Ink Factors Affecting Print Gloss
1Ingi firimu ukobvu
Mune bepa kuti kuwedzere kutorwa kweinki mushure mekubatanidza, iyo yakasara linker ichiri kuchengetwa mufirimu yeinki, iyo inogona kunyatso kuvandudza kupenya kwekudhinda. Iyo yakakora iyo inki firimu, iyo yakawanda yakasara linker, inonyanya kubatsira pakuvandudza kupenya kwekudhinda.
Gloss pamwe nekuwedzera kwehupamhi hwefirimu yeinki uye kuwedzera, pasinei neinki imwe chete, asi kuumbwa kwemapepa akasiyana-siyana ekudhinda gloss nehupamhi hwefirimu yeinki uye kuchinja kwakasiyana. High gloss coating bepa muinki firimu rakatetepa, kudhinda gloss nekuwedzera kweinki firimu ukobvu uye kuderedza, izvi zvinokonzerwa neingi firimu masks bepa pacharo yepakutanga yakakwirira gloss, uye iyo inki firimu pachayo yakaumbwa ne gloss uye nekuda kwe kutora mapepa uye kuderedza; nekuwedzera zvishoma nezvishoma mukukora kwefirimu reinki, bepa riri pakubata kwekubatanidza zvinhu rinonyatsozadzwa mushure mekuwedzera kwenhamba yekubatanidza zvinhu zvakachengetwa pamusoro, uye kupenya kunogara kuchivandudza.
Coated kadhibhodhi anodhinda gloss pamwe kuwedzera ingi firimu ukobvu anowedzera nokukurumidza, ari ingi firimu ukobvu akawedzera kusvika 3.8μm pashure gloss hakuchazovi kuwedzera nekuwedzera ingi firimu ukobvu.
2Ink fluidity
Ink fluidity yakakura kwazvo, dot rinowedzera, saizi yedhindi inowedzerwa, iyo inki layer inova mutete, kudhinda gloss kwakashata; inki fluidity idiki kwazvo, yakakwira gloss, inki haisi nyore kuendesa, asiwo haikodzeri kudhinda. Nokudaro, kuti uwane gloss iri nani, inofanira kudzora fluidity yeinki, kwete yakakura kwete duku.
3Ingi inokwenenzverwa
Muchidhindo chekudhinda, kuenzana kweinki kwakanaka, ipapo kupenya kwakanaka; kusaenzana kwakashata, nyore kudhonza, ipapo kupenya kwakashata.
4Pigment zvirimo muinki
Iyo yakakwira pigment yemukati yeinki inogona kuumba nhamba yakakura yediki capillaries mukati meiki firimu. Uye idzi nhamba hombe yeakanaka capillary kuchengetwa kwekugona kubatanidza zvinhu, kupfuura iyo bepa pamusoro peiyo fiber gap kutora kugona kwekubatanidza zvinhu zvakakura. Naizvozvo, kana zvichienzaniswa neingi dzine pigment yakaderera, ingi dzine pigment yakakwira inokwanisa kuita kuti firimu reinki rirambe rakabatanidza. Kupenya kwezvinhu zvakadhindwa uchishandisa ingi dzine pigment yemhando yakakwirira kupfuura iyo ingi ine pigment yakaderera. Naizvozvo, iyo capillary network chimiro chakaumbwa pakati peinki pigment particles ndicho chinhu chikuru chinokanganisa kupenya kwekudhinda.
Mukudhinda chaiko, kushandiswa kwemafuta eku gloss nzira yekuwedzera gloss yekudhinda, nzira iyi yakasiyana zvachose nenzira yekuwedzera pigment yemukati inki. Iyi nzira mbiri dzekuwedzera kupenya kwekudhinda mukushandisa, zvinoenderana nezvikamu zveinki uye kudhinda ingi firimu ukobvu kusarudza.
Iyo nzira yekuwedzera iyo pigment yemukati inoganhurwa nekudiwa kwekubereka kwemavara mukudhinda kwemavara. Ingi inogadzirwa nediki pigment particles, kana pigment yemukati yadzikira, kupenya kwekudhinda kunodzikira, chete kana firimu reinki rakakora kuti ribudise kupenya kwepamusoro. Nokudaro, nzira yekuwedzera pigment content inogona kushandiswa kuvandudza kubwinya kwechinyorwa chakadhindwa. Nekudaro, huwandu hwepigment hunogona kungowedzerwa kune imwe muganhu, zvikasadaro zvichave nekuda kweiyo pigment zvimedu hazvigone kuvharwa zvachose nekubatanidza zvinhu, kuitira kuti iyo inki firimu pamusoro pechiedza chekuparadzira chiitiko chiwedzere pane kutungamirira kune a. kuderedza kupenya kwechinhu chakadhindwa.
5 Saizi ye pigment zvidimbu uye dhigirii rekupararira
Saizi yepigment particles munzvimbo yakapararira inogadzirisa zvakananga mamiriro einki firimu capillary, kana iyo inki zvidimbu zvidiki, inogona kuumba mamwe madiki capillary. Wedzera kugona kwemufirimu weinki kuchengetedza chinongedzo uye kuvandudza kupenya kwekudhinda. Panguva imwecheteyo, kana pigment particles yakapararira zvakanaka, inobatsirawo kugadzira firimu reinki rakatsetseka, iro rinogona kuvandudza kubwinya kwekudhindwa. Zvinhu zvinotonga zvinokanganisa dhigirii rekupararira kwe pigment particles ipH ye pigment particles uye huwandu hwezvinhu zvinoputika muinki. Kupararira kwe pigment particles kwakanaka kana pH kukosha kwe pigment yakaderera uye zviri mukati mezvinhu zvinoputika muinki zvakakwirira.
