Embodiment 1

[0030] The method for purifying air in this embodiment includes installing a partition wall system with air purifying function in the house.

[0031] Such as figure 1 As shown, the partition wall system with air purification function in this embodiment includes inner gypsum board 1 , keel 2 , insulation layer 3 , cavity 4 , ultraviolet lamp 5 , one-way breathing membrane 6 and outer gypsum board 7 .

[0032] The cavity 4 is arranged between the insulation layer 3 and the one-way breathing membrane 6, and is in fluid communication with the air outlet of the fresh air system of the house; the ultraviolet lamp 5 is arranged on the top of the cavity 4 ; The one-way breathing membrane 6 is set between the heat insulation layer 3 and the outer gypsum board 7 .

[0033] The outer surface of the outer layer gypsum board 7 is sprayed with an effective content of 2g / m 2 Formaldehyde-degradable TiO under UV light 2 , the board core of the outer layer gypsum board 7 contains 10% diatom...

Embodiment 2

[0038] The only difference between this embodiment and Embodiment 1 is that the partition wall system does not include a cavity, an ultraviolet lamp and a one-way breathing membrane.

[0039] Please see the following table for the formaldehyde purification effect of the method for purifying air of embodiment 1-2:

Abstract

The application of the invention discloses an air purifying method, the method comprises a partition wall system having an air purifying function, the partition wall system comprises an inner layer gypsum board, a keel, a thermal insulation layer and an outer layer gypsum board, a visible light formaldehyde degradable material, namely a modified TiO2 photocatalytic material, is sprayed on the surface of the outer layer gypsum board, and the outer layer gypsum board further internally comprises a formaldehyde adsorption material. The air purifying method provided by the application of the invention has the functions of effectively removing harmful gases indoors like formaldehyde and purifying the indoor air.

Description

technical field [0001] The present application relates to but is not limited to a method of purifying air. Background technique [0002] Indoor formaldehyde pollution mainly comes from furniture, wood-based panels, various adhesive coatings and synthetic textiles, etc. Indoor formaldehyde pollution affects people's health and has aroused great concern. The hazards of indoor formaldehyde to human health mainly include stimulating effect, toxic effect and carcinogenic effect. If effective measures are not taken, the volatilization of formaldehyde lasts for as long as 3-15 years, seriously affecting the quality of indoor environment where people live. Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summary is not intended to limit the scope of the claims. [0004] The application provides a method for purifying air. [0005] The method for purifying air provided by the present application includes ad...
