Qee cov neeg siv khoom yuav muaj teeb meem xws li cov nyhuv laminating tsis zoo thaum sivthermal lamination zaj duab xis. Raws li cov txheej txheem kev coj ua, qhov zoo ntawmzaj duab xis sib xyawlaminating feem ntau cuam tshuam los ntawm 3 yam: kub, siab thiab ceev. Yog li ntawd, kev tswj xyuas kev sib raug zoo ntawm 3 yam tseem ceeb yog qhov tseem ceeb rau kev ua kom zoo ntawmpre-txheej zaj duab xislamination thiab nws qhov cuam tshuam rau kev tsim khoom hauv qab.
Kub:
Nws yog thawj qhov tseem ceeb. Adhesive siv rau lubThaum tshav kub kub laminating zaj duab xisyog kub yaj nplaum. Qhov ntsuas kub txiav txim siab lub xeev melting ntawm cov nplaum nplaum kub, nws qhov kev ua tau zoo, qhov muaj peev xwm ntawm qhov sib txawv ntawm cov nplaum nplaum kub thiab cov yeeb yaj kiab, txheej number case, daim ntawv substrate, thiab crystallinity ntawm kub yaj nplaum nplaum. Tsuas yog los ntawm kev tswj xyuas qhov kub thiab txias hauv thaj chaw ua haujlwm tuaj yeem ua kom cov khoom kub yaj nplaum nplaum txheej ntawm zaj duab xis yuav tsum tau yaj tag rau hauv lub xeev ntws, nrog rau cov dej kom zoo, kom ua tiav ntub dej thiab adhesion rau saum npoo ntawm cov ntawv luam tawm. Nyob rau tib lub sijhawm, nws tau lees paub tias yuav kho tam sim tom qab lamination, yog li cov khoom laminated yog du thiab ci, cov nplaum txheej yog zoo fused, tsis muaj creases, thiab tus number case tuaj yeem tev tawm.
Siab:
Thaum tswj lub lamination kub kom zoo, lub siab tsim nyog yuav tsum tau siv. Qhov no yog vim qhov saum npoo ntawm daim ntawv nws tus kheej tsis tiaj tus. Tsuas yog nyob rau hauv siab tuaj yeem ua rau cov dej kub yaj nplaum ua kom ntub dej ntawm cov ntawv luam tawm los ntawm kev tshem tawm cua. Qhov no tso cai rau cov colloidal molecules diffuse thiab interlock nrog cov number case txheej thiab daim ntawv fibers, ua tiav adhesion zoo thiab tiav kev pab them nqi ntawm tag nrho cov saum npoo ntawm cov khoom luam tawm. Qhov tshwm sim yog glossy tsos, tsis muaj fogging, ib tug du bondline, tsis muaj creases, thiab zoo adhesion. Los ntawm qhov tsim nyog nce siab nyob rau hauv cov xwm txheej uas tsis yog-folding, lub thermoplastic curing muaj peev xwm ntawm cov nplaum kub yaj tuaj yeem siv tau los xyuas kom meej tias cov khoom laminated muaj zog tiv thaiv rau ntau lub cev tev thiab cuam tshuam lub zog (xws li indentation thiab bronzing) thaum lub sij hawm sib txuas kev muaj peev xwm. cov txheej txheem tom qab. Qhov no tau lees paub qhov zoo sib xws hauv cov qauv sab hauv thiab qhov chaw ntawm laminated prints.
Ceev:
Daim ntawv laminating yog ib qho kev sib xyaw ua ke hauv kev ua haujlwm zoo. Qhov nrawm ntawm kev txav mus los txiav txim siab lub sijhawm nyob ntawm daim ntawv-yas cov khoom sib xyaw ntawm cov khoom sib txuas ua haujlwm thaum lub sij hawm thermocompression bonding txheej txheem. Nws kuj txiav txim siab tus nqi nkag ntawm qhov kub thiab txias hauv cov txheej txheem tsim khoom ntawm cov ntaub ntawv-yas sib xyaw thiab cov txiaj ntsig tiag tiag. Thaum lub lamination kub thiab siab yog tas li, qhov kev hloov ceev yuav cuam tshuam rau cov nyhuv lamination. Vim tias qhov kub thiab txias txwv tsis pub dhau, cov nyhuv tsuas yog hloov pauv ntawm qhov kev taw qhia tsawg dua li cov nqi teev. Raws li qhov nrawm nrawm, cov nyhuv yuav txo qis, qhov kub siab yuav tsis muaj zog, thiab yog tias qhov kev khiav ceev dhau lawm, nws yuav ua rau lub zog adhesion tsis muaj zog, ua rau atomization. Yog tias nws qeeb dhau, nws tsis muaj txiaj ntsig thiab tuaj yeem ua rau bubbling. Yog li ntawd, khiav ceev ntawm lubpre-coated laminating zaj duab xistxiav txim lub sij hawm sib cog lus ntawm lubthermal laminating zaj duab xisthiab daim ntawv luam tawm.
Qhov tseeb qhov tseem ceeb ntawm qhov kub thiab txias, siab, thiab ceev txhua yam muaj qee qhov ntau. Nrhiav tus nqi zoo tshaj plaws hauv kev xyaum yog qhov tseem ceeb heev los xyuas kom meej cov nyhuv lamination ntawm covkub lamination zaj duab xisthiab tsim kom muaj kev haum xeeb rau cov txheej txheem tom ntej xws li kev khi npog thiab txha nraub qaum.
