Aqueous film-forming foam fire extinguishing agent 6% AFFF、-10℃
Product name: AFFF 6% AFFF, -10℃
Specification model: 6%AFFF
First, basic functions:
Brief Description: 6% (AFFF, -10 ℃) foam fire extinguishing agent is an environmentally friendly, high quality water film-forming fire extinguishing agent that can extinguish hydrocarbon fuels in 6 volumes mixed with 94 volumes of fresh water Fire, suitable for 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; water produced by aqueous film-forming fire extinguishing agent can reduce the surface tension of foam solution because it contains fluorocarbon surfactant, which is related to fuel with high surface tension. , such as diesel and aviation gasoline, are somewhat more effective than lower surface tension fuels such as hexane and gasoline.
1. The fire extinguishing speed is fast and the fire resistance performance is good. The fire extinguishing level has been tested by the "National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center" as IA level.
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 together with compatible dry powder.
6. Storage time is 8 years.

Fourth, scope of use
AFFF6% aqueous film-forming foam fire extinguishing agent is used in fixed fire extinguishing system or mobile fire extinguishing device with corresponding mixing ratio, suitable for extinguishing hydrocarbon fires, such as gasoline, crude oil, diesel, heavy oil and other fires. Aqueous film-forming foam extinguishing agents are not suitable for polar or water-soluble fuels such as alcohols, ketones and esters.
