UV Sterilization Machine
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.
The working principle of the equipment is that the ultraviolet sterilization band is mainly between 200-300nm, and the sterilization ability with the wavelength of 253.7nm is the strongest. When various bacterial viruses in water or air pass through the ultraviolet (253.7nm wavelength) irradiation area, ultraviolet rays penetrate the cell membrane and nucleus of microorganisms, destroying molecular bonds of nucleic acid (DNA or RNA), causing them to lose their replication ability or activity and die. To kill all bacterial viruses without using any chemicals. The germicidal lamp does not need to be converted into visible light. The wavelength of 100-200nm can play a good role in sterilization. This is because the cell has a regular absorption spectrum of light waves. Ultraviolet rays at 100-200nm have the largest absorption and are absorbed. The ultraviolet light actually acts on the cell's genetic material, that is, DNA, and it plays a photochemical role. The energy of ultraviolet photons is absorbed by the base pairs in the DNA, causing genetic material to mutate, causing the bacteria to die immediately or fail to reproduce. Purpose of sterilization.
Advantages of UV disinfection technology:
The disinfection effect of ultraviolet disinfection technology on bacterial viruses and other pathogens has been recognized worldwide, and it has unparalleled sterilization efficiency of other technologies. The germicidal effect of ultraviolet rays on bacteria and viruses is generally within one second. For traditional chlorine and ozone methods, it takes 20 to 50 minutes to achieve the sterilization effect of ultraviolet rays. It has a broad spectrum of efficient sterilization, no secondary pollution, safe and reasonable design, safe and reliable operation. Simple maintenance and low cost. This equipment occupies a small area and has no noise. Continuous mass sterilization. Wide application fields and many other advantages.
