Embodiment 2

[0037] Embodiment 2: Performance experiment of the chlorine dioxide slow-release sterilization card according to the present invention.

[0038] Put a group of samples 1, 2 and children's and adult products of the same Japanese sterilization card Air Doctor in the same indoor environment, and measure the ClO released by samples 1, 2 and Japanese products when blowing air 2 gas concentration. Thereafter, CO was continuously introduced 2 , measure ClO every 30 minutes 2 gas concentration. In addition, another group of samples 1 and 2 prepared under the same conditions and Japanese products were sealed for 12 hours to measure ClO 2 gas concentration.

Embodiment 3

[0039] Embodiment 3: The effective action time experiment of the chlorine dioxide slow-release sterilization card of the present invention.

[0040] Put samples 1, 2 and the similar Japanese product Air Doctor in the same indoor environment, and record the ClO released at 0d, 1d, 2d, 7d, and 10d 2 concentration.

[0041] From the test results, it can be seen that the initial release of ClO by the chlorine dioxide sterilizing card loaded on natural zeolite 2 The concentration is similar to the Japanese Air Doctor children's model, about 5ppm; the chlorine dioxide sterilization card loaded with artificial zeolite initially releases ClO 2 The concentration is similar to the Japanese Air Doctor adult model, about 10ppm.

Abstract

The invention discloses a slow-release chlorine dioxide disinfection card taking zeolite as a carrier, and mainly relates to the field of chlorine dioxide disinfection. The invention relates to a chlorine dioxide sustained-release agent and a preparation method thereof, and aims to overcome the defects of unstable chlorine dioxide gas, short product preservation time and the like in the prior art. According to the invention, a natural zeolite material is used as a carrier and is compounded with sodium chlorite and a combined catalyst, and moisture and carbon dioxide in air are used for participating in a reaction to generate slow-release chlorine dioxide, so that the release rate of chlorine dioxide gas is artificially controllable, and bacteria and viruses are killed. The disinfection card has an ultra-long slow-release capability of more than 30 days, and plays an effective role in the aspects of protecting susceptible people from virus invasion, purifying harmful components in air and the like.

Description

technical field [0001] The invention relates to the field of chlorine dioxide disinfection, in particular to a slow-release chlorine dioxide disinfection card with zeolite as a carrier and a preparation method thereof. Background technique [0002] How to effectively disinfect the air and reduce the mutual infection caused by air transmission has always attracted the attention of all walks of life. Air disinfection is one of the methods to cut off the spread of respiratory infectious diseases. The currently recognized methods for air purification include ultraviolet light disinfection, air purification equipment disinfection and chemical disinfection. The chemical air disinfection method usually uses 3% hydrogen peroxide, 0.5% ~ 1% (5g / L ~ 10g / L) peracetic acid aqueous solution or chlorine dioxide solution (0.01mg / L ~ 0.02mg / L) for disinfection by heating and evaporation , this method has safety risks and limits its application in conventional households; and sodium hypochl...
