This technology is fully applied on decoration pollution purification, daily air purification series of cars purification conservation campaign and environmental health electrical products, and the effect is significant.
Formaldehyde polymerization techniques
Contains three components which play the role of penetration, adsorption and scavenging.When brushed on the plate surface, it will rapidly penetrate into the interior of the plate, the active ingredient rapidly and formaldehyde lignin polymerization hair should produce a stable, non-toxic polymer material lignin glue a mesh structure.
Plasma catalytic purification technology
By low-temperature plasma module and VOC catalytic purification module used in combination, can efficiently purify the indoor formaldehyde, benzene and other harmful substances and other decoration pollution stench, VOC substances.
BTEX and TVOC rapid decomposition
Stranded in indoor air and attached to the furniture, wall surface formaldehyde, benzene and harmful gases and volatile organic compounds oxidation degradation, and the source of release of harmful substances like wallpaper glue can not penetrate oxidative degradation of the contact, broken down into carbon dioxide and water.
Photocatalyst catalytic decomposition technology

Photocatalyst technology is the use of nanoscale anatase titanium dioxide under sunlight (UV) irradiation to produce highly active genes, and it will remove  the oxidation of various pollutants in the air decomposition, which has a strong bactericidal , deodorant, anti-mildew, anti-fouling and self-cleaning, air purification function.
