Chlorine dioxide gel product capable of decomposing formaldehyde for long time

Abstract

The invention discloses a chlorine dioxide gel product capable of decomposing formaldehyde for a long time. The chlorine dioxide gel product comprises an outer shell, an air pump, a uniform fan, a chlorine dioxide gel strip, a gel strip carrying plate, a gas one-way valve, an electrostatic dust removal net, a formaldehyde sensor, a processor and a storage battery, wherein the chlorine dioxide gel strip comprises a chlorine dioxide precursor, tannic acid, aniline, nano titanium dioxide, a porous carrier, an activating agent, a stabilizing agent, a gelling agent, a cross-linking agent and an aromatic agent. The method comprises the following steps: mixing an activating agent and a chlorine dioxide precursor to obtain an activated chlorine dioxide parent; and mixing the chlorine dioxide parent with tannic acid, aniline, nano titanium dioxide, a stabilizing agent, a gelling agent, a cross-linking agent and an aromatic agent to obtain a chlorine dioxide gel system, and immobilizing the chlorine dioxide gel system into the pore channels of a porous carrier. According to the invention, the chlorine dioxide gel strip has the advantages of being good in stability and stable in release speed, disinfection gas decomposed by the chlorine dioxide gel strip can be stably and continuously released into air for purification, and long-acting and efficient effects are achieved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a chlorine dioxide gel product capable of decomposing formaldehyde for a long period of time. Background technique [0002] Chlorine dioxide has strong oxidizing properties and is widely used in the field of environmental protection technology. At present, volatile organic compounds such as formaldehyde and toluene released by decoration materials have become the main pollutants in the indoor environment. People who stay in the environment where these pollutants exceed the standard for a long time will seriously endanger their health. Organic substances such as formaldehyde and toluene are oxidized into non-toxic and harmless carbon dioxide and water, thereby removing these pollutants. [0003] The strong oxidizing property of chlorine dioxide is also often used as a bactericidal disinfectant. Low concentration of chlorine dioxide can kill bacteria, keep vegetables and ...
