Purpose and use method of water-based fire extinguisher

On the one hand, water mist is produced because it can absorb a lot of heat and quickly reduce the temperature of the fire site; On the other hand, surfactant rapidly expands into an uninterrupted water film on the surface of combustible materials to isolate oxygen and achieve the purpose of suffocation and fire extinguishing. It also has a strong permeability, which can penetrate into the interior of combustible materials and play a role of impact resistance and anti-re-combustion. Because of its good paving performance, water mist is particularly suitable for extinguishing the spontaneous combustion in the engine hood of automobiles. The normal dry powder fire extinguisher needs to open the engine hood to find the burning point in order to eject fuel, but this process may cause explosion. In addition, the water-based fire extinguisher can be sprayed directly from the gap without opening the cover, and the water mist will spread automatically, which can play a role in extinguishing fire. Because water-based fire extinguishers have good sterilization effect, they can kill people's face and body in an emergency as a bactericidal measure in densely populated places. Although the traditional dry powder fire extinguisher can extinguish the fire, once the place where it is extinguished has another fire, it will be re-burned immediately. Moreover, water-based fire extinguishers have excellent resistance to re-ignition, and the place where they are sprayed cannot be ignited again. Therefore, in addition to direct fire extinguishing, it can also spray around the fire site in advance to prevent the spread of the fire.
