适用范围
1、 适用于扑救绝大数的极性液体火灾。其灭火效率远
**金属皂型抗溶泡沫;
(5) 保管储存
环保型抗溶泡沫液腐蚀性较小,但长期储存时应考虑防腐问题,可储存在天硬钢、不锈钢或聚乙烯塑料容器中。储存温度为-4.5~400C,有效储存期4年。
在有效储存期内,应每隔一年进行一次全面质量检查。**过有效储存期的泡沫液应送有关单位检查,以确保能否继续使用。

B、应用范围
该灭火剂为低倍数泡沫灭火剂,适用于各种类型的低倍数泡沫产生器。水成膜泡沫灭火剂能与干粉联用,也可采用“液下喷射”的方式扑救大型油罐火灾,广泛适用于飞机场、油田、大型化工厂、化工仓库、油库、船舶、码头等处火灾的预防与扑救。
抗溶性水成膜泡沫灭火剂在满足水成膜泡沫灭火剂的适用范围基础上,还能适用于生产,储存醇、酯、醚、醛、酮**酸等水溶性可燃、易燃液体的化工厂、酒厂、化工仓库等。
The extinguishing agent is a kind of low expansion foam fire extinguishing agent, which is adapted to various low expansion foam generators. Aqueous film forming foam fire extinguishing agent (AFFF)can be used in combination with dry chemical and also can be used to extinguish large oil tank fire extinguishments in airport,oilfield,large chemical plant, chemical storehouse, oil depot and shipping etc.
Besides the application situation of Aqueous Film Forming Foam Fire Extinguishing Agent (AFFF),Alcohol Resistant Aqueous Film Forming Forming Fire Extinguishing Agent also can be used in chemical plant, winery and chemical storehouse, where water-solubility combustible and flammable liquids are produced or stored such as alcohol , ester ,ether, aldehyde, ketone and organic acid etc.

灭火原理
当环保型抗溶泡沫施加到水溶液体(极性液体)燃料表面时,触变性多糖与极性液体发生凝胶作用,形成一层不溶于极性液体秘上层泡沫隔开,阻止极性液体向上层泡沫的扩散和上层泡沫的继续凝聚,从而保证了在极性液体表面上形成一个连续的泡沫层,通过隔绝空气、抑制燃料蒸发、冷却等作用把火扑灭。
