Kev luam tawm ntawm cov khoom siv ua yeeb yaj kiab raws li tus kheej nplaum tuaj yeem nthuav tawm cov teeb meem, thiab ink bleed yog ib qho teeb meem tshwm sim los ntawm cov tuam txhab luam ntawv. Ink poob yog hais txog qhov tsis zoo ntawm cov ntawv luam tawm txheej ntawm cov khoom siv vim yog cov yam ntxwv xws li qhov ntom ntom ntom ntom., UV curing tsis txaus, thiab ntau tus number case additives. Kev luam ntawv hnyav hnyav tsis tsuas yog cuam tshuam rau cov khoom zoo, tab sis txawm ua rau scrapping ntawm batch ntawm cov khoom. Hauv tsab xov xwm no, peb yuav tshawb txog peb qhov ua rau ntawm cov kua mem los ntshav ntawm cov ntawv luam tawm cov ntaub ntawv tus kheej nplaum thiab muab cov kev daws teeb meem zoo los daws qhov teeb meem no.
1. Tsawg nto nro ntawm cov ntaub ntawv zaj duab xis
Ib qho ntawm cov laj thawj tseem ceeb rau cov kua dej hauv cov ntawv luam tawm ntawm cov ntaub ntawv uas nws tus kheej-nplaum yog qhov tsis tshua muaj qhov nro ntawm zaj duab xis.. Feem ntau hais lus, qhov siab dua qhov nro, qhov zoo dua tus number case ceev tom qab luam ntawv. Tsis muaj teeb meem nrog qhov nro ntawm cov ntaub ntawv zoo li feem ntau, tab sis qhov nro ntawm cov ntaub ntawv zoo li zaj duab xis feem ntau tsis sib xws. Qhov no tsis tshua muaj qhov nro tuaj yeem ua rau cov kua nplaum tsis zoo, uas tuaj yeem ua rau txo tus number case droplet thiab luam ntawv zoo. Yog tias muaj tus lej poob thaum lub sijhawm luam ntawv, koj tuaj yeem siv tus cwj mem dyne los ntsuas qhov nro qhov nqi ntawm cov khoom. Feem ntau hais lus, cov ntaub ntawv nrog ib tug nto nro qis dua 38 datones yog feem ntau rau ink poob. Yuav daws qhov teeb meem no, xav txog cov kev daws teeb meem hauv qab no:
A. Kev kho saum npoo: siv cov txheej txheem kho saum npoo los txhim kho qhov nro ntawm cov khoom siv zaj duab xis. Qhov no tuaj yeem ua tiav los ntawm kev kho mob corona, Kev kho cov nplaim hluav taws lossis kev kho ntshav plasma, uas tuaj yeem hloov cov yam ntxwv saum npoo, nce wettability thiab txhawb nqa number case adhesion.
B. primer tsho tiv no: Siv lub tsho primer haum rau cov khoom siv ua yeeb yaj kiab ua ntej luam ntawv. Primers pab tsim kev sib raug zoo ntawm tus cwj mem thiab qhov chaw ntawm cov khoom, txhim kho tus cwj mem adhesion thiab txo qhov muaj feem ntawm cov kua nplaum poob. Tham nrog koj tus neeg muab txheej txheej los xaiv cov primer tsim nyog uas sib haum nrog cov khoom siv zaj duab xis thiab tus number case formulation. Qee cov tuam txhab luam ntawv tshaj lij tseem yuav ncaj qha siv cov ntaub ntawv PET tus kheej nplaum rau kev luam ntawv. Cov txheej txheem hloov cov txheej txheem ntub dej ntawm PET cov ntaub ntawv tus kheej nplaum, thiab kev ua tau zoo yog ruaj khov, thiab lub firmness ntawm tus number case txheej tuaj yeem txhim kho tau zoo.
2. UV curing tsis txaus
UV curing tsis txaus kuj tseem yuav ua rau cov kua dej hauv cov kua dej thaum luam tawm cov ntaub ntawv ntawm tus kheej-nplaum. Kev kho tsis tiav yuav ua rau cov kua nplaum txheej uas tsis ua tiav qhov zoo tshaj plaws hardness thiab adhesion, ua rau tsis zoo smearing thiab ceev ceev. Kev kho tsis tiav txhais tau hais tias txheej txheej ntawm cov ntawv luam ntawv tau qhuav thiab kho, tab sis sab hauv yog tsis kho kiag li. Tus cwj mem poob los ntawm qhov xwm txheej no feem ntau tshwm sim hauv kev luam ntawv ntawm cov qauv loj hauv cheeb tsam. Qhov no yog vim cov qauv loj hauv cheeb tsam siv ntau tus cwj mem, thiab sab hauv ntawm tus number case txheej tsis yog li yooj yim los kho tag nrho. Yuav daws qhov teeb meem no, koj tuaj yeem xa mus rau cov kev daws teeb meem hauv qab no:
A. UV Intensity thiab Dose: Xyuas kom tseeb tias UV curing system yog calibrated kom zoo thiab xa txaus UV siv thiab ntau npaum. Saib xyuas thiab kho cov qib UV siv kom ua tiav qhov kev kho kom zoo rau cov cwj mem tshwj xeeb thiab cov khoom siv zaj duab xis raug siv. Piv txwv li, Cov qauv tsaus nti nqus ntau lub teeb UV thiab feem ntau xav tau ntau lub zog kom qhuav tag. Nrog tus cwj mem thiab cov cuab yeej siv rau kev pom zoo UV curing tsis.
