Vim li cas 310nm thiab 320nm, tsuas yog 10nm sib txawv, muaj cov teebmeem sib txawv?
Raws li kev faib tawm spectral, qhov sib txawv ntawm 310nm thiab 320nm ultraviolet lub teeb nyob hauv lawv.spectral assignment thiab qib zog, uas txiav txim siab qhov sib txawv tseem ceeb hauv qhov tob thiab cov txheej txheem ntawm lawv cov teebmeem ntawm daim tawv nqaij.
310nm ntog nyob rau hauv qhov nruab nrab - wave ultraviolet (UVB, 280-320nm).Cov ntaub ntawv qhia tias UVB raug xa mus rau "hluav taws xob hluav taws xob" vim nws lub zog siab dua, ua rau nws yog ib qho tseem ceeb hauv kev ua rau cov tawv nqaij puas. Nws cov teebmeem yog concentrated nyob rau hauv lub epidermal txheej, nrog thawj mechanisms xws li:
Inducing Epidermal Endoplasmic Reticulum Stress:UVB (xws li 310nm) tuaj yeem cuam tshuam endoplasmic reticulum homeostasis hauv hlwb, ua rau cov lus teb tsis muaj protein ntau. Kev ntxhov siab me ntsis koom nrog kev tswj hwm ntawm daim tawv nqaij, tab sis kev ua kom ntau dhau ua rau keratinocyte apoptosis thiab exacerbates inflammatory teb.
Ua rau Direct thiab Indirect DNA puas:UVB tuaj yeem ua rau DNA ncaj qha los tsim cov khoom lag luam xws li cyclobutane pyrimidine dimers. Tib lub sijhawm, los ntawm kev ua kom tawg ntawm cov pa oxygen reactive (ROS), nws ua rau oxidative DNA puas zoo li 8-hydroxydeoxyguanosine, ua rau muaj kev hloov pauv.
Ua rau Inflammatory Response:UVB induces keratinocytes los tsim ROS thiab pro-mob inflammatory yam xws li TNF- thiab IL-1, recruiting hlwb thiab ua rau daim tawv nqaij erythema thiab edema.

320nm belongs rau qhov pib band ntev -wave ultraviolet (UVA, 320-400nm).Cov ntaub ntawv qhia tau hais tias UVA nkag mus tob rau hauv dermis, thiab nws cov teebmeem kev lom neeg txawv ntawm UVB:
Deeper Level of Action:Nws feem ntau ua rau dermal collagen degradation thiab elastic fiber degeneration, ua tus tsav tsheb tseem ceeb ntawmdaim tawv nqaij photoaging(wrinkles, laxity) thiabpigmentation.
Qhov sib txawv hauv daim ntawv thov:Hauv kev lag luam, 320nm UVA yog lub teeb ci tseem ceeb rauphotocuring tshuab, siv rau tam sim kho coatings, inks, adhesives, thiab 3D luam ntawv resins. Nws lub zog raws nraim qhov nqus qhov siab ntawm feem ntau photoinitiators.
