Embodiment 1

[0030] 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 .

[0031] 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 .

[0032] 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% diatomaceous earth (based on the weight of the plaster of paris for preparing the outer layer gypsum board).

[0033] The surface near the cavity of ...

Embodiment 2

[0037] 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.

[0038] The formaldehyde purification effect of the partition wall system of Example 1-2 is shown in the table below:

[0039] serial number 24h formaldehyde purification rate Example 1 90.3％ Example 2 77.0％

Abstract

The application of the invention discloses a partition wall system having an air purifying function, the partition wall system comprises an inner layer gypsum board, a keel, a thermal insulation layerand 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 partition wall system provided by the application of the invention has the functions of degrading formaldehyde and purifying air.

Description

technical field [0001] This application relates to but is not limited to a partition wall system with air purification function. 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 present application provides a partition wall system capable of reducing indoor formaldehyde. [0005] Specifica...
