How can the newly renovated new house be ventilated when no one lives in it?

The newly renovated new house is unoccupied. It is suggested to close the window, not only to close the window, but also to cut off water and electricity. It is said that the reason for opening the window is nothing more than the problem that formaldehyde cannot be emitted. Then let's talk about why the window should be closed and when it should be opened.

1, safe; If you don't live for a long time, you should close the window with or without furniture. The first is property safety. Secondly, you don't know when it will be windy and rainy now, so it's safer to close the window.

2. Interior decoration; Indoor latex paint or wallpaper are not suitable for opening windows for a long time. Too dry or too wet is not good.

So when do you open the window? How to reduce the pollution at home?

When you go to the new house, open all the windows at home after you go in, and then you can stay at the door for a while before you go in, because this is the time when the formaldehyde concentration in the house is the highest, so you must be fully ventilated before you go in. I have seen many netizens say that things like green plants or activated carbon are put at home, but what needs attention when putting these things is:

1. in addition to formaldehyde put activated carbon into it at home, but it will still have some effect in the early stage. Activated carbon adsorbs some substances in the air, including formaldehyde molecules, by the adsorption capacity of pores. However, because the pores of activated carbon are too large, it is very easy to adsorb and saturate. Once the adsorption is saturated, if the ambient temperature rises, the adsorbed formaldehyde will be released again and become secondary pollution; So activated carbon must be replaced for a period of time.

2. The green radish with the strongest adsorption capacity inhales only 20 micrograms of formaldehyde per hour. If a room of 100 square meters is taken as the benchmark, and the formaldehyde standard of the whole room is reduced to the standard range of 0.08, then 1800 pots of green radish need to be placed at the same time! It is also necessary to ensure that no new formaldehyde is released during absorption. Therefore, plants only play an auxiliary role in in addition to formaldehyde.

Therefore, for formaldehyde, the release period is as long as 3 to 15 years, and the only way is in addition to formaldehyde and ventilation.

There is also a radiation factor in the stone used in many places at home.

I wonder if this will help you. After the renovation of the new house, it is necessary to open the window for ventilation, but it is better to close the window for a long time.
