Fluoroprotein foam fire extinguishing agent is made by adding appropriate fluorocarbon surfactant on the basis of protein foam fire extinguishing agent. Due to the effect of fluorocarbon surfactant, it has the advantages of low surface tension, low critical shear stress and strong oleophobic ability.

Tank fire can be extinguished by underwater spraying; it has unique oil repellent ability, good fluidity and strong self-sealing ability. In fact, fluoroprotein foam fire extinguishing agent is a kind of protein foam fire extinguishing agent, which is prepared on the basis of protein foam fire extinguishing agent on the basis of adding suitable fluorocarbon surfactant. Fluoroprotein foam liquid has good fluidity after adding fluorocarbon surfactant, and it is not easy to defoam in oil. Fluoroprotein foam liquid not only has the fire extinguishing performance of protein foam extinguishing agent, but also can be used to extinguish the fire by "liquid injection" method. Clearing fires in large oil storage tanks is the mainstream extinguishing agent that can protect large oil tanks. It can also be used in combination with a dry powder extinguishing agent, which is three times faster than a protein foam extinguishing agent.

Fluoroprotein foam fire extinguishing agent is a low-expansion foam fire extinguishing agent. It is mixed with water according to the ratio of 3:97 or 6:94 in various low-expansion foam generating equipment to generate foam. It is used for fire fighting and prevention of non-water-soluble flammable and flammable liquid and carbon-containing solid fire. The fire extinguishing effect is better than that of protein foam fire extinguishing agent.

Compared with protein foam fire extinguishing agent, fluorine protein foam fire extinguishing agent has obvious characteristics:

1. The surface tension and interfacial tension are significantly reduced;

2. The foam has good fluidity and fast fire extinguishing speed;

3. Fluorine protein foam anti-oil ability, liquid spraying can put out large oil tank fire.

4. can be used with dry powder.

Fluoroprotein foam fire extinguishing agent is composed of hydrolyzed protein, fluorocarbon surfactant, hydrocarbon surfactant, solvent and antifreeze.

(1) Hydrolyzed protein: It is the main foaming agent of fluorine protein foam extinguishing agent, with good foaming ability, excellent foam stability and heat resistance.

(2) Fluorocarbon surfactant is the main synergist of fluoroprotein foam fire extinguishing agent. The main function is to further reduce the surface tension of the mixed solution, improve the fluidity of the foam, oleophobic ability and resistance to dry powder damage.

(3) Hydrocarbon surfactants: The role of hydrocarbon surfactants is to assist in changing the fire extinguishing performance of protein foams.

Due to the effect of fluorocarbon surfactant, there is a layer of fluorocarbon surfactant oriented adsorption layer formed at the junction of fluorocarbon foam and fuel surface, which controls the evaporation of fuel and makes fluorocarbon foam have better fluidity and fire extinguishing performance.

Protein, fluorine protein foam fire extinguishing agent is mainly used for the general non-water soluble flammable and combustible liquid fire fighting and prevention, fluorine protein foam fire extinguishing agent can be combined with dry powder, can also be used in the "liquid spray" way to fight the large oil tank fire.
