Will indoor formaldehyde volatilize in winter?

Yes Formaldehyde will volatilize in winter, and the release rate of formaldehyde in winter is faster than that in other seasons. This is because in winter, whether in the north or the south, indoor heating or air conditioning will be chosen, which will make the indoor temperature higher anyway. The higher the temperature, the faster the formaldehyde release rate. The release cycle of formaldehyde is as long as 3 to 15 years, so the formaldehyde hidden indoors will be released continuously all the year round.

What factors are related to the volatilization rate of formaldehyde?

1.？ indoor temperature

Indoor temperature is the biggest factor affecting indoor formaldehyde volatilization rate, and the most difficult thing to remove indoor formaldehyde is bound formaldehyde. When the indoor temperature rises, bound formaldehyde will release free formaldehyde into the air at a higher rate, and the indoor formaldehyde concentration will also increase. Especially in winter in the north, due to the cold weather, indoor heating will greatly accelerate the volatilization of indoor formaldehyde, as will air conditioners in the north, and air conditioning heating will also affect its release speed.

2.？ Indoor humidity

Indoor humidity will also affect formaldehyde volatilization from pollution sources, mainly because the adhesives in decoration materials such as furniture and wood-based panels are composed of urea and formaldehyde. When the board and furniture are wet or the indoor humidity increases, the glue will decompose a lot of formaldehyde with water at this time. Therefore, when indoor formaldehyde is humid or the weather is frequent and rainy, the relative humidity of indoor air is high, the release speed of formaldehyde is accelerated, and indoor formaldehyde may also face the risk of exceeding the standard.

3.？ Air circulation

The change of indoor air will also affect the volatilization speed of formaldehyde, because indoor air is always in a state of dynamic balance. If the doors and windows are closed for a long time, the indoor air will not circulate, and the formaldehyde accumulated indoors will reach the threshold, so the formaldehyde will no longer be released. When the window is opened for air circulation replacement, the original formaldehyde will circulate to the outside, and the indoor formaldehyde will be released quickly, reaching the original threshold again. Therefore, the circulation of indoor air also has a great influence on the release speed of indoor formaldehyde, so window ventilation is a very good method to remove indoor formaldehyde.

The temperature is generally higher in summer and higher in winter under heating conditions, and formaldehyde is released faster in these two seasons. So apart from formaldehyde companies, in addition to formaldehyde is more efficient in these two seasons. In terms of relative humidity, winter is relatively dry, and the indoor humidity is certainly not as high as other seasons, but this is not the main factor affecting the formaldehyde release rate. Window ventilation can be done at any time, just pay attention to the weather changes to prevent the destruction of indoor decoration by bad weather.
