Nkhani - Chidziwitso Chamakampani | Zifukwa Zisanu ndi Ziwiri Zosintha Mtundu wa Zinthu Zosindikizidwa

Pazinthu zosindikizidwa zapamwamba, mtunduwo nthawi zambiri umakhala ndi muyeso wokhazikika: mtundu wa inki wamagulu azinthu uyenera kukhala wofanana kutsogolo ndi kumbuyo, wowoneka bwino, komanso wogwirizana ndi mtundu wa inki ndi mtundu wa inki wa pepala lachitsanzo. .

Komabe, posindikiza ndi kusungirako, mtundu, kupepuka ndi machulukitsidwe azinthu zosindikizidwa nthawi zambiri zimasintha. Kaya ndi inki ya monochrome kapena inki yokhala ndi mitundu yoposa iwiri, mtunduwo ukhoza kukhala wakuda kapena wopepuka pansi pa zotsatira zamkati ndi zakunja.

Poganizira izi, tikambirana nanu lero zinthu zomwe zimakhudza kusintha kwamitundu yazinthu zosindikizidwa, zomwe nthawi zambiri zimaphatikizapo izi:

Kusintha kwa mtundu ndi kuzimiririka kwa inki chifukwa cha kusalolera kwa kuwala

Pansi pa kuwala kwa dzuwa, mtundu ndi kuwala kwa inki kudzasintha mosiyanasiyana. Palibe inki yomwe ilibe kuwala kokwanira popanda kusintha mtundu. Pansi pa kuwala kwa dzuwa, mtundu wa inki zonse udzasintha mosiyanasiyana. Kusinthaku kungathe kugawidwa m'mitundu iwiri.

Kuzimiririka:

Pansi pa kuwala kwa dzuwa kwa ultraviolet, inkiyo imakhala yosakanizidwa bwino ndi kuwala, imataya mtundu wake wowala, ndipo mtunduwo umakhala wotumbululuka mpaka imvi yoyera. Makamaka, mitundu yachikasu ndi yofiira imazimiririka mwachangu mu inki zamtundu wopepuka komanso mitundu inayi yosindikizira, pomwe inki ya cyan ndi inki imatha pang'onopang'ono.

Kusintha kwamtundu:

Mosiyana ndi kutha kwa inki yakuda ya zinthu zosindikizidwa, mtundu umasintha kwambiri chifukwa cha kuwala kwa dzuwa, ndipo mtundu umasinthanso. Anthu amatcha kusinthaku kusinthika.

Zotsatira za emulsification

Chosindikizira chosindikizira sichingasiyanitsidwe ndi kunyowetsa mbali yopanda kanthu ya mbaleyo ndi njira yonyowetsa. Pakusindikiza, madzi amathiridwa kaye ndiyeno inki amaikidwa. Emulsification ndi yosapeŵeka pamene madzi akugwiritsidwa ntchito.

Mtundu wa inki udzachepetsedwa pambuyo pa emulsification, koma udzakhalanso ndi mtundu wake woyambirira madziwo atatha. Chifukwa chake, madzi akamakula, kuchuluka kwa emulsification kumapangitsa kusinthika. Makamaka, inki zamtundu wokhala ndi emulsions yosiyana kwambiri zimasakanizidwa palimodzi, ndipo chodabwitsa cha kusinthika chimakhala chodziwika kwambiri.

Chikhalidwe cha pepala

1.Kusalala kwa pepala

Kusalala kwa pepala pamwamba kumagwirizana kwambiri ndi kopi yosindikiza. Pamwamba pa pepala losafanana nthawi zambiri pamafunika kukakamizidwa kwambiri kuti inki igwirizane nayo bwino. Mwachitsanzo, ngati inki mamasukidwe akayendedwe, fluidity ndi makulidwe inki wosanjikiza amasungidwa pa mlingo winawake, kuonjezera mavuto nthawi zambiri kuonjezera kufalikira dera kusindikiza. Pa nthawi yomweyi, mbali zotsika kwambiri za pepala zimagwirizanabe bwino. Mwachitsanzo, ngati zotsatira zosindikizira za pepala lokutidwa ndi nyuzipepala pa mbale yosindikizira imodzi ndizosiyana kwambiri, zotsatira zosiyana zofananitsa zimatha kufananizidwa bwino.

2.Kuyamwa kwa pepala

The absorbability wa pepala imagwirizananso mwachindunji ndi zotsatira zobwerezabwereza. Nthawi zambiri, pamene kusindikiza pepala lotayirira, ngati inki ali ndi fluidity mkulu ndi otsika mamasukidwe akayendedwe, pepala kuyamwa zambiri inki wosanjikiza zolumikizira. Ngati m'mimba mwake wa pores ndi waukulu kuposa awiri a pigment particles, ngakhale pigment adzakhala odzipereka, amene kuchepetsa machulukitsidwe wa kuganiza. makulidwe a inki wosanjikiza ayenera kuonjezeredwa bwino.

