摘要:
为改善泡沫灭火剂的高温稳定性和抗复燃性能,将石墨粉、膨润土和空心玻璃微珠按一定比例复配加入泡沫灭火剂中制备防灭火三相泡沫,利用自主设计的实验台架,研究其发泡、稳泡及油面热稳定性等主要性能,分析复配超细粉体对泡沫灭火剂稳定性的影响机理。实验证明,复配粉体的加入可使泡沫灭火剂在高温下的稳定时间延长10倍以上,粉体颗粒会在泡沫表面形成一层致密壳层,增强泡沫的隔热阻燃性能,石墨粉的存在使壳层更加致密且增强了泡沫的流动性,但会对泡沫的发泡性能产生较大的影响,当空心玻璃微珠和石墨粉的添加质量比为5∶2时,整体效果较好。
Abstract:
To improve the high temperature stability and anti-reflash performance of foam fire extinguishing agent, the three-phase foam for fire extinguishing was prepared by incorporating the remixed ultrafine powders with graphite powder, bentonite and hollow glass microspheres according to certain ratio into the foam fire extinguishing agent. The main performance such as foaming, stability and thermal stability on oil surface were tested on a self-designed experiment bench, and the influence mechanism of remixed ultrafine powder to stability of foam fire extinguishing agent was analyzed. The results showed that the addition of remixed powder can extend the stable time of foam fire extinguishing agent under high temperature for more than 10 times. The powder particles can form a layer of dense shell on the surface of foam, so as to increase the performance in heat insulation and flame retardant of foam. The existence of graphite powder can make the shell layer more denser and increase the fluidity of foam, but cause larger influence on the foaming performance of foam. When the addition mass ratio of hollow glass microspheres and graphite powder is 5:2, the overall effect is better.
