摘　　要：开展实验来探索温度对水成膜泡沫灭火剂的发泡倍数、析液时间及表面张力的影响,研究水成膜泡沫灭火剂性能受温度影响的规律。结果表明,在一定温度范围内,水成膜泡沫灭火剂的发泡倍数、析液时间随温度正相关变化,而表面张力却呈现负相关,但均趋于稳定;温度不会对水成膜泡沫灭火剂的性能造成严重影响。实验结论为我国受温度影响较大地区的水成膜泡沫灭火剂使用提供科学参考。A series of experiments were conducted to examine the impact of temperature on the foam expansion ratio,the drainage time and the surface tensionof the aqueous film-forming foam extinguishing agent,to study the rules of the influence of temperature on the fire suppression performance of the agent.The results showed that,there is a positive relation for the foam expansion ratio and the drainage time with the temperature while a negative relation for the surface tension with the temperature of the agent,but the parameters all tend to be a constant;temperature won＇t have serious influence on the performance of the agent.The study can provide information for the use of the aqueous film-forming foam extinguishing agent where large temperature difference exists.
