As we all know, the most suitable time of year to remove formaldehyde is summer. Because the temperature in summer is generally above 25 degrees Celsius, and the boiling point of formaldehyde is only 19℃, the higher the temperature, the faster the volatilization rate. In addition, the air quality is good in summer and is suitable for ventilation, so summer can be called the "golden season" for formaldehyde removal. It is now halfway through September, and there is only one tail left in summer. If you don’t work hard to remove formaldehyde, you can only "priming" under the heating baking in winter. After all, the lethality of smog is not small, and the ventilation conditions in winter are not as good as they are now.
Want to make good use of the last time to quickly remove indoor formaldehyde. Is there still a chance now? Of course, there is, but in order to ensure the efficiency and effect of formaldehyde removal, comprehensive measures are essential.
First of all, the most important thing to do is of course continuous ventilation . Ventilation is the most reliable, effective and harmless method to remove formaldehyde. During the ventilation process, you can open all cabinets, , drawers, and wardrobe. Especially around noon when the temperature is the highest, ventilation for 1 hour can reduce the formaldehyde concentration by 66% or even more. Of course, you can also consider installing fresh air system , but considering the price of the fresh air system, everyone can do it within their means.
Regarding ventilation, there is also a method of stuffy release. This method first closes the doors and windows for two or three days, creates a closed environment, and then ventilates for a few hours, repeating it seven or eight times. It is said to be more effective than continuous ventilation, but in fact, this method is not effective.
In fact, if you think about it carefully, you will understand that if the indoor formaldehyde concentration is close to infinite, the formaldehyde release space in the board will become smaller and smaller, which will eventually lead to the efficiency of formaldehyde release becoming lower and lower. Instead, it is better to continue ventilation and discharge the released formaldehyde at any time.
Secondly, if conditions permit, use biological enzyme spray to catalyze formaldehyde free from air. Many people in China have never heard of the word biological enzyme . Let me explain it here that biological enzyme is a non-toxic, harmless, environmentally friendly biocatalyst . Its chemical essence is a biologically active protein. Under the catalysis of biological enzymes, formaldehyde can quickly decompose into carbon dioxide and water, without causing secondary pollution. It is precisely because of this characteristic that biological enzymes have been widely used abroad. In recent years, there have been more and more biological enzyme products in China. For example, the FS complex biological enzyme products produced by Forsy Biotech can play a role under room temperature and have a good effect in removing formaldehyde.
Why recommend biological enzymes instead of photocatalysts? Because the photocatalyst requires sufficient sunlight to take effect, and the lighting conditions in general homes are not ideal, the aldehyde removal effect of the photocatalyst is not good in this case.
Finally, it is recommended to place more green plants indoors , and there is no big restriction on plant varieties. Although plants have very limited adsorption capacity to formaldehyde, fortunately, plants will not cause secondary pollution like activated carbon. Cooperating with continuous ventilation, it can not only purify indoor air, but also play a good decorative role.
Conclusion: The release of formaldehyde is a slow and long-term process. It usually takes 3-15 years to evaporate. Don’t think that one or two treatments can be completely removed. Even a professional aldehyde removal company can only solve temporary problems. In summer when the temperature is high, the volatilization of formaldehyde in the indoor air has the highest concentration. Through long-term ventilation, most of the formaldehyde in the room is removed, and then the residual formaldehyde in some confined spaces and furniture boards is catalyzed by using biological enzyme sprays. Finally, the adsorption of green plants can ensure that the indoor formaldehyde concentration reaches the safety standard.
