Simply using ventilation to remove the formaldehyde concentration in the house is far from enough. Perhaps many people know that the decoration materials contain a lot of formaldehyde, but few people know that the volatilization time of hazardous substances in formaldehyde is as long as 15 years, which is why even after ventilation for more than half a year, the formaldehyde concentration in the home is still so high.
In fact, as long as the method is correct, formaldehyde in the home can be easily removed. You should know that the physical property of formaldehyde is that the higher the temperature, the faster the evaporation speed. Therefore, when a new house decoration is completed, the doors and windows must be closed for 3 days first, the purpose of this is to prevent the temperature in the house from being lost. If you still want to speed up, you can also open a few "small suns" at home to make the temperature in the home higher, the formaldehyde in the material can quickly volatilize.
You know, in this way, it only takes 3 days to volatilize more than half of the formaldehyde in the house. After that, if we ventilate again, A better effect can be achieved. It is well known that putting green plants, putting activated carbon and so on are all very good methods to remove formaldehyde.
High-end brands of doors and windows remind you that in addition to formaldehyde, you must close the doors and windows for 3 days and then ventilate them! Don't open the window first.
