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.

Pay attention to protection:
Ultraviolet rays have a powerful lethality to bacteria, and they also have a certain degree of damage to the human body. The most vulnerable part of the human body is the cornea of the eyes. Therefore, you must not look directly at the lit lamp tube at any time to avoid injury When it is necessary to watch, use ordinary glass (wearing glasses) or transparent plastic sheet as a protective face shield. Do not use quartz glass by mistake, because ordinary glass is almost completely impermeable to ultraviolet rays. Once injured, don't panic and burn your face. After a few days, the epidermis comes off and heals without treatment. Eye injuries can be red, swollen, tearful, and tingling, and it will take about three or four days to heal. However, in the event of injury, it is still recommended to seek medical treatment immediately.
Maintenance and maintenance of UV sterilizer:
1 Regular inspection to ensure the normal operation of the UV lamp.
2. After continuous use for 8000 hours or one year, the UV lamp should be replaced. When replacing a new lamp, first unplug the lamp power socket and take out the ultraviolet lamp. Be careful not to touch the quartz glass of the new lamp with your fingers, as the stain will affect the intensity of the light. At the same time, carefully put the lamp into the interior of the sterilizer.
