摘　　要：为研究气溶胶灭火剂在工程应用中所产生的高温问题,采用了对比试验方法,分别在气溶胶灭火装置内添加降温物质和选用隔热材料,对其喷口温度进行测试。结果表明:当添加的KHCO_(3)为2%时,气溶胶灭火剂的燃烧温度明显降低;实验中选取轻质碳酸镁作为降温物质,其降温效果好、灭火时间短;珍珠岩棉的厚度为20 cm的时候效果最佳,此时喷口最高温度为63℃。研究为降低气溶胶灭火剂的喷口温度提供了理论参考和技术支持。In order to study the high temperature problem of aerosol fire extinguishing agent in the process of practical application,the method of comparative test was used.By adding cooling material KHCO_(3) to the aerosol fire extinguishing agent,and adding heat insulation material,the test was carried out on the nozzle temperature.The results showed that the combustion temperature of aerosol fire extinguishing agent decreases obviously when the addition of KHCO_(3) is 2%.The light magnesium carbonate selected in the experiment has good cooling effect and short fire extinguishing time.When the thickness of pearl rock wool is 20 cm,the effect is the best,and the highest temperature of the nozzle is 63℃.It provides theoretical reference and technical support for reducing the nozzle temperature of aerosol fire extinguishing agent.
