AFFF3、AFFF6型水成膜泡沫灭火剂
AFFF3, AFFF6 aqueous film-forming foam concentrates
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。
Aqueous film-forming foam concentrates (also called light water foam concentrates) is made up of hydrocarbon surface active agent, fluocarbon surface active agent, auxiliary agent, stabilizing agent, antifreeze agent, etc. It is a highly efficient foam extinguishing agent, which forms a protecting film on oil surface to inhibit the evaporation of oil and relies on the double action of foam and protecting film. It is characterized with high efficiency in fire extinguishing, excellent performance in preventing after burning and long time storage. The extinguishing agent is mixed with water in the proportion of 3:97 or 6:94. It can foam in low multiplying foam production equipment for extinguishing fire of oils. It may also be used together with powder extinguishing agent, and may also be used to extinguishing fire of oil storage cans in the manner of subsurface injection. It is widely used in oil field, refinery, oil depot, ships, ports, airports, machine warehouse, 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。
The extinguishing agent shall be sealed and kept at a cool、 dry and well-ventilated place with the ambient temperature between -5℃~40℃. The storage period is between 8 and 10 years.
