Abstract
The invention provides a unitary-package-reaction-type chlorine dioxide tablet and a preparation method thereof. The tablet is prepared from the following raw materials: 8-20wt% of raw agent, 25-50wt% of acidulant, 8-20wt% of promoter, 15-25wt% of binder, 0.5-4wt% of lubricant and 10-22wt% of foaming agent. The preparation method comprises the following steps: mixing and pressing the raw materials into white pills; and then coating the white pills by a coating agent to finally obtain the chlorine dioxide tablet. When the chlorine dioxide tablet is in use, chlorine dioxide gas can be generated only by dissolving the tablet in water so as to play roles in sterilization and disinfection. The unitary-package-reaction-type chlorine dioxide tablet obtained by the preparation method has the advantages of high conversion rate, convenience in storage and high product stability.
Description
technical field [0001] The invention belongs to the technical field of chlorine dioxide disinfection, and in particular relates to a reactive chlorine dioxide solid preparation composed of alkali metal or alkaline earth metal chlorite such as sodium chlorite, solid acid and other accelerators. The invention also relates to a preparation method of the solid preparation. Background technique [0002] As a water-soluble strong oxidant, chlorine dioxide has high-efficiency and broad-spectrum bactericidal ability, and can oxidize and decompose bacteria, viruses and other microorganisms, as well as amino acids and other reducing substances in proteins, and can also react with organic matter and various inorganic ions reaction; and, compared with other chlorine-based products, chlorine dioxide will not produce distortion-causing, carcinogenic, mutagenic chloroform and other organic halides during sterilization, and the effect of killing viruses, bacteria, deodorization, bleaching, ...
