Wallpaper-Wallpaper is a raw material and a single product. The wallpaper is paved with varnish and wallpaper glue first, and then the wallpaper is paved. At this time, the shape of wallpaper has changed a lot. After the wallpaper is pasted, the wallpaper glue is covered inside, and formaldehyde is difficult to volatilize, so the release cycle of formaldehyde is much longer than that of wall paint.
Wall paint-Wall paint also contains formaldehyde, but the construction procedure is less than wallpaper. Comparatively speaking, after normal latex paint is painted, it almost evaporates in three days, and it has no taste in 15 days. But there is another pollution in wall paint, that is, mercury and lead. After painting the wall, children can easily touch it with their hands, and some children will habitually suck their fingers, so that mercury and lead in the paint will have an impact on their bodies. Developed countries such as Europe and America also used paint as the first choice for interior decoration as early as the forties and fifties, but it is basically not used now.
As can be seen from the above comparison, both wallpaper and wall paint have their own environmental protection problems. Therefore, on the one hand, it is not recommended that you spread wallpaper; On the other hand, we also have a good reason to choose wallpaper. After all, the effect created by wallpaper can't be achieved by wall paint.
