatly solves the corrosion problem of electrical devices and electronics. In this paper, research progress of the formulation of generation ⅡⅢ hot aerosol fire extinguishing agents was summarized. Moreover, it＇s pointed out that problems of extinguishing efficiency, combustion temperature and combustion stability of hot aerosol fire extinguishants should be paid attention to and solved in research on the formulation of aerosol fire extinguishing agents in the future.
