摘要
以高稳定性压缩空气泡沫灭火剂为研究对象,采用1.73 m^2标准火试验模型,对比考察了不同泡沫产生系统、不同发泡倍数以及不同燃料类型对水溶性液体火灭火及抗烧性能的影响。试验结果表明,抗溶泡沫灭火剂在压缩空气泡沫系统中的泡沫稳定性、灭火时间和抗复燃时间均显著优于低倍数泡沫系统;在压缩空气泡沫系统中,抗溶泡沫的抗烧性能随着发泡倍数的增大而降低;丙酮火的灭火难度高于乙醇火,建议在选用抗溶泡沫灭火剂时针对水溶性液体特点开展针对性的灭火试验评估。
Taking high stability compressed air foam fire extinguishing agent as research object,the 1.73 m^2 standard fire test was used to compare the effects of different foam generation systems,different expansion and different fuel types on watersoluble liquid fire extinguishing with high stability alcohol-resistant compressed air foam.The experimental results showed that the foam stability,extinction time and burnback time of alcohol-resistant foam in compressed air foam system are significantly better than that of traditional foam system.The burnback performance of the foam decreases with the increase of expansion in compressed air foam system,and the acetone fire is more difficult to extinguish than ethanol fire.It is necessary to evaluate the fire extinguishing performance according to the target water-soluble liquid when selecting alcohol-resistant foam.
