Many citizens have to worry about what decoration style to choose for a new house, but how is the air quality in the room, do you ignore it? Recently, the Suzhou Quality Supervision Department launched a free test of indoor air formaldehyde content for nearly 100 newly renovated houses in the urban area. Just the results of the statistical test have made people stunned: nearly half of the households have a situation of excessive formaldehyde.

Solid wood furniture, ventilation for several months, bedroom air å’‹ is still not qualified?

Mr. Zhou, who lives in the third phase of Jiabao Garden in Wuzhong District, signed up last month and participated in the formaldehyde measurement activity of the new quality supervision department of Suzhou. A week later, Mr. Zhou waited for the test results of the living room and the master bedroom. “The living room test results are qualified, but the formaldehyde content in the master bedroom exceeds 0.02mg/m3.” Mr. Zhou said that in order to stay safer and safer, he also specially purchased a set of solid wood furniture for the main bedroom, and the new house was renovated. After the completion, leave a few months for ventilation. Although the over-standard is not serious, it is still somewhat unreliable.

The reporter learned from the Suzhou Quality Supervision Bureau that the actual new homes of 99 families have been tested, and the pass rate is only 53.54%. Among them, 46 of them have detected different levels of air formaldehyde.

The single-piece product release amount can be used in a concentrated manner and may exceed the standard.

Yang Xi, a staff member of the Suzhou Quality Supervision Bureau, said that the use of adhesives, wood-based panels, paints, furniture and other products with excessive formaldehyde emission is the main reason for the excessive formaldehyde content in indoor air. It is also worth noting that even The release amount of formaldehyde in the products is within the national standard. If one or more products are used in large quantities, it is likely to form a superposition effect, resulting in excessive formaldehyde content in the indoor air. It takes up to 10 to 15 years to wait for the most harmful pollutants in home air pollution to evaporate completely. According to the results of the laboratory sampling test, the main reasons for the excessive formaldehyde are divided into the following categories: the completion time of the decoration is too short, the harmful substances are not completely evaporated; the purchased furniture has a large amount of formaldehyde volatilization, such as the use of poor materials. Panel furniture, or furniture with complicated workmanship and concealed bonding parts; indoor furniture space occupancy rate is too large, room area is too small, or furniture is relatively excessive; interior decoration is too cumbersome, such as ceiling, background wall, etc. Forming materials such as plates and glues containing formaldehyde; and the bedroom structure on the building is relatively compact, or the ventilation and ventilation effect of the entire suite is poor.

New house decoration, see the season selection, beware of secondary pollution of aldehydes

The inspection personnel of the quality supervision department reminded: when consumers install at home, they should use ordinary adhesives, wood-based panels, paints and ordinary panel furniture as much as possible, and choose products without irritating odor; because the indoor air of ordinary houses exceeds the standard, mainly the panel furniture The amount of formaldehyde released exceeds the standard. Therefore, when purchasing ordinary panel furniture, it is necessary to carefully check the relevant quality certificate. You can also open the cabinet door and pour the head into it. If the eyes are obviously irritated by tears, or the smell is horrible, The possibility of formaldehyde exceeding the standard is great.

At the same time, maintaining indoor air circulation is an effective way to reduce indoor formaldehyde pollution. After the renovation is completed, do not rush to check in immediately, at least first ventilate for more than 1 month, usually open the window ventilation, or use an effective air ventilator. What is particularly recommended here is that many citizens go to the renovation as soon as they get the house, and they stay in one after the renovation. In fact, it is best to carry out renovations from February to March in the spring. When the summer is completed in June and July, it will catch up with the highest temperature and humidity during the year, which is conducive to the full release of toxic and harmful gases such as formaldehyde. In comparison, the temperature is low in the autumn and winter, the air is dry, and the formaldehyde volatilization is relatively slow.

In addition, the market for a wide range of chemical formaldehyde removal products should be carefully purchased. If the public blindly listened to the introduction, the purchase of industrial aldehydes containing toxic chemical components not only failed to achieve the desired treatment effect, but would cause secondary pollution. Many formaldehyde scavenger products can only last for 5 to 7 days, while the formaldehyde pollution cycle is much longer and it is difficult to remove completely and effectively.
