Ntau cov chaw luam ntawv thiab cov neeg yuav khoom feem ntau ntsib teeb meem xws li bubbling, delamination, whitening, silver spots, thiab curling thaum siv tshav kub- laminating zaj duab xis. Cov teeb meem no feem ntau cuam tshuam rau qhov chaw kub tsis raug. Yog li ntawd, kev nkag siab txog "kev ntsuas kub kom raug rau cov cua sov- laminating zaj duab xis" tsis yog cov lus nug tseem ceeb xwb tab sis kuj yog ib qho tseem ceeb rau kev ua kom ruaj khov thiab txo cov nqi seem.
Feem ntau, kev khiav hauj lwm kub rautshav kub- laminating zaj duab xisFeem ntau ntawm 85℃thiab 115 degree. Txawm li cas los xij, qhov tshwj xeeb kub tsis yog tus nqi ruaj khov tab sis yuav tsum tau hloov kho raws li cov yam ntxwv xws li hom zaj duab xis, daim ntawv tuab, txoj kev luam ntawv, thiab cov khoom siv ceev. Yog tias qhov kub thiab txias qis dhau, cov nplaum txheej tsis tuaj yeem yaj txaus; yog tias qhov kub thiab txias dhau lawm, nws yuav ua rau daim ntawv deformation lossis zaj duab xis shrinkage. Yog li ntawd, qhov tseem ceeb ntawm qhov kub thiab txias yog "kev sib txuam," tsis yog tsuas yog nrhiav qhov kub thiab txias.
Pom zoo qhov kub thiab txias rau ntau hom ntawm laminating zaj duab xis
Ntau hom laminating zaj duab xis muaj qhov sib txawv ntawm qhov yuav tsum tau muaj qhov kub thiab txias vim qhov sib txawv ntawm cov nplaum nplaum thiab cov qauv saum npoo.
1. BOPP Pre-coated Thermal Laminating Film
BOPP thermal laminating zaj duab xis yog tam sim no cov khoom siv dav tshaj plaws, nrog kev pom zoo kub ntau ntawm 85℃-105 degree. Tsis pub dhau qhov no, EVA nplaum txheej tuaj yeem yaj tag nrho thiab tsim kev ruaj ntseg nrog daim ntawv nto, haum rau feem ntau cov khoom lag luam offset.
2. Digital Printing Lamination
Cov tshuab luam ntawv digital muaj ntau dua toner npog thiab cov ntawv smoother, ua rau kev sib txuas kuj nyuaj dua. Yog li, qhov pom zoo kub yog feem ntau ntawm 95℃-115 degree. Kev kub siab dua pab cov nplaum txheej nkag mus rau txheej toner zoo dua, txhim kho adhesion thiab txo cov nyiaj pom.
3. Matte Zaj duab xis
Qhov pom zoo kub rau matte zaj duab xis yog feem ntau 90℃-110 degree. Vim yog cov qauv tshwj xeeb ntawm lub ntsej muag matte, cov cua sov txaus yuav tsum tau ua kom muaj kev sib txuam ntawm cov nplaum nplaum thaum tsis txhob ntog fogging lossis tsis sib xws.
4. Mos kov zaj duab xis
Vim nws qhov tshwj xeeb txheej txheej, qhov kub ntawm qhov muag kov zaj duab xis feem ntau pom zoo kom tswj tau ntawm 100℃thiab 115 degree. Qhov kub qis dhau tuaj yeem ua rau tsis zoo adhesion, thaum kub dhau heev yuav ua rau nws cov nyhuv tactile du; Yog li ntawd, kev tswj qhov kub thiab txias yog qhov tseem ceeb heev.
Yam tseem ceeb cuam tshuam rau laminating kub
Daim Ntawv Thickness: Cov ntawv tuab absorbs cua sov ntau dua, yuav tsum tau kub siab dua lossis kub dua - lub sijhawm nias kom ua tiav cov nplaum nplaum. Cov ntawv nyias nyias tuaj yeem ua rau curling lossis deformation yog tias qhov kub thiab txias dhau, yog li yuav tsum tau ua tib zoo hloov kho.
Txoj Kev Luam Ntawv: Offset luam ntawv nto yog tsim nyog rau kev sib txuas, thaum luam ntawv digital, vim nws cov txheej txheem toner tuab, feem ntau yuav tsum muaj qhov kub thiab txias dua los xyuas kom meej qhov zoo adhesion. Siv cov txheej txheem offset luam ntawv qhov kub thiab txias nrog cov yeeb yaj kiab digital feem ntau ua rau delamination lossis nyiaj pob.
