Ua ntej thiab qhov tseem ceeb ntawm Aqueous (dej-raws li) thiab UV txheej tau ua tiav kev siv dav hauv Graphics Arts Kev Lag Luam raws li kev sib tw cov tsho loj. Ob leeg muab kev zoo nkauj thiab kev tiv thaiv, ntxiv tus nqi rau ntau yam khoom luam tawm.
Qhov sib txawv ntawm Kev Kho Mechanisms
Hauv paus, kev ziab lossis kho cov txheej txheem ntawm ob qhov sib txawv. Aqueous coatings qhuav thaum lub volatile txheej Cheebtsam (ntau npaum li 60% dej) raug yuam kom evaporate los yog nyob rau hauv ib feem absorbed rau hauv ib tug ntxeem tau substrate. Qhov no tso cai rau cov coatings 'soluble coalesce los ua nyias, qhuav rau qhov kov, zaj duab xis.
Qhov txawv yog UV txheej yog tsim los siv 100% cov khoom ua kua ua kua (tsis muaj volatiles) uas kho los yog photopolymerize nyob rau hauv ib tug tsawg-zog photochemical cross-linking cov tshuaj tiv thaiv thaum raug mob siab luv wavelength ultraviolet (UV) lub teeb. Cov txheej txheem curing ua rau muaj kev hloov pauv sai, hloov cov kua rau hauv cov khib nyiab sai sai (hloov sib txuas) tsim cov zaj duab xis tawv tawv.
Qhov sib txawv ntawm cov khoom siv
Nyob rau hauv cov nqe lus ntawm daim ntawv thov cov cuab yeej, ob qho tib si tsis tshua muaj viscosity aqueous & UV txheej tuaj yeem siv tau zoo siv tus lej kawg hauv flexo & gravure kua number case printing txheej txheem. Hauv qhov sib piv, lub vev xaib thiab daim ntawv pub offset litho paste number case printing txheej txheem yuav tsum tau muab cov xovxwm-kawg coater ntxiv rau siv cov aqueous lossis UV low viscosity coatings. Cov txheej txheem tshuaj ntsuam kuj yog siv los siv cov txheej txheem UV.
Flexo thiab gravure luam ntawv xovxwm muaj qhov tsim nyog hnyav & aqueous number case drying muaj peev xwm twb tau teeb tsa kom zoo qhuav aqueous txheej. Web offset heat set printing processes kuj tau pom tias muaj peev xwm ziab kom qhuav aqueous coatings. Txawm li cas los xij, nws yog lwm qhov teeb meem thaum xav txog daim ntawv-fed offset litho luam ntawv txheej txheem. Ntawm no kev siv cov coatings aqueous yuav tsum muaj cov khoom siv ziab tshwj xeeb uas muaj cov infrared emitters, cov riam cua kub, thiab cov khoom siv cua tshem tawm.
Qhov sib txawv ntawm Lub Sij Hawm Qhuav
Kev xa khoom txuas ntxiv kuj pom zoo kom muab lub sijhawm ziab ntxiv. Thaum xav txog kev ziab (kho) ntawm UV txheej lossis inks, qhov sib txawv yog nyob rau hauv hom tshwj xeeb ziab (kho) cov cuab yeej xav tau. UV curing systems feem ntau muab UV teeb muab los ntawm nruab nrab siab mercury arc teeb, lossis LED qhov chaw muaj peev xwm txaus los kho tau zoo ntawm txoj kab uas yuav tsum tau ua.
Aqueous coatings yog ceev kom qhuav thiab yuav tsum tau them nyiaj rau kev tu thaum lub sij hawm xovxwm nres. Qhov txawv yog UV txheej nyob twj ywm qhib rau ntawm xovxwm tsuav yog tsis muaj UV teeb. UV inks, coatings, thiab varnishes tsis qhuav los yog ntsaws cov kab mob anilox. Tsis tas yuav tsum ntxuav ntawm cov xovxwm khiav los yog dhau ib lub lis piam, txo qis sijhawm thiab pov tseg.
Ob qho tib si aqueous & UV txheej tuaj yeem muab cov pob tshab siab, thiab ntau qhov kev ua tiav los ntawm siab gloss, los ntawm satin rau matte. Qhov txawv yog UV txheej tuaj yeem muab qhov zoo dua gloss tiav nrog qhov pom qhov tob.
Qhov sib txawv ntawm Cov Txheej Txheem
Aqueous coatings feem ntau muab zoo rub, mar, thiab thaiv tsis kam. Cov khoom tsim tshwj xeeb hauv cov txheej txheem aqueous kuj tuaj yeem muab roj, cawv, alkali, thiab ya raws. Qhov txawv yog UV coatings feem ntau, mus rau ib kauj ruam ntxiv muab qhov zoo dua puas, mar, thaiv, tshuaj, thiab cov khoom ua haujlwm.
