Abstract

The invention discloses a fine water mist additive and a preparation method and application thereof. The fine water mist additive consists of 2-10% of alkaline-earth metal salt, 2-30% of alkali metal salt, 0.5-10% of surface active agent and the balance of water, wherein the specific gravity of water solution is 1.1-1.2. The preparation of the fine water mist additive comprises the following steps: the alkaline-earth metal salt, the alkali metal salt and the surface active agent are dissolved in the water in sequence, and are stored in a sealed container. The fine water mist additive is applied to fight A and B types of fire, is diluted by the water, is filled in a fine water mist generator, and is sprayed to a fire filed for firefighting. The fine water mist fire extinguishing agent is strong in firefighting capacity on A and B types of fire, is quick in firefighting speed and high in firefighting efficiency, and is suitable for promotion 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 fire extinguishing, and the fire extinguishing efficiency of water is improved by using small (usually < 400 mm) fine water mist particles. 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...
