Decorative wallpaper plays a great role in adjusting the atmosphere in life. Decorative wallpaper is the most widely used wall decoration material at home and abroad. The wallpaper has various patterns, rich colors and flexible production. It can imitate the appearance of many traditional materials, so it is very popular with people. So wallpaper is made of many materials and can be divided into four categories: paper, textiles, natural materials and plastics.
Due to the increasing use of modern wallpapers, some wallpapers are not well made. Wallpaper beautifies the living environment. This will also have a very serious adverse impact on indoor air quality. Therefore, the influence of wallpaper decoration on indoor air mainly comes from two aspects: First, the harmful substances contained in wallpaper. Because the composition of wallpaper is different, its influence is also different. The fabric fragments in natural textile wallpaper, especially pure wool wallpaper, are allergens, which can cause human allergies. Wallpapers are easy to change and rich in patterns, so more and more decorating families like to use wallpapers to match them. When choosing wallpaper, people pay more and more attention to the environmental protection of wallpaper.
There is also a special substance in wallpaper, heavy metal, which also produces formaldehyde. Waterborne or oily like this refers to different solvents used when diluting pigments. For example, water can be used as a diluent for water-based pigments, and it volatilizes in the production process, which has no impact on the factory environment. Moreover, ethyl acetate is used as diluent for oily pigments, and acetic acid and ethyl ester will be volatilized in the production process. If discharged directly, it will pollute the air and environment above the factory, and most factories use recycling devices for treatment.
Because of the raw materials of wallpaper and the way of pigment dilution, there will be the problem of formaldehyde. So be sure to pay attention when choosing wallpaper.
