Found and application of photocatalytic began in 1972, after more than 40 years of unremitting efforts, the application of nanometer photocatalytic technology research has made breakthrough progress.
Through the environment science and technology research, found that nano light catalyst has the following advantages: safety -
Under the condition of normal temperature can response, small energy consumption, end product is harmless inorganic small molecules, such as carbon dioxide and water is harmless to the human body;
Photocatalytic decomposition of various harmful organisms in the air, to solve the secondary pollution problems of the traditional air purification method;
Smooth accelerant while on the decomposition of harmful substances in the air speed is not the same, but will eventually destroy it all;
Because titanium dioxide is very stable, catalytic role only, does not damage, so in theory the light catalyst can always play a role.
Photocatalytic sterilization principle of nano light catalyst has a strong photocatalytic bactericidal action.
Based on nanometer TiO2 photocatalysis kill death curve, gram positive bacteria Yin, conventional culture compare and transmission electron microscope concluded that nano TiO2 photocatalytic sterilization, starting from the bacterial cell walls, its produce free radicals that can destroy cell wall structure, make the cell wall rupture, breakage, disintegration of plasma membrane, and then enter the cell body internal lining damage and cell components, cytoplasm condensed, causing cell content overflow, can appear bacteria cavitation phenomenon.
Thus confirmed that the antibacterial mechanism of nanometer TiO2 is under the photocatalysis, nanometer TiO2 ban on electron from valence band transition to the conduction band, formed in the surface of highly active electronic -
Hole pair, and further form OH ˉ, O2 ˉ, OOH ˉ through a series of physical and chemical actions destroy bacterial cells, thus to kill bacteria, achieve sterilization effect.
Because it is extremely strong reduction function, can be air formaldehyde, benzene, toluene, ammonia, TVOC and other harmful down into harmless CO2 and H2O.
Itself does not change in the process of reaction and loss, under the irradiation of light can be continuous decomposition of pollutants.
As a famous domestic brand of medical air sterilization machine, conduct the thorough research to the environment through the nano light catalyst, success will be its advantages of application on air sterilizer
equipment, the hospitals, homes, offices and other places of air purification play an important role, more rapid decomposition of indoor formaldehyde, benzene, ammonia, TVOC and other harmful substances of indicators have reached the international advanced level, is a breath of fresh for the consumer provides strong harmful substances, indoor air to respiratory health line of defense.
