Wallpaper quality identification method
Generally, the wallpaper should be identified from the following aspects:
1. Paper base thickness. It is guaranteed to use natural wood pulp paper of greater than or equal to 100 g/m 2 as the substrate. When purchasing, please ask the merchant to issue the manufacturer's documents.
2, product strength. The surface coating thickness is guaranteed to be greater than 150 g/m2. The wet tensile load is greater than 7 liters per 15 MM vertical/horizontal. These two features will ensure that the construction is easy to level, not curled, bottomless, and the surface can be peeled off.
3. Resistance to friction. When you purchase, you can use the nail to scratch the surface of each wallpaper to see if there are scratches or discoloration and peeling to identify the surface toughness.
4. Green is harmless. When purchasing, it is possible to get close to the product and smell any odor. The odorous product may contain excessive aromatic hydrocarbons (toluene, ethylbenzene), which may have carcinogenic effects.
5, the color is long. The wallpaper surface coating materials and printing pigments need to be optimized and strictly controlled to ensure that the wallpaper does not yellow after long-term illumination (especially light color, white wallpaper).
6. See if the pattern style is unique and the production process is excellent.
