Abstract

The invention discloses a preparation method of hypochlorous acid disinfectant fluid. The method comprises the following steps: S1, preparing a preparation instrument: preparing a diaphragm-free electrolysis device, wherein the device is composed of a filter, an air bag, a stock solution pump, a gas separator and an electrolytic cell, hydrogen generated in the electrolytic cell is discharged outdoors through the gas separator, and the electrolytic cell is composed of a separation plate, filler, a cathode plate, a gasket and an anode plate in sequence; S2, providing the following electrolysis conditions: a titanium plate coated with a PdO series is taken as an anode and a 316 stainless steel plate as a cathode in each of three unit cells of the electrolytic cell, the room temperature is 20-25 DEG C, the circulating electrolysis water amount is 0.05-1 m<3>, the interelectrode flow rate is 80-100 cm / s, and the interelectrode distance is 0.5-0.9 mm; S3, preparing electrolyzed water; S4, adjusting the pH value; S5, preparing a neutralizer; and S6, mixing. The disinfectant fluid is harmless to a human body and can be used for external sterilization; by adding the neutralizer, the sterilization effect is good, sterilization substances are stable; and the whole preparation process is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of disinfectant water, in particular to a preparation process of hypochlorous acid disinfectant water. Background technique [0002] Slightly acidic hypochlorous acid water is colorless and odorless electrolyzed water with a pH value of 5.0-6.5, high bactericidal effect, also known as slightly acidic electrolyzed water (SAEW for short), slightly acidic oxidation potential water. In the food field, compared with sodium hypochlorite or alcohol sterilizers that are currently widely used, it can ensure safety, reduce costs, and reduce environmental load. [0003] The production cost of present hypochlorous acid disinfection water is higher, and operation is more loaded down with trivial details, and bactericidal efficiency is at 60-70%, so need a kind of preparation technology of efficient, stable, good hypochlorous acid disinfection water. Contents of the invention [0004] The purpose of the invention is in...
