Abstract

The invention discloses a fine water mist additive and its preparation method and application. It consists of 2-10% of alkaline earth metal salt, 2-30% of alkali metal salt, 0.5-10% of surfactant and the rest of water , the specific gravity of its aqueous solution is 1.1~1.2. The preparation of the fine water mist additive comprises the following steps: dissolving the alkaline earth metal salt, the alkali metal salt and the surfactant in water according to the ratio, and storing them in a sealed container. The fine water mist additive of the present invention is applied to fire fighting of Class A and B fires. The fine water mist additive is diluted with water, filled into a fine water mist generator, and sprayed to the fire field for fire extinguishing. The fine water mist fire extinguishing agent of the present invention has strong fire extinguishing ability for both types of AB fires, has high fire extinguishing speed and high fire extinguishing efficiency, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the field of fire extinguisher additives, in particular to a fine water mist additive and its preparation method and application. Background technique [0002] Water mist fire extinguishing technology has the characteristics of environmental protection, no pollution, rapid fire extinguishing, high fire extinguishing efficiency, less damage to protected objects, and can be used for Class E electrical live fires. It can be widely used in various fire protection fields in national production and life. [0003] The traditional water mist fire extinguishing technology mainly relies on physical action to extinguish fire, and uses small (usually <400mm) fine water mist particles to improve the fire extinguishing efficiency of water. First of all, the evaporation speed of fine water mist is fast, and the evaporation efficiency is very high. The latent heat of vaporization absorbed during the evaporation process effectively cools the...
