2. The volatilization period of formaldehyde is about 5- 15 years, and the volatilization process is relatively long. Pay more attention to window ventilation, which is beneficial to the volatilization and dilution of formaldehyde. You can raise some fish, because formaldehyde is a water-soluble substance, which can reduce the formaldehyde content in the air. Raising some green broad-leaved plants will help to absorb and alleviate the concentration of formaldehyde.
3, you can put some activated carbon in the appropriate position, you can absorb some formaldehyde substances, but the effect is slow. When using formaldehyde scavenger, you must choose an air purifier that will not produce secondary pollution. If the effect of sleep sensation is good, it can quickly remove the odor in in addition to formaldehyde.
Extended data
Plant absorption
Plants have a strong ability to absorb formaldehyde, such as cactus, chlorophytum, aloe, clivia, cycad, chrysanthemum and so on.
Comments: Many plants do have certain air purification effects. 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.
Ventilation and exhaust
Air exchange is ventilation. The higher the indoor and outdoor air exchange rate, the better the effect of reducing indoor pollutants. Strengthening ventilation, diluting indoor air pollutants with outdoor fresh air, reducing the concentration of toxic and harmful gases and improving indoor air quality are the simplest methods to prevent and control domestic decoration pollution.
purification treatment
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.
Comments: The air purifier has a certain effect on absorbing formaldehyde, but it is generally effective only when it is used in a confined space. If you use the air purifier with the window open, it will not only have no effect but also waste electricity.
chemical agent
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.
Comments: The effect is obvious, but it will rebound soon. The preparation for neutralizing formaldehyde can only neutralize some free formaldehyde in the air. Imagine how the board is so thick that formaldehyde can be removed from it. The blocking method only temporarily blocks formaldehyde to prevent its release, but formaldehyde has always existed in furniture and will be released slowly one day.
