One. What could be the cause of the odor in the computer desk?
The new computer desk may have an odor, which is normal. The odor of the desk could be from paint or the smell of glue in the wood, but both could contain formaldehyde. Especially for new computer desks, the paint odor is stronger and is released from the exterior paint. This odor is unpleasant and contains many harmful substances. If not removed, it can harm human health. Additionally, various artificial boards (particleboard, fiberboard, plywood, etc.) may contain formaldehyde due to the use of adhesives, which can also cause odors.
Two. What to do about the strong odor from the computer desk?
1、Open windows for ventilation
Currently, many households have poor indoor ventilation. Therefore, under favorable ventilation conditions, we must frequently open windows to ventilate the indoor environment, allowing harmful substances to be effectively removed. However, formaldehyde release occurs over a long period, and if formaldehyde levels exceed the permissible limit, ventilation alone may not be sufficient. It should be combined with other methods.
2、Plants absorb formaldehyde.
- Indoor placement of various green plants can ① enhance the office environment and improve aesthetics, and ② purify the air. Many plants, such as hanging orchids, aloe vera, and ivy, also absorb formaldehyde. Their ability to absorb formaldehyde is quite effective. However, plants can only provide limited assistance in absorbing harmful substances.
3、Vinegar fumigation
Vinegar is an acidic substance that can neutralize and reduce the concentration of ammonia in the air, but it will not react with other harmful components such as formaldehyde.
4、Physical Adsorption
Activated carbon is a physical adsorbent, which is very safe and harmless to the human body. It has a small volume and can be placed arbitrarily. However, a major drawback is that it can easily become saturated and unable to adsorb, leading to contamination. Therefore, it needs to be replaced regularly.
5、Using photocatalysis to remove formaldehyde
Photocatalytic agents are one of the fastest methods for removing formaldehyde, and currently the most effective and safest method. The principle involves spraying a photocatalytic agent containing titanium dioxide onto the interior walls and furniture materials. Under the action of light, formaldehyde and other harmful substances in the air are decomposed into carbon dioxide and water. Many types are available, such as photocatalytic wood oil and leather dehydration agent, which can be used for a long time in different locations without secondary pollution.
6、Air purifier
Air purifiers can effectively adsorb formaldehyde to some extent, especially in the initial stages, but their principle is the same as that of activated carbon. However, after prolonged use, they tend to become saturated, which reduces their effectiveness.
