Adhesive Lamination txheej txheem yog dav siv hauv ntim, cov ntaub ntawv sib xyaw, thiab kev tsim khoom lag luam. Nws khi ob lossis ntau txheej ntawm cov ntaub ntawv ua ke siv cov nplaum los txhim kho lub zog, durability, thiab zoo li. Kev nkag siab txog cov txheej txheem no yog qhov tseem ceeb rau cov engineers, R & D cov neeg ua haujlwm, thiab cov tuam txhab tsim khoom kom ntseeg tau cov khoom zoo.
Cov txheej txheem feem ntau yog siv ib qhopolyurethane -raws li nplaummus rau hauv lub substrate (xws li yas zaj duab xis, ntawv, los yog txhuas ntawv ci), ziab tawm ntawm cov kuab tshuaj, laminating nyob rau hauv tshav kub thiab siab, thiab tom qab ntawd mus rau ib tug curing txheej txheem kom ua tau zoo daim ntawv cog lus lub zog. Nws yog ib qho tseem ceeb tshwj xeeb hauv kev tsim cov khoom lag luam siab -kev ua tau zoo ntawm kev ntim khoom noj, tshuaj, thiab cov khoom siv.
Nrog rau kev tswj hwm ib puag ncig, cov kuab tshuaj-dawb polyurethane adhesives, dej-raws li systems, thiab kub-melt adhesives yog maj mam hloov cov tshuaj hnyav-raws li formulations los txo VOC emissions thiab txhim kho sustainability.
Dab tsi yog Adhesive Lamination Process
Adhesive lamination yog txheej txheem uas txuas ob lossis ntau cov ntaub ntawv (xws li zaj duab xis, ntawv, ntawv txhuas, lossis ntaub) ua ke siv cov nplaum. Tsis zoo li extrusion lamination, nws tsis tas yuav melting cov ntaub ntawv, tab sis es tsis txhob cia siab rau cov nplaum los tsim ib daim ntawv cog lus muaj zog. Cov txheej txheem no feem ntau yog siv rau hauv kev ntim khoom yooj yim, thiab cov khoom sib xyaw ua ke.
Cov nplaum (cov kuab tshuaj-raws li, hnyav-dawb, lossis dej-raws li) yog siv rau hauv ib lub substrate, tom qab ntawd laminated nrog lwm qhov hauv qab tswj qhov kub thiab txias. Tom qab ziab thiab kho, ob txheej txheej ua kom muaj zog thiab ruaj khov sib xyaw.
Hom Adhesives siv hauv Lamination
Adhesive lamination cia siab rau kev xaiv cov nplaum tsim nyog, uas tsis tsuas yog txiav txim siab lub zog ntawm kev sib txuas, tab sis kuj tseem cuam tshuam rau tag nrho cov kev ua tau zoo ntawm cov qauv sib xyaw zaum kawg. Ntau hom adhesives yog tsim los ua kom tau raws li cov kev xav tau tshwj xeeb xws li kev nyab xeeb ntawm cov khoom noj, kev ua kom yooj yim, ua kom sov, thiab tshuaj lom neeg ruaj khov. Feem ntau, laminating adhesives poob rau hauv peb pawg tseem ceeb: cov kuab tshuaj-raws li, cov kuab tshuaj-dawb, thiab dej-raws li, txhua tus muaj cov yam ntxwv sib txawv thiab kev siv zoo tagnrho.
• Solvent-raws li Adhesive
Feem ntau cov tsoos thiab dav siv hom, paub txog nws cov kev sib txuas zoo zog thiab kub kub ua hauj. Nws yog qhov tshwj xeeb tshaj yog tsim rau siab -kev ua tau zoo ntawm cov ntawv ntim khoom, xws li cov hnab ntim khoom thiab cov khoom siv ua yeeb yaj kiab metallized.
Tau txais txiaj ntsig sai vim nws eco-tus phooj ywg thiab lub zog-cov khoom siv tau zoo. Hom no tshem tawm qhov xav tau ntawm cov kuab tshuaj evaporation, txo qis VOC emissions thiab lub zog noj, thaum muab kev nyab xeeb thiab huv si ntau lawm - zoo tagnrho rau cov niaj hnub siab - ceev laminating kab .
