Description
Fire-fighting foam concentrate, aqueous film-forming foam fire extinguishing agent is also called light water foam fire extinguishing agent. Composed of fluorocarbon surfactants, fluorine-free surfactants (carbon-chlorinated surfactants or silicone surfactants) and additives to improve foam performance (foam stabilizers, antifreeze agents, co-solvents and thickeners, etc.) and water composition. According to the mixing ratio with water volume, there are two types: 3% AFFF (3:97) and 6% AFFF (6:94).
Main Features
AFFF fire extinguishing agents are low energy consumption, requiring only minimal agitation energy.
The foam produced has excellent fluidity and can quickly overwhelm the flames and put out oil fires.
The mixture of aqueous film-forming foam fire extinguishing agent and clear water or fresh water is suitable for fire extinguishing.
Compatible with most proportional mixing devices (foam tanks) and foam fire extinguishing devices.
AFFF fire extinguishing agents can be used in combination with compatible dry powder fire extinguishing agents.
Application
Anti-solvent water film-forming foam fire extinguishing agent is widely used to put out various types of Class B fires. The general fire extinguishing performance can be used to put out unknown or mixed Class B fuel fires with oil and polar solvents, and unleaded motor gasoline. fire. It is suitable for extinguishing large oil tank fires by means of "submerged jetting". It can be combined with dry powder fire extinguishing agents, and can be used together with most fire-fighting foam fire extinguishing agents in the fire extinguishing process.
The aqueous film-forming foam fire extinguishing agent has the advantages of good sealing performance, fast fluidity and high strength resistance to flame burnback. It is an excellent fire control and fire extinguishing agent for Class B fires. AFFF is also an excellent wetting and penetrating agent for class A fires. It can quickly extinguish deep flames in wood piles, paper, rubber and general combustibles. Widely used in oil fields, refineries, oil depots, ships, docks, airports, hangars, etc.
