AFFF3、AFFF6型水成膜泡沫灭火剂AFFF3,AFFF6aqueousfilm-formingfoamconcentrates水成膜泡沫灭火剂（也称轻水泡沫灭火剂）由碳氢表面活性剂、氟碳表面活性剂、助剂、稳定剂、抗冻剂等组成。它是一种***泡沫灭火剂，其特点是在油类表面上能形成一层***油类蒸发的防护膜，靠泡沫和防护膜的双重作用，灭火效率高、速度快、防复燃性能和封闭性能好，贮存期长。该灭火剂与水按3：97或6：94的比例混合，可以在各种低倍数泡沫产生设备中发泡，扑救油类火灾；可以与干粉灭火剂联用灭火，亦可采用“液下喷射”的方式扑救大型油类贮罐火灾。广泛适用于油田、炼油厂、油库、船舶、码头，飞机场、机库等。Aqueousfilm-formingfoamconcentrates(alsocalledlightwaterfoamconcentrates)ismadeupofhydrocarbonsurfaceactiveagent,fluocarbonsurfaceactiveagent,auxiliaryagent,stabilizingagent,antifreezeagent,etc.Itisahighlyefficientfoamextinguishingagent,whichformsaprotectingfilmonoilsurfacetoinhibittheevaporationofoilandreliesonthedoubleactionoffoamandprotectingfilm.Itischaracterizedwithhighefficiencyinfireextinguishing,excellentperformanceinpreventingafterburningandlongtimestorage.Theextinguishingagentismixedwithwaterintheproportionof3:97or6:94.Itcanfoaminlowmultiplyingfoamproductionequipmentforextinguishingfireofoils.Itmayalsobeusedtogetherwithpowderextinguishingagent,andmayalsobeusedtoextinguishingfireofoilstoragecansinthemannerofsubsurfaceinjection.Itiswidelyusedinoilfield,refinery,oildepot,ships,ports,airports,machinewarehouse,etc.该灭火剂应密封存放在阴凉、干燥、通风、温度为0-40℃的环境中，贮存期八至十年。Theextinguishingagentshallbesealedandkeptatacool、dryandwell-ventilatedplacewiththeambienttemperaturebetween-5℃~40℃.Thestorageperiodisbetween8and10years.)
