Abstract

The invention discloses a production method for improving hypochlorous acid solution stability and belongs to the technical field of hypochlorous acid solution production. In order to improve the stability of a hypochlorous acid solution and prolong the validity period of the hypochlorous acid solution, the invention provides the production method for improving the stability of the hypochlorous acid solution. The production method comprises the following steps: adding 10-50ppm of a regulator into domestic drinking water; introducing a diluted hydrochloric acid solution and the domestic drinking water added with the regulator into a diaphragm-free electrolytic cell in a hypochlorous acid generator through a pump body, and carrying out mixing and electrolysis to generate a hypochlorous acidinitial solution; adding 50-300 ppm of a stabilizer into the generated hypochlorous acid initial solution to generate the hypochlorous acid solution; wherein the effective content is 40-60 mg/L, the pH value is 5.0-7.0, and the residual chloride ions are less than 1000 mg/L. And in an opaque sealed container and under a dark condition, the product is placed in a thermotank at 54-57 DEG C for 14 days, the content of available chlorine is reduced by less than or equal to 10%, and the validity period of the product can be up to 1 year.

Description

technical field [0001] The invention relates to the technical field of production of hypochlorous acid solution, in particular to a production method for improving the stability of hypochlorous acid solution. Background technique [0002] Hypochlorous acid is a strong oxidizing disinfectant. Under the same concentration of available chlorine, the bactericidal ability of hypochlorous acid molecules is 80 times that of hypochlorite. It can not only act on the cell wall and virus shell, but also because the hypochlorous acid molecule is small and uncharged, it can pass through the cell wall and penetrate into the bacteria (virus) body to undergo oxidation reactions with bacteria (virus) body proteins, nucleic acids, enzymes, etc. Destroy the enzyme system of bacteria, hinder the metabolism of bacteria, and kill pathogenic microorganisms. The higher the concentration of hypochlorous acid in the solution, the stronger the bactericidal effect. [0003] Compared with the traditio...
