Lamination delamination yog ib qho teeb meem zoo hauv cov txheej txheem lamination. Nws yog tus cwj pwm los ntawm kev ua tsis zoo ntawm cov yeeb yaj kiab nyias thiab cov substrates, xws li ntawv, cardboard lossis lwm yam ntaub ntawv, ua rau ib nrab lossis tag nrho sib cais, ntug nqa lossis blistering. Txheej tsis tsuas yog cuam tshuam rau cov khoom zoo nkaus li, tab sis kuj txo qhov hnav -ua haujlwm, ntub- ua haujlwm thiab kev pabcuam lub neej ntawm lub ntim thiab, nyob rau hauv cov xwm txheej hnyav, ua rau cov khoom seem ntawm tag nrho cov khoom tsim tawm. Muaj ntau qhov laj thawj rau decolletage, suav nrog cov khoom siv, cov khoom siv tsis zoo, cov txheej txheem tswj thiab ib puag ncig tsim khoom. Tsuas yog los ntawm kev txheeb xyuas cov laj thawj kom raug thiab siv cov kev ntsuas tsim nyog tuaj yeem txhim kho cov txheej txheem zoo thiab kev tsim khoom zoo. Cov ntu hauv qab no muab cov ncauj lus kom ntxaws txog rau qhov tseem ceeb.
1.Kev xaiv tsis raug lossis siv cov nplaum nplaum
Adhesives yog cov ntaub ntawv tseem ceeb los ua kom muaj kev sib raug zoo ntawm cov yeeb yaj kiab thiab cov substrate thiab tuaj yeem yooj yim ua rau txheej txheej yog tias tsis xaiv lossis siv kom raug.
Hom Adhesive tsis sib haum
Cov ntaub ntawv lamination sib txawv (xws li BOPP, PET lossis PVC zaj duab xis) thiab hom ntawv muaj qhov sib txawv rau kev ua haujlwm nplaum. Qhov sib txawv ntawm qhov sib txawv ntawm cov nplaum thiab cov khoom yuav cuam tshuam rau kev sib raug zoo thiab ua rau lub lamination yooj yim cais.
Adhesive Quantity Control tsis raug
Kev siv tsis zoo ntawm cov nplaum tuaj yeem ua rau qhov chaw sib txuas tsis txaus thiab txo qhov adhesion, thaum siv cov nplaum ntau dhau tuaj yeem ua rau qeeb ziab, kev sib sau hauv zos lossis cov npuas cua, tag nrho cov no tuaj yeem cuam tshuam tsis zoo rau lamination zoo. Yog li ntawd, tus nqi ntawm cov nplaum yuav tsum tau kho raws li cov khoom thickness thiab cov txheej txheem yuav tsum tau ua.
2.Kev tswj qhov kub tsis zoo
Nyob rau hauv cov txheej txheem lamination, cua sov kub ncaj qha cuam tshuam rau kev ua kom thiab kev sib txuas zoo ntawm cov nplaum.
Kub Tsawg heev
Yog tias cov cua kub tsis txaus, cov nplaum yuav tsis tuaj yeem yaj tag lossis ua kom tsis muaj zog, ua rau nws tsis tuaj yeem tsim kev sib raug zoo ntawm cov yeeb yaj kiab thiab cov ntawv, ua rau muaj teeb meem xws li hauv zos delamination lossis ntug sib cais.
Kub dhau heev lawm
Qhov kub thiab txias dhau lawm, yuav ua rau qhov kev ua tau zoo ntawm cov nplaum, ua rau cov yeeb yaj kiab shrinkage lossis deformation, lossis tseem ua rau daim ntawv lub ntsej muag puas, yog li ua rau lub zog nplaum tsis muaj zog. Yog li ntawd, qhov ntsuas kub yuav tsum tau teeb tsa raws li hom tshwj xeeb ntawm cov nplaum thiab cov khoom siv laminated siv.
3.Tsis tsim nyog siab thiab ceev steering tsis
Lamination siab thiab kev ua haujlwm ceev kuj yog cov txheej txheem tseem ceeb uas cuam tshuam rau kev sib raug zoo. Tsis txaus lamination siab
Yog hais tias lub siab ntawm cov menyuam siv lub zog me me dhau, cov yeeb yaj kiab thiab ntawv tsis tuaj yeem ua tiav daim ntawv cog lus, cov ntawv cog lus tsis tuaj yeem sib npaug sib npaug, ua rau muaj qhov sib txawv, txo cov ntawv cog lus.
Kev tsim tawm sai heev
Yog tias lub cuab yeej khiav nrawm dhau, lub sijhawm cua sov thiab compression ntawm cov nplaum txheej yuav luv. Yog li ntawd, ua ntej cov nplaum nkag mus rau lub caij txias, nws tuaj yeem txhim kho nws cov khoom sib txuas, yog li ua rau muaj kev pheej hmoo ntawm decolletage.
4. Cov khoom siv laminated zoo
Qhov zoo ntawm cov ntaub ntawv lamination nws tus kheej kuj tseem yuav cuam tshuam rau qhov kawg kev sib raug zoo.
Kev kho tsis zoo ntawm cov yeeb yaj kiab nto
Yog tias cov yeeb yaj kiab tsis raug kho nrog corona lossis tsis muaj qhov nro txaus, qhov adhesion raug cuam tshuam, ua rau muaj kev sib raug zoo ntawm cov yeeb yaj kiab thiab cov substrate.
