What is Fluorin foam extinguishing agent? What are the characteristics?

When the ordinary protein foam passes through the oil layer, it cannot withstand the pollution of the oil, and the oil contained in the foam itself is enough to make it burn after being raised to the oil surface, resulting in the destruction of the foam. Adding a fluorocarbon surfactant to the air foam solution generates fluoro-protein foam.

Fluorocarbon surfactants have good surface activity, high thermal stability, good wettability and flowability. When the foam passes through the oil layer, the oil cannot diffuse into the foam and is divided into small oil droplets by the foam. The small oil droplets are surrounded by uncontaminated foam and form an incombustible foam layer with small oil droplets on the surface of the oil layer. Even if the foam contains up to 25% gasoline, it will not burn, while the ordinary air foam layer contains 10 % of gasoline begins to burn. Therefore, this fluorinated protein foam fire extinguishing agent is suitable for extinguishing oils at higher temperatures and is suitable for submerged firefighting.
