Nhungamiro: yemuno UV glazing inogona kuenderana nezvinodiwa zvechigadzirwa glazing, chiratidzo chekutengesa, kurongedza uye kudhinda kunoda kuratidza zvikamu zvekunamira glazing yemuno, glazing mapatani kana ichienzaniswa neakatenderedza mapatani anotaridzika akajeka, akajeka, matatu-dimensional pfungwa, anogona kuburitsa. yakasarudzika artic effect.Iri bepa rinotsanangura muchidimbu iyo yemuno UV glazing process ine chekuita neruzivo, zvirimo zveshamwari zvinonongedza:

Local UV glazing process

Local UV, idhindiro yepamusoro yekupedzisa tekinoroji.Nekuda kwekushandisa kwayo UV varnish ine kupenya kwakanyanya, kujeka uye kupfeka kuramba kune yakasarudzika glazing yeakadhindwa zvinyorwa uye zvinyorwa.Ndichiri kuratidza iyo theme yedhizaini, zvakare inovandudza iyo yekushongedza kwepamusoro mhedzisiro yezvigadzirwa zvekudhinda, izvo zvinonyanya kushandiswa mumavhavha emabhuku uye post-press yekushongedza yezvigadzirwa zvekurongedza.

1, UV maitiro

Parizvino, yakajairika yenzvimbo UV mhedzisiro ndeye: mwenje wenzvimbo, kupera kwenzvimbo, kugaya kwenzvimbo, ruvara rwemunharaunda refraction, wrinkles emunharaunda uye maruva echando emuno.

UV yemunharaunda inogona kuitwa mushure mekucheka, asiwo pane yakadhindwa yakananga kupenya, asi kuitira kuratidza mhedzisiro yekupenya kwenzvimbo.Kazhinji, inoitwa mushure mekudhindwa, uye kazhinji yakafukidzwa nematte firimu, inoverengera ingangoita 80% yemuno UV glazing zvigadzirwa.

Musiyano mukuru uripo pakati pekupenya kwemukati uye yakazara vhezheni glazing ndewekuti imwe inodiwa kugadzira ndiro yekutsikirira uye imwe yacho kuve nezvimwe zvinodiwa zvekunyoresa zvemidziyo yekupenya.Local UV glazing ine zvinhu zvitatu, kureva, glazing ndiro, kunyoreswa kwemidziyo uye michina yekurapa.Kuti uve nechokwadi chekuti nzvimbo yeUV glazing yemunharaunda inoenderana nehukuru hwemavara akadhindwa uye mufananidzo, iyo photosensitive imaging nzira inofanirwa kushandiswa pakugadzira ndiro inopenya.

2, iyo yakasarudzika

Kudhinda kupenya kwenzvimbo

Kudhinda sikirini kune hunhu hwekuchinjisa inki yepamusoro, gobvu inki layer uye yakasimba-matatu-dimensional pfungwa.Kupenya nescreen plate kunofanirwa kusarudzwa 200 ~ 300 mesh skrini (yemunharaunda matte yemuno ruvara glazing maitiro, mesh nhamba yakadzikira), tension network tension mu20 ~ 25N/CM.Nokuti mari yemidziyo haina kukura.Mabhuku mazhinji uye mafekitori ekurongedza mukuwedzera kwebhizimusi renzvimbo inopenya, anofarirwa kudhinda skrini.

Flexo local glazing

Kudhinda kweFlexographic kunoratidzwa nekugona kuumba machira akakora nenzira iri nyore.Nokudaro, inonyanya kufarirwa muUV glazing.Flexographic kudhinda yemuno glazing yakakamurwa kuita yakajairwa flexographic printing glazing uye yakakosha flexographic printing glazing, uye mamwe mavara akareruka uye mufananidzo achiri kushandisa yakavezwa rabha letterpress.

Flexographic kudhinda yemuno glazing yakakodzera kupenya kwekunze kana pa-line glazing.Adopt flexographic printing glazing method, shanda pamwe neanilox roller uye cavity type scraper, inogona kunyatso kudzora huwandu hwekupenya, glazing quality yakagadzikana.

Gravure local glazing

Kudhinda kwegravure nekuda kweiyo inki yekudhinda yakakora uye iyo concave dhiramu kudhinda kuramba yakakwira muUV glaising yemuno zvakare ine zvakanakira, kunyanya kubuda kwemuchina wekudhinda mashizha ekugadzira glaising yemuno kwaita basa mukusimudzira.Asi nekuda kwekukwira kwayo seihan mutengo unonyanya kushandiswa kune refu shanduro glazing bhizinesi.

Dzimwe nzira dzenzvimbo dzekupenya

Pamberi pekuuya kweVV varnish, hapana aizoshandisa offset kudhinda kupenya nekuti iyo inki yekudhinda yakatetepa.Uye UV varnish nekuda kwefirimu gobvu, gloss yakakwira uye ine mukana weiyo yakakwira overprint chaiyo mukupenya kweUV yemuno inewo mamwe maapplication asi anonyanya kushandiswa kupenya pamhepo.

