Inki ndi yopepuka - imagonjetsedwa ndi kusinthika ndi kusinthika

Inki mu kuwala kwa dzuwa, mtundu wake ndi kuwala zidzasiyana mosiyanasiyana kusintha, mtheradi kuwala kukana ndipo sasintha kamvekedwe ka inki si, mu kuwala kwa dzuwa, onse inki mtundu adzabala mosiyanasiyana kusintha.Pali mitundu iwiri ya kusintha.

Kuzimiririka: pansi pa kuwala kwa dzuwa ultraviolet cheza, inki kuwala kukana ndi osauka, anataya choyambirira kuwala mtundu, mtundu amakhala wotumbululuka imvi.Makamaka inki yamtundu wopepuka komanso mitundu inayi yosindikiza ikakhala yachikasu ndi yofiyira mitundu iwiri imazimiririka mwachangu, ndipo inki ya cyan ndi inki imazimiririka pang'onopang'ono.

Kusintha kwamtundu: mosiyana ndi kusindikiza kwa inki wakuda, kusintha kwa mtundu pansi pa kuwala kwa dzuwa kumakhala mdima, mtundu wasinthanso, anthu amatcha kusinthaku kusinthika.

Zotsatira za emulsification

Offsctdruckmasenten mbale yosindikizira sangathe anasiyanitsidwa wetting akusowekapo mbali ya mbale, offscdruckmasenten ndi madzi oyamba pa inki, madzi mosalephera kuoneka emulsifying chodabwitsa.Inki emulsion mtundu adzakhala attenuate, koma, pambuyo evaporation madzi akhoza kubwezeretsa mtundu wapachiyambi, kotero madzi kwambiri, ndi kuchuluka kwa emulsion, adzachititsa mabala.Makamaka, mlingo wa emulsification osiyana kotheratu kamvekedwe ka inki pamodzi, chodabwitsa cha ma discoloration makamaka otchuka.

Mapepala katundu pepala pamwamba kusalala

Paper pamwamba kusalala ndi imprinting buku ali ndi ubale wapamtima, osati pepala yosalala nthawi zambiri amafuna kupanikizika kwambiri, kuti inki ndi kukhudzana wabwino.Monga kusindikiza inki mamasukidwe akayendedwe, liquidity, kukhala ndi kuchuluka kwa inki filimu makulidwe, kuwonjezereka kuthamanga nthawi zambiri zimapangitsa molecularly kufalitsa kufalitsa m'dera, pa nthawi yomweyo, pepala mivi m'malo, koma kukhudzana osauka, monga: TACHIMATA pepala ndi newsprint mu zomwezo mbale kusindikizidwa imprinting zotsatira ndi lalikulu kusiyana, mwachionekere kusiyanitsa osiyana kusindikiza zotsatira.

Absorbability pepala

Pepala, komanso kukula kwa kuyamwa ndi kugawanika tingati ali ndi ubale wachindunji, kawirikawiri mu khalidwe kusindikiza zinthu ndi lotayirira mapepala a pepala, ngati inki liquidity, otsika mamasukidwe akayendedwe, pepala adzakhala kuyamwa zambiri inki wosanjikiza kugwirizana, ngati ubweya stoma. m'mimba mwake kuposa awiri a pigment particles, ndiye, ngakhale inki ndi mpweya, machulukitsidwe imprinting amachepetsa.Muyenera kuwonjezera makulidwe a inki moyenerera.Komabe, kuonjezera makulidwe a inki wosanjikiza, pa mphindi embossing kungachititse "kufalikira", zimakhudza zotsatira imprinting buku.Absorbability ya pepala yaing'ono, kungachititse ambiri inki filimu kuonekera pamwamba pa pepala, kuti anadinda inki wosanjikiza ali machulukitsidwe wabwino.

Paper permeability pepala permeability ndi lalikulu, adzapanga inki wosanjikiza makulidwe woonda, pepala pamwamba pores lalikulu, komanso kupanga mbali ya pigment particles anali atalowerera mu pepala pa nthawi yomweyo, kotero pali lingaliro la mtundu.Kuti zimenezi zitheke, ntchito padziko akhakula, lotayirira kapangidwe pepala, ndi inki fluidity ndi pepala lalikulu, kulabadira mtundu.

