Ultraviolet ray is a common name for ultraviolet ray. Long and short waves belong to radio waves, and radio waves and ultraviolet rays belong to electromagnetic waves. The electromagnetic waves generated by different reasons are arranged according to the wavelength from long to short: radio waves (…… very long wave, long wave, medium wave, short wave, microwave), infrared rays, visible light, ultraviolet rays, roentgen rays (X rays) and gamma rays.

The antiviral principle of ultraviolet rays is not to denature protein.

Principle of ultraviolet sterilization

Ultraviolet sterilization is to destroy and change the DNA (deoxyribonucleic acid) structure of microorganisms by ultraviolet irradiation, so that bacteria die immediately or cannot reproduce, thus achieving the purpose of sterilization. What really has bactericidal effect is UVC ultraviolet rays, because C-band ultraviolet rays are easily absorbed by DNA of organisms, especially the ultraviolet rays around 253.7nm are the best.

Ultraviolet sterilization is a purely physical disinfection method, which has the advantages of simplicity, broad spectrum, high efficiency, no secondary pollution, easy management and automation. With the introduction of various newly designed ultraviolet lamps, the application scope of ultraviolet sterilization is also expanding.

In addition, the sterilization principle of microwave is that thermal effect destroys protein and DNA, making them denatured.
