: Summer is due to be full of green fresh season, however, recently, the citizen Ms. Liu's home has been plagued by the smell of irritating chemicals. Ms. Liu came to the authority to test the air in the room, the results showed that the smell of Ms. Liu's home is the previous year's decoration residual pollution re-emerged.
formaldehyde is the main culprit of indoor pollution, it is a colorless harmful gas, long-term exposure may cause damage to the nasal cavity, mouth, throat, skin and hema production system and even cancer.
in the decoration process, formaldehyde is common in sheet, furniture, wallpapers, carpets,
paint
glue and other decoration materials. Because formaldehyde has a strong adhesion, at the same time can strengthen the hardness of the plate and anti-worm, anti-corrosion capacity, so the current market of various decoration materials, are inevitably used to contain formaldehyde.
general new room decoration ventilation and dispersion for more than 6 months to stay, but this does not mean that the pollutants completely scattered. National indoor indoor environmental protection product quality supervision and inspection center Song director told reporters that furniture, sheet, wallpaper, formaldehyde and other pollutants release is a long process, it takes three to 15 years or more to fully release clean. The release of formaldehyde is greatly affected by temperature and humidity, the greater the temperature and humidity, the more formaldehyde volatile, so indoor pollution in summer will be more serious than usual.
is the season with the largest release of pollutants such as formaldehyde and toluene, and is also the best season for removing pollution. Here are some methods suitable for summer deformaldehyde:
summer temperature is high, suitable for more window ventilation, ventilation can not only introduce fresh air, but also eliminate harmful gases indoors. However, the ventilation method also has shortcomings, there are often a lot of poor ventilation dead ends, due to different window shapes, indoor layout environment different areas of these dead corners can reach 30%-65% of the total indoor area, that is, 30% to 60% of the pollution can not be excluded from the outdoor ventilation method. However, ventilation method is still an effective measure to remove formaldehyde.
Some natural mineral materials have the ability to absorb formaldehyde, toluene and other harmful gas molecules, the commonality of these materials has a pore structure, pore size is nanoscale, pore diameter and formaldehyde molecular diameter is similar, and has a weak electrical properties, can be very good adsorption and lock harmful gas molecules. Common physical formaldehyde materials include Mayan blue, activated carbon and so on. In view of the current market for activated carbon is more chaotic, when buying please pay attention to counterfeit non-conforming products. Be sure to choose products with vacuum packaging.
a catalyst for photocatalysts, meaning it can promote the reaction of other substances without changing itself. When faced with light, the photocancer is able to continuously release hydrogen-oxygen free-forming and super-oxygen anions, breaking down all volatile harmful organic matter in space into trace amounts of harmless substances such as carbon dioxide and water. Different phototalytic products have different uses, but can achieve the role of deformaldehyde, such as phototapic wood essential oil can be used on flooring and wood furniture, leather deformaldehyde care liquid can be used in sofas and other leather products.
plants can absorb trace amounts of formaldehyde, but in the process, formaldehyde will cause some damage to the cellular tissue of the plant, and the absorption of formaldehyde by plants is very small, not enough to affect the indoor environment. Therefore, although plants can absorb formaldehyde, this method is not recommended.
