Are Water-based Fire Extinguishers The Same As Foam Fire Extinguishers?

Water-based fire extinguishers and foam fire extinguishers are not the same

Foam fire extinguishers are mixed with sodium bicarbonate and aluminum sulfate to produce a large amount of carbon dioxide foam, which plays a role in heat insulation, air isolation and cooling.

The water-based fire extinguisher uses water mist containing surfactants, covering the surface of the flame, diffusing and penetrating into the surface of the combustion material, and playing the purpose of heat insulation, flame retardant, cooling and air isolation.

Foam fire extinguishers use chemical principles to generate new substances and produce chemical reactions.

Water-based fire extinguishers use the physicochemical principle that no new substances are created and no chemical reactions occur.

Fire extinguishers are divided from the composition, and there is little difference from the application, which is still dry powder fire extinguishers, foam fire extinguishers, carbon dioxide fire extinguishers, water-based fire extinguishers, etc.
