Kusintha kwamtundu panthawi yowumitsa inki
Panthawi yosindikiza, mtundu wa inki womwe wangosindikizidwa kumene umakhala wakuda poyerekeza ndi mtundu wa inki wouma. Patapita nthawi, mtundu wa inki udzakhala wopepuka pambuyo pa kusindikiza kuuma; Ili si vuto ndi inki yomwe imakhala yosagwirizana ndi kuwala kowala kapena kusinthika, koma makamaka chifukwa cha kusinthika komwe kumachitika chifukwa cha malowedwe ndi makutidwe ndi okosijeni a filimuyo panthawi yowumitsa. Inki yotsitsimula imalowa ndikuuma, ndipo inki yosanjikiza yomwe yangosindikizidwa kuchokera pamakina osindikizira imakhala yokhuthala. Panthawi imeneyi, zimatenga nthawi kuti filimu yolowera ndi oxidation iume.
Inki yokhayo imakhala yosagonjetsedwa ndi kuwala ndipo imatha
Kuzimiririka kwa inki ndi kusinthika kwamtundu ndizosapeŵeka zikayatsidwa ndi kuwala, ndipo inki zonse zimakhala ndi milingo yosiyaniranapo ya kuzimiririka ndi kusinthika kwamtundu ukayatsidwa ndi kuwala. Inki yamtundu wopepuka imazirala ndikusinthika kwambiri ikayatsidwa kwa nthawi yayitali. Chikasu, chofiyira konyezimira, ndi chobiriwira chimazimiririka mwachangu, pomwe buluu, buluu, ndi wakuda zimazimiririka pang'onopang'ono. Mu ntchito yothandiza, posakaniza inki, ndi bwino kusankha inki ndi kukana kwabwino kwa kuwala. Pokonza mitundu yowala, chidwi chiyenera kulipidwa pakukana kwa inki pambuyo pa dilution. Posakaniza inki, kuyenera kuganiziridwanso kuti kukana kuwala pakati pa mitundu ingapo ya inki.
Chikoka cha acidity ndi alkalinity pepala pa inki kuzimiririka ndi ma discoloration
Nthawi zambiri, pepala ndi lamchere wofooka. Mtengo wabwino wa pH wa pepala ndi 7, womwe ulibe ndale. Chifukwa cha kufunikira kowonjezera mankhwala monga caustic soda (NaOH), sulfides, ndi mpweya wa chlorine panthawi yopanga mapepala, mankhwala osayenera pazamkati ndi kupanga mapepala angapangitse pepala kukhala acidic kapena alkaline.
Kuchuluka kwa mapepala kumachokera ku njira yopangira mapepala, ndipo ena amayamba ndi zomatira zomwe zimakhala ndi zinthu zamchere zomwe zimagwiritsidwa ntchito popanga positi. Ngati chithovu cha alkali ndi zomatira zina zamchere zimagwiritsidwa ntchito, zinthu za alkaline zimalowa mu ulusi wa pepala ndikuchitapo kanthu ndi tinthu ta inki pamapepala, zomwe zimapangitsa kuti azizirala ndi kusungunuka. Posankha zipangizo ndi zomatira, m`pofunika choyamba kupenda thupi ndi mankhwala katundu zomatira, pepala, ndi zotsatira za acidity ndi alkalinity pa inki, pepala, electrochemical zotayidwa zojambulazo, golide ufa, ufa siliva, ndi lamination.
Kutentha kumapangitsa kusinthika ndi kusinthika
Zizindikiro zina zopakira ndi zokongoletsera zimamangiriridwa ku zophikira mpunga zamagetsi, zophikira zokakamiza, masitovu amagetsi, ndi ziwiya zakukhitchini, ndipo inkiyo imazimiririka ndikusinthika pakatentha kwambiri. Kukana kutentha kwa inki ndi kuzungulira madigiri 120 Celsius. Makina osindikizira a offset ndi makina ena osindikizira sagwira ntchito pa liwiro lalikulu pamene akugwira ntchito, ndipo zodzigudubuza za inki ndi inki, komanso mbale ya inki ndi mbale zosindikizira zimatulutsa kutentha chifukwa cha kukangana kothamanga kwambiri. Panthawi imeneyi, inki imapanganso kutentha.
Kusintha kwamtundu komwe kumachitika chifukwa cha kutsatizana kolakwika kwa mtundu posindikiza
Mitundu yomwe imagwiritsidwa ntchito kwambiri pamakina anayi amtundu wa monochrome ndi: Y, M, C, BK. Makina amitundu inayi ali ndi mtundu wotsatizana wa: BK, C, M, Y, womwe umatsimikizira inki yosindikiza kaye kenako, zomwe zingakhudze kufota ndi kusinthika kwa inki yosindikiza.
Pokonza ndondomeko ya mitundu yosindikizira, mitundu yowala ndi inki zomwe zimakhala zosavuta kuzimiririka ndi kusinthika ziyenera kusindikizidwa poyamba, ndipo mitundu yakuda iyenera kusindikizidwa pambuyo pake kuti zisawonongeke ndi kusinthika.
Kusintha kwamtundu ndi kusinthika kwamtundu komwe kumachitika chifukwa chogwiritsa ntchito molakwika mafuta owuma
Kuchuluka kwa mafuta owumitsa ofiira ndi mafuta owumitsa oyera omwe amawonjezedwa ku inki sayenera kupitirira 5% ya inkiyo, pafupifupi 3%. Kuwumitsa mafuta kumakhala ndi mphamvu yothandiza kwambiri mu inki ndipo kumapangitsa kutentha. Ngati kuchuluka kwa mafuta owumitsa ndi kwakukulu, kumapangitsa inkiyo kuzimiririka ndikuwonongeka.
Ngati muli ndi zofunika Packaging, mutha kulumikizana nafe. Monga wopanga ma CD osinthika kwazaka zopitilira 20, tidzakupatsirani mayankho anu oyenera malinga ndi zosowa zanu ndi bajeti.