Thermoplastic aqueous coatings rau daim ntawv-fed offset litho tau tsim los rau hauv-kab ntub ntxiab dhau qeeb ziab kom qhuav inks, txo qis lossis tshem tawm qhov xav tau cov tshuaj tsuag hmoov siv los tiv thaiv tus number case offsetting. Pile kub yuav tsum tau khaws cia nyob rau hauv thaj tsam ntawm 85-95®F kom tsis txhob softening ntawm qhuav txheej ntawm kub siab, thiab lub peev xwm rau setoff & thaiv. Advantageously, cov khoom tsim tau zoo dua qub vim tias cov ntawv coated tuaj yeem ua tiav sai dua.
Qhov txawv yog UV txheej siv nyob rau hauv-kab ntub dej ntxiab tshaj UV inks yog ob qho tib si kho ntawm xovxwm-kawg, thiab cov nplooj ntawv tuaj yeem ua tiav tam sim ntawd. Thaum UV txheej dhau cov pa litho inks yog suav tias yog aqueous primers raug pom zoo kom muab khi thiab ua raws li cov inks los muab lub hauv paus rau UV txheej. Hybrid UV / pa inks tuaj yeem siv los cuam tshuam qhov xav tau ntawm primer.
Kev cuam tshuam rau tib neeg, zaub mov, thiab ib puag ncig
Aqueous coatings muab huab cua huv, VOC tsawg, tsis muaj cawv, tsis muaj ntxhiab, tsis muaj nplaim taws, tsis muaj tshuaj lom, thiab tsis muaj kuab paug. Ib yam li ntawd, 100% cov khoom siv UV txheej tsim tsis muaj kuab paug tawm, xoom VOC's, thiab tsis yog nplaim taws. Qhov sib txawv yog ntub dej tsis huv UV txheej muaj cov tshuaj tiv thaiv uas yuav muaj cov ntxhiab tsw qab, thiab tuaj yeem ua rau me ntsis mus rau qhov hnyav li khaus, uas tuaj yeem ua rau muaj kev tsis haum rau qee tus neeg. Cov tawv nqaij thiab qhov muag yuav tsum zam. Nyob rau hauv ib daim ntawv zoo, UV curables raug xaiv los ua "Qhov Zoo Tshaj Plaws Tswj Technology" (BACT) los ntawm EPA, txo qis VOC's, CO2 emissions, thiab lub zog xav tau.
Aqueous coatings muaj qhov cuam tshuam rau kev hloov pauv hloov pauv thoob plaws hauv xovxwm khiav vim yog evaporation ntawm volatiles, thiab Ph cuam tshuam. Qhov txawv yog 100% solids UV coatings tswj kev sib xws ntawm cov xovxwm tsuav yog tsis raug UV teeb.
Qhuav aqueous txheej yog recyclable, biodegradable thiab repulpable. Qhov txawv yog thaum kho UV txheej yog recyclable thiab repulpable, lawv qeeb qeeb rau biodegrade. Qhov no yog vim curing cross-links txheej txheej,
ua tau ob qho tib si lub cev thiab tshuaj resistant zog.
Aqueous coatings qhuav nrog clarity ntawm cov dej uas tsis muaj hnub nyoog txog yellowing. Qhov txawv yog tias kho UV txheej kuj tuaj yeem pom cov pob tshab siab, tab sis yuav tsum tau saib xyuas hauv kev tsim vim qee cov khoom siv raw tuaj yeem ua daj.
Aqueous coatings muaj peev xwm ua tau raws li FDA cov cai rau ob qho tib si qhuav thiab / los yog ntub dej greasy sib cuag. Qhov txawv yog tias UV txheej, tshwj tsis yog cov qauv tsim tshwj xeeb, tsis muaj peev xwm ua tau raws li FDA cov cai rau cov khoom qhuav qhuav lossis ntub dej / roj ncaj qha.
Cov txiaj ntsig
Ib cag ntawm qhov sib txawv, cov dej hauv dej & UV txheej qhia ntau yam txiaj ntsig rau ntau qib sib txawv. Piv txwv li, cov formulations tshwj xeeb muaj peev xwm muab cua sov, roj, cawv, alkali, thiab ya raws. Tsis tas li ntawd, lawv muaj peev xwm muab cov gluability los yog kua nplaum tiv thaiv, ntau yam ntawm COF, imprint peev xwm, kub los yog txias ntawv txais, muaj peev xwm los tiv thaiv hlau inks, nce productivity, in-line processing, ua hauj lwm-thiab-tig muaj peev xwm, txuag hluav taws xob, tsis muaj teeb-tawm, thiab nyob rau hauv sheetfed offset tshem tawm cov tshuaj tsuag hmoov.
Peb lub lag luam ntawm Cork Industries yog kev tsim kho thiab tsim cov Aqueous, lub zog kho Ultraviolet (UV), thiab Electron Beam (EB) tshwj xeeb txheej txheej thiab cov nplaum. Cork vam meej ntawm nws lub peev xwm los tsim cov tshiab, cov khoom siv tshwj xeeb uas muaj cov duab kos duab kev lag luam tshuab luam ntawv / coater muaj kev sib tw kom zoo dua.
