Nekuda kwekusiyana kukuru kwenzvimbo yekudhinda tembiricha uye humidity, maitiro emamiriro ezvakasiyana zvivakwa uye printability, yega yega ingi pigment, chinongedzo chinoshandiswa nechikamu chezvinhu uye kuzadza zvinhu zvinenge zvagara, kana zvichiri kutadza kuzadzisa zvinodiwa. mamiriro akasiyana-siyana ekukodzera kudhinda, kudhinda inki additives inogona kuwedzerwa kugadzirisa ingi kuti iite kuti ienderane nezvinodiwa zvekudhinda.Iri bepa rinosuma muchidimbu basa rezvakajairwa inki additives uye maitiro avo ekushandisa, zvirimo kune shamwari referensi:
Ink additives
Ingi yekubatsira zvinhu zvekubatsira zvinoshandiswa kugadzirisa ingi kuti ienderane nemamiriro ekudhinda akasiyana.Kune akawanda marudzi eingi ekuwedzera, anowanzo shandiswa adhesive, kumwaya mwenje mumiriri, desiccant, inononoka kuomesa agent, diluent, friction resistant agent, yekuvhara gloss mafuta, kuwedzera kune akawanda ari pamusoro anowanzo shandiswa inki additives, kune anti fouling agent, anti. -foam agent, mafuta ekudhinda, nezvimwewo Kubva pakuona kwekuvandudza kushandiswa kwekudhinda uye hutano, maererano nekuchinja kwemamiriro ekudhinda, zvinobatsira kuwedzera zvimwe zvinowedzera zvakakodzera muinki dzakasarudzwa kuti zvive nechokwadi chekudhinda kwakajairika.
01 Kubvisa Kwekunamatira
Adhesives ane diki viscosity uye anowanzo shandiswa mune lithography uye yekuyamura kudhinda ingi kuderedza viscosity yavo.Mukudhinda kwe offset, nekuda kwekuchinja kwezvinhu zvemapepa uye mamiriro ekudhinda, sekunyura kwemafuta, kusimba kwepasi pasi, yakanaka uye yakaipa coating inodonha chiitiko, kana desiccant yakawandisa kana tembiricha yekamuri yemusangano wekudhinda yakanyanya kuderera, ichaita. kukonzera bvudzi remapepa, kudhinda stack plate, pasting plate uye zvimwe zvikanganiso, zvinokanganisa kunaka kwekudhinda.Nokudaro, kana chiitiko chiri pamusoro chikaitika, huwandu hwakakodzera hwekunamatira kubvisa mumiririri hunogona kuwedzerwa kuderedza uye kubvisa basa rezvikanganiso zviri pamusoro.
02 Kubva Chiedza Mumiririri
Bvisa diluent, inozivikanwawo sekuti diluent, ihombe yezviwedzerwa zvinodhindwa zve offset.Kune maviri akajairika diluent: imwe imafuta akajeka, anoshandiswa kuita inki inopenya;Imwe iresin - type diluent, inoshandiswa kuita inki resin.Kana iyo inki yekudhinda ruvara yakaonekwa yakadzika zvakanyanya kuti idzorere iyo yekutanga manyoro, unogona kuwedzera huwandu hwakakodzera hwechiedza ajenti, kuitira kuti iwane mhedzisiro yakanaka.
03 Desiccant
Desiccant ndeimwe yeanonyanya kukosha ekudhinda inki anobatsira.Zvinoenderana neakasiyana mamiriro ekudhinda uye pepa rekudhinda, huwandu hwe desiccant, mhando uye nzira yekushandisa zvakasiyana.Iyo inowanzoshandiswa desiccant mafuta matsvuku akaoma, machena akaoma mafuta maviri, mafuta matsvuku akaoma ari kuoma kubva kunze kusvika mukati, mafuta machena akaoma ane kunze panguva imwechete yakaoma.Pakudhinda, ndinosarudza rudzi rwemafuta ekuomesa maererano nezvinodiwa zvekudhinda uye inki ruvara.General dryness mafuta dosage ndeye 2% -3%, yakawandisa inodzosera moto, zvekuti mwero wekuoma wakaderera.
04 Slow Drying Agent
Desiccant inozivikanwawo se antioxidants, iyi desiccant uye inopesana neingi additives.Muchidhindo chekudhinda, nekuda kwezvikonzero zvakasiyana-siyana zvinowanzokonzera kuderera, apo nguva yekudzikisa kwenguva yakareba, inki ichaoma ganda.Kuti ugadzirise rudzi urwu rwedambudziko, zvinowanzodiwa kuwedzera chiyero chakakodzera che desiccant kune inki pamushini, uye mhanyisa muchina nguva shoma, kuitira kuti irege kukurumidza kuoma.
05 Mutete,
Mukudhinda, nekuda kwekunyanyisa inki viscosity kana hurombo bepa kunaka, zvikanganiso zvakaita sekudhonza mvere dzemapepa uye kudonha kweplate kunowanzoitika, izvo zvinokanganisa kudhindwa kwakajairwa.Panguva ino, kunze kwekuwedzera huwandu hwakakodzera hwekunamira kuti uderedze viscidity yeinki, chidimbu chidiki che diluent chinogonawo kuwedzerwa kuderedza viscidity yeinki, kuitira kuti kudhinda kuenderere mberi zvakanaka.Kune akawanda marudzi e diluent, kazhinji yakaderera viscosity matanhatu inki oiri.
06 Resistance To Friction
Friction resistant agent inonziwo smoothing agent.Zvizhinji zvezvinhu izvi zvinobva pane wakisi.Kana zvimedu zveingi zvekudhinda zvakakasharara, senge ingi chena, goridhe uye sirivheri ingi, wedzera huwandu hwakakodzera hwehunopikisa mumiririri kuti uwedzere kukwesha kuramba uye kutsvedzerera kwezvinhu zvekudhinda.
07 Cap Chiedza Mafuta
Zviratidziro, maalbum emifananidzo uye zvimwe zvigadzirwa zvepamusoro-giredhi ekudhinda, nzvimbo yekudhinda zvakanyanya kuburikidza neyakajeka kurapwa, kuitira kuti iwane yakakwirira mwenje mhedzisiro, kushandiswa kwemafuta ekupenya, inogona kusanganiswa muinki yekudhinda isati yadhindwa, inogona zvakare kudhindwa mushure mekudhinda. mafuta anopenya.Asi mushure mekugadzira gloss kudhindwa, mushure menguva refu ichava yero, kupikisa kwechiedza kwakashata, saka ikozvino kune dzakawanda dzimwe nzira kune gloss mafuta emafuta matsva anoiswa.
