摘　　要：A类泡沫是一类新型火灾安全防护产品,先前研究侧重定性和半定量的灭火性能评估,通过标准木垛火试验,定量评价A类泡沫灭火剂灭A类火性能,探索不同混合比、发泡倍数等使用条件对灭火性能的影响,并与普通水的灭火性能进行比较。结果表明,在相同供给强度下,在压缩空气泡沫系统中使用A类泡沫灭火剂灭A类火,灭火速度相比普通水快20%以上。并且当混合比在0.2%～0.5%,发泡倍数在5～15倍,灭火效果较好。而按照木垛火得出的适宜使用参数,经大量灭火实战检验,其同样有效。Class A foam is a new kind of fire safety protective production. Previous studies focused on qualitative and semiquantitative extinguishing performance evaluation, but in this paper, experimental study was conducted to quantitatively eval uate the performance of class A foam in extinguishing class A fires by standard wood crib fire test. The effect of mixing ratio, expansion and other parameters on extinguishing performance was investigated, and was compared with the performance of water. The results here suggested that the extinguishing speed using class A foam in compressed air foam system is at least 20 faster than water in extinguishing class A fires at the same application rate. The best extinguishing effect was achieved at the mixing ratio in the range of 0.2%-0.5% , and the expan sion in the range of 5 - 15. The optimum factors obtained in wood crib fire test ware still effective in a large number of fire fighting.
