Can novel coronavirus be killed by ultraviolet lamp?
Novel coronavirus has been panic buying. Many disinfectant products have been sold out. A series of respirators, disinfectants, alcohol and so on have been robbed.
UV lamp manufacturer:
There are three types of ultraviolet rays in sunlight, the wavelength of which is 100-275 nm, which can destroy the DNA of microorganisms (bacteria, viruses, fungi, chlamydia, etc.) and have bactericidal effect.
Medical ultraviolet lamp, also known as ultraviolet sterilization lamp (UV lamp), actually belongs to a kind of low-pressure mercury lamp. Like ordinary fluorescent lamp, it uses low-pressure mercury vapor;
There are mainly 254 nm and 185 nm lines of medical ultraviolet lamp. 254 nm ultraviolet light can kill bacteria by irradiating the DNA of microorganisms. 185 nm ultraviolet light can change the O2 in the air into O3 (ozone), which has bactericidal effect.
The novel coronavirus pneumonia diagnosis and treatment guidelines were released, and 75% alcohol, ether, chloroform, formaldehyde, chlorine disinfectant, peracetic acid and ultraviolet rays could inactivate the virus. Therefore, medical ultraviolet lamp is effective to kill virus.
In addition, if ultraviolet lamp is used for disinfection at home, family members must leave the disinfected room during disinfection to avoid damage caused by ultraviolet radiation on people (UV is a risk factor for all kinds of skin cancer). Pay attention to room ventilation after disinfection.
