Laminating zaj duab xisyog ib qho kev ua haujlwm siab -cov ntaub ntawv nyias nyias siv los tiv thaiv cov ntawv, cov ntaub ntawv luam tawm, rooj tog vaj huam sib luag, thiab lwm yam substrates. Los ntawm kev npog qhov chaw los ntawm cov txheej txheem thermal lossis txias lamination, nws tsis yog tsuas yog txhim kho qhov pom kev pom thiab kev paub txog kev paub tab tab sis kuj txhim kho kev ua haujlwm ntev, noo noo tsis kam, khawb tsis kam, thiab tiv thaiv - cov khoom staining.
Kev npaj kom zoo ua ntej lamination yog qhov tseem ceeb kom tsis txhob muaj teeb meem xws li bubbling, ntug curling, tsis zoo adhesion, los yog zaj duab xis deformation. Tsab ntawv xov xwm no yuav muab cov lus qhia ntxaws ntxaws txog dab tsi los xyuas txog cov khoom siv, khoom siv, substrates, ib puag ncig, thiab kev nyab xeeb ua ntej siv lamination zaj duab xis.
1. Paub meej hom thiab Specification ntawm Laminating Film
Xaiv cov khoom siv ua yeeb yaj kiab zoo yog thawj kauj ruam los xyuas kom meej siab - zoo lamination. PET zaj duab xis yog tus cwj pwm los ntawm lub zog siab, tawv, thiab ua haujlwm kub zoo heev, ua rau nws haum rau kev siv sijhawm ntev -. Nws qhov kev khiav hauj lwm kub tsis tu ncua yog li ntawm 80-100 degree, thiab nws muaj kev tiv thaiv- daj thiab UV- cov khoom tiv thaiv.
PVC zaj duab xis, ntawm qhov tod tes, yog hloov tau, tus nqi - zoo, thiab haum rau cov ntaub ntawv niaj hnub lamination lossis luv luv - siv sijhawm. Txawm li cas los xij, nws muaj qhov ua haujlwm qis dua thiab tuaj yeem daj lossis npuas thaum lub sijhawm.
Zaj duab xis thickness kuj yuav tsum tau ua tib zoo xaiv. Common thickness ranges los ntawm75-250 microns:
Nyias films (75-100 microns):Zoo tagnrho rau cov ntaub ntawv los yog cov ntaub ntawv luam tawm hnyav.
Medium{0}}thickness films (100–150 microns):Haum rau cov duab lossis cov ntaub ntawv tshaj tawm.
Thick films (150-250 microns):Haum rau cov rooj tog vaj huam sib luag lossis cov khoom siv.
Tsis tas li ntawd, paub meej tias cov zaj duab xis yog thermal lossis txias lamination. Thermal films xav tau cua sov los kaw, thaum cov yeeb yaj kiab txias tuaj yeem siv rau ntawm chav tsev kub. Kev nkag siab txog txoj kev lamination yog qhov tseem ceeb ua ntej siv.
2. Tshawb xyuas cov cuab yeej thiab cov cuab yeej
Lamination zoo heev nyob ntawm cov khoom siv. Rau cov yeeb yaj kiab thermal, lub laminator yuav tsum ncav cuag qhov kub thiab txias: 120-140℃rau PET thiab 90-110℃rau PVC. Kev teeb tsa siab sib npaug tseem ceeb; ntau dhau los yog me ntsis siab tuaj yeem ua rau bubbling lossis ntug curling.
Ua ntej ua haujlwm, ntxuav cov chais thiab lamination platform kom tshem tawm cov plua plav, cov ntawv khib nyiab, lossis cov nplaum seem. Preheat cov cuab yeej kom txog thaum qhov kub thiab txias stabilizes. Ua kom cov cua sov zoo ib yam thiab huv si yog qhov tseem ceeb rau kev ua tiav cov lamination du.
3. Tshawb xyuas qhov chaw ntawm substrates
Lub substrate nto ncaj qha cuam tshuam rau lamination zoo. Txawm hais tias nws yog ntawv, cov ntaub ntawv luam tawm, lossis cov rooj tog zaum, qhov chaw yuav tsum qhuav, huv si, thiab tiaj tus. Plua plav, roj, lossis dej noo tuaj yeem ua rau npuas, qhov chaw o, lossis ua rau tsis zoo.
