Aqueous film-forming foam fire extinguishing agent 3%AFFF、-17℃
Product Name: Aqueous Film Forming Foam Fire Extinguishing Agent 3%AFFF, -17℃
Brief Description: Environmentally Friendly Aqueous Film Forming Foam Fire Extinguishing Agent 3% (AFFF) is a high quality foam fire extinguishing agent that can extinguish hydrocarbon fuel fires after mixing 3 volumes of extinguishing agent with 97 volumes of fresh water, suitable for large Most proportioning mixers and foam injection devices. In the process of fire extinguishing, the water separated from the foam layer of the water film-forming fire extinguishing agent can form a water film on the fuel surface to isolate it from contact with the air, and has excellent fluidity to quickly overwhelm the fire and extinguish the fire. At the same time, it has the advantages of long-term sealing performance and anti-flame burnback; the water produced by the aqueous film-forming fire extinguishing agent contains fluorocarbon surfactant, 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 for fuels with lower surface tension (such as hexane and gasoline).
1. The fire extinguishing speed is fast, the fire resistance is energy consumption, and the fire extinguishing level has been tested as IA level by the "National Fixed Fire Extinguishing System and Refractory Component Quality Dudu Testing Center".
2. Low energy consumption AFFF, requiring minimal stirring energy.
3. With excellent fluidity, it can quickly overwhelm the flame to extinguish oil fires.
4. Standard foam proportioning mixers and other foaming devices can be used.
5. Can be used with compatible dry powder.
6. Storage time is 8 years.

Fourth, scope of use
Environment-friendly water film-forming foam fire extinguishing agent 3% is used in fixed fire extinguishing system or mobile fire extinguishing system with a mixing ratio of 3%, suitable for extinguishing hydrocarbon fires, such as: crude oil, gasoline, fuel oil and other fires, However, it is not suitable for fires with polar solvents or water-soluble fuels, such as alcohols, ketones, esters, ethers and other flammable fuels. It is typically used in foam/sprinkler systems, hangars, oil loading and unloading areas and processing areas. class fire. In short, water film-forming fire extinguishing agents can be used in general fire water guns and water spray equipment without suction devices, but in order to obtain the best foaming ratio and liquid elution time, all fire extinguishing agents should be used with suction. The device's foam tube gun and foaming device.
