Guangmai Technology is professional in making the 12V 24V Aluminum UVC LED PCBA Boards 270nm for Germicidal.
Ultraviolet rays are generally divided into three categories according to wavelength: long-wave ultraviolet rays with a wavelength of 315nm-380nm are referred to as UVA, medium-wave ultraviolet rays with a wavelength of 280nm-315nm are referred to as UVB, and short-wave ultraviolet rays with a wavelength of 200nm-280nm are referred to as UVC. At present, most of the ultraviolet disinfection lamps on the market use UVC ultraviolet rays to achieve disinfection and sterilization. Ultraviolet rays can kill various microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, rickettsiae and mycoplasma, etc., with a broad spectrum.
The sterilization mechanism of ultraviolet light
1. Destroy genetic material
The reproduction and survival of bacteria and viruses are based on DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). UVC ultraviolet rays can destroy the nucleic acid structure and function of cells or viruses. The absorption spectrum of nucleic acid is almost completely consistent with the spectrum of bactericidal effect of ultraviolet light. Nucleic acid is a polynucleotide chain connected by phosphodiester according to the principle of base pairing of purine and pyrimidine. It has a strong absorption effect on ultraviolet, and has a strong absorption at 250~270nm. The maximum absorption can be seen. When the strong bactericidal 253.7nm ultraviolet rays irradiate microorganisms, the absorbed ultraviolet rays act on nucleic acids, and the energy of ultraviolet photons is absorbed by base pairs in DNA, destroying one or several chemical bonds in nucleic acid molecules. , Causing the decomposition and denaturation of nucleoprotein or nucleic acid, causing protein and enzyme synthesis obstacles in bacteria, causing death or inability to reproduce offspring, achieving the purpose of sterilization.
2. Affect enzyme activity
Ultraviolet rays can also affect the activity of many enzymes in bacteria and viruses, change the structure and function of their protein molecules, affect the synthesis of proteins and nucleic acids, and reduce the toxicity or even death of bacteria or viruses.
3. Destroy protein
185nm ultraviolet radiation ionizes O2 in the air, generating oxygen free radicals and ozone, both of which have a strong oxidizing effect, denaturing proteins, losing the ability of bacteria to metabolize, and causing bacteria to die.