Rau cov rooj tog vaj huam sib luag, paub meej tias cov cua sov tiv thaiv kom tsis txhob deformation lossis discoloration thaum lamination. Rau cov ntawv thiab cov ntaub ntawv luam tawm, tsis txhob folds, curls, thiab creases, vim tias cov khoom no tuaj yeem ua rau cov khoom tsis zoo.
4. Ua qhov kuaj lamination
Ua ntej puv - nplai lamination, ua ib qho kev sim me me ntawm lub ces kaum lossis qauv. Saib seb cov zaj duab xis adheres tusyees tsis muaj npuas, wrinkles, los yog ntug curling. Raws li qhov kev sim, koj tuaj yeem kho qhov kub, siab, thiab ceev ntawm lub laminator kom ntseeg tau tias cov txiaj ntsig tau zoo thaum siv tag nrho.
5. Xav txog tej yam xwm txheej ib puag ncig
Environmental yam tseem ceeb cuam tshuam rau lamination zoo. Cov av noo siab tuaj yeem ua rau npuas, thaum qhov kub qis yuav ua rau tsis zoo adhesion lossis ntug curling. Qhov zoo tshaj plaws, ua lamination nyob rau hauv ib puag ncig nrog kub ib ncig20-25 ° Cthiab av noo qis dua 60%. Xyuas kom muaj qhov cua zoo thiab txo cov plua plav thiab zoo li qub kom tswj tau qhov du, txawm tias zaj duab xis nto.
6. Kev ceev faj txog kev nyab xeeb
Kev tuav lub laminator muaj qhov kub thiab txias, yog li kev nyab xeeb yog qhov tseem ceeb. Tsis txhob sib cuag ncaj qha nrog cov cua kub thiab cov phaj kom tiv thaiv kev kub nyhiab. Hnav cov hnab looj tes tiv thaiv thiab tsom iav thaum tsim nyog, tshwj xeeb tshaj yog thaum tuav cov yeeb yaj kiab tuab lossis cov vaj huam sib luag loj. Khaws cov khaub ncaws thiab cov ntiv tes kom huv si ntawm cov chais thiab cov khoom txav kom ntseeg tau tias tus neeg tsav tsheb muaj kev nyab xeeb thiab kev ncaj ncees ntawm zaj duab xis.
7. Cov teeb meem tshwm sim thiab kev tiv thaiv
Bubbling:Feem ntau tshwm sim los ntawm qhov tsis sib xws ntawm qhov chaw substrate, plua plav, lossis dej noo.
Kev daws:Ntxuav lub substrate, tswj qhov kub thiab txias, thiab xyuas kom meej tias zaj duab xis - substrate compatibility.
Ntug Curling:Feem ntau vim qhov dav ntawm zaj duab xis yog nqaim dhau, lub tshuab ceev ceev, lossis cov menyuam tsis sib xws.
Kev daws:Xaiv qhov dav ntawm zaj duab xis tsim nyog, kho qhov nrawm, thiab xyuas kom muaj cua sov.
Adhesion tsis zoo:Ua los ntawm qhov kub thiab txias, tsis txaus siab, los yog incompatible zaj duab xis thiab substrate.
Kev daws:Kho cov cuab yeej teeb tsa raws li cov yeeb yaj kiab tuab thiab kuaj ntawm tus qauv.
Kev paub txog cov kev tiv thaiv no tuaj yeem txo qis lamination tsis ua haujlwm thiab txhim kho ob qho tib si kev ua haujlwm thiab cov khoom zoo.
8. Cov ntsiab lus thiab cov kev coj ua zoo tshaj plaws
Ua ntej siv laminating zaj duab xis, paub meej tias hom zaj duab xis thiab thickness, xyuas cov cuab yeej, ntxuav lub substrate nto, tswj ib puag ncig tej yam kev mob, thiab ua ib tug me me lamination. Ua raws li cov kauj ruam no ua kom muaj - lamination zoo, zam cov teeb meem tshwm sim, thiab ua kom muaj txiaj ntsig zoo tshaj plaws ntawm kev tiv thaiv, kev zoo nkauj, thiab kev ua haujlwm ntawm laminating zaj duab xis. Kev siv kom zoo tiv thaiv cov ntaub ntawv, cov ntaub ntawv luam tawm, thiab cov rooj tog zaum, muab kev tiv thaiv ntev ntev -.