Laminating Tshuab Ceev: Lub tshuab nrawm dua txhais tau tias cov zaj duab xis luv dua- lub sij hawm sib cuag ntawm daim ntawv, feem ntau yuav tsum tau kub siab dua kom ua tiav cov nplaum nplaum. Hloov pauv, lub tshuab qeeb qeeb tso cai rau qhov kub thiab txias kom tsis txhob overheating.
Ambient Temperature thiab Humidity: Nyob rau hauv qhov chaw txias, lub tshuab ua ntej lub sij hawm ntev dua cov nplaum nplaum, uas yuav tsum tau kub dua me ntsis. Cov av noo ntau dua ua rau cov ntawv ya raws cov ntsiab lus, tseem cuam tshuam rau kev sib txuas ua haujlwm.
Cov teeb meem dab tsi tshwm sim thaum qhov kub thiab txias qis dhau?
Thaum qhov kub thiab txias qis dua qhov melting point ntawm cov nplaum txheej, cov nplaum tsis tuaj yeem ua kom tiav. Cov teeb meem tshwm sim muaj xws li:
Nto blistering
Ntug delamination
Tsis zoo adhesion
Cov pob nyiaj tau tshwm sim hauv cov luam ntawv digital
Lub hauv paus ua rau ntawm cov teeb meem no yog tias cov nplaum txheej tsis yog tag nrho yaj thiab tsis tuaj yeem nkag mus rau hauv cov ntawv fiber ntau.
Dab tsi txaus ntshai cuam tshuam nrog kev kub siab heev?
Daim ntawv tuaj yeem deform lossis wrinkle ntawm qhov kub thiab txias, thiab laminated nto yuav shrink, txawm cuam tshuam gloss thiab smoothness. Rau cov yeeb yaj kiab tshwj xeeb, xws li tactile lossis matte films, qhov kub thiab txias tuaj yeem ua rau lawv cov qauv nto, txo lawv cov kev ntxhib los mos.
Tsis tas li ntawd, qhov kub thiab txias ntau dhau yuav ua rau cov nplaum nplaum dhau, cuam tshuam rau cov khoom tiav cov tsos thiab ua rau muaj kev nyuaj ntawm kev ua haujlwm tom ntej.
Yuav ua li cas kom raug kuaj thiab kho lub laminating kub?
Txoj kev hloov kho kev tshawb fawb yuav tsum pib nrog tus nqi qis tshaj plaws nyob rau hauv qhov ntsuas kub tau pom zoo, ua qhov me me - batch sim ntau lawm sim. Tom qab soj ntsuam qhov adhesion, kho qhov kub thiab txias maj mam nce ntawm kwv yees li 5℃kom txog thaum pom qhov adhesion tiav. Thaum kuaj, ib txhij xyuas qhov chaw nruab nrab thiab ntug ntawm daim ntawv kom ntseeg tau tias muaj kev sib txuam thiab ruaj khov tag nrho adhesion.
Tsis tas li ntawd, kev hloov kho yuav tsum tau ua ua ke nrog lub tshuab ceev, tsis yog hloov qhov ntsuas kub ib leeg. Cov khoom lag luam ruaj khov tau tshwm sim los ntawm qhov sib npaug ntawm qhov kub, siab, thiab ceev.
Qhov tseem ceeb ntawm kev xaiv ib tug ruaj khov laminating zaj duab xis
High- zoo laminating zaj duab xis muaj qhov zoo ntawm cov nplaum sib xws thiab txheej txheej ruaj khov, ua kom tswj tau qhov kub thiab txias yooj yim dua. Yog tias cov nplaum txheej ntawm zaj duab xis nws tus kheej tsis sib npaug los yog qhov tuab tsis ruaj khov, qhov kev hloov pauv zoo yuav tshwm sim txawm tias qhov tseeb qhov kub thiab txias. Yog li ntawd, xaiv tus neeg xa khoom nrog cov txheej txheem txheej txheem paub tab thiab cov txheej txheem tsim khoom ruaj khov yog qhov tseem ceeb rau kev tsim khoom ntev -.
Qhov kub thiab txias rau cov cua sov- laminating zaj duab xis feem ntau yog nyob nruab nrab ntawm 85℃thiab 115 degree, tab sis qhov tseem ceeb tiag tiag yog nyob rau hauv kev kho kom haum raws li hom zaj duab xis, ntawv thickness, luam ntawv txoj kev, thiab cov cuab yeej ceev. Qhov kub qis dhau tuaj yeem ua rau tsis zoo adhesion thiab bubbling, thaum kub dhau heev yuav ua rau daim ntawv deformation thiab zaj duab xis puas.
