advantages of deep ultraviolet UV LED sterilization
|
 |
First the advantages of deep ultraviolet UV LED sterilization:
1. High-efficiency sterilization: the sterilization and inactivation of bacteria and germs is generally completed within a few seconds, almost instantaneously.
2. Broad-spectrum sterilization: It can kill almost all bacteria and viruses with high efficiency.
3. No secondary pollution: no other chemical pollutants are produced.
Second, UV band classification
Divide the ultraviolet band according to the wavelength:
UVA: 315-400nm (near ultraviolet NUV365-400nm), applications include curing, photocatalytic purification, anti-counterfeiting and other fields.
UVB: 280-315nm, applications include light health/medicine, plant growth light adjustment, etc.
UVC: 200-280nm (solar blind-"sun blind" ultraviolet light), used for sterilization and disinfection such as water and air.
Third, the principle of ultraviolet disinfection
Ultraviolet disinfection technology is based on the research foundation of modern epidemic prevention, medicine and photodynamics, using specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet lamps. Ultraviolet radiation damages microorganisms (bacteria, viruses, spores and other pathogens) and destroys the function of nucleic acid, thereby killing microorganisms and achieving the purpose of disinfection and sterilization. The inactivation effect depends on the dose of ultraviolet radiation.
