在受限空间内使用含十二烷基苯磺酸钠添加剂和纯细水雾进行灭固体火的对比实验,通过灭火时间、火焰温度分布对不同浓度添加剂细水雾熄灭油池火的机理和有效性进行了分析。实验研究表明:含有十二烷基苯磺酸钠的细水雾比纯细水雾有更好的抑制效果,细水雾的灭火时间并不是随着添加剂的浓度变化而呈线性变化的,添加剂浓度为0.4%时,对细水雾灭火性能的提高效果最好。当浓度超过这一值时,表面张力维持在一恒定值,细水雾的灭火性能也不会有明显提升。 In a confined space using sodium dodecyl benzene sulfonate additives and pure water mist to extinguish solid fire comparative experiment, through the fire extinguishing time, the flame temperature distribution of different concentrations of additive mist to extinguish the pool fire mechanism and The effectiveness is analyzed. Experimental studies have shown that fine water mist containing sodium dodecyl benzene sulfonate has a better inhibiting effect than pure water mist. The extinguishing time of water mist does not change linearly with the concentration of the additive. Additives Concentration of 0.4%, the best water mist fire performance improvement. When the concentration exceeds this value, the surface tension is maintained at a constant value, the water mist performance will not be significantly improved.
