All three are three-dimensional wallpapers, and the differences are as follows:

1. Visually, the three-dimensional effect of high D wallpaper is more prominent than that of low D wallpaper, which is more stereoscopic and realistic;

2. Tactile (technically), compared with low D number, high D number not only enhances the stereoscopic effect of texture style visually, but also enhances the depth of surface concave-convex texture in tactile sense, making the texture more stereoscopic. To the touch, they all look three-dimensional;

3. In use, whether it is high D or low D, it can achieve a good decorative effect. The low D is completely flat. Although it is not as strong as the high D, it is more convenient to take care of and is not easy to accumulate dust. The high D stereoscopic effect is concave and convex, with style and more upscale;

4. The process of high D is more complicated, more stereoscopic and more expensive than that of low D..

appropriately purchasing

first, determine the overall cost and overall decoration style of your decoration and the main materials of the decoration.

it's very important to determine the style. in choosing varieties and colors, the first thing to do is to follow the matching style. The second is the place suitable for use. {For example, children's rooms have special editions, public places have engineering wallpaper, and restaurants have wallpaper specially designed for restaurants}. Third, we should conform to our own aesthetic point of view and color matching. It's best for you to make a request and then the decoration designer will choose the appropriate varieties for you, and then you can choose from them. This can avoid unnecessary trouble.

when choosing wallpaper, we should also know the functions of basement membrane (for wall back cover), rubber powder and mucilage, which will directly affect the construction quality and later effect of wallpaper. A complete set of wallpaper construction includes primer glue wallpaper, and any link that is not environmentally friendly will affect the final construction effect. Invisible links-primer and glue are more critical. Many wallpaper construction problems are caused by glue.

colorful wallpaper is beautiful, but don't forget to wipe it with a wet cloth to see if it is discolored, especially some wallpaper with concave-convex texture, which must be cleaned frequently in the future.

the environmental protection level of wallpaper depends on the material, material grade and printing technology, etc., which can be identified by burning samples (the wallpaper with high environmental protection level has no burning odor and smoke, and the ash is gray powder) and smelling (PVC wallpaper has obvious plastic smell, while the wallpaper with low grade has strong printing ink smell). The newly rolled pulp wallpaper without peculiar smell has the highest environmental protection grade.

There are many kinds of wallpaper in the market, but there are also many materials, among which paper-based PVC wallpaper accounts for more than half, and the cost of raw materials is relatively low. Some imported PVC wallpapers have high prices. High-grade wallpaper usually uses pure paper and non-woven fabrics.