• Dej-raws li Adhesive
Feem ntau siv nyob rau hauv qis - tsw, ib puag ncig nco ntsoov ntim. Thaum nws cov cua sov thiab tshuaj tiv thaiv qis dua, nws ua tau zoo hauv daim ntawv - rau - zaj duab xis lossis ntawv - mus rau - ntawv lamination rau cov zaub mov qhuav thiab ntim khoom noj txom ncauj .
Kauj Ruam -los ntawm - Txheej Txheem Lamination
Adhesive lamination feem ntau ua raws li cov kauj ruam tseem ceeb no:
Kev Npaj Nto
Ntxuav thiab qhuav cov substrate kom tshem tawm cov plua plav, roj, lossis dej noo. Qee cov ntaub ntawv yuav xav tau kev kho mob corona lossis ntshav ntshav los txhim kho adhesion.
Daim ntawv thov Adhesive
Siv cov nplaum sib npaug rau ib lossis ob qho tib si substrates siv cov txheej txheem xws li yob txheej, gravure txheej, lossis txau.
Qhuav / Curing
Tshem tawm cov kuab tshuaj los yog pib kho ib nrab, nyob ntawm seb hom nplaum (xws li, hnyav-raws li, dej-raws li, lossis hnyav-dawb).
Lamination / Bonding
Bond cov ntaub ntawv ua ke nyob rau hauv kev tswj lub siab, kub, thiab ceev siv lub laminator.
Txias
Cia lub laminated qauv kom txias, stabilizing daim ntawv nplaum.
Kev tshuaj xyuas
Tshawb xyuas qhov tsis xws luag xws li npuas, wrinkles, los yog adhesion tsis zoo los xyuas kom meej cov khoom zoo.
Tej teeb meem & kev daws teeb meem
Adhesive lamination tseem tuaj yeem ntsib teeb meem cuam tshuam rau cov khoom lag luam thiab kev ua haujlwm zoo, txawm tias muaj cov cuab yeej siv siab heev thiab siab -cov nplaum nplaum zoo. Feem ntau cov teeb meem xws li adhesion tsis zoo, npuas los yog tunneling, kho tsis tiav, delamination, thiab txheej tsis sib xws. Cov no feem ntau tshwm sim los ntawm qhov sib xyaw tsis raug, kev kho tsis txaus, lossis kev kho deg tsis txaus.
Yuav kom tswj tau qhov zoo ib yam, cov tuam txhab lag luam yuav tsum txheeb xyuas cov hauv paus hauv paus thiab ua kom sai. Piv txwv li, kev kho cov txheej ceev thiab cov xovxwm cov menyuam lub siab txhim kho kev sib raug zoo thiab zoo li qub, thaum tswj qhov kub thiab av noo kom ruaj khov kho. Kev xaiv cov nplaum nplaum, qhov sib xyaw kom raug, thiab cov txheej txheem ua kom zoo dua qub yog qhov tseem ceeb rau kev sib koom ua ke thiab ntev - lub sij hawm durability.
Thaum kawg, kev lamination ua tau zoo tsis yog nyob ntawm txoj cai nplaum, tab sis thaum kawg - rau -kev tswj cov txheej txheem - los ntawm kev npaj cov khoom thiab txheej txheej rau kev kho thiab winding. Kev daws teeb meem sai sai txo cov khoom pov tseg, txhawb kev tsim tawm, thiab ua kom muaj kev xa khoom zoo ib yam ntawm - ntim ua tau zoo.
Adhesive lamination yog ntau yam thiab dav siv cov txheej txheem tsim khoom niaj hnub no. Kev nkag siab txog hom nplaum, cov txheej txheem txheej txheem, cov khoom siv, thiab cov teeb meem tshwm sim ua rau cov tuam txhab tsim khoom muaj txiaj ntsig zoo - cov khoom laminated zoo. Los ntawm kev xaiv cov ntaub ntawv tsim nyog thiab ua raws li cov txheej txheem raug, cov tuam txhab tuaj yeem ua tiav qhov sib npaug ntawm tus nqi thiab kev ua haujlwm ntawm cov khoom.
