1. nce lub zog ntawm UV curing teeb: ntawm feem ntau cov substrates, ua kom lub zog ntawm UV curing yuav ua rau kom cov adhesion ntawm UV number case thiab substrate.Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog nyob rau hauv ntau txheej luam ntawv: thaum pleev xim rau txheej thib ob ntawm UV txheej, thawj txheej ntawm UV number case yuav tsum tau kho kom zoo.Txwv tsis pub, ib zaug ob txheej ntawm UV number case tau luam tawm ntawm qhov chaw ntawm lub substrate, lub hauv paus UV number case yuav tsis muaj sijhawm los kho ntxiv.Tau kawg, ntawm qee qhov substrates, dhau kev kho tuaj yeem ua rau UV inks tawg thaum txiav.
2. txo cov luam ntawv ceev: txo cov luam ntawv ceev thaum ua kom lub zog UV teeb tuaj yeem txhim kho qhov adhesion ntawm UV number case.Ntawm UV flat-panel inkjet tshuab luam ntawv, cov nyhuv luam ntawv kuj tuaj yeem txhim kho los ntawm ib txoj kev luam ntawv (tsis yog rov qab thiab tawm mus).Txawm li cas los xij, ntawm lub substrate uas yooj yim rau curl, cua sov thiab deceleration kuj yuav ua rau lub substrate curl.
3. ncua sij hawm kho: nws yuav tsum tau muab sau tseg tias UV number case yuav kho tom qab luam ntawv.Tshwj xeeb tshaj yog nyob rau thawj 24 teev tom qab luam ntawv, qhov no yuav txhim kho UV adhesion.Yog tias ua tau, ncua cov txheej txheem ntawm kev txiav cov substrate kom txog rau thaum nees nkaum plaub teev tom qab UV luam ntawv.
4. xyuas seb lub teeb UV thiab nws cov khoom siv puas ua haujlwm ib txwm: yog tias qhov adhesion txo qis ntawm lub substrate uas yooj yim txuas rau lub sijhawm zoo tib yam, nws yuav tsum xyuas seb lub teeb UV thiab nws cov khoom siv puas ua haujlwm li qub.Tag nrho cov UV tua teeb muaj qee yam kev pab cuam lub neej (feem ntau, lub neej kev pabcuam yog li 1000 teev).Thaum lub neej kev pab cuam ntawm UV curing teeb tshaj nws lub neej kev pab cuam, nrog rau maj mam decomposition ntawm lub teeb lub electrode, lub puab phab ntsa ntawm lub teeb yuav tso, lub transparency thiab UV transmittance yuav maj mam tsis muaj zog, thiab lub hwj chim yuav zoo heev txo.Tsis tas li ntawd, yog tias lub teeb pom kev ntawm UV curing teeb yog qias neeg dhau lawm, lub zog cuam tshuam ntawm UV kho lub teeb yuav ploj mus (lub zog cuam tshuam tuaj yeem suav txog li 50% ntawm lub zog ntawm tag nrho UV kho teeb), uas tseem yuav ua rau lub teeb pom kev ntawm UV curing teeb. ua rau txo qis ntawm lub zog ntawm UV kho teeb.Kuj tseem muaj qee lub tshuab luam ntawv uas nws UV kho teeb lub zog teeb tsa tsis tsim nyog.Txhawm rau kom tsis txhob muaj tus cwj pwm tsis zoo uas tshwm sim los ntawm lub zog tsis txaus ntawm UV kho lub teeb, nws yog ib qho tsim nyog los xyuas kom meej tias UV curing teeb ua haujlwm nyob rau hauv lub neej kev pab cuam, thiab UV curing teeb uas tau dhau lub neej kev pab cuam yuav tsum tau hloov nyob rau hauv lub sij hawm.UV curing teeb yuav tsum tau muab ntxuav tsis tu ncua kom ntseeg tau tias lub reflector huv si thiab txo qhov poob ntawm lub zog ntawm lub zog.
5. txo tus number case txheej thickness: vim hais tias cov nyhuv adhesion muaj feem xyuam rau cov degree ntawm UV number case curing, txo tus nqi ntawm UV number case yuav txhawb cov adhesion rau substrate.Piv txwv li, nyob rau hauv tus txheej txheem ntawm loj-thaj chaw luam ntawv, vim lub loj npaum li cas ntawm number case thiab cov tuab number case txheej, txheej txheej ntawm tus number case solidifies thaum lub hauv qab txheej yog tsis tag nrho solidified thaum UV curing.Thaum tus number case yog pseudo qhuav, qhov adhesion ntawm tus number case substrate thiab lub substrate nto yuav tsis zoo, uas yuav ua rau poob ntawm tus number case txheej ntawm cov ntawv luam tawm vim yog qhov sib txhuam ntawm cov txheej txheem tom ntej.Thaum luam ntawv loj-qhov chaw nyob, ua tib zoo saib xyuas kom nruj me ntsis tswj tus number case.Rau qee qhov chaw xim luam ntawv, nws yog qhov zoo dua los ua kom cov xim tsaus nti thaum sib xyaw cov number case, kom cov number case sib sib zog nqus thiab nyias luam ntawv tuaj yeem nqa tawm thaum lub sijhawm luam ntawv, thiaj li ua kom muaj zog ntawm tus number case thiab ua kom cov firmness ntawm cov number case txheej.
6. cua sov: nyob rau hauv kev lag luam luam ntawv, nws raug nquahu kom sov lub substrate ua ntej UV curing ua ntej luam tawm lub substrate uas yog ib qho nyuaj rau adhere.Tom qab cua sov nrog ze-infrared lub teeb los yog deb-infrared lub teeb rau 15-90 vib nas this, lub adhesion ntawm UV number case ntawm lub substrate yuav muaj zog.
7. ink adhesion promoter: tus cwj mem adhesion txhawb nqa tuaj yeem txhim kho qhov adhesion ntawm tus number case thiab cov khoom.Yog li ntawd, yog tias UV number case tseem muaj teeb meem adhesion ntawm lub substrate siv cov txheej txheem saum toj no, ib txheej ntawm adhesion txhawb nqa tuaj yeem txau rau saum npoo ntawm substrate.
Kev daws teeb meem ntawm qhov tsis zoo UV adhesion ntawm cov yas thiab hlau nto:
Cov kev daws teeb meem zoo rau cov teeb meem tsis zoo ntawm cov xim UV ntawm nylon, PP thiab lwm yam yas thiab stainless hlau, zinc alloy, aluminium alloy thiab lwm yam hlau nto yog txau ib txheej ntawm Jisheng adhesion kho tus neeg sawv cev ntawm substrate thiab xim txheej rau. txhim kho qhov adhesion ntawm cov khaubncaws sab nraud povtseg.
