Misunderstandings in the governance of formaldehyde

After the decoration of the new house is completed, the follow-up pollution control issues cannot be taken lightly. Especially the treatment of indoor pollution must be taken seriously.
According to the data survey, indoor air pollution is 2-3 times more serious than outdoor air, and 68% of human diseases are related to indoor air. The main cause of pollution is pollution from furniture and interior decoration-formaldehyde, benzene, TVOC, ammonia When toxic and harmful gases exceed standards, formaldehyde is the culprit.
Formaldehyde is toxic and will affect human health if it is used for a long time. Formaldehyde is highly irritating and can cause irritation to the eyes, skin and respiratory system. Long-term exposure to excessive formaldehyde can easily cause contact dermatitis, asthmatic bronchitis, and some allergic diseases. It can also cause coma and shock in severe cases.
At present, there are still many misunderstandings in the treatment of formaldehyde, such as:
1.window ventilation
The principle of removing formaldehyde by the ventilation method is very simple, that is, ventilation to promote air flow, thereby exhausting harmful gases such as formaldehyde to the outside, to achieve the purpose of pollution control.
However, the ventilation method is slow in treating formaldehyde pollution, and because the density of formaldehyde is greater than the density of air, it is easy to precipitate. Even if the window is ventilated, the formaldehyde is still difficult to remove completely.
2. Remove formaldehyde from grapefruit peel and pineapple peel
Yuzu peel and pineapple peel both have their own unique fruity aroma, rich and long-lasting flavor, refreshing.
In fact, they can't remove formaldehyde, they just cover up the smell of formaldehyde with their own taste, they can't remove formaldehyde and other harmful substances, it is a way to hide their ears.
3. Green plants remove formaldehyde
In fact, formaldehyde can react with plant proteins, nucleic acids and lipids, harm plant cells, and severely cause plant death. In an environment containing a large amount of formaldehyde, the plants themselves are not guaranteed, let alone help humans to remove formaldehyde.
4.Removal of formaldehyde by chemical reagents
At present, a large variety of formaldehyde scavengers on the market are mostly purified ingredients. It is a drug that is three points poisonous, especially the cost of some inferior formaldehyde scavengers is very low. It is a chemical component harmful to the human body. Even if it can react with formaldehyde, it can not guarantee safety and health, but cause secondary pollution.
5.Removal of formaldehyde by activated carbon
In recent years, activated carbon is often seen in television programs and advertisements. Businesses claim that activated carbon has a strong formaldehyde absorption capacity. There are indeed many tiny pores in activated carbon, and formaldehyde can pass through them smoothly. However, activated carbon is easy to absorb and saturate, and it is easy to release at high temperature, causing secondary pollution. Therefore, its ability to absorb aldehydes is very limited.
