What are the classification, advantages and disadvantages of wallpaper?

The wallpaper sold in the market now is mainly divided into: pure paper, PVC material, imitation cloth, natural plant wallpaper, textile wallpaper, metal wallpaper and so on. Pure paper wallpaper Pure paper wallpaper is mainly made of grass, bark and new natural reinforced wood pulp (containing 10% wood fiber yarn). Its outstanding characteristics are good environmental protection, no warping, no foaming, no odor, strong permeability and no mildew. It is the first choice wallpaper for children's rooms in Europe. Moreover, because the patterns of pure paper wallpaper are mostly made by printing technology, the pictures are realistic and the colors are clear. Disadvantages are that the construction technology is difficult, once the operation is improper, it is easy to produce obvious seams, and it is not easy to make patterns with strong layering or three-dimensional sense due to the characteristics of the paper itself (because the paper is flat, it can only be printed, but can't make concave and convex things), and the water resistance and scrub resistance are also poor. However, the new pure paper wallpaper is coated with a thin layer of wax, which is more scrub-resistant, anti-static, dust-free and contains no other organic components. It is a pure natural green wallpaper. Careful observation is needed during the purchase process. Generally speaking, high-quality pure paper wallpaper feels a bit like printing paper, with hard paper and good whiteness (the paper with poor pulp is obviously soft), so that in the production process, the pigment can be evenly colored, the lines are clear, the color is clean, the color retention is good, and it is not easy to fade. If inferior pulp is used, the smoothness of the paper surface is not good, and the pigment tends to face down {MOD}, which is prone to the phenomenon of blurred color, turbid color and weak three-dimensional sense, resulting in the color difference of the wallpaper after it is on the wall, or even fading and turning yellow in a short time. The worst raw material of pure paper wallpaper is recycled paper, which is made of recycled waste paper through a series of processes such as pulping and bleaching, and then printed on it. This kind of wallpaper is prone to the above problems in addition to rough paper. Due to the addition of more chemical raw materials in the production process, its environmental protection is not optimistic, and some even have a great odor, so this wallpaper is generally not used for home decoration. Now, some things are getting better and better. Without professional knowledge, it is difficult to tell. Relatively speaking, a better reference method is to look at the price. Generally speaking, except for the special price, the average price of high-quality pure paper wallpaper will not be lower than 200 yuan/roll (5.3 square meters). Of course, I said the best paper type. If you add special design fees (buy design drawings from abroad) or import pigments, paper-based adhesive wallpaper
