Cov txheej txheem laminating thiab cov txheej txheem glazing ob leeg yog nyob rau hauv qeb ntawm post-printing nto tiav ua tiav ntawm cov ntawv luam tawm.Cov haujlwm ntawm ob qho tib si zoo sib xws, thiab ob qho tib si tuaj yeem ua lub luag haujlwm hauv kev kho kom zoo nkauj thiab tiv thaiv qhov chaw ntawm cov ntawv luam tawm, tab sis muaj qhov sib txawv ntawm ob:
Nto xov
Nto xov yog ua kom tsim nyog rau ntawm qhov chaw ntawm cov ntawv luam tawm los txhim kho lub teeb ua haujlwm, dej tsis kam, tiv thaiv tshav kub, folding tsis kam, hnav tsis kam thiab tshuaj lom neeg ntawm cov ntawv luam tawm;nce qhov gloss thiab kev zoo nkauj ntawm cov ntawv luam tawm;thiab tiv thaiv cov ntawv luam tawm.Thiab kev ua haujlwm ntawm kev ua kom zoo nkauj ntawm cov ntawv luam tawm thiab nce tus nqi ntawm cov ntawv luam tawm.Cov txheej txheem kev hloov kho saum npoo rau cov ntawv luam tawm muaj xws li glazing, lamination, foiling, tuag-txiav, creasing lossis lwm yam ua.
01 lus
Laminationyog txheej txheem tom qab luam ntawv uas cov yas zaj duab xis coated nrog cov nplaum yog them rau saum npoo ntawm cov ntawv luam tawm.Tom qab cua sov thiab kev kho mob siab, cov ntawv luam tawm thiab cov yeeb yaj kiab yas tau zoo sib xyaw ua ke los ua cov khoom siv ntawv-yas sib xyaw.Cov txheej txheem lamination belongs rau cov txheej txheem ntawv-yas sib xyaw hauv cov txheej txheem sib xyaw thiab yog cov khoom sib xyaw qhuav.
Glazing yog txheej txheem uas siv cov xim tsis muaj xim pob tshab (lossis txau los yog luam tawm) rau ntawm qhov chaw luam tawm.Tom qab leveling thiab ziab (calendering), ib txheej nyias thiab txawm pob tshab ci yog tsim rau saum npoo ntawm cov ntawv luam tawm.Cov txheej txheem yog txheej txheej (feem ntau hu ua Cov txheej txheem ntawm kev siv cov kua roj vanish (xws li zaj duab xis-forming resin, hnyav thiab additives) rau saum npoo ntawm cov ntawv luam tawm rau qib thiab ziab.
02 Muaj nuj nqi thiab lub ntsiab lus
Tom qab qhov saum npoo ntawm cov ntawv luam tawm yog npog nrog txheej txheej ntawm cov yas zaj duab xis (txheej txheem) los yog coated nrog ib txheej ntawm cov xim glazing (glazing), cov ntaub ntawv luam tawm tuaj yeem ua kom muaj kev ua haujlwm ntawm kev sib txhuam, dej-pov thawj, waterproof thiab anti-fouling, thiab lwm yam., uas tsis tsuas yog tiv thaiv cov ntawv luam tawm, tab sis kuj tiv thaiv cov ntawv luam tawm.Nthuav nws cov kev pab cuam lub neej, nws kuj txhim kho qhov ci ntsa iab ntawm qhov chaw ntawm cov ntawv luam tawm, txhim kho nws cov txiaj ntsig zoo nkauj, ua rau cov ntawv luam tawm thiab cov ntawv ci xim, thiab muaj qhov pom kev zoo, yog li txhim kho cov khoom zoo thiab ua kom cov khoom zoo. tus nqi ntxiv.Piv txwv li, phau ntawv npog lamination, nto glazing ntawm cosmetic ntim thawv, thiab lwm yam.
Yog li ntawd, laminating thiab glazing yog ib qho ntawm cov txheej txheem tseem ceeb rau kev luam ntawv tom qab ua tiav ntawm cov ntawv luam tawm.Lawv tuaj yeem tsis tsuas yog "ua kom ci" ntawm qhov chaw luam tawm thiab nyiam cov neeg siv khoom txaus siab, tab sis kuj tseem tiv thaiv cov ntawv luam tawm thiab txhim kho nws cov kev ua tau zoo.Tam sim no lawv tau siv dav.Nws yog qhov tsim nyog rau kev kho kom zoo nkauj saum npoo ntawm cov phau ntawv, ntu ntu, duab albums, ntau yam ntaub ntawv, cov ntawv tshaj tawm thiab kho kom zoo nkauj ntawm ntau yam khoom ntim khoom.
03 Cov txheej txheem sib txawv
Zaj duab xis txheej txheej ua yeeb yaj kiab tuaj yeem faib ua cov duab ua ntej tam sim no thiab cov yeeb yaj kiab ua ntej ua ntej siv cov ntaub ntawv sib txawv thiab cov khoom siv sib txawv.