Komabe, kukulitsa makulidwe a inki wosanjikiza kumayambitsa "kufalikira" panthawi yosindikiza, zomwe zingakhudze zotsatira zake. Pepala lokhala ndi mayamwidwe otsika lingapangitse kuti filimu ya inki iwonekere pamapepala, kotero kuti wosanjikiza wa inki wosindikizidwa ukhale wabwinoko..

3.Kutha kwa pepala

Kuchuluka kwa mapepala kumachepetsa makulidwe a inki, ndipo ma pores akuluakulu pamapepala amapangitsanso kuti tinthu tating'ono ta pigment tilowe m'mapepala nthawi imodzi, kotero kuti mtunduwo udzakhala ndi chidziwitso cha kutha. Pachifukwachi, ntchito pepala ndi pamwamba akhakula ndi lotayirira kapangidwe, ndi pepala ndi inki fluidity lalikulu, kulabadira ma discoloration.

Kutentha kukana kwa pigment

Mu kuyanika ndondomeko inki, yowala ndi kudya kuyanika zomatira kusindikiza inki makamaka oxidized conjunctiva kuyanika. Pali fixation siteji pamaso kuyanika kwa offset kusindikiza inki. The makutidwe ndi okosijeni polymerization wa inki ndi exothermic anachita. Ngati kuyanika kukufulumira, kutentha kwakukulu kumatulutsidwa. Ngati kutentha kumatulutsa pang'onopang'ono, pigment yosamva kutentha imasintha mtundu.

Mwachitsanzo, inki yagolide imadetsedwa ndipo imataya kuwala kwake koyambirira.

Posindikiza, mapepalawo amaikidwa mumilu patebulo lolandira mapepala. Chifukwa cha stacking kwambiri, pepala inki pakati ndi oxidized, polymerized ndi exothermic, ndi kutentha si kophweka dissipate. Ngati kutentha kuli kwakukulu, gawo lapakati lidzasintha mtundu kwambiri.

Zotsatira za Mafuta Owuma

Kuwala mitundu inki ndi mitundu ozizira, kuwala chikasu, emarodi wobiriwira, nyanja buluu ndi zina wapakatikati mtundu inki, musagwiritse ntchito ofiira youma mafuta, chifukwa wofiira youma mafuta palokha ali magenta kwambiri, zomwe zidzakhudza mtundu wa inki kuwala.

Mafuta owuma oyera amawoneka oyera, koma amasanduka bulauni pambuyo pa conjunctiva ndi okosijeni. Ngati kuchuluka kwa mafuta oyera owuma ndi aakulu, kusindikiza kowuma kungakhale kofiira kofiira, pamene mtundu wa mafuta ofiira owuma a inki zakuda monga buluu, wakuda ndi wofiirira sudzakhudzidwa kwambiri.

Mphamvu ya kukana kwa alkali ya inki yosindikiza

Mtengo wa pH wa pepala losindikizidwa ndi 7, ndipo pepala losalowerera ndale ndilobwino kwambiri. Nthawi zambiri, inki yopangidwa ndi inorganic pigments imakhala yochepa kwambiri chifukwa cha asidi ndi alkali kukana, pomwe inki yachilengedwe imakhala yabwino kwambiri polimbana ndi asidi ndi alkali. Makamaka, inki yapakati pa buluu ndi buluu wakuda idzazimiririka mukakumana ndi alkali.

Pankhani ya alkali, mtundu wachikasu wapakatikati umasanduka wofiira, ndipo chosindikizira chotentha cha anodized aluminiyamu chojambula ndi kusindikiza golide chidzasanduka chikasu chakale chikakumana ndi zinthu zamchere, popanda kuwala. Pepalalo nthawi zambiri limakhala lofooka komanso lamchere, ndipo chomangira chomwe chili ndi zamchere chimakumana nacho pakapita nthawi yosindikiza ndi kumanga. Ngati zosindikizira ndi zokongoletsera ndikunyamula zinthu zamchere, monga sopo, sopo, ufa wochapira, ndi zina zotero, kukana kwa alkali ndi kukana kwa inki kuyenera kuganiziridwa.

Zokhudza malo osungira

Pali zifukwa zingapo zomwe zosindikizidwa zambiri zimakhala zachikasu zikasungidwa kwa nthawi yayitali.

Ulusi mu pepala amakhala ndi lignin ndi discolor. Mwachitsanzo, nyuzipepala zomwe zimasindikizidwa pamapepala nthawi zambiri zimakhala zachikasu komanso zowonongeka.

Zambiri mwazinthu zosindikizira zamtundu zomwe zimasindikizidwa ndi kusindikiza kwa madontho anayi amtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wanji umasweka kapena kuzimiririka chifukwa cha kukana kopepuka komanso kukana kutentha kwa pigment pansi padzuwa, masiku ataliatali, mphepo ndi mvula, dzimbiri lakunja kutentha, etc.

Inki Hongze amasankha si wapamwamba, komanso amasunga maganizo okhwima poyerekeza mtundu wa mankhwala yomalizidwa mu siteji yotsatira. Ingotipatsani mankhwalawo, ndipo tidzayang'ana zofunikira zilizonse kwa inu.
