Type water-based fire extinguishers fire extinguisher mechanism for physical principle of fire extinguisher.Fire extinguishing agent are mainly hydrocarbon surfactants and fluorocarbon surfactants, flame retardants and additives.Water type fire extinguisher after injection, water mist shape, evaporating fire a lot of heat, quickly lower the temperature in the fire, inhibition of thermal radiation, surface active agent in the fuel surface rapidly form a layer of water film, oxygen isolation, cooling, isolation dual function, at the same time to participate in the fire, so as to achieve the purpose of rapid fire.
