The main fire extinguishing function of halogenated hydrocarbon extinguishing agent is

Reduce ignition point, inhibit chemical chain reaction and insulation.

1, reduce the ignition point: halogenated hydrocarbon extinguishing agent can absorb the heat around the flame and reduce the temperature and ignition point of the fuel. By reducing the ignition point, the flammability of fuel can be reduced and the flame can be extinguished gradually.

2. Inhibition of chemical chain reaction: halogenated hydrocarbon extinguishing agent will interfere with the chemical chain reaction process in the flame. The combustion of flame is a self-sustaining process, which includes many complex chemical reactions. Halogenated hydrocarbon fire extinguishing agent can inhibit these reactions, prevent the flame from spreading and burning, and achieve the effect of fire extinguishing.

3. Insulation: Halogenated hydrocarbon fire extinguishing agent can form an insulating film on the surface of fuel to prevent oxygen in the air from entering the fuel and continue to support the combustion of flame. This kind of heat insulation can cut off the contact between the flame and oxygen, weaken the burning ability of the flame, and gradually extinguish the flame.
