Microwave electrodeless ultraviolet sterilization equipment : The ultraviolet ray used for disinfection is C-wave ultraviolet ray, whose wavelength scale is 200nm~275nm, and the wave band with strong bactericidal effect is 250nm~270nm. It is necessary for the ultraviolet light source used for disinfection to produce a bactericidal ultraviolet lamp with the irradiation value reaching the national standard to prepare the ultraviolet disinfection lamp.     

The quartz glass tube of grade shall be selected to obtain the ultraviolet radiation intensity that meets the requirements. The ultraviolet disinfection lamp can be equipped with a reflector made of data with high ultraviolet reflection coefficient (such as polished aluminum plate). The ultraviolet lamp used for disinfection is required to radiate 253.7nm ultraviolet intensity when the voltage is 220V, the ambient relative humidity is 60%, and the temperature is 20 ℃.    

(Strength in service) shall not be less than 70 μ W/cm2 (ordinary 30W straight tube ultraviolet lamp is measured at a distance of 1 m from the lamp tube, especially the ultraviolet lamp is measured at the application interval, and the applied ultraviolet intensity meter is necessary to pass the calibration and is within the validity period; the applied ultraviolet intensity monitoring indicator card should obtain the approval of hygiene and be used within the validity period). The radiation intensity of the ultraviolet lamp gradually decreases during the application process, Therefore, the intensity of disinfection ultraviolet should be measured regularly.
