Some reporters interviewed the dean of the College of Materials Science and Engineering of Northeast Forestry University and Gu Jiyou, a doctoral supervisor, in response to the fact that some citizens had formaldehyde levels exceeding the standard at the first inspection of the floor and the second test after more than two months was qualified. professor. Professor Gu Jiyou pointed out that the formaldehyde content in the floor will decline with the passage of time and the flow of air. Therefore, ventilation is a key task that must be done by the public after housing renovation and before arrival.

Prof. Gu Jiyou said that the amount of formaldehyde released from the floor was exceeded two months ago. After more than two months of ventilation, the content of toxic gases such as formaldehyde in the floor will be reduced. This is normal. After the decoration of the public, the house must be ventilated for a period of time to stay. Because the decorative materials not only contain formaldehyde, but also contain some other harmful substances and toxic gases, they will continue to be released, posing a threat to human health. If the content of formaldehyde in the floor exceeds the national standard, after a period of ventilation, the public can also buy some formaldehyde trapping agents in the market to manage the indoor environment, so that formaldehyde in the floor or furniture can be effectively removed. After this treatment, the formaldehyde content can be detected again. If it is qualified, it can be checked in, otherwise it can not stay. The public can repeat the above methods to control pollution sources. They can also dismantle the floor or remove furniture and take other solutions.
Prof. Gu Jiyou pointed out that it is important to emphasize that the windows of the renovated house should be closed tightly before the ventilation of the windows, and the weather should be increased as much as possible to keep the room temperature high. This is beneficial to formaldehyde and other harmful gases from the floor and furniture. Released as soon as possible, and then open the window convection ventilation, which will help formaldehyde and other harmful substances in the indoor air and toxic gases discharged as soon as possible, so repeated several times, the effect will be better. There is also a method of removing formaldehyde, which is to use ammonia or activated carbon and other materials to dry the decoration materials. For several days, it can also effectively remove formaldehyde from the floor or furniture. However, after a period of time, the formaldehyde content may be A certain degree of rebound.
A few days ago, when people from the same floor manufacturer went to the consumer Liu's home sampling board, she saw a lot of activated carbon on the floor of each room. Ms. Liu told reporters that since her house was completed, she bought a lot of activated charcoal and placed it on the floor of her home. In addition, she also adopted a convection ventilation method. It is reasonable to reduce the formaldehyde content of the floor at home. thing. However, she is still worried about the magnitude of the decline in the results of the re-examination and is afraid that the formaldehyde content will rebound. She prepared to remove the formaldehyde from the gap at the side of the floor while the manufacturer restored the original floor, to prevent future problems and ensure safety afterwards.
