Preparation method of effervescent air purifying agent for removing harmful gas

Abstract

The invention relates to a preparation method of an effervescent air purifying agent for removing harmful gas. According to the preparation method, a convergence adsorbent, organic acid, a foaming agent and a surfactant are uniformly mixed at a certain weight ratio, the mixed material is extruded by an extruding device for forming particles, and the particles are packaged to obtain the effervescent air purifying agent for removing harmful gas. The effervescent air purifying agent can be used under the condition that light is available, and also can be used under the condition that the light source is not available, and thus the use is not limited.

Description

technical field [0001] The invention relates to a preparation method of an effervescent air purifier for removing harmful gases. Background technique [0002] At present, air purifiers are divided into two types, one is a purifier that uses its own fragrance to cover up peculiar smells, and the other is a purifier that uses photocatalysts to degrade harmful gases. The first one is just to cover up the peculiar smell, and it does not clear the harmful gas itself; while the second one is a new type of photocatalyst, under the irradiation of light, the valence band electrons of the nano photocatalyst are excited to the conduction band, forming electrons and holes, and the adsorption Acting on O2 and H2O on its surface, superoxide anion radicals, O2- and hydroxyl radicals -OH are generated. The free radicals have a strong ability to oxidize and decompose, and can destroy C-C bonds, C-H bonds, and C-N bonds in organic matter. , C-O bond, O-H bond, N-H bond, decompose organic m...

The first one is just to cover up the peculiar smell, and it does not clear the harmful gas itself; while the second one is a new type of photocatalyst, under the irradiation of light, the valence band electrons of the nano photocatalyst are excited to the conduction band, forming electrons and holes, and the adsorption Acting on O2 and H2O on its surface, superoxide anion radicals, O2- and hydroxyl radicals -OH are generated. The free radicals have a strong ability to oxidize and decompose, and can destroy C-C bonds, C-H bonds, and C-N bonds in organic matter. , C-O bond, O-H bond, N-H bond, decompose organic matter into carbon dioxide and water; at the same time destroy the cell membrane of bacteria and solidify the protein of virus, change the living environment of bacteria and virus to kill bacteria and viruses, although this method can remove harmful gases , but there must be light when used, and the use is subject to certain restrictions
