Will formaldehyde volatilize more at high temperature?

The volatilization of formaldehyde is closely related to temperature. Generally speaking, the higher the temperature, the easier it is for formaldehyde in furniture to volatilize. Hot summer is the most "rampant" season for formaldehyde volatilization: high temperature weather directly leads to indoor formaldehyde release 20% to 30% higher than usual; Every time the room temperature rises 1℃, the formaldehyde volatilized from wooden furniture and floors will increase the formaldehyde concentration in indoor air by 0. 15-0.37 times.

An experiment shows that when the room temperature rises to 30℃ and the indoor relative humidity is 45%, the formaldehyde emission concentration in the air is 0.223 mg/m3, which is 2.23 times higher than the national indoor air quality standard. When the room temperature rises to 34℃ and the relative humidity is 50%, the formaldehyde emission concentration exceeds the standard by 5.53 times.

Extended data:

Avoid indoor formaldehyde pollution in summer;

1, treated with air purifier.

If the concentration of pollutants such as formaldehyde is too high, you can buy an indoor air purifier for treatment. Treatment methods include chemical decomposition, molecular sieve filtration, activated carbon adsorption, negative ion catalysis, etc. Some use wax sealing to seal the surface of furniture in order to inhibit the release of harmful gases.

Put the new furniture for a while before using it.

Don't rush to put the newly bought furniture into the living room. If possible, it's best to put it in an empty room and use it later. Newly renovated families have bought new furniture, so it is best not to move in in a hurry and let the harmful gases in the furniture be released as soon as possible.

Also pay attention to the quilt placed in the wardrobe in summer, which will absorb a lot of formaldehyde and must be fully dried before use. Fabric sofa should not only pay attention to fabrics, but also pay attention to fillers. The filling material should be solid and elastic, and can rebound quickly after pressing, leaning, squeezing and releasing pressure, without pollution.
