Aluminium foil daim ntawv nws tus kheej-nplaum cov ntaub ntawv saum npoo yog cov khoom sib xyaw ntawm cov ntawv thiab txhuas ntawv ci, zoo li hlau thiab yas nto, txoj kev ziab ntawm tus number case tsuas yog oxidation, polymerization, volatilization, condensation, curing, thiab tsis muaj txheej txheem permeation. Yog li ntawd, tus number case tsis ziab thiab adhesion yog ob qho teeb meem tseem ceeb thaum luam ntawv. Cov ntawv ci txhuas feem ntau muaj cov txheej txheej saum npoo, tsis muaj teeb meem ntawm tus number case firmness, thiab kev daws teeb meem tsim nyog rau qhov teeb meem ntawm tus number case drying yog tus yuam sij rau txhuas lub thawv ntawv luam ntawv.
Raws li cov yam ntxwv ntawm aluminium boxing, cov qauv tsim qauv ntawm cov duab luam tawm yog:
Ua ntej, cov lus yooj yooj yim thiab cov cim yog siv los ua kom pom cov yam ntxwv ntawm cov xim hlau, thiaj li hloov cov paib hlau, thiab feem ntau yog siv rau hauv cov khoom, xws li cov khoom siv hauv tsev thiab cov khoom siv niaj hnub.
Qhov thib ob, thaj chaw loj ntawm qhov chaw luam ntawv lossis yin luam ntawv yog siv los hloov cov txheej txheem loj hauv cheeb tsam, xws li cov ntawv caw thiab cov ntawv sau ua lag luam. Aluminium ntawv nyiaj tsis tshua muaj luam tawm hauv mesh tones.
Aluminium ntawv ci muab faib ua ob txoj kev luam ntawv: daim ntawv web thiab daim ntawv pub noj.
(1) Web printing. Feem ntau letterpress printing. Cov qauv yooj yim thiab cov ntawv sau ua ke tuaj yeem txiav rau hauv cov nplooj ntawv thiab muab tso rau ntawm lub txee kom qhuav kom daws tau qhov teeb meem ntawm tus number case kom qhuav. Cov qauv loj hauv cheeb tsam thiab cov ntawv lo uas yuav tsum tau sau npe tsis siv neeg yuav tsum tau luam tawm nrog UV number case. Nws yog qhuav tsis muaj UV
Nyob rau hauv rooj plaub no, txoj kev ntawm laminating feem ntau yog siv los daws cov teeb meem ziab ntawm tus number case.
(2) Sheet-fed printing. Feem ntau offset printing, haum rau loj-thaj chaw, mesh printing. Vim yog kev luam ntawv tas mus li ntawm ib daim ntawv, kev ziab tsis zoo ntawm tus number case yog ib qho yooj yim ua rau muaj ntau yam teeb meem zoo, txhawm rau ua kom cov luam ntawv zoo thiab zoo, cov kev ntsuas hauv qab no yuav tsum tau ua.
a. Siv tus cwj mem tshwj xeeb rau txhuas lub thawv ntawv
b. Ntxiv qhov tsim nyog tus nqi ntawm cov desiccant rau tus number case los ua kom qhov ziab nrawm ntawm tus number case.
c. Ntxiv 20% -25% cawv rau cov tshuaj dampening kom txo tau cov emulsification ntawm ya raws thiab number case thiab tiv thaiv kom txhob qias neeg.
d. Master tus nqi ntawm cov ntawv stacking (feem ntau 20-30 cov ntawv yog tsim nyog), muab tso rau ntawm lub txee kom qhuav, thiab tsis txhob adhesion los ntawm qhov hnyav ntawm daim ntawv.
e. Kho cov viscosity thiab thickness ntawm tus number case, thiab ntxiv additives raws li qhov tseeb qhov teeb meem.
f. Khaws qhov chaw tsim khoom ntawm lub rooj cob qhia luam ntawv, thiab qhov kub thiab txias yog tswj ntawm 18-21 degree, kom tus number case nyob rau hauv qhov zoo tshaj plaws.
