Plant absorption method
Plants have a strong ability to absorb formaldehyde, such as chlorophytum, Huwei orchid, ivy, aloe, agave, hibiscus, cactus, Clivia, cycad, chrysanthemum and so on.
Many plants do have a certain air purification effect. But this does not mean that plants can completely remove formaldehyde from the air, and the absorption of formaldehyde by plants can only play an auxiliary role in the whole process of purifying the air. If the formaldehyde content in the air is too high, it may even lead to the death of the plant itself. In addition, because they consume formaldehyde around them through photosynthesis, the absorption efficiency will be very low at night and in rainy weather.
Folk soil circulation method
Put tea residue, grapefruit peel, onion slices, pineapple pieces, etc. In a newly renovated room or fumigate the whole room with white vinegar.
In fact, using tea residue, grapefruit peel, onion slices, pineapple pieces and other indigenous methods can only play a role in covering up, such as covering up the odor of toilets. These things don't absorb formaldehyde in the air.
Besides these things, some people like to use perfume and air freshener, which is not desirable, because the chemical raw materials in perfume and air freshener may react with substances in the air, causing secondary pollution.
Purification method of chemical preparation
It mainly consumes formaldehyde in the air through physical adsorption or chemical reaction; There are two kinds of formaldehyde scavengers on the market at present. One is to purify the air by neutralizing formaldehyde and generating harmless substances. The other is to purify the air by blocking formaldehyde and preventing its volatilization. Advantages: high efficiency, immediate effect after use; Disadvantages: treating the symptoms but not the root cause; The release of formaldehyde is a very long process, which lasts for several years or even decades, and only a small part of formaldehyde is absorbed or reacted.
Latex paint absorption method
It is a new idea to absorb and decompose formaldehyde with latex paint. Through a unique formula, the emulsion with special molecular groups which can adsorb and decompose formaldehyde is selected to purify the home air.
Free formaldehyde in the air is consumed through chemical reaction, and water molecules that are harmless to human body and environment are generated. Disadvantages: Latex paint is passively absorbed and decomposed, and the release of formaldehyde is a very long process, which lasts for several years or even decades. Formaldehyde in furniture, carpets, paints, etc. Only a small part can be absorbed by the room.
Activated carbon adsorption
Solid activated carbon has the characteristics of many pores and has strong adsorption and decomposition effects on harmful substances such as formaldehyde. The smaller the activated carbon particles, the better the adsorption effect. The adsorption effect of activated carbon on formaldehyde is obvious. It should be noted that the amount of activated carbon is different according to the size of the space.
In addition, activated carbon needs to be replaced after it is adsorbed to a certain extent. Although the effect of activated carbon is good, it only passively absorbs toxic and harmful gases such as formaldehyde. Poor air circulation means decoration, and similar carbon packages and carbon sculptures on the market can only absorb the parts placed in the room.
Treatment method of air purifier
At present, air purifiers on the market are divided into negative ion type, ozone type, filtration and adsorption type, electrostatic integration type and photocatalyst type.
Different air purifiers have different working principles. For example, the negative ion type can purify the indoor air by generating negative ions and decomposing the odor and attached smoke in the air. For example, high-voltage electrostatic precipitation carbonizes bacteria and viruses, and high-concentration activated carbon circulates air through a fan, achieving very good results.
