Diatom mud wallpaper deformed formaldehyde effect is difficult to guarantee

News: With the enhancement of people's awareness of environmental protection in home, more and more businesses see business opportunities, so it is said to be able to remove formaldehyde diatom mud wallpaper, flooring and other products have entered the market, to the consumer's wallet beckoning. But experts caution that such products with purification function, even if effective, can only play a supporting role, consumers must not be superstitious. "Home Assistant" column specifically for this series of reports, I hope to help you.
reporters in Tmall Breathing House flagship store to see diatom mud wallpaper, the introduction said that the wallpaper with a functional layer, can be "anti-formaldehyde, de-formaldehyde." The reporter then contacted the store's after-sales staff to inquire about the performance of the wallpaper.
after-sales staff said that the diatom mud wallpaper looks the same as ordinary wallpaper, but in nonwovens added diatom mud functional layer, certainly can absorb formaldehyde, but the effect will be worse than the direct use of diatom mud. The reporter also asked whether there is a test report, the after-sales staff said they do not know whether the company has, because the wallpaper is imported, even if there is a test report is foreign.
reporters in the respiratory house official website saw its introduction: "breathing house wall material continuously and effectively absorb and decompose formaldehyde, ammonia, benzene, xylene, TVOC and other toxic substances, and no longer released ... The formaldehyde adsorbed by the breathing roof material binds to oxygen to produce foric acid, which is eventually broken down into carbon dioxide and water. "
reporter visited the homewear market found that many businesses are around formaldehyde to do articles. But song Guangsheng, director of the National Indoor Environment and Indoor Environmental Protection Product Quality Supervision and Inspection Center, said that although formaldehyde has a large impact and sustained release time, indoor air pollutants are not just formaldehyde. The problems of benzene, TVOC, radon, ammonia and radioactive pollutants in the room cannot be ignored.
some consumers believe that as long as the purchase of products with purification function, you can bid farewell to indoor pollution from this peace of mind. But experts point out that the use of decorative materials with a certain air purification function is good for regulating the indoor environment, but it is not realistic to rely on it to completely eliminate indoor air pollution. For example, indoor formaldehyde release is higher than the absorption rate of diatom mud, so indoor pollution is simply not cleared. The best way to reduce indoor air pollution is to open the windows and ventilate every day.
Zhijiang, director of the Environmental Functional Materials Research Office of the China Institute of Building Materials Science Research, suggests that if you want to control indoor air pollution, it is best to try to select building materials with good environmental performance during decoration. In addition, we should pay attention to the superimposing effect of pollutants. Song Guangsheng suggested that we should not over-decorate in order to fundamentally control pollutants. In addition, he suggested that owners who are particularly interested in indoor environments can ask professional bodies to conduct comprehensive testing of indoor air quality after the renovation is completed.
Zhai Zhijiang said that the ecological wall material of diatom mud is required to be a certain thickness to function, to make wallpaper functional layer, for the environment will certainly be worse. In addition, since it is claimed to be a diatom mud product, the proportion of diatom mud composition should be clearly indicated.
As to whether formaldehyde will eventually break down into carbon dioxide and water after absorption, Zhai Zhijiang said that diatom mud can absorb formaldehyde, but formaldehyde will continue to decay after adsorption, as to what kind of substances will be reacted to in the future, it is still unknown.
