The wavelength of ultraviolet ray is larger than that of medium ultraviolet ray, which is called far ultraviolet ray , In accordance with the CIE The definition of 、UV-C The wavelength range is 100-280nm.C Band ultraviolet lamp is commonly known as ultraviolet germicidal lamp .UVC Sterilization lamp is a kind of low-pressure mercury lamp , It uses a lower vapor pressure of mercury ( <10-2 Pa) Be stimulated to emit ultraviolet light , There are two main luminescence lines : One is 253.7nm wavelength ; The other is 185nm wavelength , Both are invisible to the naked eye C Band ultraviolet .
 Ultraviolet germicidal lamp
Ultraviolet disinfection technology has incomparable sterilization efficiency compared with other technologies , The sterilization efficiency can reach 99%-99.9%. And traditional chlorine 、 Ozone and other chemical disinfection methods generally need to 20 Minutes to 1 Hours .
UVC The germicidal lamp does not need to be converted to visible light ,253.7nm The wavelength of can play a very good role in sterilization , This is because there is a rule in the absorption spectrum of light waves by cells , stay 250-270nm Has the greatest absorption of ultraviolet rays , The absorbed ultraviolet rays actually act on the genetic material of the cell, i.e DNA, It plays a photochemical role , The energy of ultraviolet photons is DNA Base pair absorption in , Cause genetic material to mutate , Cause bacteria to die instantly or fail to reproduce , To achieve the purpose of sterilization .
Ultraviolet germicidal lamp is generally used to sterilize the air 、 Object surface 、 Water to disinfect .253.7nm Wavelength can effectively kill bacteria and viruses , Predecessors have already done a lot of research , There is no doubt about it . Ultraviolet sterilization is characterized by broad spectrum , There are some viruses that are difficult to destroy in high temperature , It can be quickly destroyed by ultraviolet light , This is because the sterilization mechanism of ultraviolet ray is different from other methods .
Sterilization : Water molecules in the air and photocatalyst treated surfaces , Catalyzed by ultraviolet light , Produce oxidation , Break down bacteria in the air .
Deodorization : The main daily odor source is ammonia , hydrogen sulfide , Methyl mercaptan , Acetaldehyde, etc , Photocatalyst is better than ozone , Negative ions are more oxidizing , These odor sources can be generated in the presence of photocatalysts , Use fluorescent lamp to produce photocatalyst oxidation to decompose odor source .
Remove the smell : It can generate a large amount of ultraviolet light speed to irradiate the odor gas , Degrade and convert the odor gas , Become a low molecular compound 【UV+O₂→O﹣+O*( Reactive oxygen species )O+O₂→O₃( ozone )】, Become, for example CO₂、H₂O And other harmless gases , Achieve the effect of effectively removing odor , And will not produce secondary pollution .
