Unitary solid chlorine dioxide effervescent tablet and preparation method thereof

Abstract

The invention discloses a one-variable solid effervescent tablet and a preparation method for the tablet. The material system of the effervescent tablet comprises chlorite, solid acid source, free halogen source, activated Promoter, desiccant, bond, release agent, effervescent and surfactant. The preparation technique includes: after the coating processing with chlorite grains, drying and mixing well with other raw materials according to a specific proportion and technique requirements to prepare compound raw materials, and then pressing into tablets with different specification and shaping on the tablet machine to fit for application in various occasions. The effervescent tablet can quickly release chlorine dioxide and acquire pellucid water solution of chlorine dioxide while dissolving in the water, which is high in stability, rapid in dissolving rapid and strong in bactericidal ability.

Description

technical field [0001] The invention belongs to the field of chemical industry and pharmacy, and relates to an effervescent tablet capable of rapidly producing chlorine dioxide after being dissolved in water, in particular to a monobasic solid chlorine dioxide effervescent tablet and a preparation method thereof. Background technique [0002] Chlorine dioxide is an internationally recognized fourth-generation disinfectant. Its disinfection effect and environmental protection performance are superior to those commonly used disinfectants such as hypochlorite, chlorine gas, ethylene oxide, and glutaraldehyde. Compared with chlorine, it does not produce carcinogens such as halogenated alkanes when it is used for drinking water disinfection. Yet chlorine dioxide is gas at normal temperature, and very unstable, meets reducing substance and just reacts, and decomposes after encountering light, so chlorine dioxide must be produced on the spot, uses up as soon as possible, and this b...

Problems solved by technology

Yet chlorine dioxide is gas at normal temperature, and very unstable, meets reducing substance and just reacts, and decomposes after encountering light, so chlorine dioxide must be produced on the spot, uses up as soon as possible, and this brings a negative impact on the popularization and use of chlorine dioxide Inconvenience

[0003] Chlorine dioxide generators are expensive, not suitable for small occasions such as civil use, and require professionals for operation and maintenance, so they can only be promoted in industrial occasions; for this reason, someone invented stable chlorine dioxide, and the two solutions were installed in two Chlorine dioxide can be produced by mixing the two solutions when in use

Chlorine dioxide powder has disadvantages during use: when dissolving, if a small amount of powder is placed in a relatively large amount of water, the amount of chlorine dioxide produced will be very low, the main reason being that the powder particles spread rapidly in the water , can not fully contact the reaction, in order to obtain a higher conversion rate, the powder must be dissolved in water less than 100 times its weight for activation. Due to the high reaction concentration, a large amount of chlorine dioxide gas escapes, resulting in the loss of active ingredients and the use inconvenient

However, this patent does not discuss the preparation process of the block composition and the treatment of raw materials, nor does it involve the storage stability of the block composition
