Second, formaldehyde molecules are captured and activated by activated alumina, which makes them easily oxidized and decomposed by oxygen in the air, thus being completely removed. This catalytic decomposition does not depend on light, thus making up for the shortage of photocatalyst. It can be used in in addition to formaldehyde at night, closets, drawers and other places where other in addition to formaldehyde products can't play a role, but it is precisely the place where it needs to play a role most.
Third, the magic bean formaldehyde network judges whether there is formaldehyde exceeding the standard in its own environment through the discoloration of magic beans.
1. Magic beans have two reaction mechanisms. One is its matrix, pure aldehyde stone, which can effectively purify formaldehyde in catalytic air and decompose it at the moment of adsorption.
2. The other is the exclusive patent of molecular probe, which can change color synchronously in the process of removing formaldehyde, so that consumers can know the removal of formaldehyde in the air in real time, and consumers can take corresponding measures according to the discoloration of magic beans, such as opening windows for ventilation, or staying away from the scene, or taking other measures.

Formaldehyde treatment method
1. ventilation method: a simple, practical, economical and effective method. Let nature purify indoor air more effectively than any product. Believe that the power of nature is infinite. Even if air purification products are used, it is necessary to keep indoor ventilation, which is not only helpful for natural purification, but also helpful for air purification products to play their own adsorption role.
2. Plant method: Putting some green plants at home can not only remove formaldehyde, but also beautify the living environment. This is a way to kill two birds with one stone. Although plants can adsorb formaldehyde, their adsorption capacity is limited, so it is not realistic to rely solely on plant in addition to formaldehyde. It can only play an auxiliary role.
3. Activated carbon method: It mainly uses activated carbon and other materials to adsorb polluted gases, which is not only physical adsorption, but also the best physical removal method at present. Its principle is that the porous structure of activated carbon provides a large amount of surface area, which is very easy to achieve the purpose of adsorbing and collecting impurities. All molecules attract each other like a magnetic force.
4. Photocatalyst method: under the irradiation of light, photocatalyst will produce a photocatalytic reaction similar to photosynthesis, producing free hydroxyl and active oxygen with strong oxidation ability, which has a strong photo-redox effect.
5. It can oxidize and decompose various organic compounds and some inorganic substances, destroy the cell membrane of bacteria and solidify the protein of virus, kill bacteria and decompose organic pollutants, and decompose organic pollutants into pollution-free water (H? O) and carbon dioxide (CO? ), so it has strong functions of sterilization, deodorization, mildew prevention, antifouling, self-cleaning and air purification.
6. Catalytic oxidation of active manganese: The oxidant based on manganese oxide (active manganese) has strong performance of degrading formaldehyde, which can directly decompose formaldehyde into carbon dioxide and water without secondary pollution. At present, active manganese formaldehyde decomposition tablets have been made, which is a cheaper, environmentally friendly and efficient in addition to formaldehyde method.
