Problems solved by technology

[0007] Common chlorine dioxide disinfection products currently on the market have many deficiencies such as few effective days for disinfection, high product prices, and strong odor, and the preparation of long-acting chlorine dioxide sustained-release agents is complicated, high in price, poor in release effect, and commercialized. Difficult, the release effect of the chlorine dioxide antibacterial film is not good, the productization is difficult, and it is not easy to carry, and when the ordinary chlorine dioxide slow-release gel is opened, a large amount of chlorine dioxide gas escapes, the release time is short, and the release amount decreases day by day

Abstract

The invention discloses a chlorine dioxide reaction type slow-release disinfection device which is characterized in that reactant gel and activator gel are mixed according to the volume ratio of (1-3): 2, and the reactant gel is prepared from the following components in parts by weight: 40-60 parts of a sodium chlorite aqueous solution, 4-6 parts of sodium chloride, 1-3 parts of gel and 40-60 parts of water; the activating agent gel is prepared from the following components in parts by weight: 10 to 14 parts of acidic substances, 25 to 30 parts of gel, 4 to 6 parts of 2H-sodium carboxymethyl cellulose and 70 to 90 parts of water. According to the method provided by the invention, the release effect of the chlorine dioxide is good, the chlorine dioxide can be released for 30 days, and the method has the advantage of relatively uniform early-stage release.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, in particular to a chlorine dioxide reaction type slow-release disinfection device. Background technique [0002] Chlorine dioxide is recognized as a new generation of high-efficiency, broad-spectrum, safe bactericidal and fresh-keeping agent, and is the most ideal substitute for chlorine preparations. It has been widely used at present. [0003] There are currently theoretical studies on the sustained release of chlorine dioxide binary solids. [0004] Chlorine dioxide antibacterial film: use non-woven fabric as the carrier of the reaction component, use polyvinyl alcohol to coat sodium chlorite component A and β-cyclodextrin-coated acid combination B to make films respectively, and develop Chlorine dioxide antibacterial fresh-keeping film with slow-release function. [0005] Chlorine dioxide long-acting sustained-release agent: when sodium carboxymethylcellulose (CMC) is selected as the...
