Nyob rau hauv inkjet luam ntawv, kev siv UV LED curing teeb tau txais txiaj ntsig zoo heev vim lawv txhim kho kev ua tau zoo thiab kev ua tau zoo hauv kev kho inks. Txawm li cas los xij, txhawm rau txhawm rau txhawm rau kho kom zoo, nws yog ib qho tseem ceeb uas yuav tsum tau soj ntsuam kev siv UV ntawm UV teeb tsis tu ncua. Qhov kev coj ua no yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab sib xws ntawm cov txheej txheem kho thaum luam ntawv.
UV LED curing teebyog dav siv nyob rau hauv kev lag luam luam ntawv rau lawv lub peev xwm los kho cov inks thiab coatings tam sim ntawd, ua rau lub sij hawm ntau lawm thiab txhim kho kev luam ntawv zoo. Cov teeb no tso tawm lub teeb ultraviolet, uas pib ua cov tshuaj tiv thaiv photochemical hauv tus cwj mem, ua rau nws kho thiab ua raws li cov substrate. Txawm li cas los xij, qhov ua tau zoo ntawm cov txheej txheem kho yog ncaj qha nyob ntawm UV siv los ntawm lub teeb.
Ib qho ntawm cov laj thawj tseem ceeb vim li cas tus cwj mem curing yuav tsum tau kuaj xyuas UV teeb ntau zaus yog qhov ua rau degradation dhau sijhawm. UV LED teeb pom kev txo qis hauv UV cov zis thaum lawv muaj hnub nyoog, uas tuaj yeem muaj kev cuam tshuam loj rau kev kho kom zoo. Los ntawm kev saib xyuas kev siv UV tsis tu ncua, cov tshuab luam ntawv tuaj yeem txheeb xyuas qhov kev poob qis hauv cov zis thiab ua cov kev ntsuas ua haujlwm kom tswj tau qhov ua tau zoo ntawm lub teeb.
Tsis tas li ntawd, kev hloov pauv hauv UV siv tuaj yeem tshwm sim vim muaj qhov xwm txheej xws li kub, av noo thiab kev ua haujlwm. Cov kev hloov pauv no tuaj yeem cuam tshuam cov txheej txheem kho, ua rau tsis sib xws hauv kev luam ntawv zoo thiab adhesion. Los ntawm kev saib xyuas UV siv, cov tshuab luam ntawv tuaj yeem hloov kho kom ntseeg tau tias qhov kev kho kom zoo nyob ruaj khov, tiv thaiv cov teeb meem nrog tus cwj mem adhesion thiab luam ntawv ntev.
Ntxiv nrog rau kev tswj xyuas kev kho kom zoo, UV teeb tswj kev siv lub teeb yog qhov tseem ceeb kom ua raws li cov qauv kev lag luam thiab cov cai. Ntau daim ntawv thov luam ntawv xav tau cov tshuaj UV tshwj xeeb kom ua tiav cov txiaj ntsig xav tau. Kev saib xyuas kev siv UV tsis tu ncua tso cai rau cov tshuab luam ntawv kom paub meej tias lub teeb ua haujlwm raws li qhov xav tau, ua kom ntseeg tau tias cov khoom luam tawm ua tau raws li cov qauv zoo thiab cov kev cia siab ntev.
Txhawm rau saib xyuas qhov kev siv UV ntawm UV LED tua teeb kom zoo, cov tshuab luam ntawv tuaj yeem siv UV radiometers, uas yog cov cuab yeej tshwj xeeb tsim los ntsuas UV cov zis. Cov cuab yeej no muab kev nyeem ntawv tseeb ntawm UV siv, tso cai rau cov tshuab luam ntawv los ntsuas kev ua haujlwm ntawm lawv cov teeb kho thiab txiav txim siab txog kev saib xyuas thiab kev hloov kho.
Hauv cov ntsiab lus, cov nyhuv curing ntawm cov ntawv luam tawm yog nyob ntawm qhov kev siv UV ntawm lub tshuab luam ntawv.UV LED systems. Los ntawm kev tshuaj xyuas UV siv ntau zaus, cov tshuab luam ntawv tuaj yeem tswj xyuas qhov ua tau zoo ntawm cov txheej txheem kho, hais txog qhov muaj peev xwm degradation lossis kev hloov pauv, thiab xyuas kom ua raws li cov qauv kev lag luam. Thaum kawg, qhov kev coj ua no ua rau muaj txiaj ntsig zoo sib xws, txhim kho adhesion thiab tag nrho kev vam meej ntawm inkjet luam ntawv daim ntawv thov.
