Ukuphila kwethu kugcwele izinhlobonhlobo zezinto ezinyathelisiwe, izingubo zokugqoka, omagazini, nokupakishwa kwazo zonke izinhlobo.Njengabadayisi nabathengi abapakisha ukudla, sikhathazeke kakhulu ngokuthi hlobo luni lukayinki oluhambisana nemvelo futhi lufaneleka kakhulu imboni yokupakisha ukudla.Kulesi sihloko, sizokwethula ngoyinki ohambisana nemvelo ofaneleka kakhulu ukuphrinta ukupakishwa kokudla: uyinki osuselwe emanzini.
Umqondo Woyinki Osekelwe Emanzini
Inqubo yesayensi isetshenziswa ukwenza lokhu okubizwa ngokuthi uyinki osekelwe emanzini, osetshenziswa kakhulu amanzi njengesincibilikisi.Uyinki osuselwe emanzini kanye nabanye oyinki bokuphrinta abanawo umthelela olimazayo empilweni yesisebenzisi somshini wokunyathelisa uma kuqhathaniswa nezincibilikisi zabo ezingaguquguquki, ezinobuthi.Ukuphrinta nakho kuyahambisana nemvelo.I-inki ayinazo izinto ezingashi nje kuphela, kodwa futhi iqeda usongo olufihliwe lokuvutha nokuqhuma endaweni yokusebenzela yokunyathelisa, evumela ukusebenza okuphephile.Yebo, u-inki noyinki manje unezinhlelo ezihlukahlukene zokusebenza: uyinki wokuphrinta we-offset, uyinki wokuphrinta we-flexographic, noyinki wokuphrinta we-gravure. ezinye izindlela zokuphrinta zikayinki ohlukile.E-United States, isibonelo, i-95% ye-flexographic prints kanye ne-80% ye-gravure prints iqukethe uyinki.
Ngaphezu kokuvikelwa kwemvelo, isetshenziswa kabanzi emhlabeni kayinki wamanzi ngenxa yokusebenza kwayo okuphezulu: ukuzinza kombala we-inki, ukukhanya okuphezulu, amandla ombala aqinile, ipuleti elingagqwali, ukunamathela okuqinile ngemuva kokuphrinta, isivinini sokumisa esilungisekayo, ukumelana namanzi. , imibala emine yokunyathelisa ngokweqile, ukunyathelisa ngombala wamabala, nokunye.Ukwakhiwa nokufakwa kukayinki wamanzi eShayina kwaqala sekwephuzile, kodwa inqubekelaphambili iye yashesha, ikakhulukazi eminyakeni yamuva nje, okuye kwahlanganisa izinga lokuthuthuka okusheshayo.Izinga likayinki wasekhaya lenyuke ngokuhambisana nokwanda kwesidingo sikayinki.Uyinki, ngokomqondo ovamile wokomisa ngendlela evilaphayo, ukucwebezela okungekuhle, ukuntula ukumelana namanzi, ukunyathelisa komgunyathi, namanye amaphutha, uye wathuthukiswa kakhulu.Amanani kayinki ongenisiwe ngokuvamile aphakeme kakhulu, kodwa uyinki waseShayina ubulokhu uthatha izintambo emakethe ngemiklamo yayo emihle futhi ethengekayo. Amanani kayinki ongenisiwe ngokuvamile aphakeme kakhulu, kodwa uyinki waseShayina ubulokhu uthatha izintambo emakethe ngemiklamo yayo emihle futhi ethengekayo.
Cabangela Izakhiwo Nokubunjwa Koyinki Osekelwe Emanzini.
Uyinki osuselwe emanzini wakhiwe inhlaka encibilika emanzini, izimibalabala eziyinkimbinkimbi, izincibilikisi, nezithasiselo eziye zacolwa ngokucutshungulwa kwenhlanganisela yesayensi.I-resin encibilika emanzini eyinki ngokuyinhloko isebenza njengento ehlanganisayo, ihlakaza izinhlayiya ze-pigment ngokufanayo ukuze uyinki ube nokuhamba okuthile futhi unamathele ku-substrate material ukuze uyinki akwazi ukwakha ungqimba lwefilimu olufanayo ngemva kokunyathelisa.Umbala kayinki unqunywa kakhulu i-pigment, ehlakazeka ngokulinganayo ekuxhumaneni njengezinhlayiya, futhi izinhlayiya ze-pigment zingakwazi ukumunca, zibonise, zihlehle, futhi zidlulise ukukhanya, zivumele ukuba zibonise umbala othize. i-pigment kumele ibe nombala ogqamile, umbala owanele namandla okuvala, nokuhlakazeka okuphezulu.Ngaphezu kwalokho, ngokuya ngokusetshenziswa, zingaba nokungazweli okuhlukahlukene kokuhuzuka.Umsebenzi we-solvent ukuncibilikisa inhlaka ukuze uyinki ube noketshezi oluthile, ukudluliswa kungenzeka kahle kuyo yonke inqubo yokunyathelisa, futhi ukusebenza kwe-viscosity nokomisa kukayinki kungashintshwa.I-solvent ku-inki esekelwe emanzini ngokuyinhloko ingamanzi ane-ethanol encane.
