My formaldehyde testing room is qualified in winter and unqualified in summer. Why?

I believe everyone knows the source and harm of formaldehyde, and its volatilization time is particularly long. If you live in an environment full of formaldehyde for a long time, it will have a certain impact on people's physical and mental health. Therefore, it is necessary to detect and deal with the formaldehyde problem in houses. So, is formaldehyde testing good in summer or winter? When is the most accurate test? Let's take a look at these questions today!

Is formaldehyde detection better in summer or winter?

Bian Xiao believes that many owners who move into new houses will have a question when they conduct indoor formaldehyde testing in winter, and there is no formaldehyde exceeding the standard. However, formaldehyde was detected in summer and found to exceed the standard several times. So, what caused this?

As we all know, the volatilization of formaldehyde has a great relationship with temperature. It is reported that the boiling point of formaldehyde is 19℃, which means that when the temperature reaches 19℃, formaldehyde is more active than usual, and the higher the temperature, the more intense the volatilization. According to statistics, when the room temperature reaches above 28 degrees, the unqualified probability increases, and when the room temperature is lower than 15 degrees, the unqualified rate decreases obviously. The incubation period of home decoration pollution is long, and the detection amount of formaldehyde in summer is many times higher than that in winter. That is to say, when the temperature of the same room reaches 30 degrees in summer, the indoor pollution level may be 3 to 7 times higher than that when the temperature is lower than 10 degrees in winter, so there will also be cases where the test results are qualified in winter and unqualified in summer.

When is the most accurate test?

Summer can be said to be the season with the highest indoor formaldehyde concentration throughout the year. If the formaldehyde detected in summer does not exceed the standard, it is generally healthy and safe to stay. However, in this small series, it is recommended that the owners who are renovating and the owners who have completed the renovation should stay in the house after at least half a year of renovation and ventilation, so as to avoid formaldehyde poisoning caused by excessive formaldehyde.

There are not only formaldehyde pollution, but also ammonia and TVOC. Newly renovated house, it is best to put it together with newly bought furniture, pay attention to ventilation at ordinary times, and then leave the house vacant for 2 to 4 months. At this time, it is the acute volatilization period of harmful gases, and the taste will be very strong. We should insist on ventilation and release harmful gases as soon as possible. Bian Xiao suggested: choose environmentally friendly materials when decorating to fundamentally remove pollution.

Through the above introduction, I believe that everyone is right about "Is formaldehyde detection good in summer or winter? When is the most accurate test? " With a certain understanding, I hope the above information can help you.
