1. Ultraviolet light is produced by high ozone ultraviolet lamp. Infrared ray is produced by far infrared quartz tube.
2. Ultraviolet rays have the shortest wavelength and the strongest energy, but the penetrability is 0. So some bacteria on the surface of tableware can be removed. Infrared rays have a long wavelength. Good permeability, mainly used for heating.
3. The ultraviolet lamp can produce ozone at the same time as ultraviolet rays. It is also one of the main anti-virus means of disinfection cabinet. The main function of infrared ray is to heat the tableware in the disinfection cabinet and sterilize it at a high temperature above 120 degrees.
4, ultraviolet rays can be effectively sterilized because they need irradiation. So it has great limitations. Infrared rays are heated by wavelength. The sterilization effect is more thorough.
Extended data:
The far infrared high-temperature disinfection cabinet is mainly based on the physical principle, which uses the heat of far infrared rays to generate a high temperature of 120 degrees in a closed cabinet for disinfection. This disinfection method has the characteristics of high speed and strong penetration. Tableware and tea sets commonly used in daily life can be put into the cabinet for high-temperature disinfection.
The sterilization principle of ultraviolet disinfection cabinet is to irradiate microorganisms such as bacteria and viruses with ultraviolet rays, destroy the DNA structure in their bodies, kill bacteria or make them lose their reproductive ability. DNA has the strongest absorption of ultraviolet rays with the wavelength of 253.7nm, and the sterilization effect of ultraviolet rays is related to its irradiation intensity and total exposure, and the general killing rate can reach ≥ 99%.
