Does painting walls contain formaldehyde?

Paint will be used to paint the walls during renovation. Paint is made of many kinds of materials. Some paints are less harmful to the human body, while some paints are harmful to the human body because some paints contain formaldehyde. Therefore, when choosing paint, it is better to choose paint with better quality. After the house is decorated, you must pay attention to the elimination of formaldehyde. Some methods can be used to remove formaldehyde. Is there formaldehyde in painting the walls? Let's take a look.

Nowadays, the paint for wall painting can generally be latex paint, oil paint, and diatom mud. Of course, wallpaper can also be used as wall decoration materials, but it is not paint that is pasted on. Latex paint contains formaldehyde, and some oil paints contain formaldehyde, while others do not. Wuhan Lanshe Diatom Mud tells you that only diatom mud is the interior wall paint that does not contain formaldehyde, and it can also absorb and decompose formaldehyde.

2. How to remove formaldehyde during decoration?

1. It is best not to move into a newly renovated house for the time being, because the first year after home decoration, especially the first six months, is a period of strong release of harmful gases such as formaldehyde and benzene.

2. When the indoor formaldehyde content exceeds the national standard by less than 1 times, you can use daily forced ventilation and plant flowers and plants with a certain formaldehyde removal ability, such as spider plants, to solve the problem. Another good method is to place activated carbon or bamboo charcoal, but these methods act on harmful gases in the indoor air, not on the pollution source, so they are suitable for situations where the content of harmful gases such as formaldehyde is small.

3. When the indoor formaldehyde content exceeds the national standard by more than 1 times, it is necessary to remove the formaldehyde from the source.

3. Methods for removing formaldehyde

1) Plant absorption

Harmful gases in the air can be absorbed by growing plants, or they can be oxidized and decomposed by microorganisms and enzymes.

Tips for removing decoration pollution. Aspidistra and Monstera can remove harmful substances in the air, while Tiger Chlorophytum and Chlorophytum can absorb 20% of the indoor

The above formaldehyde and other harmful gases; aloe vera is a good absorber of formaldehyde, Milan, wintersweet, etc. can effectively remove sulfur dioxide, carbon monoxide and other harmful substances in the air; the cilia of plants such as orchids, osmanthus, and wintersweet can intercept and absorb floating particles and smoke in the air. Ivy and cycads can effectively absorb indoor benzene, spider plants can "swallow" indoor formaldehyde and nitrogen peroxide, and arisaema can also absorb 40%.

of benzene, 50% of trichloroethylene. The volatile oils in the scent of flowers such as roses, osmanthus, violets, jasmine, and carnations also have significant bactericidal effects.

It uses natural light energy to catalyze and decompose various harmful gases such as formaldehyde and benzene, just like photosynthesis.

The main ingredient, titanium dioxide, is very safe and can be added to food and cosmetics in trace amounts. There are many brands on the market now, and Japan has relatively good development in photocatalysts.

3) Remove formaldehyde hazards by activated carbon or bamboo charcoal adsorption

Activated bamboo charcoal is internationally recognized as an expert in absorbing drugs. Activated bamboo charcoal masks and gas masks all use activated carbon. This product utilizes the physical effect of activated carbon to deodorize and remove toxins; it does not contain any chemical additives, has no effect on the human body, has slow adsorption, and is easily saturated. There are many kinds of activated carbon, including coconut shell charcoal, fruit shell charcoal, coal-based activated carbon, etc.

4) Chemical removers

Chemical removers can act on the source of formaldehyde pollution and basically solve the formaldehyde pollution problem. It is a very good product with a single targeting.

The air purifier can not only humidify the indoor air, but also play a very good role in improving the indoor environment when the indoor air is slightly polluted.

Formaldehyde removal is a slow process (the formaldehyde release period in home decoration is generally 3 to 15 years). In case of human contact, rinse with water. If there is formaldehyde in the working environment, you can wear a gas mask. Try not to use too many decorations in your home decoration. Simplicity is beauty.
