Additive for water-mist fire suppression

Present fine water mist additives, wherein the total mass of the solution is 3.0 to 6.0% fluorine surfactant, 67.5 - 80.2% of the total mass of the aqueous solution, accounting for 0.3 to 0.5% by mass of the total solution of triethanolamine, 4.0 ~ 6.5% urea and 1.0 to 1.5% of sodium lactate, 1.5 to 3.0% of an alkylphenol polyoxyethylene ether solution was added to account for the total mass of 10.0 to 15.0% in NN- dimethylformamide, or completely dissolved with acetic acid sodium hydroxide to adjust the pH to 7.5 to 8.5, the solution is the filtered water mist fire-extinguishing additives according to the present invention a concentrated solution; diluted with water when used, the content of fluorine surface active agent to which is reduced to 0.2 to 0.8%. Present fine water mist additives configuration process is simple; high extinguishing efficiency, the field of storage devices and fire extinguishing equipment without metal corrosion, pollution of the fire site; can be widely applied water mist system for all occasions.
