Problems solved by technology

[0003] At present, the process of producing solid chlorine dioxide release agent is mostly acidified sodium chlorite method. In view of the fact that sodium chlorite is very easy to react with solid acidifying agent and release chlorine dioxide immediately, the currently used chlorine dioxide disinfectant Most of them pack sodium chlorite and solid acidifier separately, and this kind of binary packaging is cumbersome to operate in use
[0004] Chinese patent CN1104610A discloses a production method of stable chlorine dioxide, melts white wax or stearic acid or beeswax as a coating agent, adds sodium chlorite to make microcapsule particles, and then mixes them with dry tartaric acid or oxalic acid particles Mixed bagging, the disadvantage of this production method is that the coating agent has poor water solubi...

Abstract

A stable solid ClO2 disinfectant is prepared from sodium chlorite, solid acid, composite coating agent and composite trigger through compounding and passivating. Its advantages are high stability and safety, and long storage period.

Description

technical field [0001] The invention belongs to the technical field of antibacterial disinfectants and relates to an improved production method of chlorine dioxide disinfectants. Background technique [0002] Chlorine dioxide is an excellent high-efficiency, broad-spectrum, non-toxic, and non-residual disinfectant. Because it does not produce carcinogenic, suffocating, and mutagenic effects, it has been widely studied and used worldwide in recent years. [0003] At present, the process of producing solid chlorine dioxide release agent is mostly acidified sodium chlorite method. In view of the fact that sodium chlorite is very easy to react with solid acidifying agent and release chlorine dioxide immediately, the currently used chlorine dioxide disinfectant Most of the sodium chlorite and the solid acidifier are packaged separately, and this binary package is cumbersome to operate in use. [0004] Chinese patent CN1104610A discloses a production method of stable chlorine dio...
