Aqueous film-forming foam fire extinguishing agent (also known as light water foam fire extinguishing agent) is composed of hydrocarbon surfactants, fluorocarbon surfactants, additives, stabilizers, antifreeze, etc. It is an efficient foam fire extinguishing agent. Other features are that a protective film can be formed on the surface of the oil to inhibit the evaporation of the oil. Relying on the dual action of the foam and the protective film, it has high fire extinguishing efficiency, fast speed, and anti-reburn performance Good sealing performance, high pollution resistance and long storage period.
After the aqueous film-forming foam fire extinguishing agent is mixed with water through a foam ratio mixing device, the output foam mixture is produced by foam generating spray equipment (foam generator, foam generator, foam nozzle) to produce fire extinguishing foam, and when sprayed to the burning oil surface, The water produced by the foam chromatography can form a well-sealed water film on the surface of the fuel, which can isolate the contact between the fuel and the air.The dual functions of the foam and the protective film can quickly and efficiently extinguish oil fires.
The aqueous film-forming foam fire extinguishing agent is low energy consumption and requires only a small amount of stirring energy. The foam produced is fluid and can quickly overwhelm the flame to extinguish oil fires. The mixture of aqueous film-forming foam fire extinguishing agent, clean water and fresh water is suitable for fire extinguishing . Compatible with most ratio mixing devices (foam tanks) and foam fire extinguishing devices. Aqueous film-forming foam fire extinguishing agents can be combined with compatible dry powder fire extinguishing agents.
The aqueous film-forming foam fire extinguishing agent has the advantages of good sealing performance, fast fluidity and high-strength anti-flame back-burning. It is the control and fire extinguishing agent for class B fires. In the extinguishing of class A fires, the aqueous film-forming foam extinguishing agent is also humid It is also a penetrant. It can quickly extinguish deep flames in wood piles, paper, rubber and usually combustibles. It is widely used in oil fields, refineries, oil depots, ships, docks, airports, hangars, etc.
