Sources of wallpaper pollution:
Most wallpapers are relatively environmentally friendly because they are natural materials, but people should pay special attention to wallpaper accessories. The use area of wallpaper accessories is not less than that of wallpaper, and its quality has a long-term impact on the indoor environment.
Wallpaper accessories refer to wall treatment materials and wallpaper adhesives. The adhesive is urea-formaldehyde resin with formaldehyde as the main component. All the boards that need glue have formaldehyde. Because all artificial boards contain formaldehyde, the use of artificial home products can't escape the "claws" of formaldehyde. In addition, many furniture will contain formaldehyde if they are glued together.
shopping tips
There are two kinds of home wallpaper: fiberglass wallpaper and polyethylene plastic wallpaper. The former has a good texture, similar to cotton, but the fiber gap is easy to accumulate dust, not easy to clean, and it is easy to leave "sweat marks" after wetting. The latter is waterproof, non-shedding, sound-absorbing, flame-retardant, easy to clean, durable and other advantages, and the color variety is also very rich, including multi-color printing, foaming, embossing and so on. Printed plastic wallpaper is rich in color and strong in decoration, foamed plastic wallpaper has strong texture and unique three-dimensional relief effect, and embossed wallpaper has a crown satin flash and charm.
When buying wallpaper for wall decoration, you should choose one with uniform color and full pattern to avoid paper folding, color difference between left and right, pollution, paper film separation and other defects. Two or more volumes of the same wallpaper: buy the same batch of products to prevent color difference. In addition, we should also pay attention to the harmonious relationship between wallpaper and indoor furniture display, color tone and style.
The demand for wallpaper is about 2.5-3 times of the square meter of each room in ordinary residential buildings. For example, the room area is about12m2; It is enough to buy 30-36m2 wallpaper.
Look: See if there are color differences, wrinkles and bubbles on the surface of the wallpaper, whether the pattern of the wallpaper is clear and whether the color is uniform.
Feel: After reading it, you can touch the wallpaper with your hand to feel its texture and whether the thickness of the paper is consistent.
Wen: This is very important. If the wallpaper has an odor, it is likely that the content of volatile substances such as formaldehyde and vinyl chloride is high.
Wipe: You can cut a wallpaper sample and wipe the paper with a wet cloth to see if it changes color.
When purchasing wallpaper, we should also pay attention to the different materials and prices of wallpaper. At the same time, the price of wallpaper with the same material will vary widely because of some differences in thickness, environmental protection and dirt resistance. In order to choose wallpaper that is more symmetrical with the value, we still have to look at the brand without knowing how to look at the quality. A good brand has a higher price, but its quality is more assured. At the same time, the price of new wallpaper is relatively higher than that of old wallpaper, and the after-sales service of wallpaper with higher price will be more comprehensive.
The environmental protection degree of wallpaper depends on the material, material grade, printing process, etc. , and can be identified by burning samples (wallpaper with high environmental protection grade has no burning smell and smoke, and ash is gray powder) and smell (PVC wallpaper has obvious plastic smell, while wallpaper with low grade has strong ink smell). The newly rolled pulp wallpaper has no peculiar smell and the highest environmental protection level.
Consumers are advised to specify brand wallpaper accessories when purchasing wallpaper, and have authoritative environmental protection signs and testing certifications such as "China Green ten ring Certification", "EU SVHC Environmental Protection Testing" and "SGS", so as to avoid troubles in the later stage of home improvement and ensure family health through environmental protection!
