Problems solved by technology

[0005] However, this type of slow-release method generally relies on solutions and hydrogels for activation. Chlorine dioxide is prone to self-oxidation-reduction disproportionation reactions in aqueous solutions and decomposes into substances that cannot regenerate chlorine dioxide. It tends to happen when the pH value is maintained at weakly acidic to weakly alkaline, and the temperature rises, the reaction speed is easily accelerated, which will cause a large amount of reactant loss or slow release out of control, and a large amount of chlorine dioxide will be released in a short time
Chlorine dioxide and its pre-reactants are easily affected by light. Under the catalysis of strong light, chlorine dioxide will quickly decompose and generate toxic chlorine gas, which loses the effect of using chlorine dioxide for safe air disinfection

Embodiment 1

[0041] According to 37 parts of kaolin, 23 parts of diatomite, 10 parts of ferrite tourmaline, 8 parts of sodium fatty acid, 7 parts of potassium carbonate, 10 parts of crystal redite titanium dioxide, and 5 parts of nano-carbon black, ball milling for 30-60 minutes, the obtained particle size Divide the obtained ceramic powder into two parts, and one part is sprayed to make a hemisphere with a diameter of 8mm and a thickness of 1.5mm. First, it is fired at a temperature of 650°C ± 10°C for 30 minutes. During the firing process, the furnace is continuously fed with atmospheric nitrogen for protection.

[0042] The other part is glazed by spraying, so that a 0.1-0.2mm glaze is formed on the surface of the ceramic ball. Air is introduced to normal pressure, and the glaze is fired for 30 minutes at a temperature of 1130°C±10°C. At this time, the nano-carbon powder reacts, leaving micropores. The enamel surface wants to be ablated through micropores to form micropores of 200-300...

Description

technical field [0001] The invention belongs to the field of daily air fresheners, in particular to a chlorine dioxide slow-release air freshener. Background technique [0002] Due to its strong oxidation and bleaching properties, chlorine dioxide can decompose ammonia, sulfur compounds, unsaturated hydrocarbons, and some VOCs in the air, and can effectively remove trace odors in the air. At the same time, it also has a strong destructive effect on the proteins of bacteria, fungi, and algae, and can quickly kill microorganisms in the air and attached to the surface of ordinary objects, thereby further eliminating musty, rotten, and other odors that are difficult to eradicate in the air. Substances suitable for carrying out air fresheners. [0003] Chlorine dioxide has an obvious pungent odor when the concentration is high, and it will cause discomfort to people. Studies have shown that chlorine dioxide does not need a high concentration that makes people feel abnormal, 0.01...
