摘　　要：为了预防变压器火灾事故,采用短链氟碳表面活性剂FS-50分别与非离子(烷基糖苷(APG)-0810)、两性离子(椰油两性咪唑啉(CAD)-40)及阴离子(十二烷基硫酸钠(SDS))等表面活性剂复配,制备APG-0810/FS-50、CAD-40/FS-50、SDS/FS-50等3种泡沫溶液,并系统地分析变压器油存在下,泡沫溶液基本性质、起泡性、泡沫及液膜稳定性。结果表明:变压器油对泡沫性能影响显著。油的作用下,泡沫溶液的起泡性显著降低,APG-0810/FS-50、CAD-40/FS-50和SDS/FS-50的起泡性分别减少16.9%、18.4%、18.8%。油的作用下,泡沫析液加快,60 min析液量分别增加13.6%、74.6%和15.5%;泡沫体积衰减增加2.5%、9.8%和17.9%;液膜稳定性下降,100 s时膜厚分别下降276.5、414.7和552.9 nm。3种泡沫溶液中,APG-0810/FS-50复配体系对变压器油的抑制能力最好,该体系稳定的泡沫对变压器油的耐油性最佳。In order to prevent transformer fire accidents,short-chain fluorocarbons(FS-50)were combined with non-ionic(Alkyl Polyglucoside(APG)-0810),zwitterionic(Disodium Cocoamphodiacetate(CAD)-40)and anionic(Sodium Dodecyl Sulfate(SDS))three kinds of foam solutions,APG-0810/FS-50,CAD-40/FS-50 and SDS/FS-50 were prepared.The basic properties,foamability,foam and liquid film stability of the foam solution in the presence of transformer oil were systematically studied.The curves of foam drainage,volume decay,oil volume and film thickness were obtained over time.The results show that oil has a significant influence on foam properties.Under the action of transformer oil,the foaming ability of the foam solutions decreased significantly,and the foaming ability of APG-0810/FS-50,CAD-40/FS-50 and SDS/FS-50 were reduced by 16.9%,18.4%and 18.8%respectively.The volume of drainage in 60 min increased by 13.6%,74.6%and 15.5%,respectively.Foam volume decay increased by 2.5%,9.8%and 17.9%;The stability of liquid film decreased,and the film thickness decreased by 276.5,414.7 and 552.9 nm,respectively,at 100 s.Among the three foam solutions,the mixture of APG-0810/FS-50 has the best inhibition ability to transformer oil,and the stable foam of this system has the best oil resistance to transformer oil.The research results of this paper can provide a theoretical basis for the development and selection of special extinguishing agent for transformer oil fire.
