Kev taw qhia: UV glazing hauv zos tuaj yeem ua raws li qhov xav tau ntawm cov khoom lag luam glazing, cov cim lag luam, ntim thiab luam ntawv yuav tsum tau ua kom pom tseeb ntawm cov txheej txheem glazing hauv zos, cov qauv glazing piv nrog cov qauv nyob ib puag ncig zoo li ci ntsa iab, ci ntsa iab, peb-dimensional kev nkag siab, tuaj yeem tsim ib tug tshwj xeeb artistic nyhuv.Daim ntawv no piav qhia luv luv txog cov txheej txheem UV glazing hauv zos txog kev paub, cov ntsiab lus rau cov phooj ywg siv:
Local UV glazing txheej txheem
Local UV, yog lub tshuab luam ntawv nto xov.Vim nws siv UV kua roj vanish nrog lub siab ci, pob tshab thiab hnav tsis kam rau xaiv glazing ntawm cov ntawv luam tawm thiab cov ntawv.Thaum hais txog cov ntsiab lus layout, nws kuj tseem txhim kho cov nyhuv kho kom zoo nkauj ntawm cov khoom luam ntawv, uas yog siv rau hauv phau ntawv npog thiab tom qab xovxwm kho kom zoo nkauj ntawm cov khoom ntim.
1, UV effect
Tam sim no, cov nyhuv UV hauv zos yog: lub teeb hauv zos, kev ploj tuag hauv zos, kev sib tsoo hauv zos, cov xim hauv zos refraction, lub hauv paus wrinkles thiab cov paj dej khov hauv zos.
Lub zos UV tuaj yeem siv tau tom qab lamination, tab sis kuj tseem nyob rau ntawm cov ntawv luam tawm ncaj qha glazing, tab sis txhawm rau txhawm rau txhawm rau ua kom pom cov nyhuv ntawm glazing hauv zos.Feem ntau, nws yog nqa tawm tom qab luam ntawv, thiab feem ntau them nrog matte zaj duab xis, suav txog li 80% ntawm cov khoom siv hauv zos UV glazing.
Qhov sib txawv loj tshaj plaws ntawm lub zos glazing thiab tag nrho version glazing yog tias ib tug yuav tsum tau ua ib lub phaj luam ntawv thiab lwm yam yog kom muaj qee yam kev cai rau cov khoom siv glazing.Lub zos UV glazing muaj peb yam, uas yog, glazing phaj, khoom sau npe thiab kho cov khoom.Txhawm rau kom ntseeg tau tias qhov chaw UV glazing hauv cheeb tsam yog raws li qhov loj ntawm cov ntawv luam tawm thiab daim duab, cov duab thaij duab yuav tsum tau siv thaum ua cov phaj glazing.
2, kev cais
Screen luam ntawv hauv zos glazing
Kev tshuaj ntsuam luam ntawv muaj cov yam ntxwv ntawm kev hloov pauv tus lej siab, tuab txheej txheej thiab muaj zog peb-seem.Glazing nrog tshuaj ntsuam phaj yuav tsum tau xaiv feem ntau 200 ~ 300 mesh npo (rau lub zos matte hauv zos xim glazing nyhuv, mesh tooj yog qis), nro network nro hauv 20 ~ 25N / CM.Vim tias cov cuab yeej siv peev nyiaj tsis loj.Ntau phau ntawv thiab ntim cov chaw tsim khoom hauv kev nce hauv kev lag luam glazing hauv zos, yog qhov kev tshuaj ntsuam luam ntawv nyiam.
Flexo hauv zos glazing
Flexographic luam ntawv yog tus cwj pwm los ntawm lub peev xwm los tsim cov txheej tuab dua hauv cov txheej txheem yooj yim.Yog li ntawd, nws yog nrov heev nyob rau hauv UV glazing.Flexographic luam ntawv hauv zos glazing tau muab faib ua cov flexographic luam ntawv glazing thiab tshwj xeeb flexographic luam ntawv glazing, thiab qee cov ntawv yooj yim thiab cov duab tseem siv engraved rubber letterpress.
Flexographic luam ntawv hauv zos glazing yog tsim rau offline glazing lossis on-line glazing.Txais yuav flexographic printing glazing txoj kev, koom tes nrog anilox cov menyuam thiab kab noj hniav hom scraper, muaj peev xwm tswj tau tus nqi ntawm glazing, glazing zoo yog ruaj khov.
Gravure hauv zos glazing
Gravure luam ntawv vim lub tshuab luam ntawv number case yog thicker thiab concave nruas luam ntawv kuj yog siab nyob rau hauv lub zos UV glaising kuj muaj qhov zoo, tshwj xeeb tshaj yog qhov tshwm sim ntawm daim ntawv-fed gravure tshuab luam ntawv rau txoj kev loj hlob ntawm lub zos glaising tau ua lub luag hauj lwm los txhawb.Tab sis vim nws cov nqi seihan ntau dua yog siv rau kev ua lag luam ntev ntev glazing.
Lwm txoj hauv kev glazing hauv zos
Ua ntej lub advent ntawm UV kua roj vanish, tsis muaj leej twg yuav siv offset printing rau glazing vim hais tias cov luam ntawv number case txheej nyias nyias.Thiab UV kua roj vanish vim yog cov zaj duab xis tuab, siab gloss thiab muaj qhov zoo ntawm qhov siab tshaj qhov tseeb hauv zos UV glazing kuj muaj qee qhov kev siv tab sis feem ntau yog siv rau hauv online glazing.
