Production formula for neutral chlorine dioxide powder (unitary package)

Abstract

A disclosed production formula for a neutral chlorine dioxide powder (unitary package) contains: (1) 10-50% of a main agent (sodium chlorite); (2) 1-20% of an activator (citric acid, tartrate, boric acid and sodium bisulfate); (3) 2-30% of an activation auxiliary agent (sodium dichloroisocyanurate and sodium trichloroisocyanurate); and (4) 5-50% of an additive (sodium sulfate and sodium chloride); and (5) 10-40% of an assistant agent (anhydrous magnesium sulfate). The chlorine dioxide powder with different contents and different packaged forms can be prepared by physical mixing. When the chlorine dioxide powder is directly dissolved or diluted into a solution with a chlorine dioxide concentration of 200-250 mg / L, the pH value of the solution is closes to 7, and the solution is neutral. The technology of the invention does not belong to the prior art, and has great breakthrough and improvement on the prior art. The technology helps to creatively make up the disadvantage that conventional solutions with a chlorine dioxide concentration of 200-250 mg / L have a pH value of 1-3 and belong to acidic solutions or relatively strong acidic solutions, and helps to enable the chlorine dioxide solution to be neutral, and thus the chlorine dioxide solution possesses relatively wide application value.

Description

technical field [0001] Chlorine dioxide (disinfectant, fungicide). [0002] Molecular formula: ClO 2 . [0003] Relative molecular mass: 67.45. [0004] Chlorine dioxide has been recognized both at home and abroad as a high-efficiency, widespread, fast, and non-toxic bactericidal disinfectant. Because it is completely non-carcinogenic, toxic, and teratogenic, it is listed as an AI-grade safe disinfectant by the World Health Organization (WHO). It can quickly kill various bacterial propagules, Candida albicans, Escherichia coli and Bacillus subtilis spores, and can inactivate hepatitis virus and kill algae spores. It has good killing and therapeutic effects on human skin bacteria and viruses. At present, chlorine dioxide can be used in the production and sales of disinfectants, fresh-keeping agents, algicides, water treatment agents and other products, and can also be used in the development, production and sales of pesticide fungicides and pharmaceutical (external use) d...

Problems solved by technology

[0008] Chinese Patent Application Publication No. CN 101946798A discloses a kind of binary neutral chlorine dioxide disinfectant and its preparation method, but in the claims, instructions and examples However, there is no description or a test report to prove its pH value, and it cannot be determined whether it is acidic or neutral

[0010] Defects in prior art: acidic chlorine dioxide solution has certain defects

Therefore, acidic chlorine dioxide should not be used in the above two fields