Kubva pamaitiro ekugadzira, emuno UV glazing muchina unogona zvakare kukamurwa kuita kunze kwemhepo kupenya uye kupenya kwepamhepo.Offline mwenje inoreva kudhinda, kupenya pamidziyo yakakosha, zvichiteerana, inoda kushandisa yakakosha glazing muchina kana calender.Offline glazing, nekuti iyo yakadhindwa inogona kuomeswa zvizere, saka inogona kuwana yakakwirira kupenya kupfuura kupenya kwepamhepo.Uye zvakare, off-line glazing kugadzirwa kuchinjika.

Mari shoma mumidziyo.Kupenya pamhepo kunoreva kudhinda uye kupenya kunoitwa pamutsetse mumwe wekugadzira, kureva kuwedzera glazing uye UV kurapa michina kumuchina wekudhinda.Kuita kuti chinhu chakadhindwa chikwenenzverwe mushure mekudhindwa.

Local UV tekinoroji nyowani

①Tekinoroji yeinki yakasanganiswa

Nekuti iyo UV kudhinda kana UV glazing haina kukodzera kushandiswa mune inonyudza yakasimba substrate pamusoro, uye varombo pamusoro peiyo inodhinda inki adhesion, saka zvakanyanya kudiwa kwepamhepo UV glazing, kana vese vachishandisa UV kudhinda inki, inosungwa. kuwedzera mitengo: kana uchishandisa yakajairwa inki kudhinda, kugadzirwa kweakavharidzirwa kana kupenya kwakazara, izvo pasina mubvunzo zvaitadzisa kushandiswa kweoffset kudhinda pamhepo glazing.

Yakasanganiswa inki tekinoroji inoshanda kugadzirisa dambudziko iri rebhodhoro.Inosanganisa zvakanakira inki yeUV uye inki yechinyakare maererano nekuita, ndiko kuti, zvakanakira kurapa kwechiedza uye oxidation polymerization kuomeswa, inovandudza synergistic mhedzisiro yeingi pamusoro uye UV varnish, uye inovhura nzira yekudhinda kudhinda pamutsara wekupenya.

② reverse glazing

Pro-cure inoenderana neyechinyakare glazing yemuno.Tora nzira yechinyakare yekupenya (flexographic printing screen printing kana gravure printing) yekupenya kwenzvimbo, pakupedzisira inofanira kushandisa printing yenzvimbo yeglazing plate, kuitira kuti uwane kusiyanisa kwakanyanya kwemavara emunharaunda uye mufananidzo, saka kupenya uye kudhinda overprint chaiyo ndiyo kiyi. kuita glazing process.Iyo reverse glazing process inotyora mitemo iri pamusoro, kuitira kuti dambudziko rekunyoresa rigadziriswe.

③Pamhepo UV kupenya

Online glazing ye flexographic printing uye gravure printing, haina kutaurwa kuva tekinoroji nyowani, uye kune huwandu hwakakura hwemashandisirwo, kudhinda kurongeka uye kukurumidza kukurumidza kudhindisa, kuri mukusiyanisa uye kukosha-akawedzera masevhisi akatangwa aine mazano matsva ekupenya. teknolojia.

Pane mafomu mana makuru e-on-line UV mwenje akaiswa:

UV inki + UV glazing;

Ingi yakasanganiswa + UV glazing;

UV inki + OP mafuta + UV glazing (reverse glazing);

Ingi yakajairika + kupenya kaviri (kupenya kwemvura + kupenya kweUV).

3. Nyaya dzinoda kutarisirwa

1) Zvinodiwa pakudhinda inki additives.

Kana iyo yemuno UV glazing yakananga pamusoro pezvigadzirwa zvekudhinda, iyo inki yekudhinda haifanirwe kuwedzera kana kuwedzera akasiyana-siyana ekuwedzera zvishoma sezvinobvira, senge adhesive inobvisa agent, inki mafuta, kuitira kuti isakanganise polarity yepasi. iyo inki layer, zvichiita kuti mafuta enguva yechiedza uye inki layer adhesion fastness haina kunaka, mafuta akareruka akaturikidzana ari nyore kudonha, kuitira kukanganisa zvakanyanya kupenya.

2) Zvinodiwa pakudhinda poda spraying.

Huwandu hwekupfapfaidza hupfu hunodiwa huve hudiki.Huwandu hukuru hwehupfu hwekupfapfaidza huchaumba hupfu hwehupfu pamusoro pechinyorwa chekudhinda, zvichikonzera kuti UV mafuta layer haikwanise kusungirirwa kune inki layer, nyore kudonha, ichiratidza chidimbu chemhute yegore, iyo inokanganisa zvakanyanya glazing effect.Kana huwandu hwehupfu husina kudzorwa zvakanaka panguva yekudhinda, hupfu hunofanira kubviswa nekukwesha nemaoko kana zvichidikanwa.

3) Zvinodiwa zvekumanikidzana kwepamusoro pezvigadzirwa zvakavharwa.

Nekuda kwezvigadzirwa zvemuno UV glazing mushure mekuputira, zviri nani kushandisa mativi ese efirimu mushure mekurapwa kwekorona, ndiko kuti, kushushikana kwepamusoro pamativi ese efirimu kusvika kupfuura 38Mn / m, kuitira kuti uve nechokwadi chekuti. UV varnish inogona kusungirirwa zvakasimba kune firimu.Panguva imwecheteyo, zvakare tarisa iyo firimu yakashandiswa.
