Compared with traditional wallpaper, its products have the advantages of good gloss, not easy to crack, waterproof and wear-resistant, and simple construction.
In particular, "liquid wallpaper" does not need to use 107 glue, polyvinyl alcohol, etc. In the process of construction, it does not contain heavy metals such as lead and mercury and aldehydes, and different styles of patterns are made on the wall through special molds.
To be sure, the qualified "liquid wallpaper" is indeed a non-toxic and harmless environmental protection building material.
However, in order to seek profits, some unscrupulous merchants use inferior glue paint to blend counterfeit "liquid wallpaper", which makes the current liquid wallpaper market chaotic.
Fake liquid wallpaper will lead to indoor volatile organic compounds (VOC) exceeding the standard. If people stay in such an environment for a long time, it will affect the central nervous system and immune function, causing headache, fatigue and inattention.
In addition, due to the complex sources of indoor VOC, paint is only one of many sources of indoor VOC.
Moreover, VOC in the study refers to volatile organic compounds with boiling point between 50℃ and 260℃ and saturated vapor pressure exceeding 133.2Pa at room temperature, so it is not divided and selected from the perspective of health.
Therefore, even if the VOC concentration in product identification is very low, even "zero VOC", it may cause harm to human health.
