First of all, introduce some knowledge about the composition of fluorine protein foam fire extinguishing agent. Fluoroprotein foam fire extinguishing agent includes: acidic salt (aluminum sulfate), alkaline salt (sodium bicarbonate), foaming agent (plant hydrolyzed protein or licorice powder), stabilizer (ferric chloride) and fluorocarbon surfactant. When ordinary protein foam passes through the oil layer, due to its inability to resist oil stains, the oil contained in the foam itself rises to the oil surface and is sufficient to burn it, resulting in foam destruction. Fluorocarbon surfactant is added to the bubble liquid to form fluorine protein foam. Then, let's learn about the knowledge points and functions of fluorine protein foam extinguishing agent!

Fluorocarbon surfactants have good surface activity, high thermal stability, good wettability and fluidity. When the foam passes through the oil layer, the oil cannot diffuse into the foam and is separated into small oil droplets by the foam. These small oil droplets are wrapped by uncontaminated foam to form a non-combustible foam layer. There are small oil droplets on the surface of the oil layer. Even if the gasoline content in the foam is as high as 25%, it will not burn, while the ordinary air foam layer contains 10% gasoline. It will start to burn. Therefore, this fluoroprotein foam extinguishing agent is suitable for oil fire extinguishing with higher temperature, and it is also suitable for liquid jet fire extinguishing.

Fluoroprotein foam fire extinguishing agent is a new type of foam fire extinguishing agent made by adding appropriate amount of fluorocarbon surfactant to the protein foam fire extinguishing agent. The fire extinguishing agent has unique oil repellent ability, good fluidity and strong self-sealing ability. It can be used in conjunction with dry powder fire extinguishing agent, and its fire extinguishing efficiency is 2 times that of protein foam fire extinguishing agent. Applicable fire scope with protein foam fire extinguishing agent. 3% FP(3:97), 6% FP(6:94) by volume mixed with fresh water or sea water.

Fluorine protein foam fire extinguishing agent fire extinguishing principle:

Fluoroprotein foam fire extinguishing agent is a low-expansion foam fire extinguishing agent, which is suitable for various low-expansion foam generators. Foam is produced under the action of mechanical external force. A layer of polymer film is formed at the interface between fuel and foam. Relying on the dual role of film and foam, the foam is effectively protected from the destruction of polar liquid. It quickly and effectively isolates the air and suffocates the fire.

When ordinary protein foam passes through the oil layer, because it cannot resist oil pollution, the oil contained in the foam itself rises to the oil surface and is sufficient to burn it, resulting in the destruction of the foam. Fluoroprotein foam is formed by adding fluorocarbon surfactant to the bubble solution. Fluorocarbon surfactants have good surface activity, high thermal stability, good wettability and fluidity.

Fluoroprotein foam fire extinguishing agent is a low-expansion foam fire extinguishing agent made of protein foam as the base material, adding a small amount of fluorocarbon and hydrocarbon surfactant. Due to the addition of fluorocarbon surfactants, the surface tension and interfacial tension of the foam premix are greatly reduced, and the oleophobic ability of the protein foam is improved, which can be applied to the immersion spraying technology of oil storage tanks.

Fluoroprotein foam fire extinguishing agent is the same as protein foam fire extinguishing agent, which is mainly used to put out various non-water soluble combustible, flammable liquid and partially combustible solid fires. Widely used in large storage tanks (underwater injection), bulk warehouses, transport transfer devices, production and processing devices, oil terminals, aircraft fire fighting. It is mainly used for fighting fires caused by water-insoluble substances such as petroleum and petroleum products. It is widely used in large chemical enterprises, oil fields, oil depots, ships, hangars and other fixed fire extinguishing devices. It can also be used for mobile fire extinguishing equipment such as fire engines to extinguish large-scale oil fires and solid fires.
