How does the ultraviolet sterilizer sterilize medical masks?


Ultraviolet sterilizer is commonly used in the food processing industry to provide rapid sterilization of a wide variety of packaged food and dairy products. Now, under the severe situation of the global epidemic, we have gradually developed a new application of ultraviolet sterilizer — effective sterilization of medical instruments and surgical masks. So, how effective is the ultraviolet sterilizer on the sterilization of medical masks? How do we use a UV sterilizer to disinfect masks?

The main advantages of UV sterilizer

Ultraviolet disinfection technology to bacteria, viruses and other pathogens disinfection effect has been recognized in the world, with other sterilization technology can not match the sterilization efficiency. The bactericidal effect of ultraviolet light on bacteria and viruses is generally achieved within one second.

Traditional chlorine sterilization and ozone sterilization, to achieve ultraviolet sterilization effect generally takes 20 ~ 50 minutes, with high efficiency, broad spectrum, no secondary pollution, safe and reasonable design, safe and reliable operation, etc.

Why use a UV sterilizer to disinfect surgical masks?

Since the outbreak of COVID-19, the resources of masks in countries around the world have suddenly become very scarce. As a result, mask factories in many countries began to mass-produce masks. In the process of mask processing, attention should be paid to cleaning and disinfection of masks to ensure the quality of masks. Uv sterilizer is favored by the market because of its fast sterilization speed and good sterilization effect.

Working principle:

The ultraviolet bactericidal band is mainly between 200 and 300nm, and the wavelength of 253.7nm has the strongest bactericidal ability. When water or air in various bacteria and viruses through the marker (253.7 nm wavelength) exposure to the sun’s ultraviolet rays, ultraviolet radiation will penetrate the cell membrane and nucleus of microorganism, undermine its nucleic acid (DNA or RNA) molecular bonds, make its losing the ability to replicate or activity and death, and in the case of without using any chemicals to kill all bacteria and viruses.

Ultraviolet sterilization equipment has no dead Angle, complete sterilization, low energy consumption, flexible installation and so on. Machine body material is stainless steel, there is no metal ion infection problem. Product structure is quartz sleeve type, with closed container, equipped with electric control device. Among them, the theoretical life of key ultraviolet lamp management reaches 10,000 hours, reaching the international advanced level.