1) Covtxheej zaj duab xis txheej txheem ua ntej siv cov txheej txheem txheej txheej txheej txheej kom sib npaug ntawm cov nplaum rau ntawm qhov chaw ntawm cov yas zaj duab xis.Tom qab dhau los ntawm lub tshuab ziab khaub ncaws, cov kuab tshuaj hauv cov nplaum yog evaporated, thiab tom qab ntawd cov ntawv luam tawm raug rub mus rau lub tshuab kub nias lamination.Ntawm lub tshuab, lubyas zaj duab xisthiab cov ntawv luam tawm raug nias ua ke kom ua tiav cov lamination thiab rov ua dua, thiab tom qab ntawd muab khaws cia rau shaping thiab slitting.Txoj kev no yog tam sim no siv nyob rau hauv Suav teb.Los ntawm qhov kev xav ntawm cov khoom siv nplaum uas siv rau hauv zaj duab xis txheej, nws tuaj yeem muab faib ua cov nplaum nplaum nplaum nplaum thiab cov nplaum nplaum dej.
2) Pre-txheej zaj duab xis Cov txheej txheem ua ntej txheej txheej yog rau cov neeg tsim khoom ua ntej kom muaj nuj nqis thiab sib npaug siv cov nplaum rau ntawm cov yeeb yaj kiab yas, qhuav, rov qab, thiab ntim lawv rau hauv cov khoom muag, thiab tom qab ntawd cov tuam txhab ua haujlwm siv cov nplaum-dawb txheej rau lawv.Kub nias yog ua rau ntawm cov khoom siv laminating ntawm lub cuab yeej kom tiav cov txheej txheem lamination ntawm cov ntawv luam tawm.Cov txheej txheem ua ntej txheej zaj duab xis ua kom yooj yim rau txheej txheej txheej txheej vim tias cov cuab yeej txheej tsis xav tau cov nplaum cua sov thiab ziab, thiab yooj yim heev rau kev khiav lag luam.Nyob rau tib lub sijhawm, tsis muaj qhov hnyav volatilization thiab tsis muaj kuab paug ib puag ncig, uas txhim kho kev ua haujlwm;tseem ceeb tshaj, nws Qhov tshwm sim ntawm txheej tsis zoo xws li npuas thiab delamination yog zam kiag li.Lub pob tshab ntawm cov khoom coated yog siab heev.Piv nrog rau cov txheej txheem txheej txheem txheej txheem, nws muaj kev thov dav dua.
1) Solvent-based glazing Solvent-based glazing yog hais txog cov txheej txheem glazing uas siv benzene, esters thiab cawv ua cov kuab tshuaj thiab cov thermoplastic resin ua zaj duab xis-tsim resin.Thaum lub sij hawm glazing txheej txheem, cov kuab tshuaj evaporates thiab cov resin polymerizes los yog Cross-linking cov tshuaj tiv thaiv ua ib zaj duab xis.Nws yog tus cwj pwm los ntawm cov cuab yeej siv me me thiab tus nqi qis, tab sis cov kuab tshuaj volatilization thiab residue ntawm cov ntawv luam tawm yuav ua rau muaj kuab paug ib puag ncig thiab ua rau muaj kev phom sij rau tib neeg lub cev.
2) Dej-raws li glazing Dej-raws li glazing yog ib txoj kev glazing uas siv cov dej-soluble resin los yog ntau hom dej-dispersed resins ua zaj duab xis-tsim tshuaj.Dej-raws li glazing xim siv dej ua cov kuab tshuaj, thiab tsis muaj cov organic solvent volatile teeb meem thaum txheej txheej thiab ziab.Cov yam ntxwv yog tias cov txheej txheem glazing tsis muaj ntxhiab tsw ntxhiab, tsis muaj kuab paug rau ib puag ncig, thiab tsis muaj teeb meem rau tib neeg lub cev.Nws yog dav siv nyob rau hauv ntim ntawm luam yeeb, tshuaj, zaub mov, tshuaj pleev ib ce thiab lwm yam khoom.
3) UV glazing UV glazing yog ultraviolet hluav taws xob qhuav glazing.Nws siv cov hluav taws xob ultraviolet rau irradiate cov roj glazing kom sai sai ua rau cov tshuaj tiv thaiv photochemical ntawm cov roj glazing los tsim cov txheej ci ci nrog cov qauv tshuaj network ntawm cov khoom luam tawm.Cov txheej txheem glazing curing yog tib yam li cov txheej txheem ziab ntawm UV number case.Nws yog tus cwj pwm los ntawm gloss zoo, muaj zog tiv thaiv tshav kub thiab hnav tsis kam, ziab sai, kev nyab xeeb thiab kev tiv thaiv ib puag ncig.Nws muaj kev lag luam loj hlob zeem muag.Zoo li dej-raws li glazing, feem ntau yog siv rau hauv tshuaj, khoom noj khoom haus, thiab lwm yam khoom ntim rau hauv lub tshav pob.
