Fluoroprotein foam fire extinguishing agent is made by adding appropriate fluorocarbon surfactant on the basis of protein foam fire extinguishing agent. Fluoroprotein foam fire extinguishing agent can be sprayed under the liquid to extinguish the fire of large oil storage tank. General oil storage tanks are relatively high, large amount of oil. After the explosion and fire, the fire is fierce, the temperature is high, the radiation heat is strong, it is easy to spread and expand, and even continuous explosion, boiling overflow splash, tank deformation and collapse, etc. It makes it difficult for people, vehicles and equipment to get close to the battle, so it is very difficult and dangerous to put out the fire. In this case, the foam fire extinguishing system laid on the oil tank plays a vital role in controlling the initial fire and preventing the spread of the fire. Due to the high combustion temperature of the oil tank fire, the liquid upper jet fire extinguishing system is easily damaged, and the liquid lower jet fire extinguishing system is safer and more reliable.

Principle of Fluoroprotein Foam Fire Extinguishing Agent

It is mainly cooling and suffocation, that is, a continuous foam layer is formed on the surface of the burning substance, the surface of the burning substance is cooled by the mixture of the foam itself and the precipitation, and the burning substance is isolated from oxygen by the covering effect of the foam layer, thereby extinguishing the fire. The foam covering layer formed by the foam of the combustible surface can isolate the combustible surface from the air. The foam layer closes the surface of the combustion product, which can block the heat radiation of the flame to the combustion product, prevent the combustion product from evaporating or pyrolyzing volatilizing, and the combustible gas is difficult to enter the combustion zone. The liquid coming out of the foam has a cooling effect on the surface; the water vapor produced by evaporation can dilute the oxygen concentration in the combustion zone.

Fluoroprotein foam fire extinguishing agent is made by adding appropriate fluorocarbon surface on the basis of protein foam fire extinguishing agent. The fire extinguishing agent is a low-expansion foam fire extinguishing agent, which is suitable for various types of low-expansion foam generators. A layer of polymer film can be formed on the surface of the burning object, which can quickly and effectively isolate the air and suffocate the fire through the dual role of foam and film.

Protein and fluoroprotein foam fire extinguishing agents are mainly used to extinguish and prevent the initial fire of flammable and combustible liquids that are generally insoluble in water. It can be used in conjunction with dry powder, and can also be used to extinguish the initial fire of large oil tanks by means of "spraying under liquid.

Application Scope of Fluoroprotein Foam Fire Extinguishing Agent

Fluoroprotein foam fire extinguishing agent is a low-expansion foam fire extinguishing agent made of a small amount of fluorocarbon and hydrocarbon surfactant. Due to the addition of fluorocarbon surfactant, the surface tension and interfacial tension of the foam premix are greatly reduced, and the oil repellent ability of the protein foam is improved, and the large area oil tank fire can be extinguished by underwater spray.

Mainly used to put out a variety of water insoluble flammable, flammable liquids and some combustible solid fire. Widely used in large storage tanks (submerged jet), bulk warehouses, transport transfer devices, production and processing devices, oil terminals, aircraft and other places of fire fighting.
