In daily life, UV is used widely.The UV has different functions and uses.
First,UV has a health care effect.Using UV radiation can improve sleep and lower blood pressure.Receiving UV radiation can enhance immune function and strengthen the phagocytic ability of white blood cells.
Second,UV has a sterilizing effect. Short-wave UV is extremely destructive to microorganisms. When the bacterial body is irradiated by short-wavelength UV, the nuclear protein and DNA of the cell absorb the energy of the wavelength band strongly.It can break the chain between them, then kill the bacteria.
Third,UV can decompose organic matter. The surface of building materials, furniture and electrical appliances contains a small amount of nano-sized titanium dioxide powder, and will adsorb volatile harmful substances VOC, such as formaldehyde, benzene, toluene, ethanol, chloroform, etc. These harmful substances can be decomposed after being exposed to UV.
At last,UV is used for oil fume oxidation.The oil can change its molecular chain after being irradiated by UV.
At the same time, the UV lamp reacts with oxygen in the air to produce ozone, which cools the oil molecules to produce carbon dioxide and water. The organic matter in the oil fume is photodegraded and oxidized, and the peculiar smell is also eliminated.
