Cov khoom siv raw siv hauv kev tsim cov PTP aluminium ntawv ci yog muaj cov ntawv txhuas ntshiab, uas feem ntau yuav tsum muaj lub thickness ntawm {{0}}.02 hli, lub zog tensile ntawm 98kPa, a rupture lub zog ntawm 90kPa, ib tug huv si, tiaj tus nto, tsis muaj wrinkles, tsis muaj indentation puas, tsis muaj fluorescent khoom nyob rau hauv tej daim, thiab ib tug nto wetting nro ntawm tsis tsawg tshaj li 32. Lub pinhole degree ntawm aluminium ntawv nyiaj rau kev siv tshuaj yuav tsum tsis txhob. ntau tshaj 1/m2 ntawm 0. Qhov yuav tsum tau ntawm pinhole degree rau kws tshuaj txhuas ntawv nyiaj yog 0.1-0.3mm inch, tsis ntau tshaj 1 pinhole / m2. Txij li thaum pinhole yog ib qho tsis xws luag hauv cov ntawv ci txhuas, thiab kev nkag mus ntawm oxygen, dej vapor thiab lub teeb rau hauv cov tshuaj yuav txo qhov kev ua tau zoo ntawm cov tshuaj los yog deteriorate nws, qhov yuav tsum tau ntawm pinhole degree yog nruj heev; Tsis tas li ntawd, lub thickness ntawm aluminium ntawv ci yuav cuam tshuam rau cov txheej txheem ntawm cov nplaum nplaum thiab cov txheej tiv thaiv yog tias nws dhau qhov kev sib txawv (10%), uas yuav tsum tau ua kom pom tseeb ntawm tus neeg teb xov tooj.
Printing number case rau txhuas ntawv ci yog tam sim no muab faib ua ob pawg loj: ib qho yog polyamide number case. Cov cwj mem no muaj qhov zoo adhesion, dispersion, gloss, abrasion tsis kam, zoo hnyav tso tawm thiab softness rau txhua yam ntawm cov ntaub ntawv luam ntawv, thiab feem ntau yog siv nyob rau hauv printing ntawm yas zaj duab xis. Thaum siv rau hauv kev luam ntawv ntawm cov ntaub ntawv aluminium, qhov kev ua tau zoo ntawm cov cwj mem zoo li no tuaj yeem pom, thiab nws cov cua sov kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm aluminium foil luam ntawv. Lwm hom yog vinyl chloride vinyl acetate copolymerization rau hauv resin / propionic acid resin raws li cov khoom tseem ceeb ntawm txhuas ntawv ci tshwj xeeb number case, uas yog cov xim ci, siab concentration, tshwj xeeb tshaj yog muaj zog adhesion nrog aluminium ntawv ci, thiab zoo transparency, tab sis vim yog cov xim ci. siv gravure printing, hnyav volatility yog loj, thiab nws yog ib qho yooj yim mus ua kom qhuav ntawm number case nyob rau hauv lub inking qhov ntawm gravure rollers thiab deposition ntawm tus number case, uas yuav ua rau lub paste phaj tshwm sim thaum nws yog siv nyob rau hauv lub printing ntawm tshuaj. PTP ntawv ci.
Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua raws li qhov tsim nyog pretreatment rau lub deposition thiab khov ntawm tus number case los ntawm nplawm los yog ua kom qhov kub thiab txias (dej da dej) ntawm deposited khov number case. Yog hais tias tus number case cia lub sij hawm ntev dhau lawm, tus number case yuav muab tso rau, ua rau tus number case nyob rau hauv lub txheej txheej ntawm resin tov, qis txheej pigment, lub sab sauv txheej ntawm lub teeb xim, lub qis txheej ntawm tsaus xim, yuav tsum tau. stirred tom qab siv.
