Embodiment 1

[0033] Such as figure 1 As shown, the partition wall system capable of purifying air in this embodiment includes an inner gypsum board 1 , a keel 2 , an insulating layer 3 , a cavity 4 , an ultraviolet lamp 5 , a one-way breathing membrane 6 and an outer gypsum board 7 .

[0034] 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 .

[0035] The surface near the keel of the inner layer gypsum board 1 is sprayed with an effective content of 2g / m 2 Formaldehyde-degradable TiO under UV light 2 .

[0036] 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 core of the outer layer gypsum...

Embodiment 2

[0041] 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.

[0042] The formaldehyde purification effect of the partition wall system of Example 1-2 is shown in the table below:

[0043] serial number 24h formaldehyde purification rate Example 1 90.3％ Example 2 77.0％

Abstract

The invention discloses a partition wall system capable of purifying air. The partition wall system comprises an inner-layer gypsum board, a keel, a heat-insulating layer, a one-way breathing membrane, a cavity, an ultraviolet lamp and an outer-layer gypsum board, wherein the one-way breathing membrane is arranged between the heat-insulating layer and the outer-layer gypsum board; the cavity is formed between the heat-insulating layer and the one-way breathing membrane; the cavity is communicated with an exhaust outlet of a house through fluid; the ultraviolet lamp is arranged at the top of the cavity; the surfaces of the inner-layer gypsum board and the outer-layer gypsum board are spray-coated with ultraviolet formaldehyde degradable materials, namely TiO2 photocatalytic materials; the outer-layer gypsum board further comprises a formaldehyde adsorbing material. The partition wall system provided by the invention has the functions of degrading the formaldehyde and purifying the air.

Description

technical field [0001] The present application relates to but is not limited to a partition wall system capable 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 present application provides a partition wall system capable of purifying air. [0005] Specifically, the appli...
