For this reason, human beings use masks to prevent the spread of the virus, and use ultraviolet UV LED for sterilization to prevent the spread of the virus.
UV glue curing generally uses 365nm LED wavelength, and UV ink, and UV paint generally use 395nm led wavelength. Through special design, UV LED can emit a complete continuous ultraviolet light band, which can meet the requirements of edge sealing, bonding, printing and curing.
1. UVA: The wavelength is 320-395nm, also known as long-wave black spot effect ultraviolet rays. It has strong penetrating power and can penetrate most transparent glass and plastics. More than 98% of the long-wave ultraviolet contained in sunlight can penetrate the ozone layer and clouds to reach the surface of the earth.
2, UVB wavelength is 280-320nm, also known as medium wave erythema effect ultraviolet. Medium penetration, its shorter wavelength part will be absorbed by the transparent glass, most of the medium-wave ultraviolet contained in sunlight is absorbed by the ozone layer, and only less than 2% can reach the surface of the earth, which is particularly strong in summer and afternoon.
3, UVC wavelength is below 280nm, also known as short-wave sterilization ultraviolet. Its penetrating ability is weak, unable to penetrate most of transparent glass and plastic. The short-wave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer. Short-wave ultraviolet rays are very harmful to the human body. Short-term exposure can burn the skin, and long-term or high-intensity exposure can also cause skin cancer. UV high-pressure mercury lamps and ultraviolet germicidal lamps emit UVC short-wave ultraviolet rays.
