Aqueous film forming foam extinguishing agent 3% AFFF, - 17 ℃

Describe

brief description: Environmentally friendly aqueous film-forming foam fire extinguishing agent 3% (AFFF) is a high-quality foam fire extinguishing agent, which can extinguish hydrocarbon fuel fires after mixing 3 volumes of fire extinguishing agent with 97 volumes of fresh water, Compatible with most proportioning mixers and foam injection devices. During the fire extinguishing process, the water released from the foam layer of the aqueous film-forming fire extinguishing agent can form a water film on the surface of the fuel to isolate it from contact with the air, and has excellent fluidity so that it can quickly overwhelm the fire and extinguish the fire. At the same time, it has the advantages of long-term sealing performance and flame back burning resistance; the water produced by the aqueous film-forming fire extinguishing agent contains fluorocarbon surfactants, which can reduce the surface tension of the foam solution and make it float on the surface of the fuel. The effectiveness of the water film is directly related to the surface tension of the fuel. For fuels with higher surface tension, such as diesel and aviation gasoline, the effect is better than that for fuels with lower surface tension (such as hexane and gasoline).

    Fourth, the scope of use

    Environmentally friendly aqueous film-forming foam fire extinguishing agent 3% is used in fixed fire extinguishing systems or mobile fire extinguishing systems with a mixing ratio of 3%. It is suitable for extinguishing hydrocarbon fires, such as: crude oil, gasoline, fuel oil and other fires, but the extreme Non-volatile solvents or water-soluble fuels, such as alcohols, ketones, esters, ethers and other flammable fires are not suitable. Typically used in foam/spray fire extinguishing systems and hangars, petroleum loading and unloading areas and processing areas, especially suitable for extinguishing airport fires and personnel rescue and places that do not contain polar solvent fires, and can also be used as a wetting agent to extinguish A class fire. In short, water-forming film-forming fire extinguishing agents can be applied to general fire-fighting nozzles and water spray equipment without suction devices, but in order to obtain the best foaming multiple and liquid analysis time, all fire extinguishing agents should be used with suction Device foam tube gun and foaming device.
