Laminating zaj duab xis yog dav siv nyob rau hauv luam ntawv, ntim, thiab archival preservation industries. Nws lub luag haujlwm tseem ceeb yog muab kev tiv thaiv, kev zoo nkauj, thiab ua haujlwm ntev rau cov ntawv, cov ntaub ntawv luam tawm, lossis cov khoom ntim. Txawm li cas los xij, ntau tus neeg siv khoom ntsib teeb meem xws li delamination, tev, lossis ntug curling thaum siv. Qhov no tsis tsuas yog cuam tshuam rau cov khoom muag tab sis kuj tuaj yeem ua rau cov khoom pov tseg thiab cov nqi ua haujlwm thib ob.
Raws li tus kws tshaj lijlaminating zaj duab xis manufacturers, YIDU, raws li kev tsim khoom ntau xyoo, tau sau cov ncauj lus kom ntxaws thiab ceev faj txog kev tiv thaiv laminating zaj duab xis delamination, pab cov neeg yuav khoom thiab xaus- cov neeg siv txhim kho lamination cuam tshuam thiab ruaj khov.
1. Qhov laj thawj tseem ceeb ntawm delamination
1.1 Substrate Surface Contamination lossis Roj Residue
Yog hais tias qhov saum npoo ntawm cov ntaub ntawv luam tawm los yog daim ntawv muaj cov cwj mem tsis qhuav, plua plav, cov ntiv tes roj, lossis lwm yam khoom paug, nws yuav cuam tshuam qhov kev sib raug zoo ntawm cov nplaum nplaum kub los yog siab heev - nplaum nplaum rau lub substrate.
Qhov teeb meem no tshwj xeeb tshaj yog rau cov luam ntawv digital, inkjet luam ntawv, lossis kua roj vanish -coated ntawv.
1.2 Tsis tsim nyog Kub- nias Kub
Tsis tshua muaj kub yuav ua rau kub yaj nplaum nplaum tsis yaj tag, ua rau tsis txaus adhesion thiab delamination; Qhov kub thiab txias heev tuaj yeem ua rau cov nplaum nplaum ntws ntau dhau, ua rau shrinkage lossis delamination.
1.3 Siab tsis sib xws
Kev faib tawm tsis sib xws lossis tsis tshua muaj siab yuav ua rau qee qhov chaw ntawm cov nplaum tsis tuaj yeem ua raws li cov substrate.
Rau cov ntawv loj - hom ntawv lossis cov ntawv tuab, tsis txaus siab hauv zos tuaj yeem yooj yim ua npuas thiab voids, ua rau delamination.
1.4 High Substrate Moisture Content
Daim ntawv los yog duab los qhia absorbs noo noo thiab nthuav, uas yuav txo tau qhov adhesion ntawm zaj duab xis txheej thiab substrate, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob ntawm high humidity los yog tseem ceeb raws caij nyoog hloov.
1.5 Zaj duab xis Khoom Zoo lossis Adhesive Txheej Teeb meem
Tsawg- zaj duab xis zoo, txheej tsis sib xws, lossis zaj duab xis muaj hnub nyoog yuav ua rau muaj adhesion tsis txaus.
Cov khoom sib txawv ntawm cov yeeb yaj kiab muaj qhov sib txawv ntawm cov nplaum nplaum los yog siab heev - cov khoom nplaum nplaum; Kev sib piv tsis raug ntawm qhov kub, siab, thiab ceev tuaj yeem ua rau delamination.
2. Cov tswv yim los tiv thaiv delamination
2.1 Khaws lub substrate nto huv si
Txoj Kev Ua Haujlwm
Ua ntej lamination, xyuas kom lub ntsej muag ntawm daim ntawv, cov ntaub ntawv luam tawm, lossis cov khoom ntim tsis muaj plua plav, roj, cov ntiv tes, lossis cov khoom xoob.
Rau glossy coated ntawv los yog inkjet luam ntawv cov ntaub ntawv, ntxuav lub nto nrog ib tug huv si, mos ntaub los yog compressed cua.
2.2 Tswj qhov kub xovxwm kub
Txoj Kev Ua Haujlwm
Teem lub siab kub xovxwm kub raws li hom zaj duab xis:
BOPP zaj duab xis: 100-130 degree
PET zaj duab xis: 110-150 degree
Rau cov yeeb yaj kiab tuab lossis loj - cov ntaub ntawv hom, cua sov lossis preheat lub substrate hauv cov ntu kom tsis txhob muaj cua sov hauv zos.
2.3 Kho Siab thiab Ceev
Txoj Kev Ua Haujlwm
Lub siab ntawm cov chais rau ntawm cov xovxwm kub los yog laminator yuav tsum tau muab sib npaug. Tsis tshua muaj siab yuav ua rau thaj chaw delamination, thaum lub siab dhau heev yuav ua rau cov yeeb yaj kiab stretching ntau dhau.
Lamination ceev yuav tsum sib phim nrog qhov kub thiab txias: 0.5-1 m / min rau cov ntawv me me, 0.3-0.7 m / min rau ntim loj.
2.4 Tswj substrate humidity thiab ib puag ncig tej yam kev mob
Txoj Kev Ua Haujlwm
Cov av noo ntawm daim ntawv lossis cov duab los qhia yuav tsum tswj tsis pub dhau 4-6%.
Nyob rau hauv high humidity los yog raws caij nyoog damp puag ncig, qhuav kev kho mob yuav ua tau ua ntej lamination.
Tsis txhob khaws cov khoom laminated rau lub sijhawm ntev hauv qhov chaw muaj av noo.
2.5 Xaiv High-Zoo zaj duab xis thiab nplaum txheej
Txoj Kev Ua Haujlwm
Xaiv cov khoom uas muaj cov yeeb yaj kiab tuab tuab, cov nplaum nplaum zoo ib yam, thiab ua kom sov zoo.
2.6 Siv cov yeeb yaj kiab ua haujlwm lossis los tiv thaiv -Delamination Coated Films
Txoj Kev Ua Haujlwm
Rau siab-cov ntaub ntawv luam tawm kawg lossis loj- hom ntim ntim, xaiv cov ntaub ntawv zaj duab xis nrog cov tshuaj tiv thaiv - delamination.
Coated films tuav zoo adhesion nyob rau hauv ob qho tib si kub thiab txias nias, thaum txo qhov kev pheej hmoo ntawm wrinkling thiab bubbling.
Laminating zaj duab xisdelamination feem ntau yog tshwm sim los ntawm substrate contamination, kub tsis zoo, tsis sib xws siab, cov av noo ntau, thiab cov teeb meem ntawm zaj duab xis zoo. Rau txoj hauv qab no tuaj yeem tiv thaiv delamination zoo:
Khaws lub substrate kom huv si
Tswj kub - nias kub
Kho siab thiab ceev
Tswj substrate humidity thiab tej yam kev mob
Xaiv cov khoom zoo - cov ntaub ntawv zoo thiab cov nplaum nplaum
Siv cov yeeb yaj kiab ua haujlwm lossis cov yeeb yaj kiab tiv thaiv - delamination coated