Uyinki Osuselwe Emanzini Uvamise Ukusebenzisa Izithasiselo Ezinjalo njenge-Defoamer, i-PH Value Stabilizer, i-Slow Drying Agent, nokunye nokunye.
(1) i-defoamer.Indima ye-defoamer ukuvimbela nokuqeda ukukhiqizwa kwamabhamuza omoya.Ngokuvamile, lapho i-viscosity ye-inki esekelwe emanzini iphezulu kakhulu, inani le-PH liphansi kakhulu, noma isivinini somshini wokuphrinta sishesha kakhulu, kulula ukukhiqiza amabhamuza.Uma inani lama-bubbles akhiqizwayo likhulu ngokuqhathaniswa, kuzoba nokuvuza kombala oyinki omhlophe, ongalingani, okuzothinta nakanjani ikhwalithi yendaba ephrintiwe.
(2) into eyomisa kancane.I-ejenti yokomisa kancane inganqanda futhi yehlise isivinini sokumisa sikayinki osekelwe emanzini ukuze kuvinjelwe uyinki epuleti lokuphrinta noma amarola e-anilox ukuthi ome kanye nokunciphisa izehlakalo zokuvimba nokunamathisela amaphutha wokuphrinta.Lawula inani le-ejenti yokomisa kancane;ngokuvamile, inani eliphelele likayinki kufanele libe phakathi kuka-1% no-2%.Uma ungeza kakhulu, uyinki ngeke wome kahle, futhi ukuphrinta kuzoba okunamathelayo, okungcolile, noma ukukhiqiza iphunga elibi.
(3) Isiqinisi senani le-PH:I-PH value stabilizer isetshenziselwa ngokuyinhloko ukulawula nokulawula inani le-PH likayinki osekelwe emanzini ukuze lizinze kububanzi obungu-8.0–9.5.Ngesikhathi esifanayo, ingakwazi futhi ukulawula i-viscosity ye-inki esekelwe emanzini kanye nokuhlanjululwa kweyinki.Ngokuvamile, inani elifanele le-PH stabilizer kufanele lengezwe njalo esikhathini esithile kunqubo yokuphrinta ukuze kugcinwe uyinki osuselwe emanzini usesimweni esihle sokuphrinta.
Ubungane bemvelo bukayinki osekelwe emanzini
Uyinki osuselwe emanzini uhlangabezana nezidingo zokuvikela imvelo, umkhiqizo unephunga elingenabuthi, elingagqwali, elingacasuli, awushi, awuqhumi, unokuvikeleka okuhle, kulula ukuthuthwa, unokugxila okuphezulu, okuphansi. umthamo, i-viscosity ephansi, ukuguquguquka okuhle kokuphrinta, ukusebenza okuzinzile, ukushesha okuhle kokubambelela, ukomisa ngokushesha, amanzi, i-alkali, nokusebenza kokumelana nemihuzuko kuhle kakhulu;Ukuphrinta amaphethini ayinkimbinkimbi kungase futhi kufinyelele amazinga acebile, imibala ekhanyayo necwebezelayo, nezinye izimfanelo.Inzuzo enkulu yokusebenzisa uyinki osekelwe emanzini ukuthi wehlisa inani le-organic volatiles (voc) elikhishelwa emkhathini, okusiza ukuthuthukisa izimo zokunyathelisa, gwema ukungcoliswa komoya, futhi wehlise kakhulu ingozi yomlilo.Ukuze kuthuthukiswe ikhwalithi evamile yendawo ezungezile, ingasusa ngokuphelele ezinye zezinto eziyingozi oyinki abasekelwe kuncibilikizo abanazo empilweni yomuntu, kanye nokungcola okuza nokupakishwa. Kusebenza kahle kakhulu ekuphrinteni nasekupakisheni izimpahla kudingeka zigcinwe zihlanzekile, njengokudla nemithi.
Njengomthengisi wenkomishi yephepha, i-GFP ibilokhu izibophezele ekusebenziseni izinto ezivumelana nemvelo ezimpahleni zayo, ibhekelele kokubili imvelo kanye nempilo yamakhasimende ayo.Izinkomishi zethu zephepha zinyatheliswa kusetshenziswa oyinki abasekelwe emanzini, futhi inqubo yokunyathelisa yenziwa ngaphambi kokuba izinkomishi zenziwe nge-laminated, ngakho-ke uma zisetshenziswa, uyinki ovela ngaphandle ngeke uguqe odongeni lwangaphakathi lwendebe, ivikele nakakhulu impilo. abasebenzisi.Sicela uvakashele isixhumanisi esilandelayo ukuze uthole okwengeziwe mayelana nezinkomishi zethu zephepha ezihambisana nemvelo kanye nezinhlelo zokusebenza ezihlobene.
