Extended data:
Whether wallpaper is toxic or not depends on the following three points:
1, mass
As for wallpaper, you need to look at the quality, not the material. Some families will know that putting wallpaper on the internet is toxic before decoration, but most of them focus on the material of wallpaper.
In many people's impression, paper and metal wallpaper are non-toxic, while PVC wallpaper is toxic. This view is wrong. Whether it is PVC, metal or non-woven fabrics, as long as they meet the national quality inspection standards, they are all non-toxic products and will not affect human health. It depends on the quality, not the material.
Step 2 glue
Want to paste wallpaper is not only to buy wallpaper, but also to buy glue to paste. So not only the quality of wallpaper, but also the quality of glue. If the glue is unqualified, the product may still release toxic and harmful gases such as formaldehyde, thus affecting human health. Therefore, pasting wallpaper in this way is definitely toxic and will seriously affect human health.
3. Certificate
In order to further clarify the quality of wallpaper products, consumers can directly check the relevant certificates of the products to judge. For example, the problem of toxic wallpaper needs attention, including the quality inspection certificate and safety certificate of wallpaper, glue and other products.
In fact, for newly renovated houses, no matter how high-grade wallpaper and high-quality glue are, there will be some peculiar smell more or less. Therefore, if the wall is a safer and healthier lifestyle, then its new wallpaper must have certain toxicity.
Only a few have little impact on human health. In order to eliminate this influence, it is best to put the newly-installed houses on hold for a period of time to allow all harmful gases to evaporate.
