Description
Technical Field
The utility model belongs to the technical field of hypochlorous acid preparation, and particularly relates to a hypochlorous acid preparation system.
Background
The hypochlorous acid mouthwash has the main component of hypochlorous acid molecules, good biological safety and strong bactericidal effect on various microorganisms such as bacteria, viruses and the like. The related studies show that: (1) When the effective chlorine concentration is 7.5ppm-15ppm, hypochlorous acid has better bactericidal effect on helicobacter pylori; when the effective chlorine concentration is more than 3.75ppm, hypochlorous acid has a good antibacterial effect on helicobacter pylori; (2) When the effective chlorine concentration is more than 0.938ppm, hypochlorous acid has good inhibition effect on helicobacter pylori biomembrane; (3) When the effective chlorine concentration is less than 15ppm, hypochlorous acid does not show cytotoxicity, and has higher safety.
However, the stability of hypochlorous acid solutions is closely related to the available chlorine content of the solution, the stabilizer component and its concentration, and the packaging materials of the storage tanks. Hypochlorous acid solutions have relatively good product stability with an effective chlorine content in the range of 50-300mg/L, and are unstable at lower or higher levels, and in particular, are easier to decompose, so hypochlorous acid products with an effective chlorine content of less than 30mg/L are rarely seen internationally. This is mainly because the valence of chlorine ions of hypochlorous acid is in an unstable state, and reduction reaction or oxidation reaction (normalization reaction or disproportionation reaction) is liable to occur, which is also the root cause of hypochlorous acid instability.
In the prior art, when the hypochlorous acid mouthwash is prepared, the hypochlorous acid solution with higher concentration is obtained by electrolysis of electrolysis equipment, then the hypochlorous acid solution with higher concentration is taken out, pure water is added for dilution, and a stabilizer is added for preparing the hypochlorous acid mouthwash, however, the hypochlorous acid is continuously lost in the preparation process due to the instability of the hypochlorous acid solution with higher concentration.
