365nm thiab 395nm yog ob qho tib si UVA wavelengths(315-400nm ntau), feem ntau siv hauv "blacklight" daim ntawv thov xws li fluorescence, kho, thiab tshuaj xyuas. Qhov sib txawv ~ 30nm ua rau pom qhov sib txawv ntawm qhov ua tau zoo, kev ua tau zoo, thiab siv rooj plaub.
1. Qhov txawv ntawm lub cev tseem ceeb
Wavelength & Zog- 365nm luv dua thiab muajsiab zog photon("qhov tob" rau hauv UV). 395nm ntev dua, qis zog, thiab ze rau qhov pom spectrum (violet pib nyob ib ncig ntawm 400nm).
Pom Lub Teeb Pom Kev:
365nm ua: Emits feem ntau pom tsis pom UV nrog qhov pom tsawg tsawg "kua dej." Tshwm li ib tug dull xiav -dawb los yog faint glow rau ntawm qhov muag liab qab.
395nm ua: Production apronounced ntshav/violet pom glowvim nws txoj kev nkhaus spectral spills ntau rau pom lub teeb.
Brightness & Efficiency- 395nm LEDs feem ntau ci dua / pheej yig dua nrog ntau dua radiant flux. 365nm yog ntau "ntshiab" UV tab sis feem ntau kim dua thiab tej zaum yuav hnov zoo dua vim qhov pom tsis tshua pom.
2. Fluorescence (Glow) cuam tshuam
365nm uafeem ntau yogsuperiorrau muaj zog, muaj tseeb fluorescence. Nws ua kom cov ntaub ntawv muaj txiaj ntsig zoo (xws li, kev ruaj ntseg nta ntawm daim ntawv nyiaj, cov zis tso zis, cov zaub mov, cov kua dej hauv lub cev, qee yam resins, thiab kev ruaj ntseg inks). Nws nthuav tawm cov ntsiab lus zoo dua nrog kev cuam tshuam tsawg dua los ntawm pom lub teeb liab.
395nm uaua haujlwm rau cov teebmeem ntawm lub teeb dub tab sis ua rau tsis muaj zog lossis tsis muaj zog fluorescence ntau zaus. Lub paj liab qab tuaj yeem ntxuav tawm cov ntsiab lus tsis meej.
Piv txwv: Ntawm Teb Chaws Asmeskas txiaj, 365nm qhia meej txog UV-reactive holograms thiab strips uas 395nm yuav plam lossis qhia tsis zoo.
3. Curing Applications (Resins, Glues, Inks, Coatings)
365nm ua: Feem ntau zoo raunto curing, ntshiab / nyias cov ntaub ntawv, thiab siab dua hardness nyob rau hauv ib co formulations. Nyiam rau kev ua haujlwm precision (piv txwv li, UV nplaum, varnishes).
395nm ua: tuaj yeem nkag mus tau zoo dua rau cov ntaub ntawv tuab lossis xim xim hauv qee kis thiab feem ntau nyob rau hauv qis dua - cov nqi teeb tsa. Kev ua tau zoo nyob ntawm qhov tshwj xeeb photoinitiators hauv cov khoom.
Nco ntsoov xyuas cov khoom pom zoo wavelength.
4. Cov ntsiab lus siv tswv yim
| Yam | 365nm UV | 395nm UV ua |
|---|---|---|
| Qhov tshwm sim | Daj xiav -dawb | Liab liab / violet |
| Zoo tshaj rau | Kev tshawb nrhiav fluorescence, tshuaj xyuas (stains, forensics, txiaj, minerals), kev kho kom raug | Party/stage blacklights, general illumination, cost-sensitive siv |
| Pros | Purer UV, muaj zog fluorescence, tsis pom kev cuam tshuam | Pheej yig dua, pom cov nyhuv ci dua, yooj yim pom qhov pom lub teeb taw qhia |
| Cons | kim dua, pom qhov ci qis dua |
Kev ntxuav ntau dua, tsis muaj zog fluorescence rau qee yam haujlwm |

365NM UV Daim duab hauv qab no: (Dull blue-dawb)
395NM UV Daim duab hauv qab no: (Cim ntshav / violet)
5. Lwm cov ntaub ntawv
Kev nyab xeeb: Ob leeg yog UVA thiab kuj muaj kev nyab xeeb dua li UVB / UVC, tab sis tsis txhob cuam tshuam qhov muag / tawv nqaij. Siv cov iav tiv thaiv rau kev siv ntev.
Kev xaiv nyob ntawm qhov xav tau: Rau kev kuaj mob hnyav / tshuaj xyuas / kho → nyiam365nm ua. Rau kev lom zem blacklight tog lossis siv yooj yim →395nm uayog zoo thiab pheej yig dua. koj tuaj yeem pom cov ntaub ntawv ntxiv ntawmhttp://www.benweilight.com
