For many people, is the newly decorated house a new look, which makes people feel very happy? But recently, a 5-year-old girl suffered from leukemia because the formaldehyde in her house has not been removed for 7 years, which is worrying. So what should we do if the formaldehyde in the newly decorated house exceeds the standard?
Generally, the cycle of toxic gas activity is 1-10 years, especially in the first year. During this period, the toxic gas volatilizes rapidly and releases a high amount, so the harm to human body is more serious. Excessive formaldehyde in the room is quite harmful to people's health, so we must take appropriate measures to reduce the formaldehyde content
1. Ventilation method
The best way is to ventilate.
2. Plant absorption method
Plants have strong ability to absorb formaldehyde, such as cactus, Chlorophytum, reed, ivy, iron tree, chrysanthemum, etc.. Generally speaking, the effect of formaldehyde absorption of plants with large leaf surface and vanilla is better, such as Chlorophytum, Huwei orchid, etc.
3. Folk spreading method
Put tea dregs, grapefruit peel, onion slices, pineapple pieces, etc. in the newly decorated room or fumigate the whole room with white vinegar.
4. Activated carbon adsorption
Solid activated carbon has the characteristics of many pores, and has strong adsorption and decomposition effect on formaldehyde and other harmful substances. The smaller the particle size of the activated carbon, the better the adsorption effect.
5. Photocatalyst decomposition
Under the stimulation of light, the catalyst in the photocatalyst generates negative ions and oxyhydrogen radicals with oxygen and water in the air, which can oxidize and decompose various organic and inorganic pollutants, and finally degrade them into harmless substances such as carbon dioxide, water and corresponding acids, so as to decompose pollutants and purify air.
6. Chemical purification method
At present, there are two kinds of formaldehyde capture agents on the market: one is to purify the air by neutralizing formaldehyde and generating harmless substances; the other is to purify the air by sealing formaldehyde and preventing its volatilization.
