摘要
以航空煤油、航空汽油、97#车用汽油为原料,采用市场上常见的水成膜泡沫灭火剂6%型及新型生物可降解水成膜泡沫灭火剂6%型,分别在四川广汉(海拔520m)、康定县城(海拔2 560m)和康定机场(海拔4 290m)开展试验,研究20℃时高高原环境对AFFF物化性能的影响,并分析其原因,对比两种AFFF受海拔高度影响的程度。研究发现两种泡沫灭火剂的表面张力、灭火剂与三种油品之间的界面张力、铺展量及发泡力均随海拔高度的上升而下降,铺展系数与析液时间则随海拔高度的升高而增大。
The aviation kerosene, the aviation gasoline and the 97 gasoline were selected as experiment materials, the effects of high plateau environment on the physical and chemical proper- ties of the AFFF at 20 ℃ were studied. The experiments were carried out at the following places： Guanghan（plateau 520 m）, Kangding County（plateau 2 560 m） and Kangding Airport（plat- eau 4 290 rn）. Commercial 6% AFFF and biodegradable 6% AFFF were used in the experiments. The results showed that the surface tension, interfaeial tension between AFFF and oil, spreading amount and foaming power decreased with the in- creasing altitude. However, the drainage time and spreading coefficient showed an opposite changing trend.
