Aqueous film-forming foam fire extinguishing agent 3% AFFF、-9℃
Product Name:Aqueous Film Forming Foam Fire Extinguishing Agent 3% AFFF, -9℃
Specification model: 3%AFFF
1. Basic functions:
Brief description: 3% AFFF, -9 ℃ foam fire extinguishing agent is an environmentally friendly, high quality water film-forming fire extinguishing agent, which can extinguish hydrocarbon fuel fires after mixing 3 volumes with 97 volumes of fresh water, suitable for Works with most proportioning mixers and foam injection units. Water film-forming fire extinguishing agent can form a water film on the fuel surface to isolate the water from the foam layer during the fire extinguishing process, and has excellent fluidity to quickly extinguish the fire by overwhelming the fire. At the same time, it has the advantages of long-term sealing performance and anti-flame back burn-back. Because it contains fluorocarbon surfactant, the water produced by aqueous film-forming fire extinguishing agent can reduce the surface tension of the foam solution, which is related to the fuel with high surface tension. Such as diesel and aviation gasoline, the effect is better than lower surface tension fuels 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.
