AFFF Fire Foam Liquid is a foam extinguishing agent, which is a foam formed by mixing water with a defoamer to extinguish liquid fires.
This defoamer is usually a mixture of surfactant and blowing agent that is able to form a stable foam in water.
The application of fire-fighting foam liquid in fire-fighting work mainly has the following characteristics and advantages:
1. Inhibition of flames: fire-fighting foam liquid can effectively inhibit the combustion of flames, and weaken the heat and oxygen of the flame through the covering and inhibition of foam, so as to achieve the purpose of extinguishing fires.
2. Covering the surface of the liquid: The foam liquid can form a stable layer of foam to cover the surface of the liquid, prevent the liquid from coming into contact with the air, reduce the release of vapor, and effectively control the spread of fire.
3. Oxygen isolation: The foam liquid foam contains a large number of bubbles, which can effectively isolate the flame from the oxygen from the outside world, prevent the further combustion of the flame, and thus curb the spread of the fire.
4. Prevent fire re-ignition: The foam liquid can form a protective film to cover the surface of the liquid to prevent the flame from re-ignition, keep the fire in a state of ignition, and provide long-term protection.
To sum up, as a foam fire extinguishing agent, AFFF fire foam liquid plays an important role in firefighting work, which can effectively extinguish liquid fires and protect personnel and property safety.
