Method of indoor formaldehyde removal
1. Physical adsorption technology to remove formaldehyde
It is mainly a variety of air purifier, China has some manufacturers to produce purifier products, but most manufacturers are still producing mechanical filtration, ozone and air negative ion generator. Such products mainly adsorb suspended solids in the air, and also have certain adsorption effect on indoor formaldehyde and other pollutants.
(1) air purifier has certain adsorption effect on indoor formaldehyde and other pollutants.
(2) Mayan blue material: it has numerous tiny pores and weak electricity. It can absorb and lock harmful molecules such as formaldehyde and toluene, and decompose it into harmless gas. It is a fine material for removing formaldehyde.
(3) the harmful gas absorber, furniture can treasure: the adsorption of indoor formaldehyde and other harmful gases catalytic decomposition.
(4) in addition to flavoring agents and formaldehyde capture agents, the free formaldehyde in wood-based panels can be effectively reduced when used in decoration works. The commonly used method is to spray formaldehyde scavengers or formaldehyde traps in indoor air, or to use some preparations that can instantly eliminate odor. These methods only have a scavenging effect on free formaldehyde and can not be effective for formaldehyde released from basic artificial boards. There is also a kind of formaldehyde removal method is to use the closed principle, directly used on the surface of furniture, with this formaldehyde scavenger, will have transparent or bright white film on the furniture surface. Although the sealing method has immediate effect, but the long time closed also has loopholes, and can not fundamentally remove formaldehyde.
(5) formaldehyde sealant: Furniture wall without brushing on the paint processing and wood-based panel, reduce formaldehyde emission.

2, catalytic technology for removing formaldehyde
Catalysis technology is also known as the cold catalyst technology, with multi phase catalysis and ultrafiltration, thus ensuring that many harmful flavors are decomposed into harmless and tasteless substances at normal temperature and atmospheric pressure, and it is changed from simple physical adsorption to chemical adsorption and side adsorption side decomposition, so as to improve the type and adsorption effect of contaminated particles. The rate and saturation capacity do not produce two times of pollution, and the life of the adsorbed material is more than 20 times more than that of the ordinary material. It is more pertinent and can catalyze the catalytic decomposition of indoor formaldehyde and other harmful gases.

3. Chemical neutralization technology for formaldehyde removal
At present, some experts have developed a variety of deodorants and formaldehyde catcher. These products generally use complex technology to destroy the molecular structure of harmful gases such as formaldehyde and benzene, neutralize the harmful gases in the air, and gradually remove the harmful gases, and finally achieve the purpose of improving the indoor air quality. But we should pay attention to the opportunity to use, preferably combined with decoration works, can effectively reduce the free formaldehyde in wood-based panels.
4, plant formaldehyde removal
(1) Chlorophytum
Characteristics: easy to breed, strong adaptability, one of the most traditional hanging plants. Its leaves are slender and soft, and they produce small plants from their axils. They are hung down from the bottom of the basin, spreading and drooping, like flowers. They are evergreen all the year round.
Efficacy: it absorbs more than 80% of indoor harmful gas and absorbs formaldehyde. In general rooms, l to 2 pots and Chlorophytum can be absorbed, and toxic gases in the air can be absorbed. Therefore, Chlorophytum is also known as the "green purifier".