6Kujeka kweinki
Mushure mekunge firimu reinki raumbwa neingi nekujeka kwepamusoro, chikamu chechiedza chechiitiko chinoratidzwa nepamusoro pefirimu yeinki, uye chimwe chikamu chinosvika pamusoro pepepa uye chinoratidzwa zvakare, chichiita kusvibiswa kwemavara maviri, uye izvi. kufungisisa kwakaoma kunowedzera mhedzisiro yemuvara; nepo ingi firimu inoumbwa neopaque pigment inongopenya chete nekuratidzwa kwepamusoro, uye mhedzisiro yegloss haina kunaka senge ingi inoonekera.
7Gloss yekubatanidza zvinhu
Kupenya kwechinhu chekubatanidza ndicho chinhu chikuru chekuti inki inodhinda inogona kuburitsa gloss, iyo yekutanga inki yekubatanidza zvinhu kune linseed mafuta, tung mafuta, catalpa mafuta uye mamwe mafuta emiriwo, kutsetseka kwepamusoro pefirimu mushure mekunge firimu raitwa. kwete yakakwirira, inogona chete kuratidza mafuta firimu pamusoro, chiitiko chiedza kuumba diffuse reflection, kupenya kwekudhinda kwakashata. Mazuva ano, chinongedzo cheingi chinonyanya kuumbwa neresin, uye kutsetseka kwepamusoro kweinki mushure mekuputirwa kwakakwira, uye kupenya kwakapararira kwechiedza chechiitiko kunoderedzwa, nokudaro kupenya kweinki kwakapetwa kakawanda kupfuura kuya ingi yekutanga.
8Kuomesa ingi
Huwandu hwakafanana hweinki uchishandisa nzira dzakasiyana dzekuomesa, kupenya hakuna kufanana, kazhinji oxidized firimu kuomeswa pane kupinda kuomesa gloss yakakwirira, nekuti oxidized firimu kuomeswa neingi mune firimu-kuumba linker zvinhu zvakanyanya.
Nzira yekuvandudza sei kudhinda gloss?
1 Deredza inki emulsification
Deredza dhigirii yeinki emulsification. Kudhinda kweoffset muinki emulsification kunonyanya kukonzerwa nekushanda kwemvura neingi, iyo inodhinda inoita senge gobvu reingi, asi iyo inki mamorekuru mune mamiriro emafuta ari mumvura, kuomesa gloss kwakashata zvakanyanya, uye kuchaburitsa nhevedzano. zvekumwe kukundikana.
2 Zvinowedzerwa zvakakodzera
Wedzera zvakakodzera ebetsero muinki, unogona kugadzirisa printability ingi kuitira kutsetseka kudhinda. General ebetsero akawedzera uwandu ingi, havafaniri kupfuura 5%, kana ukafunga mugumisiro Gloss, inofanira kuva shoma kana kusaisa. Asi iyo fluorocarbon surfactant yakasiyana, inogona kudzivirira inki layer yeorenji peel, wrinkles uye humwe hurema hwepamusoro, uye panguva imwechete inogona kuvandudza pamusoro peiyo print gloss.
3 Kushandiswa kwakakodzera kwemafuta ekuomesa
Kushandiswa kwakarurama kwemafuta ekuomesa. Kune yakakwirira-yepamusoro-inopenya inokurumidza-kuomesa inki, kana iri tembiricha uye humidity yakajairika, pachayo ine yakakwana yekuomesa simba.
Mumamiriro ezvinhu anotevera, mafuta ekuomesa anofanira kuwedzerwa:
① Kana iri tembiricha yakaderera uye hunyoro munguva yechando;
② inki inofanira kuwedzerwa kune anti-adhesive, anti-adhesive, yakaonda inki kugadzirisa mafuta, nezvimwewo, inofanira kuwedzerwa kumafuta ekuomesa.
Mukushanda kwekushanda, kushandiswa kwakarurama kwemafuta akaoma, kuitira kuumbwa kwechigadzirwa chakapedzwa gloss chinonyatsonaka. Izvi zvinodaro nekuti bepa rekutora chinongedzo chinoda imwe nguva yenguva, mukuita, nekukurumidza sezvinobvira kuita chinongedzo chekubatanidza zvinhu, kusvika iyo firimu yaoma, ndiyo kiyi yekupedzisa chigadzirwa gloss.
4 Kugadziriswa Kwemuchina
Nyatsogadzirisa muchina. Kunyangwe iyo inki layer yekudhinda inosvika pachiyero, inewo kukanganisa pane gloss. Semuyenzaniso: kushambidzika kwekumanikidza, dot kuwedzera mwero wakakwira, ukobvu hweinki layer hauenderane neyakajairwa, iyo yakapedzwa chigadzirwa gloss yakashata zvishoma. Naizvozvo, kugadzirisa kudzvanywa, kuitira kuti dot kuwedzera mwero kutonga kunenge 15%, yakadhindwa chigadzirwa inki layer yakakora, nhanho uye kudhonza kuvhurika, gloss iripo zvakare.
5 Gadzirisa inki concentration
Wedzera Fanli mvura (No. 0 mafuta), iyi mafuta viscosity yakakura kwazvo, yakakora, inogona kugadzirisa inki yekuisa, kuitira kuti inki yakaonda kuti iwedzere, kuwedzera kupenya kwechigadzirwa chakadhindwa.
