Raws li kev lag luam xav tau kev ruaj ntseg, kev ua tau zoo thiab kev ua tau zoo txuas ntxiv mus, cov ntawv sau thiab ntim cov hloov pauv tau saib rau UV LED cov kev daws teeb meem kom tau raws li lawv cov kev xav tau kho. Cov thev naus laus zis tsis yog thaj chaw tshwj xeeb ntxiv lawm vim LEDs tau dhau los ua cov thev naus laus zis kho tshuab hauv ntau daim ntawv thov luam ntawv.
UV LED cov tuam txhab lees paub tias kev siv UV LED thev naus laus zis ua rau cov tuam txhab txo qis lawv cov pa roj carbon hneev taw thiab nce cov txiaj ntsig los ntawm kev txo qis kev siv hluav taws xob, tiv thaiv kev ua qias tuaj thiab txo cov khoom pov tseg. Txhim kho rauUV LED curingtuaj yeem txo cov nqi hluav taws xob los ntawm 50% -80% thaum hmo ntuj. Nrog rau kev rov qab los ntawm kev nqis peev tsawg dua ib xyoos, cov nqi hluav taws xob rov qab thiab cov kev txhawb zog hauv lub xeev, ntxiv rau kev txuag hluav taws xob, tuaj yeem txo tus nqi ntawm kev kho dua tshiab rau cov khoom siv LED kom ruaj khov.
Kev nce qib ntawm LED thev naus laus zis kuj tau txhawb nqa nws txoj kev siv. Cov khoom no muaj txiaj ntsig zoo dua li cov tiam dhau los, thiab lawv cov kev txhim kho txuas ntxiv mus rau inks thiab substrates thoob plaws ntau lub lag luam luam ntawv, suav nrog cov inkjet, tshuaj ntsuam luam ntawv, flexo, thiab offset.
Cov tiam tshiab ntawm UV thiab UV LED curing systems muaj txiaj ntsig zoo dua li lawv cov neeg ua ntej, yuav tsum muaj lub zog tsawg dua kom ua tiav cov txiaj ntsig UV tib yam. Txhim kho qhov qub UV system lossis txhim kho UV xovxwm tshiab tuaj yeem ua rau kev txuag hluav taws xob tam sim rau cov tshuab luam ntawv.
Kev lag luam tau ntsib kev loj hlob tseem ceeb hauv kaum xyoo dhau los, tau tsav los ntawm kev txhim kho hauv kev ua tau zoo thiab nce kev tswj hwm. Kev siv technology thiab lub zog txoj cai nce qib dhau los 5-10 xyoo dhau los tau ua rau muaj kev txaus siab rau LED kho, ua rau cov tuam txhab los txhim kho qhov hloov pauv ntawm lawv cov txheej txheem kho. Ntau lub tuam txhab tau hloov pauv los ntawm cov txheej txheem UV ib txwm siv rau LED lossis siv txoj hauv kev sib xyaw, siv ob qho tib si UV thiab LED thev naus laus zis ntawm ib qho xovxwm los txhawb cov thev naus laus zis zoo rau txhua daim ntawv thov. Piv txwv li, LED feem ntau siv rau xim dawb lossis xim tsaus, thaum UV yog ua haujlwm rau varnishing.
Kev siv UV LED curing tau ntsib ib lub sijhawm ntawm kev loj hlob sai, feem ntau vim yog kev txhim kho ntawm kev lag luam zoo pib encapsulation thiab kev txhim kho hauv LED thev naus laus zis. Kev siv cov khoom siv hluav taws xob zoo dua thiab cov qauv tsim kom txias tuaj yeem ua kom muaj zog irradiance ntau dua ntawm qis lossis tib lub zog siv, yog li txhim kho kev ruaj ntseg ntawm cov cuab yeej siv.
Kev hloov pauv mus rau LED curing muaj ntau qhov zoo ntawm cov kab ke ib txwm muaj. LEDs muab cov kev daws teeb meem zoo tshaj plaws rau kev kho cov inks, tshwj xeeb tshaj yog cov xim dawb thiab cov xim pigmented, nrog rau cov nplaum nplaum, cov ntawv ci laminates, C-square coatings thiab cov txheej txheem thicker. Qhov ntev UVA wavelengths emissions los ntawm LEDs muaj peev xwm nkag mus tob rau hauv formulations, kis tau yooj yim los ntawm films thiab foils, thiab yog tsawg absorbed los ntawm cov xim tsim pigments. Qhov no ua rau muaj zog ntau dua rau hauv cov tshuaj tiv thaiv tshuaj, uas ua rau muaj kev txhim kho opacity, kev kho kom zoo dua thiab cov kab ntau lawm ceev.
UV LED tso zis tseem zoo ib yam thoob plaws hauv lub neej ntawm cov khoom, whereas lub arc teeb tso zis txo qis los ntawm thawj raug. Nrog UV LEDs, muaj kev ruaj ntseg ntau dua nyob rau hauv qhov zoo ntawm cov txheej txheem kho thaum ua haujlwm tib yam li ob peb lub hlis, thaum kho cov nqi raug txo. Qhov no ua rau muaj kev daws teeb meem tsawg dua thiab muaj kev hloov pauv tsawg dua hauv cov zis vim yog cov khoom siv degradation. Cov xwm txheej no ua rau muaj kev ruaj ntseg ntawm cov txheej txheem luam ntawv uas muaj los ntawm UV LEDs.
Rau ntau tus processors, hloov mus rau LEDs sawv cev rau kev txiav txim siab ceev faj.UV LED curing systemsmuab cov tshuab luam ntawv thiab cov chaw tsim khoom nrog cov txheej txheem kev ruaj ntseg thiab kev saib xyuas lub sijhawm tiag tiag, muab cov kev daws teeb meem ruaj khov thiab txhim khu kev qha rau lawv cov kev xav tau ntau lawm. Cov thev naus laus zis tshiab tuaj yeem hloov kho kom haum nrog cov qauv tshiab hauv kev tsim khoom. Muaj kev xav tau ntau ntxiv los ntawm cov neeg siv khoom rau cov txheej txheem tswj xyuas los ntawm kev saib xyuas lub sijhawm ntawm UV LED kho cov teeb, txhawm rau txhawb kev lag luam 4.0 kev tsim khoom zoo dua. Ntau ntawm lawv ua haujlwm teeb pom kev zoo, tsis muaj teeb pom kev lossis cov neeg ua haujlwm thaum lub sijhawm ua haujlwm, yog li nws yog qhov tseem ceeb uas kev saib xyuas kev ua haujlwm nyob deb muaj nyob ib ncig ntawm lub moos. Hauv cov chaw ua haujlwm nrog tib neeg cov neeg ua haujlwm, cov neeg siv khoom xav tau kev ceeb toom tam sim ntawm txhua qhov teeb meem nrog cov txheej txheem kho kom txo qis qis qis thiab pov tseg.
