Information

Ultraviolet disinfection is an old story. Human beings have long been using ultraviolet part of sunlight sterilization tradition, domestic and foreign scientific and technological workers have more than 200 years of history of ultraviolet research. The ultraviolet radiation commonly used for disinfection is uv-c, which has a wavelength range of 200 nm to 280nm. According to a report in the Journal of Lighting Engineering, ultraviolet sterilization lamp is a special light source product, which emits ultraviolet (UV) radiation in the wavelength range of 100 -- 400 nm. The ultraviolet radiation in the band of 100 -- 280 nm used for sterilization is called UV-C. The 240-280 m band of UV-C is the most effective sterilizing band. Usually, the ultraviolet sterilization lamp mainly refers to the ultraviolet lamp whose wavelength is 253.7 nm.
"The virus is sensitive to ultraviolet light and heat," according to the NHC's Diagnosis and Treatment Protocol for COVID-19. Scientific studies have shown that ultraviolet light can kill pathogens, such as influenza and superbugs. Ultraviolet LED lighting technology will effectively assist in the elimination of viral pathogens, providing a degree of protection to patients, customers, staff and families, and preventing the spread of infection.
On April 9, 2020, the national standard GB28235-2020 uv disinfector sanitary requirements instead of GB28235-2011 ultraviolet air disinfector safety and health regulations, promulgated and put into practice the announcement in November 2020, uv disinfector using light source must be specified with sterilization factor of 200 to 280 nanometers (nm) UVC band, clear classification of air disinfector, water sterilizer, content table sterilizer, such as technical requirement specification, technical content and all the changes are "mandatory".
