Ultraviolet radiation is a kind of low-energy electromagnetic wave, which is widely used in medical treatment, health and epidemic prevention, food industry, pharmaceutical industry and so on. But how to use the ultraviolet lamp correctly, in order to ensure its sterilization effect, extend the lamp’s service life, to avoid accidental injury, is to ask each operator to master first, now talk about the use of experience in recent years. 

1 The ultraviolet disinfection principle uses the ultraviolet radiation, causes the mycelium protein to have the photolysis, the denaturation, the mycelium amino acid, the nucleic acid, the enzyme are destroyed to die. At the same time, when ultraviolet rays pass through the air, the oxygen in the air is ionized to produce ozone, and the bactericidal effect is strengthened. 

2 ultraviolet disinfection method ultraviolet radiation is mainly used for air and surface disinfection of objects, Wavelength 2573A. For Air Disinfection, the effective distance does not exceed Zm, the irradiation time is 30 ~ 60Min, the effective distance is 25 ~ 60cm, the irradiation time is 20 ~ 30min, it takes some time to warm up the lamp from 5 to 7 minutes to ionize the oxygen in the air to produce ozone.
