In 2020, the new coronavirus will spread globally in a raging manner. Whether you can take off your mask and breathe safely has become a new social topic.In addition to air pollution, haze, formaldehyde, PM2.5, etc, bacteria and viruses in the air have become an air quality issue that we are more concerned about.
The current sterilization and disinfection lamps in the lighting market mainly use UVC ultraviolet sterilization methods, which have certain disadvantages in use, and have great damage to the human skin. They can only be used without people, which leads to many places not suitable for installation.
Distar's air purification lamp adopt the latest titanium dioxide photocatalyst + UVA technology. It will not cause any harm to the human body during high-efficiency sterilization and disinfection, and it is suitable for installation in any place.
The principle of titanium dioxide photocatalyst:
Advantages of titanium dioxide photocatalyst:
1. Environmental protection and non-toxic
TiO2 photocatalyst has high chemical stability and is recognized as a safe substance by the US Food and Drug Administration (FDA). It has no harm to the human body. It is widely used in food, daily necessities, cosmetics, medicine, and aquaculture. ,
2. Disinfection and sterilization
After the photocatalyst absorbs natural light, it has a strong ability to absorb electrons, that is, strong oxidizing. It can effectively catalyze the decomposition of harmful organic and inorganic substances, and can also eliminate bacteria and viruses. For example, photocatalysts can degrade indoor harmful volatile organic compounds such as formaldehyde, dichlorobenzene, toluene, xylene, TVOC, etc. into non-toxic and harmless small molecules of water and CO2. At the same time, it can also decompose and harmlessly treat the toxins released by bacteria and fungi.
3. Permanent
The photocatalyst stock solution has the characteristics of quick-drying. After being coated on the surface of the substrate, it can dry quickly and become a water-insoluble substance. Under the irradiation of light, it can continuously purify pollutants, and has the advantages of long-lasting and continuous action.
4. Super hydrophilic
Under normal circumstances, the photocatalyst coating surface has a large contact angle with water, but after being irradiated with ultraviolet light, the contact angle with water is reduced to less than 5°, and can even reach 0°, that is, the water droplets completely infiltrate the surface of the photocatalyst. Very strong super hydrophilic.
5. Self-purification
The surface processed by the photocatalyst is excited by ultraviolet radiation, which can decompose the organic matter in contact, which not only has a sterilization effect, but also decomposes harmful substances into harmless small molecules. At the same time, due to the super-hydrophilic properties exhibited under light conditions, when dust falls on the photocatalyst coating, it can be cleaned with clean water only to achieve the purpose of cleaning the surface.
