Formaldehyde is a highly toxic substance. Short-term exposure will cause symptoms such as hot eyes and respiratory allergies. Long-term exposure will increase the possibility of cancer. Many people are afraid to move in immediately after the renovation, because they are worried that the newly renovated house will release formaldehyde. In order to shorten the ventilation time and move into the small home of their hearts as soon as possible, many people will also try a lot of 'aldehyde removal' that is spread in the circle of friends Dafa~What kind of grapefruit peel, white vinegar, and black tea come together? Are these earthen methods really useful?
As a kind of gas, formaldehyde can be removed by the following methods:
1. Open windows for ventilation
Ventilation is the primary method to reduce the content of formaldehyde, allowing indoor air to circulate, thereby reducing the content of harmful substances in the room. This method saves money and is more environmentally friendly.
2. Physical adsorption method
Activated carbon is an internationally recognized drug addict, activated carbon masks and gas masks all use activated carbon . Generally, the activated carbon package placed in a special room uses the physical properties of activated carbon to deodorize and detoxify, without any chemical additives, and has no effect on the human body. Put two to three dishes in each house, 72 hours can basically eliminate indoor odor.
Maya blue has a selective attraction for nano-scale molecular adsorption.
Formaldehyde is a gas compound with a nanometer diameter, which is more harmful and toxic, so the unique adsorption characteristics of Maya blue in this regard are very valuable.
3. Optical method
The principle of photocatalyst removal of formaldehyde is because the catalyst contained in it will generate negative ions and oxygen with oxygen and moisture under the stimulation of light. Hydroxyl radicals, these substances can oxidize pollutants such as formaldehyde to generate harmless substances such as carbon dioxide, water and corresponding acids, thereby purifying the air.
4. Plant absorption method
Plant deodorization method can remove formaldehyde smell and give you a warm and healthy environment~cactus, spider plant, ivy, etc. It's all people's choice. It should be noted that this method is only suitable for general low- and medium-level formaldehyde pollution, and there is no evidence that plants can really absorb formaldehyde. You can use it in combination with physics or law.
5. Folk soil method
Soaking black tea with hot water, adding vinegar or grapefruit peel and orange peel to cold water can remove formaldehyde to a certain extent The gas is pungent, but these cover-ups are like perfume to treat the symptoms and not the root cause.
Actually, if the house has just been renovated and it is not clear whether the formaldehyde exceeds the standard, you can ask a testing agency to check it before you can live if everything meets the standard.
