Basic Knowledge Of Water Mist Fire Extinguisher

Water base type Fire extinguisher its fire extinguisher mechanism is the principle of physical fire extinguisher. The main agents are hydrocarbon surfactants, fluorocarbon surfactants, flame retardants and additives composition, water-based (water mist) fire extinguisher after spraying, mist-like, the instantaneous evaporation of the fire a lot of heat, quickly reduce the temperature of the fire, inhibit thermal radiation, surfactant on the surface of combustible materials to form a layer of water membrane, isolation of oxygen, cooling, isolation dual role, and participate in fire extinguishing, so as to achieve the goal of rapid fire. Fire extinguishing agent on a class of the role of infiltration, such as wood, cloth and so on, extinguishing agent can penetrate combustible materials inside, even if the fire is not all extinguished, its agent injection parts can effectively block the ignition, to control the spreading speed of fire, and the effect of isolating the Class B fire, such as petrol and volatile chemical liquids, the medicament can form a long water film on its surface, even if the water film is damaged by external factors, its unique fluidity can heal quickly and suffocate the flames. So water-based (water mist) fire extinguishers with other fire extinguishers can not be comparable to the flame-retardant. Water-based fire extinguishers are not affected by indoor, outdoor, gale and other environment, the fire extinguishing agent can be the maximum effect on the surface of the combustion.
