Identifying wallpaper quality has a coup
Compared with paints, wallpapers can be more and more popular with consumers through the wide variety of textures, colors and patterns that highlight the tastes and preferences of consumers and create a unique style of living. At the same time, with the improvement of consumer awareness of energy conservation and environmental protection, wallpaper manufacturers have also continuously claimed to improve the production process, using environmentally friendly paper base, and even some manufacturers claim that the product is "zero formaldehyde." Is the wallpaper really as reassuring as the business promotion? Our reporter found that the actual situation is not satisfactory. After smashing the wallpaper, the smell is pungent Not long ago, the China Consumers' Home Safety Survey conducted by the newspaper showed that 88% of respondents had experienced home safety problems, and the health problems caused by poor air quality accounted for 16%. Industry experts pointed out that the environmental protection of wallpaper is one of the important reasons for the excessive indoor air quality, but many consumers are not aware of this. Mr. Li, a consumer who lives in Shenyang, pays special attention to environmental performance when purchasing decoration materials for new houses. He heard that wallpapers are more environmentally friendly than paints, so they bought a brand wallpaper. However, after a few days of wallpapering, he found an unpleasant smell in the house. "There is no strange smell in the home before the wallpaper is attached, and the construction is strictly in accordance with the requirements of the merchants. Why is there a pungent smell?" Mr. Li is very puzzled. Ms. Yan of Qingdao (real estate) spent 9,000 yuan to buy a wallpaper that claimed “zero formaldehydeâ€. She told reporters: “Although this wallpaper is more expensive than the average wallpaper, the salesperson claims to be absolutely environmentally friendly and formaldehyde-free. I did not expect After the wallpaper was posted, there was a pungent smell in the home. After testing, it was found that the indoor air formaldehyde concentration exceeded the standard by 3 times. According to Ms. Yan, the rubber free formaldehyde used in the wallpaper construction was not detected by the Qingdao Municipal Product Quality Supervision and Inspection Institute. qualified. Material, craft, and glue determine whether it is environmentally friendly. “A lot of friends around me use wallpaper to decorate the room, so the house that is decorated is more individual.†The 80-year-old Beijing (real estate) girl Mai Qing, who is busy with the renovation of the new house, was interviewed by reporters. Say. When reporters visited the home stores in Beijing, Jimei and other home stores, they found that the wallpaper products were dazzling, and the price gap was quite large, ranging from tens of yuan to several hundred yuan per roll. The manager of a wallpaper brand store told reporters: "Now the wallpaper market is too chaotic, consumers can't distinguish the quality with the naked eye, don't believe that the price is expensive, the imported is a good wallpaper, it is recommended that consumers still want to buy famous brands. "The product of zero formaldehyde only means that its formaldehyde content is lower than the testing standard, and it is not really without formaldehyde. Now it is impossible for any manufacturer to achieve zero formaldehyde." Xu Gang, director of the China Wallpaper Association, told reporters that the pollution of wallpaper mainly comes from the release of volatile organic compounds, namely formaldehyde. There are two main reasons for the formation of formaldehyde: one is that the raw material hydroformylation process and the aldehyde-reducing process may leave some free formaldehyde; the other is that the adhesive used in wallpaper contains free formaldehyde. Because the environmental performance is invisible and intangible, many small manufacturers only care about whether the wallpaper is good in color and color, and does not consider environmental factors. In addition, in order to pursue the stereoscopic effect of the wallpaper, some manufacturers will use ink and other non-environmental materials in the wallpaper processing process, which makes the wallpaper have environmental protection safety hazards. In addition to the material, the production process also directly affects the environmental performance of the wallpaper. Yang Yuan, general manager of Grammy, said that the same material, if the production process is not closed, there will be a phenomenon of environmental protection. “The temperature of the drying box is unstable and the equipment is not advanced enough to directly determine the environmental protection level of the wallpaper.†Yang Yuan pointed out that the most advanced technology is to dry the volatile substances in the wallpaper through the drying box at one time. Then pass the positive and negative electrolysis to ensure the stability of the wallpaper. According to industry insiders, in order to make the product have better permeability in the production process, wallpaper glue usually uses a large amount of volatile organic solvents, which will release harmful substances such as formaldehyde, benzene, toluene and xylene. At present, most of the glues used by brand manufacturers on the market are more environmentally friendly, but the quality of the glue used by many small manufacturers is unknown. Identifying wallpaper quality has a coup In fact, most consumers know little about wallpaper, so how to choose wallpaper? Xu Gang introduced three methods to consumers. First, the fire method. If the merchant says that the wallpaper is made of natural materials, then you can take a small piece of wallpaper and burn it with a lighter. Naturally textured wallpapers are basically smoke-free after burning, without a pungent odor. Ashes are gray powders, like burning paper or burning cotton, rather than a piece of black char. If the wallpaper smells very pungent after burning, it means that the environmental performance of the wallpaper is not enough. PVC wallpaper has a distinct plastic taste after burning, and the low-grade wallpaper has a strong printing ink smell after burning. Second, the wiping method. The colorful wallpapers are beautiful, but don't forget to wipe them with a damp cloth before buying to see if they are discolored, especially some wallpapers with bumpy textures. In the future, you can often clean and care, and the wallpapers with poor stain resistance or It is not easy to clean, or it is easy to scratch the surface when cleaning. Third, the soaking method. Cut a piece of wallpaper and soak it in the water. After 12 hours, if the wallpaper does not appear layered or faded, its quality will be basically qualified. After the water-resistant wallpaper is damp, it will be drum and degummed. women period pad,best menstrual pad,best sanitary pad,menstrual pad FOSHAN NICEDAY SANITARY PRODUCTS CO.,LTD , https://www.nicedayherbal.com
