Many people move in to live in a new house just after the renovation, but did you know? The newly renovated house cannot be moved in immediately, because the materials used to decorate the house emit toxic and harmful substances such as formaldehyde and benzene. Long-term exposure to these low-dose toxic and harmful substances can cause dizziness, eye pain, nausea, vomiting and many other uncomfortable symptoms. In severe cases, it can cause nasopharyngeal cancer, laryngeal cancer , leukemia, etc.
Since the newly renovated house is so harmful, how long do we have to put it aside? In fact, there is no fixed standard time, because it is related to the decoration materials you choose. If you choose environmentally friendly materials when decorating, the release of toxic and hazardous substances will be relatively small, and the check-in time will be earlier. If ordinary non-environmentally friendly materials are selected for decoration, the shelving time will be appropriately extended.
In addition, it is also related to the season. In the spring and summer, due to the rain and high humidity, the indoor air convection is slow, and the shelving time will be prolonged. In autumn and winter, the air is dry, indoor air convection speeds up, indoor toxic and harmful gases are quickly discharged, and the shelf time can be appropriately shortened.
Before moving in, we can first detect the formaldehyde content in the indoor air. When the indoor formaldehyde content is lower than the national II civil building occupancy standard 0.1mg/m3,Explain that it meets the occupancy standards, you can move in. If the test result is higher than this standard, we also need to adopt some methods of removing formaldehyde to reduce the indoor formaldehyde content, and wait until the occupancy standard is reached before moving in.
The following are some commonly used indoor formaldehyde removal methods, which can help you shorten the shelving time and move into a new house earlier.
uses ventilation methods other than formaldehyde.
After the new house is renovated, it is necessary to frequently open windows for ventilation, maintain indoor and outdoor air circulation, effectively improve the indoor air quality, and let the air discharge harmful gases to the outdoors through convection. Although this method is effective, it also has a disadvantage. It is easily affected by weather and seasons. When the air humidity is high in rainy days and spring and summer, the effect of removing formaldehyde is not ideal.
Use plants to absorb some indoor formaldehyde.
If the indoor formaldehyde content is not too serious, you can choose to grow green radish, spider plant, agave and other plants that can absorb formaldehyde, so that while absorbing formaldehyde, the beautiful flowers will also add some beauty to the home .
uses photocatalyst to remove formaldehyde.
photocatalyst is one of the most efficient and safe methods to remove formaldehyde, and it is relatively simple to use. We only need to spray the titanium dioxide liquid in the bottle directly on the wall and furniture surface,Under light conditions, using the catalytic effect of titanium dioxide, harmful gases such as formaldehyde and benzene in the air will be decomposed into non-toxic carbon dioxide and water, thereby achieving the effect of purifying indoor air.
uses activated carbon to adsorb formaldehyde.
Activated carbon uses the principle of physical adsorption to adsorb formaldehyde in the air. It is very safe and harmless to the human body. However, ordinary activated carbon is easy to saturate and needs to be replaced regularly.
uses an air purifier to filter formaldehyde.
air purifier has a strong effect of purifying the air. It can simultaneously remove formaldehyde, benzene, TVOC , haze and many other toxic and harmful substances in the air, making indoor air fresh and natural, which is beneficial to our health .
In theory, the release period of formaldehyde in home decoration materials is as long as 3-15 years. After moving into a new house, long-term prevention and control of formaldehyde must be done to prevent the indoor concentration from rebounding and endangering the health of family members.