B. Curing lub sij hawm thiab kub: optimize lub sij hawm curing thiab qhov kub thiab txias los xyuas kom meej txaus txaus thiab xyuas kom meej tias cov number case txheej yog tag nrho kho. Nrog rau tus neeg tsim khoom tus cwj mem cov lus qhia rau kev pom zoo kho tsis tau thiab kho raws li qhov kev luam ntawv thiab cov khoom siv.
C. Kev pab lub neej ntawm UV teeb: Tam sim no, kev pab cuam lub neej ntawm UV teeb ntawm toppan printing khoom nyob nruab nrab ntawm 800 thiab 1000 teev. Yog hais tias lub teeb tsis tau hloov thaum lub sij hawm rated lub neej, nws yog ib qho yooj yim ua rau tus number case qhuav. Yog li ntawd, thaum hloov lub UV teeb lub raj, Nws yog ib qho tsim nyog los ua cov ntaub ntawv ntxaws, thiab thaum UV teeb lub raj mus txog qhov kev pab cuam lub neej, nws yuav tsum tau hloov nyob rau hauv lub sij hawm.
3. Ntau tus cwj mem additives
Lub xub ntiag ntawm ntau tus number case additives yuav ua rau tus number case poob thaum luam ntawv zaj duab xis-hom self-adhesive cov ntaub ntawv. Nyob rau hauv cov txheej txheem luam ntawv, cov luam ntawv number case feem ntau ntsib cov teeb meem ntawm thickening, siab viscosity thiab tsis zoo inking. Yog li ntawd, ntau tus neeg teb xov tooj yuav xaiv ntxiv cov kua roj vanish los txhim kho fluidity ntawm luam ntawv number case. Txawm li cas los, yog tias cov kua roj vanish siv tsis raug, Nws yog ib qho yooj yim heev los cuam tshuam tus number case viscosity, nto nro thiab adhesion kev ua tau zoo, ua rau ink poob. Thov xav txog cov kev daws teeb meem hauv qab no los daws qhov teeb meem no:
A. Ink Formulations: Tshawb xyuas thiab ua kom zoo dua cov qauv ntawm tus number case nrog lub hom phiaj ntawm kev txo cov khoom siv ntau dhau. Vim tsis yog txhua yam ntaub ntawv tuaj yeem ua tau zoo nrog cov inks, nrhiav tus cwj mem zoo yog qhov ua tau zoo tshaj plaws los ntawm kev ua haujlwm ze nrog tus neeg muag khoom tus cwj mem los tsim cov qauv tsim tus cwj mem uas sib npaug ntawm tus cwj mem thiab txo qis kev pheej hmoo ntawm tus number case poob..
B. Kev ntsuam xyuas kev sib raug zoo: Xa cov ntaub ntawv mus rau tus neeg muab tus cwj mem rau kev kuaj xyuas kom ntseeg tau tias tus number case additive siv yog sib xws nrog cov khoom siv zaj duab xis thiab txheej txheem luam ntawv.. Kev ntsuam xyuas kev sib raug zoo yog ua los ntawm tus cwj mem thiab cov ntaub ntawv zaj duab xis los txiav txim siab txog kev sib cuam tshuam lossis kev tsis sib haum xeeb uas yuav ua rau tus number case poob. Ntsuam xyuas cov qauv sib txawv thiab kho cov qib ntxiv kom pom qhov zoo tshaj plaws ua ke uas muab cov adhesion zoo thaum txo tus number case dripping.
Xaus
Kev kov yeej cov teeb meem ntawm tus number case droplet printing nyob rau hauv zaj duab xis-raws li tus kheej-nplaum cov ntaub ntawv yuav tsum tau ib tug multifaceted mus kom ze. Los ntawm kev hais txog qhov ua rau muaj qhov tsis sib haum xeeb, Tsis txaus UV curing thiab ntau tus number case additives, Cov tshuab luam ntawv tuaj yeem txhim kho tus cwj mem adhesion thiab ua tiav cov ntawv luam zoo dua. Siv cov kev kho saum npoo los yog cov tsho primer los txhim kho qhov nro, optimize UV curing parameters kom ua tiav tag nrho cov number case kho, thiab nplua-tune ink formulations kom txo tau siv cov additives ntau tshaj. Los ntawm kev siv cov kev daws teeb meem no, cov tuam txhab lag luam tuaj yeem kov yeej cov kev sib tw ntawm tus lej poob thiab tsim cov ntawv luam tawm zoo ntawm cov ntaub ntawv uas nws tus kheej-nplaum.
