1, put salt water (vinegar) in the new house.
Many people say that water can absorb formaldehyde. In fact, this statement is not entirely correct. It is necessary to add some salt or vinegar to the water to absorb formaldehyde in the air and remove the pungent smell in the new house.
2. Indoor ventilation
Formaldehyde is a volatile substance, so after the renovation of the new house, all the doors and windows outside the entrance can be opened for ventilation, so that the volatile formaldehyde can be taken away by the indoor wind, thus achieving the purpose of in addition to formaldehyde. However, this method takes a long time. After all, formaldehyde volatilizes too slowly and can be hidden for more than ten years.
3. Increase the indoor temperature.
Because the speed of formaldehyde volatilization is extremely slow, we can increase the indoor temperature to promote formaldehyde volatilization, so combined with ventilation method, formaldehyde in new houses can be quickly removed.
4. Activated carbon
Activated carbon has a good adsorption effect, whether it is impurities in water or air pollution, odor and so on. , can be improved. However, if formaldehyde is adsorbed by activated carbon, attention should be paid to the amount, and it is best to put about 50g of activated carbon per square meter, which can effectively remove formaldehyde and pay attention to replacement after saturation.
5. Green plants
There are many plants in nature that can purify the air, and many of them can absorb formaldehyde, such as chlorophytum, Hupilan, cactus and so on. , are good helpers to absorb formaldehyde. Even after moving into a new house, you can put some plants indoors to prevent formaldehyde from volatilizing in the later period, and plants can also decorate the space.
6. Photocatalyst
With the problem of formaldehyde being concerned by more and more people, many new in addition to formaldehyde methods have appeared in the market, among which the photocatalytic decomposition method can remove formaldehyde quickly and safely. As long as some furniture surfaces and walls with high formaldehyde content are sprayed with nano titanium dioxide liquid products, formaldehyde can be oxidized and decomposed into carbon dioxide and water without causing secondary pollution.
