UVC LED teeb li cas (254/365nm) ua mob rau tib neeg lub cev thiab yuav tiv thaiv nws li cas?


Txhawm rau kom nkag siab txog kev puas tsuaj ntawm cov kab hluav taws xob ultraviolet rau tib neeg lub cev ntau dua qhov xav tau, cia kuv ua ntej qhia txog kev paub txog cov hluav taws xob ultraviolet (UV). Ultraviolet (UV) muaj peb tug kwv: UVA/UVB/UVC.

UV SERIES

Txhua pawg muaj tus cwj pwm txawv. Tsuas yog UVA thiab UVC tau ua ntawm no; 254nm belongs rau UVC band, thaum 365nm belongs rau UVA band. Ultraviolet lub teeb muaj luv luv wavelength tab sis siab zog. Kev puas tsuaj rau tib neeg lub cev txawv ntawm ob, yog li kuv yuav tham txog lawv cais.

The comparison chart of ultraviolet sterilization ability of different wavelength bands First, 254nm: 254nm is the band with the best sterilization effect, which belongs to the deep ultraviolet band, which is what we usually call UVC. This band is mainly used for sterilization. By destroying the genetic material such as DNA of bacteria and viruses, UVC changes the genetic transcription characteristics of cells, so that the organism loses the ability to synthesize and reproduce proteins, and can kill more than 99 percent of bacteria in a very short period of time. You need to be extra careful when you are in contact with this frequency band in daily operations, and the human body is very harmful. In the eye in particular, after UVC is absorbed by the cornea, the DNA of the corneal epithelial cells is damaged, the cells die, and the underlying nerve plexus is exposed. After the nerve is exposed, pain is transmitted directly to the brain until new corneal epithelial cells grow and re-cover the nerve plexus. However, although the UVC force value is very strong, it also has weaknesses. Its biggest disadvantage is its weak penetration ability, which can be blocked by ordinary plastic and glass. If you are accidentally exposed to ultraviolet rays in this band, it is best to go to the hospital and ask your doctor for advice. After talking about 254nm, let's talk about 365nm: 365nm is UVA, which belongs to shallow ultraviolet. UVA can directly pass through the clouds and reach the earth, so the sun we are in daily contact with contains a lot of UVA. This band is mainly used for curing in daily life, and the main application fields are printing, nail art, textile and so on. When we look at the teeth, this light uses UVA.


Piv nrog UVC, UVA kuj yog me me thiab tsis ua rau mob qhov muag. Tab sis nws kuj yog teeb meem rau tan, hnub wrinkled ntawm daim tawv nqaij, thiab ua kom cov kab mob cataracts thiab hnub nyoog - ntsig txog macular degeneration. Yog li ntawd, rau 365nm UV teeb, ua tshuaj pleev thaiv hnub, thiab tsis txhob ntsia ncaj qha rau hauv koj lub qhov muag!
