In the cosmetics industry, when using LED UV curing ultraviolet lamps to cure ABS material signage with UV ink, can the lamp be used for disinfection?
Case 2022-06-14
In the cosmetics industry, LED UV curing ultraviolet lamps used for curing ABS material signage with UV ink are usually not suitable for disinfection.The wavelengths emitted by LED UV curing ultraviolet lamps are mainly 365nm, 385nm, 395nm, 405nm, etc. 47. The ultraviolet rays with sterilization and disinfection effects are mainly in the UVC band, with a wavelength range of 200-280nm. Among them, ultraviolet rays around 253.7nm have the best sterilization effect. 23. The wavelength of LED UV curing ultraviolet lamps is not in the UVC band with good sterilization effect, and its power is mainly used to meet the ink curing needs. It is not designed according to the irradiation intensity and dose required for disinfection. It is difficult to effectively destroy the DNA or RNA structure of bacteria and viruses and is difficult to achieve the disinfection purpose.
