We all know that the higher the temperature, the more serious the indoor formaldehyde evaporation, but in some cases, the winter decoration formaldehyde is the most serious in spring, summer, autumn and winter, which is a little against our basic knowledge. Many newly decorated houses in autumn will not be able to measure how much indoor formaldehyde is. However, after the reduction of heating and ventilation in winter, the formaldehyde concentration may be more serious than the newly decorated houses. How to deal with formaldehyde in winter? Here is the introduction of Jinan formaldehyde treatment staff to customers and friends:
Formaldehyde has two characteristics
One is that the melting point is 19 ℃, in other words, when the temperature is over 19 ℃, indoor formaldehyde is boiling like water. In Jinan, formaldehyde removal is more active than usual, and the higher the average temperature is, the stronger the evaporation is; the other is that indoor formaldehyde has a dangerous period of nearly 3-15 years in the board, which is not to say that it is qualified in the test today, and then it is finally safe. These two characteristics make formaldehyde become air. "Diehards" in pollution.
When the temperature exceeds 19 ℃, the volatilization rate of formaldehyde from furniture increases 0.4 times every degree, especially when the temperature rises in summer or warms in winter, the emission is more intense, and the concentration even exceeds the usual 3 times.
In autumn and spring, the indoor air pollution passed the test, but in summer and winter, the formaldehyde concentration exceeded the standard. That is to say, because the indoor formaldehyde is silent in autumn and spring, and the indoor temperature reaches 19 ℃ and higher, the air temperature in autumn and spring is cool and well ventilated, so the formaldehyde concentration is low. Jinan formaldehyde detection, hot summer weather, formaldehyde volatilization acceleration, but the advantage of summer is convenient ventilation, so formaldehyde concentration will not be particularly serious.
Although it is cold in winter, most areas in China will be heated in winter. The indoor temperature of many families can reach more than 20 ℃, and there is less ventilation. Therefore, winter has become the most serious season for formaldehyde exceeding the standard.

How to prevent and control formaldehyde
The first is to use high-quality environmental protection board and adhesive before interior decoration, so as to lay a good foreshadowing for the renovation work after interior decoration. But it is not to say that the new environmental protection materials are completely free of environmental pollution, only the environmental pollution is less than the general raw materials; more environmental protection materials are used in the unit space, which will also cause formaldehyde to exceed the standard.
After decoration, we can't take it lightly because the inspection in spring and autumn is up to standard. Formaldehyde pollution is affected by season and temperature, and it is easy to happen repeatedly when the temperature is high. Therefore, we should form a good habit of regular ventilation, which is the best way to prevent and control formaldehyde.
Experiments show that 30% of free formaldehyde molecules can be removed after ventilation for more than six months. In winter, it's cold and windy, and you may not want to open windows for ventilation. In fact, this is very bad. In winter, the indoor temperature rises, formaldehyde is released actively, and the air circulation is not smooth, which will make the indoor formaldehyde content increase dramatically. Therefore, it is also necessary to open windows for ventilation in winter, especially for new houses that have just moved in, we must insist on opening windows for more than 2 hours every day, and the outdoor air is fresh from 9:00 to 12:00 every day, which is the most suitable time for opening windows for ventilation.
According to the staff of Jinan City's indoor air treatment, customers and partners introduced in detail the key professional knowledge of indoor air treatment and prevention in winter, expecting to help a large number of customers and partners in winter.
