Sib nqus luam ntawv yog ib txoj kev luam ntawv siv cov ntawv sib nqus sib xyaw nrog cov hmoov hlau oxide. Sib nqus luam ntawv yog ib qho tshwj xeeb sau nruab nrab uas tsim los ntawm kev sib xyaw ntawm cov ntaub ntawv siv tshuab thiab tshuab luam ntawv. Nws cov yam ntxwv yog tias cov ntaub ntawv tuaj yeem sau thiab nyeem ntawm daim npav sib nqus, thiab cov lus, cov qauv, thiab cov duab tuaj yeem pom pom.
Sib nqus luam ntawv yog ib daim ntawv los yog yas puag coated nrog ib txheej hlau nplaum, thiab lwm qhov chaw yog luam tawm nrog cov lus los yog cov qauv, thiab cov txheej txheem luam ntawv yog siv los tso saib cov ntaub ntawv pom raws li kev siv, thiab ua tiav los ntawm molding.
Lub hauv paus ntawm magnetic prints yuav tsum muaj zog toughness, uniform thickness, du nto, tsis yooj yim rau stretch los yog curl thaum kub thiab av noo hloov, dej tsis kam thiab corrosion kuj, zoo luam ntawv, thiab ua kom haum, thiab tus nqi qis. Cov ntaub ntawv siv feem ntau yog daim ntawv offset, coated paper, resin-impregnated paper, polyvinyl chloride (PVC), polyethylene terephthalate (PET), thiab lwm yam yas substrates thiab lawv cov ntaub ntawv sib xyaw, nrog lub thickness ntawm 150 thiab 800 microns.
Cov kev xav tau rau cov hmoov sib nqus yog cov hlau nplaum sib nqus, cov khoom me me me, zoo dispersion, stability, thiab kev laus ntev. Feem ntau siv yog maghemite, thiab hlau monoxide txuas rau laum hlau. Magnetic ink yog tsim los ntawm magnetic hmoov pigment, binder, desiccant, antioxidant, wetting agent, thiab lwm yam additives. Ntxiv carbon dub rau dub number case thiab lwm yam xim pigments rau xim number case ua xim.
Sib nqus luam ntawv siv kev tshuaj ntsuam luam ntawv lossis offsets luam ntawv kom tau daim kab xev lossis cov duab sib nqus, uas tuaj yeem tsim cov kab hlau nplaum tsim nyog ntawm daim npav, yog li txo cov nqi, thaum cov ntsiab lus ntawm cov xim sib nqus hauv cov xim sib nqus, cov khoom sib nqus ntawm cov xim, thiab cov tuab ntawm tus number case zaj duab xis txheej tom qab luam ntawv, thiab lwm yam cuam tshuam cov hlau nplaum.
Tom qab cov ntawv sib nqus tau luam tawm, daim ntawv pob tshab PVC yog laminated ntawm ob sab, nias nrog lub xovxwm kub, thiab txiav tuag raws li qhov loj me.
Txhawm rau tiv thaiv kev ua txhaum cai thiab cuam tshuam, kev luam ntawv sib nqus muaj ntau dua thiab ruaj ntseg thiab tsis pub lwm tus paub, yog li cov ntaub ntawv tshwj xeeb lossis thev naus laus zis tau siv hauv cov khoom sib nqus, luam ntawv, thiab cov txheej txheem ua haujlwm. Piv txwv li, cov txheej txheem tshwj xeeb ua cov phaj thiab cov inks yog siv hauv kev luam ntawv, suav nrog kev luam ntawv nrog cov fluorescent inks, cov xim hloov xim kub, thiab infrared-absorbing inks, thiab ntsuas xws li hauv av qauv luam ntawv, micro printing, thiab zaj sawv holography yog. siv los tiv thaiv kev cuav.
Magnetic printing yog dav siv nyob rau hauv nyiaj txiag, credit, kev sib txuas lus, chaw ua hauj lwm, ntau lawm tswj, thiab hais txog.
