Problems solved by technology

However, when sulfate cement is used to adsorb chlorine dioxide solution, its water absorption rate and volatile concentration per unit volume are low, and the volume of the obtained product is correspondingly large and heavy, and cannot be recycled repeatedly.
If the chlorine dioxide solution is placed in a container for direct natural volatilization, it can be sterilized for a short time, but the volatilization speed of the solution is fast, the disinfection time is short, and the concentration value of chlorine dioxide gas in the unit space fluctuates greatly. When the concentration is high, it will have adverse effects on human health, and when the concentration is low, it will not have the effect of sterilization and disinfection, and it is difficult to meet the requirements of continuous, stable and long-term disinfection and sterilization
And it is not convenient to place and keep the chlorine dioxide aqueous solution, nor is it safe.

Embodiment 1

[0027] Get 15 grams of chlorine dioxide solution with a stability of 2%, 15 grams of silica gel, and 0.3 gram of citric acid. After mixing the three, make a spherical shape with a mold to obtain a spherical colloid compound. Place the spherical colloid compound in a cylindrical upper opening container with the same diameter, place it in a room with an area of ​​33 square meters, close the doors and windows, and detect that the number of bacteria falling on it reaches more than 90% at normal temperature (20-25°C). The number of days is 70 days, that is, the sustained release period of the compound is 70 days.

Embodiment 2

[0029] Get 25 grams of chlorine dioxide solution with a stability of 2%, 25 grams of silica gel, and 0.5 gram of citric acid. After mixing the three, make a spherical shape with a mold to obtain a spherical colloid compound. The detection method is the same as in Example 1, and the sustained release period of the colloid compound is 96 days.

Embodiment 3

[0031] Get 8.5 grams of chlorine dioxide solution with a stability of 2%, 25 grams of silica gel, and 0.15 grams of citric acid. After the three are mixed, they are made into a square shape with a mold to obtain a cube colloid compound. The detection method is the same as in Example 1, and the slow-release period of the colloid compound is 55 days.

Abstract

The present invention is slow released ClO2 air disinfectant, and belongs to the field of hygienic disease controlling and sterilizing technology. The slow released ClO2 air disinfectant consists of ClO2 solution in 1-3 weight portions, silicon gel as the carrier of ClO2 solution in 3 and activator in 0.005-0.1 weight portions. The slow released ClO2 air disinfectant has homogeneous and lasting release to maintain proper ClO2 concentration in the air and reach excellent air disinfecting effect. The used silicon gel may be recovered and reused after treatment.

Description

Technical field [0001] The invention relates to an air disinfectant, in particular to a slow-release chlorine dioxide air disinfectant. technical background [0002] People often live in an environment where various infectious pathogenic microorganisms and germs are easy to infect and infect. Therefore, epidemic prevention and disinfection in the environment is an important measure to kill various infectious pathogenic microorganisms and bacteria, prevent and control epidemics, and protect health. Spraying Disinfectants such as: (peracetic acid disinfectant, chlorine dioxide solution, sodium hypochlorite solution) are all liquid, the disinfection time is too short, and the disinfection quality is not high (taken away with the air flow). Smoked vinegar, ultraviolet lamp sterilizer, and ozone sterilizer are common ways to sterilize the environment at present. But they are inconvenient to use, and the disinfection time is too short, and the disinfection quality of the liquid s...
