What is deep UV?

Ultraviolet is the general term of electromagnetic wave with the wavelength of 100-400nm emitted by the sun, which is invisible to human eyes. According to the wavelength of ultraviolet rays, ultraviolet rays are usually divided into three categories: A, B and C, namely near ultraviolet (UVA), far ultraviolet (UVB) and ultra short ultraviolet (UVC). UVC has the largest energy and is extremely destructive to microorganisms. However, when it passes through the stratosphere of the earth's surface, it is basically absorbed by the ozone layer and can not reach the earth's surface. Therefore, an artificial "Sunlight" - led deep ultraviolet rays should be used He was born out of love.

Deep ultraviolet -- artificial light for sterilization

This "artificial light" for sterilization, selected a specific band (260-280nm) of deep ultraviolet light, can penetrate the biological cell membrane and nucleus, destroy the molecular structure of DNA and RNA, kill all kinds of bacteria in a short time, such as bacterial propagules, spores, viruses, fungi, etc., the killing rate is as high as 99.9%. Among them, 275nm UVC is a medical band for disinfection, and it is also a recognized technology for disinfection in the international medical industry.

Advantages of deep UV sterilization

Broad spectrum sterilization: ultraviolet sterilization has the highest broad-spectrum. It can effectively kill almost all microorganisms, including bacteria, tuberculosis, viruses, spores and fungi.

High efficiency: UV disinfection fast, good effect. Under a certain radiation intensity, the general pathogenic microorganisms can be killed in only ten seconds, and some bacteria that cannot be killed by chlorine disinfection can also be killed.

Environmental protection: UV sterilization does not need to add any chemicals. It directly kills bacteria or destroys their reproductive capacity through short wave radiation, without pollution and residue, and does not cause secondary pollution to the surrounding environment.
