2. Use green plants to purify the air: Green plants have a particularly strong adsorption capacity for indoor harmful gases, especially for formaldehyde. Green plants can choose chlorophytum, aloe, cactus and so on. , can play a very good role in purifying the air. When the indoor air quality of aloe is poor, small spots will grow on the surface of its leaves. On the contrary, it shows that the indoor air quality is good.
3. Use peel to remove formaldehyde odor: This is a healthy, environmentally friendly and energy-saving indigenous method, that is, use grapefruit peel and orange peel with strong adsorption ability to remove formaldehyde odor from the house. After the house is wallpaper-pasted, divide the grapefruit skin into small portions and put them in every corner of the room. Put more grapefruit skin in the place where the decoration smell is strong.
4. Activated carbon adsorption method. Activated carbon and bamboo charcoal with adsorption function are also widely used in the process of removing these harmful gases. However, it is determined that the action space of activated carbon is small and the amount of activated carbon is relatively large.
From the environmental performance of wallpaper itself, both paper wallpaper and non-woven wallpaper are environmentally friendly after all. But also does not contain harmful substances such as formaldehyde, and has certain adsorption function. In the production of PVC wallpaper, plasticizers and other additives were added in the production. The added substances themselves contain organic volatile substances, and the smell is volatile, some of which are harmful to human body. But none of the above three types of wallpaper contains formaldehyde.
To bond the environmental performance of wallpaper, the wallpaper to be pasted on the wall needs adhesive, and the adhesive contains formaldehyde. Adhesives are mainly divided into organic solvent type and water-based type. Organic solvent-based adhesives contain not only formaldehyde, but also organic volatiles such as toluene and xylene. Most of the environmentally friendly adhesives on the market are water-based, such as glutinous rice glue. Although these adhesives are more environmentally friendly, some businesses add formaldehyde to them, as if this would cause pollution.
