News: At present, most of the wallpaper on the market without exception to advertise their own products are environmental protection wallpaper, environmental protection as a gimmick seems to become a necessary means of publicity. It is difficult for the average consumer to find a positive answer from the product description, so how to test the green wallpaper? Perhaps three important references can demystify consumers.
some time ago, the "plasticizer" storm pushed the wallpaper industry to the forefront, but also let many consumers understand that PVC wallpaper is the most likely to bring harmful substances wallpaper products. In daily life, it is also easy for consumers to understand that PVC wallpaper is the most common type of wallpaper that emits odors. Whether or not the odor is commonly used by consumers to determine whether it contains toxic substances, and PVC wallpaper odor, on the one hand, because pvc itself contains plasticizers, polyethylene, PVC and other elements, so it emits an inherent odor. On the other hand is caused by the choice of inks and solutes, in a short period of time, these organic solvents will be basically volatile, wallpaper will gradually reduce the taste, so, after the completion of construction, after 1-2 weeks of window ventilation, the smell will gradually disappear.
But not all pvc wallpaper has a taste, which also depends on the wallpaper production process, most wallpaper in the production process, will experience coating, printing and flowering section three times greater than 90 degrees C process high temperature environment, the residual PVC is basically volatile, there will be no taste, and no volatility, can only rely on the construction after the natural evaporation.
did you get that "toxic" wallpaper? Why do some wallpapers contain toxic substances? With the following three references, consumers can see why some wallpapers are eco-friendly wallpapers, while others are respectable.
At present, most of the formal manufacturers used in the original paper is strictly in accordance with environmental standards, provided by European and American manufacturers, and many engineering wallpaper and small manufacturers of raw paper will use lower prices of domestic paper. So some miscellaneous and irregular brands are more likely to contain formaldehyde.
the first assessment project of international wallpaper environmental certification is heavy metal in pigments, the main process gap between domestic wallpaper and imported wallpaper is in the quality, color and stability of wallpaper pigments. This is the main reason for the high price of imported wallpaper.
in normal environmental conditions, PVC does not pose any harm to the human body, only at high temperatures, or fire will break down chlorine gas. And high-quality wallpaper after a rigorous process and technical production, vinyl chloride rarely remains in the product, fully in line with international testing standards.