Abnormal Paper Moisture Content
Cov ntaub ntawv noo noo siab dhau los yog qis dhau yuav cuam tshuam rau lamination zoo. Cov dej noo ntau dhau tuaj yeem ua rau evaporation thiab npuas tsim, thaum tsis txaus noo noo tuaj yeem deform daim ntawv, cuam tshuam adhesion. Yog li, cov ntaub ntawv uas ua raws li cov txheej txheem tshwj xeeb yuav tsum tau siv thiab khaws cia kom raug.
5. Cov khoom siv tsis zoo
Cov khoom siv tsis ruaj khov ua haujlwm kuj tuaj yeem ua rau txo qis hauv lamination zoo.
Hnav cov cots los yog Pressure Rollers
Adhesive los yog siab rollers nto abrasion, khawb los yog tsub zuj zuj ntawm impurities yuav ua rau uneven tis ntawm siab, cuam tshuam lub uniformity ntawm cov nplaum txheej, tej zaum yuav ua rau lub zos delamination.
Kev tswj qhov kub thiab txias lossis Tsav System ua haujlwm tsis zoo
Kev tswj qhov kub tsis raug, tawm ntawm synchronizing cov menyuam ceev, lossis tsis ruaj khov kev thauj mus los tuaj yeem ua rau cov cua sov tsis sib xws thiab siab thaum txheej txheej txheej txheej txheej txheej, yog li txo cov ntawv cog lus zoo.
6. Ib puag ncig kev tsim khoom tsis txaus thiab kev tswj cov txheej txheem
Kev tsim khoom ib puag ncig thiab kev tswj xyuas kev ua haujlwm kuj cuam tshuam rau cov txiaj ntsig lamination.
Unsuitable Environmental Temperature thiab humidity
Cov av noo siab lossis kub hloov pauv ntawm lub rooj cob qhia ntau lawm yuav muaj qhov cuam tshuam tsis zoo rau kev kho cov nplaum thiab cov ntsiab lus noo ntawm daim ntawv, ua rau muaj peev xwm decolletage.
Tsis ua raws li cov qauv kev ua haujlwm
Kev ncua ntawm kev kho cov cuab yeej tsis ua haujlwm, tsis ua tiav cov txheej txheem kev teeb tsa tom qab hloov cov khoom siv, lossis kev saib xyuas cov cuab yeej tsis txaus tuaj yeem ua rau tsis zoo lamination. Yog li ntawd, kev tswj cov txheej txheem muaj zog thiab cov khoom siv tu vaj tse yuav tsum nyob hauv qhov chaw kom ntseeg tau tias cov txheej txheem tsim khoom raug tswj. Cov ntsiab lus
Lamination delamination feem ntau yog tshwm sim los ntawm kev sib xyaw ua ke, suav nrog kev xaiv cov nplaum nplaum, kev tswj qhov kub thiab txias, qhov chaw siab thiab ceev, qhov zoo ntawm cov ntaub ntawv lamination, cov khoom siv thiab qhov chaw tsim khoom. Hauv kev tsim khoom tiag tiag, peb yuav tsum xaiv cov nplaum tsim nyog raws li cov khoom siv thiab cov yam ntxwv ntawm cov khoom, txhim kho cov txheej txheem tsis zoo, tswj cov khoom siv hauv kev ua haujlwm zoo, nruj me ntsis tswj cov khoom siv raw thiab ib puag ncig ntau lawm. Los ntawm cov txheej txheem kev ua haujlwm thiab kev saib xyuas kev tshawb fawb, txheej txheej tuaj yeem txo qis, thiab cov khoom lag luam zoo tuaj yeem txhim kho.
Cov lus nug nquag
Q1: Dab tsi yog qhov laj thawj feem ntau rau lamination delamination?
A: Cov laj thawj feem ntau suav nrog kev xaiv cov nplaum tsis zoo, tsis txaus cua sov, tsis txaus lamination siab, kev kho cov yeeb yaj kiab tsis zoo, cov khoom siv ua haujlwm tsis zoo, thiab lwm yam, xav tau kev tshuaj xyuas zoo raws li kev tsim khoom tshwj xeeb.
Q2: Qhov sov dua lub laminate, qhov zoo dua?
A: Qhov kub qis dhau tuaj yeem cuam tshuam qhov ua kom cov nplaum nplaum, thiab qhov kub siab dhau tuaj yeem ua rau cov duab deformation, nplaum degradation lossis ntawv puas. Qhov kub thiab txias yuav tsum tau teem kom tsim nyog raws li cov khoom ntawm cov khoom thiab cov nplaum.
Q3: Yuav ua li cas txo cov teeb meem txheej?
A: Xaiv cov nplaum nplaum thiab cov laminates kom tswj tau qhov kub thiab txias, siab thiab ceev kom tswj cov khoom huv si thiab ua haujlwm zoo. Tsis tas li ntawd, kev tswj qhov kub thiab av noo nyob rau hauv lub rhiav pab txhim kho cov txheej txheem stability.
Q4: Ntev npaum li cas tom qab lamination koj tuaj yeem ua raws li?
A: Lub sijhawm kho nws txawv raws li cov nplaum siv. Feem ntau, nws raug nquahu kom tos kom txog thaum cov nplaum txheej tau kho kom tiav ua ntej tuag - txiav, creasing, kub stamping thiab lwm yam kev ua haujlwm kom txo qis kev pheej hmoo ntawm decolletage thiab xyuas kom cov khoom zoo.
