There are two main emission lines of UV sterilization lamp: 254 nm and 185 nm. Among them, 254nm is ultraviolet without ozone, and 185nm is ultraviolet with ozone.
Advantages: ozone has strong oxidation effect, which can effectively kill bacteria. The dispersion of ozone can make up for the shortcomings of ultraviolet ray spreading only in a straight line and disinfection with dead angle.
Disadvantages: but excessive ozone is an invisible killer! It strongly stimulates people's respiratory tract, causing sore throat, chest tightness, cough, bronchitis and emphysema. After detoxification, windows need to be opened for ventilation.
Advantages: no ozone, people can enter the room immediately after sterilization.
Disadvantages: only spread along the straight line, disinfection has dead angle.
UV irradiation should be limited in time, and the intensity of UV radiation should be sufficient. Generally, 30-60 minutes is the best time to irradiate Zhi. The ultraviolet light of the ultraviolet disinfection lamp Dao will have a certain impact on the human body, and can not directly irradiate the human body.
