Abstract

The invention discloses a binary-packaged reactive chlorine dioxide tablet which comprises an independently-packaged tablet A and an independently-packaged tablet B, wherein the tablet A is prepared into tablets from the following raw materials through mixing and pressing: 55-65wt% of native agent, 8-12wt% of dissolution agent, 8-11wt% of foaming agent, 8-11wt% of adhesion agent, 8-11wt% of forming agent, and 0.01-0.5wt% of mould release agent; and the tablet B is prepared into tablets from the following raw materials through mixing and pressing: 35-50wt% of acidating agent, 20-30wt% of catalyst, 3-8wt% of foaming agent, 10-15wt% of adhesion agent, 10-15wt% of forming agent, and 0.05-0.2wt% of mould release agent; then, the tablet A and the tablet B are respectively coated by a coating agent so as to obtain the binary-packaged reactive chlorine dioxide tablet. When the binary-packaged reactive chlorine dioxide tablet is used, chlorine dioxide gas can be generated just by adding the tablet A and the tablet B into water in certain proportion to dissolve, thereby achieving the effects of sterilization and disinfection. The binary-packaged reactive chlorine dioxide tablet disclosed bythe invention is high in conversion rate, easy to store and high in product stability.

Description

technical field

[0001] The invention belongs to the technical field of chlorine dioxide disinfection, and in particular relates to a binary reaction 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, b...