Pigment sagonjetsedwa ndi kutentha

Inki mu kuyanika, kuwala mofulumira - kuyanika mphira kusindikiza inki makamaka conjunctiva - makutidwe ndi okosijeni kuyanika.Offset kusindikiza inki kuyanika pasanakhale gawo lokhazikika, inki makutidwe ndi okosijeni polymerization ndi exothermic anachita, kuyanika mofulumira kumapereka kutentha kwambiri, ngati kutentha kumasulidwa pang'onopang'ono, sikungapangitse kutentha kwa pigment.Mwachitsanzo: inki ya golide imadetsedwa ndikutaya kuwala kwake koyambirira.

Pa nthawi yosindikiza, mapepala osindikizira anaunjikidwa milu, chifukwa zakhala zikuzunza m'miyoyo kwambiri, mbali yapakati ya kusindikiza inki makutidwe ndi okosijeni polymerization exothermic anachita, kutentha n'kosavuta kutumiza, kutentha kwambiri pakati pa mbali ya kusinthika kwambiri. .

Mafuta owuma amakhala ndi mphamvu yopepuka

Inki yamtundu ndi ya kamvekedwe kozizira, chikasu chowala, chobiriwira cha emerald, inki ya buluu ndi mitundu ina, musagwiritse ntchito mafuta owuma ofiira, chifukwa mafuta owuma ofiira omwe ali ndi utoto wofiirira adzakhudza mtundu wa inki yowala.

Mafuta owuma oyera amawoneka oyera, koma conjunctiva imakhala yofiirira pambuyo pa okosijeni.Ngati kuchuluka kwa mafuta owuma koyera kumakhala kochuluka, kusindikizidwa kudzakhala kofiira-bulauni kukauma, pamene mtundu wa inki wakuda monga wobiriwira, wakuda ndi wofiirira ndi mafuta owuma ofiira sudzakhudzidwa kwambiri.

Inki si alkali - kugonjetsedwa

Kusindikiza pepala PH mtengo = 7, ndale pepala ndi abwino kwambiri, ambiri inorganic inki opangidwa ndi asidi inki, zamchere ndi osauka, organic inki asidi, zamchere ndi bwino, makamaka sing'anga buluu, mdima buluu inki adzazimiririka ndi zamchere.Alkali sing'anga wachikasu mu mtundu wofiira, electrochemical zotayidwa zojambulazo sitampu, India adzakhala akale chikasu golide mu zinthu zamchere, palibe gloss, ofooka zamchere pepala kwambiri, nthawi zambiri anakumana mu kusindikiza kumanga pambuyo kupanga lili zomatira zamchere, ngati atanyamula zokongoletsera kusindikiza mankhwala ndi zinthu zamchere monga sopo, sopo, ufa wochapira ndi zina zotero, onse amafuna kuganizira kukana zamchere, kukana saponification wa inki ntchito.

Zokhudza malo osungira

Ambiri kusindikiza mankhwala kwa nthawi yaitali yosungirako, mosalephera kusonyeza chodabwitsa chikasu, zifukwa zotsatirazi mbali zingapo.

Ulusi wa pepala uli ndi lignin komanso kusinthika.Nyuzipepala zomwe zimasindikizidwa pamanyuzipepala nthawi zambiri zimakhala zachikasu komanso zonyezimira.

Offset kusindikiza mitundu inayi dontho overprinter mtundu kusindikiza mankhwala, ambiri dzuwa, nyengo, mphepo ndi mvula, panja kukokoloka kwa kutentha, ndi zina zotero, chifukwa pigment si kuwala kugonjetsedwa, kutentha kugonjetsedwa, ndi mtundu kapena kuzimiririka.

Zomwe zimasintha mtundu wa zinthu zosindikizidwa ndizosiyanasiyana ndipo palibe mankhwala omwe angachite chilichonse.Monga sutikesi yamapepala iyi, mtundu wake ukhoza kusintha pakapita nthawi.Koma osachepera ndi wokongola pamene ife ntchito.
