BAIJIAN - Third party testing organization
The methods to identify the quality of wall coverings are as follows: firstly、 to identify the quality of wall coverings、 it is necessary to first check whether there are differences in the color of the wall surface、 whether there are wrinkles and air、 whether the color is uniform、 whether there is color blurring、 etc. If the clarity of the wall coverings pattern is high、 and the clarity of the wall coverings pattern is generally high、 then the quality of the wall coverings is good; You can see the number and level of detail of the wallpaper、 and you must see both sides. Generally、 the higher the density of the surface fabric、 the better the quality of the wallpaper. When purchasing、 touch the wallpaper with your hand and feel if its texture is good. Some people believe that thicker wall coverings are better、 but industry insiders call this a misconception. The quality of wallpaper is mainly related to its craftsmanship and toughness、 but not directly related to its thickness. If you use manual identification of wallpaper、 you need to carefully feel the feel and toughness of the wallpaper、 especially for flocked walls、 which are easy to distinguish the quality of the wallpaper by hand. Usually、 the softer and more comfortable the feel、 the better the quality of the wallpaper、 and the stronger its flexibility. However、 if wall coverings of the same material are compared with imported wall coverings、 the imported wall coverings are relatively thicker and have a slightly higher density than domestic products. San Wen is a very important way to distinguish between good and bad when purchasing wallpaper. According to the environmental characteristics of the wallpaper、 if it is made of inferior materials、 it will have a pungent odor. When you carefully smell it、 you can smell its taste. If there is odor、 formaldehyde、 vinyl chloride、 etc. on the wallpaper、 the volatility may be high. Good wall coverings with four measurements have waterproof and mold resistant properties、 so when purchasing wall coverings、 you can pour a little water on the wall and observe for 2-3 seconds. If the water does not penetrate the wall、 it indicates that the waterproof performance of the wall is very high、 and on the contrary、 the waterproof performance of the wall is insufficient. And when purchasing、 you can cut the sample and wipe the surface with a damp cloth to see if there is any discoloration
