摘要
通过汽油油盆火实验,研究了几种环保型表面活性剂的组成和结构对其作为细水雾添加剂时对细水雾灭火性能的影响。结果表明,以含氮非离子表面活性剂为添加剂所配制的细水雾具有良好的灭火性能;含氮非离子表面活性剂的EO数和烷基烃链的含碳数对细水雾的灭火与降温性能有影响;以含氮非离子表面活性剂为主组分进行复配所得的细水雾添加剂体系的表面张力越低,其细水雾的降温性能越强。
Through the experiments of extinguishing the gasoline fire in a basin,the effects of the compositions and structures of several surfactants,when used as the water-mist additives,on the performance of water-mist fire extinguishing have been studied.The experimental results revealed that the water-mist containing non-ionic surfactant with nitrogen element has better fire extinguishing performance;the EO numbers and carbon numbers of the alkyl hydrocarbon chain of non-ionic surfactant with nitrogen element have effects on the performances of fire extinguishing and temperature decreasing;when adopt the non-ionic surfactant with nitrogen element as the main component in the mixed additives,the lower the surface tension of the mixed additives,the better the decreasing temperature performance of the water-mist containing the mixed additives.
