Scientific principle of ultraviolet disinfection

The scientific principle of ultraviolet disinfection
It mainly acts on the DNA of microorganisms, destroys the structure of DNA, and makes it lose the function of reproduction and self-replication to achieve the purpose of sterilization.
Features of UV lamp sterilization
1. After the lamp is turned on, the dirty indoor air is gradually cleaned due to the action of ozone and ultraviolet rays. Therefore, the lamp continuously supplies the source of fresh air. When the ozone is decomposed, the free bacteria in the air are also killed, which can prevent colds, colds and others. All kinds of air-borne infectious diseases prevent the infection of hepatitis and tuberculosis. UVC meter can be used to test the uvc intensity of the uvc light source.
2. Deodorant and mildew proof. Putting on this light in the bedroom and bathroom can not only prevent odor, but also kill flies, mosquitoes and other larvae. In a dark and humid room, it can prevent items from becoming moldy.
3. Pure physical sterilization without secondary pollution. Since the ultraviolet disinfection technology does not require any chemical agents, it will not cause secondary pollution to the surrounding environment.
4. Ultraviolet disinfection technology and disinfection efficiency are the highest among all disinfection methods.
5. It can effectively prevent SARS, H5N1, H1N1, encephalitis and other epidemic diseases with relatively strong spread.
