Ultraviolet rays muaj ntau yam kev siv, uas tuaj yeem hais tau zoo rau peb lub neej. UV ultraviolet rays yog siv dav hauv txhua qhov chaw ntawm lub neej.
Lub npe hu ua UV ultraviolet rays xa mus rau lub hnub ci pom kev, uas tsis yog ntshav liab, uas yog qhov pom ntawm qhov muag liab qab. Ultraviolet yog lub ntsiab lus dav dav rau hluav taws xob hauv electromagnetic spectrum nrog wavelengths xws li 10 nanometers txog 400 nanometers.
Raws li qhov sib txawv wavelengths, ultraviolet rays feem ntau muab faib ua peb pawg: A, B, thiab C, raws li nram no: UVA yog 400-315 nanometers, UVB yog 315-280 nanometers, thiab UVC yog 280-100 nanometers. Raws li qhov sib txawv wavelengths, cov kev siv tshwj xeeb sib txawv.
Kev lag luam tseem ceeb ntawm UV A band yog kho, nrog tus sawv cev wavelengths ntawm 395 nanometers thiab 365 nanometers. UV curing daim ntaub ntawv muaj xws li UV nplaum curing nyob rau hauv cov zaub, hluav taws xob kho mob, instrumentation thiab lwm yam lag luam; cov khoom siv hauv tsev, rooj tog zaum, khoom siv hauv tsev, tsheb thiab lwm yam kev lag luam UV txheej kho; UV number case curing hauv luam ntawv, ntim thiab lwm yam lag luam;
UV curing ntawm cov khoom hauv microelectronics kev lag luam, thiab lwm yam. Ntawm lawv, UV LED hniav vaj huam sib luag kev lag luam tau dhau los ua qhov chaw kub. Qhov zoo tshaj plaws yog tias nws tuaj yeem tsim xoom-formaldehyde ib puag ncig tus phooj ywg vaj huam sib luag, nrog kev txuag hluav taws xob, cov khoom siv loj, khawb tsis kam, thiab cov txiaj ntsig zoo.
Ib qho tseem ceeb ntawm daim ntawv thov ntawm UV B band yog kev kho mob ntawm daim tawv nqaij kab mob, uas yog, daim ntawv thov ntawm ultraviolet lub teeb kho.
Cov kws tshawb fawb tau pom tias cov kab hluav taws xob ultraviolet nrog lub wavelength ntawm li 310 nanometers muaj qhov muaj zog ntawm qhov tsaus ntuj ntawm daim tawv nqaij, uas tuaj yeem ua kom cov tawv nqaij nrawm nrawm' s metabolism thiab nce cov tawv nqaij, uas tuaj yeem kho ntau yam. ntawm daim duab-vim kab mob ntawm daim tawv nqaij, xws li vitiligo.
UV B band kuj tuaj yeem siv rau hauv kev kho mob. Lub irradiation ntawm UVB band yog tam sim no siv los tswj kev ua haujlwm ntawm lub paj hlwb, txhim kho kev pw tsaug zog, thiab txo cov ntshav siab.
Tsis tas li ntawd, cov kev tshawb fawb tau pom tias UV B band tuaj yeem ua kom muaj cov polyphenols hauv qee cov nplooj zaub. Cov polyphenols tau lees tias muaj kev tiv thaiv kab mob qog noj ntshav, tiv thaiv kab mob qog noj ntshav, thiab tiv thaiv kab mob qog noj ntshav.
Vim nws luv wavelength thiab siab zog, UV C-band ultraviolet rays tuaj yeem rhuav tshem cov qauv molecular ntawm cov kab mob microbial (xws li cov kab mob thiab cov kab mob) nyob rau lub sijhawm luv luv. Cells tsis tuaj yeem rov tsim dua tshiab, thiab cov kab mob thiab cov kab mob tsis muaj peev xwm rov ua dua lawv tus kheej. Yog li ntawd, UVC-band khoom tuaj yeem siv dav. Siv dej, cua, thiab lwm yam rau kom tsis muaj menyuam thiab tua kab mob. Xws li cov khoom siv tshuaj tua kab mob, microwave ncu.
UV LED yog ib qho ntawm cov khoom tseem ceeb ntawm GMKJ LED. Yog tias koj xav tau, thov hu rau peb: Nickole@szgmled.com.
