Formaldehyde VOC Emission Environmental Chamber Formaldehyde Emission Introduction

Similarly, the formaldehyde VOC emission Environment Chamber has different formaldehyde emission in the same room under different temperatures and closed for 12 hours. For example, in the verification test, the formaldehyde content in the bedroom exceeded the standard by 0.24mg/m3 at room temperature of 28.8℃, but reached 0.09mg/m3 at room temperature of 23.7℃, which was up to standard. The same is true for the living room.

So we can draw a conclusion about the formaldehyde release temperature:
The formaldehyde release temperature is -19.5℃. Formaldehyde is released at any time under normal temperature. However, the formaldehyde emission is lower when the formaldehyde is lower than 19 degrees Celsius. It is accelerated when it is higher than 19 degrees Celsius. 19℃ is more like a turning point for formaldehyde release acceleration.
At the same time, the whole test process also verifies the characteristic that the formaldehyde emission increases with the increase of temperature.
What is the use of knowing at what temperature formaldehyde is released?
1. The release of formaldehyde can be accelerated by increasing the temperature before moving in, which is also the principle of some treatment companies using high-temperature fumigation;
2. Now you should understand why the formaldehyde content detected in winter is lower and why it is higher in summer. Therefore, customers who have passed the winter test are recommended to retest again after the summer comes.