Los ntawm hom kev tsim khoom, lub tshuab UV glazing hauv zos tuaj yeem muab faib ua offline glazing thiab online glazing.Lub teeb offline hais txog kev luam ntawv, glazing ntawm cov cuab yeej tshwj xeeb, raws li, yuav tsum tau siv lub tshuab glazing tshwj xeeb lossis calender.Offline glazing, vim hais tias cov ntaub ntawv luam tawm tuaj yeem qhuav tag, yog li tuaj yeem tau txais lub ntsej muag siab dua li ntawm on-line glazing.Tsis tas li ntawd, off-line glazing ntau lawm yooj.
Kev nqis peev me me hauv cov khoom siv.On-line glazing hais txog kev luam ntawv thiab glazing ua tiav ntawm ib kab ntau lawm, piv txwv li ntxiv glazing thiab UV curing li rau cov xovxwm luam ntawv.Txhawm rau ua kom cov ntawv luam tawm kom polished ncaj qha tom qab luam ntawv.
Local UV technology tshiab
①Mixed number case technology
Vim tias UV luam ntawv lossis UV glazing tsis haum rau daim ntawv thov nyob rau hauv lub absorbent muaj zog substrate nto, thiab cov neeg pluag nyob rau saum npoo ntawm printing number case adhesion, yog li feem ntau ntawm cov kev xav tau rau online UV glazing, yog hais tias tag nrho cov siv UV luam ntawv number case, yog khi. kom nce tus nqi: yog tias siv cov ntawv luam ntawv zoo tib yam, kev tsim cov coated lossis cov glazing dav dav, uas tsis muaj kev txhawj xeeb cuam tshuam rau daim ntawv thov ntawm offset printing online glazing.
Mixed ink technology yog qhov zoo los daws qhov teeb meem no.Nws ua ke qhov zoo ntawm UV number case thiab ib txwm number case nyob rau hauv cov nqe lus ntawm kev ua tau zoo, uas yog, qhov zoo ntawm lub teeb curing thiab oxidation polymerization kom qhuav, txhim kho cov synergistic nyhuv ntawm number case nto thiab UV kua roj vanish, thiab paves txoj kev rau offset printing ntawm kab glazing.
② rov qab glazing
Pro-kho yog txheeb ze rau cov tsoos glazing hauv zos.Siv cov txheej txheem ntawm glazing (flexographic printing screen printing los yog gravure printing) rau glazing hauv zos, thaum kawg yuav tsum siv lub zos glazing phaj luam ntawv, thiaj li yuav ua tau lub siab zoo sib xws ntawm cov ntawv hauv zos thiab daim duab, yog li glazing thiab printing overprint precision yog qhov tseem ceeb. rau glazing txheej txheem.Cov txheej txheem rov qab glazing ua txhaum los ntawm cov cai saum toj no, kom daws tau qhov teeb meem ntawm kev sau npe.
③ Online UV glazing
Online glazing rau flexographic printing thiab gravure printing, tsis tau hais tias yog ib tug tshiab technology, thiab rau ib tug ntau yam ntawm kev siv, luam ntawv raug thiab kub ceev offset printing, yog nyob rau hauv qhov sib txawv thiab cov nqi-ntxiv cov kev pab cuam launched nrog lub tswv yim ntawm glazing. tshuab.
Muaj plaub yam tseem ceeb ntawm on-line UV teeb pom kev zoo uas tau siv:
UV number case + UV glazing;
Mixed number case + UV glazing;
UV number case + OP roj + UV glazing (rov qab glazing);
Ordinary number case + ob glazing (waterborne glazing + UV glazing).
3. Cov teeb meem xav tau kev saib xyuas
1) Yuav tsum muaj rau luam ntawv number case additives.
Yog hais tias lub zos UV glazing yog ncaj qha rau ntawm qhov chaw ntawm cov khoom luam ntawv, cov luam ntawv number case yuav tsum tsis txhob ntxiv los yog ntxiv ntau yam additives tsawg li sai tau, xws li cov nplaum tshem tawm tus neeg sawv cev, number case roj, thiaj li tsis mus cuam tshuam lub nto polarity txheej number case, uas ua rau lub teeb lub sij hawm roj thiab number case txheej adhesion fastness yog tsis zoo, lub teeb roj txheej yooj yim poob tawm, thiaj li mus cuam tshuam rau cov nyhuv glazing.
2) Yuav tsum tau luam ntawv hmoov txau.
Tus nqi ntawm cov hmoov txau yuav tsum yog me me.Cov hmoov txau ntau ntau yuav tsim cov hmoov txheej rau ntawm qhov chaw ntawm cov khoom luam ntawv, uas ua rau UV roj txheej tsis tuaj yeem txuas mus rau cov txheej txheem number case, yooj yim kom poob tawm, qhia txog ib daim ntawm huab huab, uas cuam tshuam rau lub cev. glazing nyhuv.Yog tias tus nqi ntawm cov hmoov tsis zoo tswj tau thaum luam ntawv, cov hmoov yuav tsum tau muab tshem tawm los ntawm tes txhuam thaum tsim nyog.
3) Cov kev xav tau rau saum npoo ntawm cov khoom coated.
Rau qhov xav tau rau cov khoom siv hauv zos UV glazing tom qab txheej, nws yog qhov zoo tshaj plaws los siv ob sab ntawm zaj duab xis tom qab kev kho mob corona, uas yog, qhov nro ntawm ob sab ntawm zaj duab xis kom ncav cuag ntau dua 38Mn / m, thiaj li ua kom ntseeg tau tias UV kua roj vanish tuaj yeem txuas nrog rau zaj duab xis.Nyob rau tib lub sijhawm, kuj tshawb xyuas cov yeeb yaj kiab siv.
