Air purification methods are:
One, photocatalytic technology
Japanese scientists were the first to discover the light TiO?single crystal electrode can decompose water, photocatalytic technology put into use in the 1990s. When air and water pass through the photocatalytic material is the technology unit, a large number of hydroxide ions are produced through redox reaction.
These ions diffuse in the air, through the destruction of bacterial cell membranes, coagulation of viral proteins sterilization and disinfection, decomposition of a variety of organic compounds and some inorganic substances, get rid of harmful gases and odors. The photocatalytic sterilization mechanism has been experimentally proved to be: cell permeation, destruction of coenzyme A, degradation of endotoxin, denaturation of proteins and lipids decomposition and cell mineralization.
Two, quantitative activated oxygen technology
Activated oxygen is a mature technology, the world has been using activated oxygen for more than a hundred years, it can quickly and thoroughly inactivate the bacteria, reasonable use of the most environmentally friendly, one of the most thorough and effective way of purification is internationally recognized. At the same time, its strong oxidizing properties enable it to react with carbonyl (carbon-oxygen) and hydrocarbon-based (carbon-hydrogen) compounds such as formaldehyde and benzene.
Three, negative ion technology
Negative ion technology, also known as unipolar ion flow technology, the negative ion flow generated by the adsorption of positively charged suspended particles in the air, so that the particles continue to accumulate and become heavier, so that it is out of the aerosol state and precipitation.
Negative ions for the diameter between 0.001-100 microns of particles have a sedimentation effect but for particles less than or equal to 2.5 microns of particles known as fine particulate matter, i.e., PM2.5, only high activity of small particle size anion has a significant effect. Negative ion air purifier using the characteristics of air diffusion so that the whole room is full of negative ions, can quickly remove dust and dust, leaving no dead ends, purification effect is more thorough.
Four, activated carbon
Activated carbon with wood chips, shells, lignite and other carbon-containing substances as raw materials, made of carbonization and activation. There are two kinds of powder (particle size of 10-50 microns) and granular (particle size of 0.4-2.4 mm). The general character is porous, large specific surface area.
Total surface area of 500 to 1000 square meters per gram, the purifying effect of activated carbon and pore size is directly related to the pore size when the pore size is close to the diameter of the particulate matter when the purifying effect is the most obvious, Coconut Vitamin Carbon is a new type of activated carbon, the pore size of which is smaller than the diameter of the purifying effect is more obvious.
Fifth, the ecological negative ion generation chip technology
Eco-negative ion chip will be piezoelectric ceramic negative ion generator and ion converter (Ion converter) highly integrated, not only to achieve the generation of ecological level of negative ions, but also greatly reduce the volume and thickness of the negative ion products, the world's most leading ecological negative ion generation technology.
The Ion Converter is an upgraded version of the Negative Ion Converter, which is essentially a pulse frequency enhancer applied to the Negative Ion Generation System. Pulse frequency enhancer can effectively increase the pulsation energy of negative ions, so that the use of this technology of negative air ion function appliances to produce the equivalent of nature's small particle size, high activity of the ecological level of negative oxygen ions.
