Master ob peb lub ntsiab lus yooj yim los daws cov teeb meem 'cov teeb meem nyuaj' nrog UV Inks
Ua raws li tsab xov xwm dhau los (Yuav ua li cas xaiv thiab siv UV Inks? Lub Txheej Txheem Ceev), tus sau luv piav qhia qee cov ntsiab lus tseem ceeb thiab kev ceev faj thaum xaiv thiab siv UV inks. Txawm li cas los xij, thaum siv UV inks, teeb meem feem ntau tshwm sim, xws li kev kho tsis zoo, tsis muaj zog adhesion, thiab number case piling, uas tuaj yeem cuam tshuam cov tuam txhab luam ntawv. Hauv tsab xov xwm no, tus sau yuav luv luv tham txog cov teeb meem no.
01
Poor Curing Phenomenon thiab Solutions
Thaum UV number case tsis kho tag nrho, cov number case txheej muaj cov adhesion tsis zoo, uas tuaj yeem ua rau tus number case lo rau sab nraum qab ntawm cov ntawv uas nyob ib sab thaum luam ntawv, ua rau muaj smudges. Nyob rau tib lub sijhawm, tus cwj mem saum npoo yuav tsis tshua muaj kev cuam tshuam rau kev puas tsuaj thiab tuaj yeem khawb tau yooj yim thaum kev tshaj tawm - ua haujlwm lossis siv, cuam tshuam rau kev luam ntawv zoo.
Txoj hauv kev zoo tshaj plaws los daws qhov kev kho tsis tiav ntawm UV number case yog hloov mus rau UV number case nrog kev kho kom nrawm dua. Koj tseem tuaj yeem siv tus cwj mem nrog cov xim ntau dua thiab siv cov xim nyias nyias kom ua tiav cov xim uas xav tau, uas txhim kho kev kho kom zoo thiab ua kom tiav cov number case curing. Qee qhov xwm txheej, yam tsis hloov tus cwj mem, ntxiv me me ntawm cov roj nplua nyeem ntxiv los yog tus pab kho tuaj yeem txhim kho UV number case curing efficiency thiab ua tiav kev kho tiav. Txawm li cas los xij, feem ntau, ntxiv cov tshuaj ntxiv tsis pom zoo kom tsis txhob muaj tshuaj lom neeg.
02
Tsis muaj zog Adhesion Phenomenon thiab Solutions
Cov cwj pwm tsis zoo tsis yog ib txwm tshwm sim los ntawm tus number case nws tus kheej; Nws yog ze ze rau cov khoom nto ntawm lub substrate. Thaum hloov lossis kho tus cwj mem tsis daws qhov teeb meem thiab hloov lub substrate tsis yog ib qho kev xaiv, cov tuam txhab luam ntawv muaj ob txoj kev xaiv los ntawm.
Tshuaj 1: Ua ntej luam cov xim number case, siv lub pob tshab nruab nrab nrog adhesion zoo heev siv luam ntawv, uas txhim kho cov khoom saum npoo ntawm substrate thiab tso cai rau UV number case kom ua raws li qhov zoo. Txoj kev no yog siv rau hauv thawj chav tsev ntawm lub tshuab luam ntawv siv UV curing.
Kev daws 2: Coated lub substrate nto nrog dej -raws li cov kua roj vanish ua ntej luam ntawv los daws cov teeb meem adhesion xws li number case splattering los yog kis. Cov dej-raws li cov kua roj vanish yog siv los ntawm cov menyuam txheej thiab qhuav nrog infrared. Cov tshuaj no yog tsim los rau substrates xws li hlau los yog holographic cardboard, uas tsis ruaj tsis khov UV number case adhesion.
03
Ink Piling Issue Analysis thiab Solutions
Ink piling yog hais txog tus number case nyob rau hauv daim pam, luam ntawv phaj, thiab chais, ua rau cov cwj mem tsis zoo thiab ua rau cov duab tsis pom ntawm cov khoom luam tawm (saib daim duab 4). Cov laj thawj tseem ceeb muaj xws li tus cwj pwm tsis zoo, hloov tus cwj mem tsis zoo, ntawv hmoov av sib xyaw nrog tus number case, tsis txaus ink fineness, thiab hauv offset printing, emulsification ntawm tus number case los ntawm cov kav dej.
Yuav kom daws tau tus number case piling, siv tack reducers los yog anti- teem- tawm cov neeg ua hauj lwm los kho tus number case tack thiab viscosity. Rau kev luam ntawv offset, siv tus cwj mem nrog dej zoo thiab tsis txhob siv dej ntau thaum luam ntawv.
Feem ntau, qhov ceev ntawm UV number case kho, qhov nyuaj ntawm tus number case txheej nto, qhov qis dua qhov yooj yim, qhov tsis muaj zog adhesion ntawm lub substrate, thiab qhov qis ntawm cov ntawv luam tawm. Tsis tas li ntawd, ntau tus neeg muab tus cwj mem muab cov inks haum rau cov khoom sib txawv ntawm cov substrate nto.
Hauv luv luv, cov tuam txhab luam ntawv yuav tsum xav txog txhua yam ua tib zoo thaum xaiv thiab siv UV inks thiab txiav txim siab sib npaug. Thaum muaj teeb meem luam ntawv tshwm sim, nws yog ib qho tseem ceeb rau lub hom phiaj kev daws teeb meem.
