Izimpilo zethu zigcwele izinto eziningi ezinyathelisiwe, izingubo, omagazini, kanye nokupakishwa kwazo zonke izinhlobo. Njengabathengisi bokupakisha ukudla ngobuningi kanye nabathengi, sikhathazeke kakhulu ngokuthi hlobo luni lweyinki olunobungani nemvelo futhi olufaneleka kakhulu embonini yokupakisha ukudla. Kulesi sihloko, sizokwethula kuyinki enobungani nemvelo efaneleka kakhulu ekuphrinteni ukupakisha ukudla: iyinki esekelwe emanzini.
Umqondo Woyinki Osekelwe Emanzini
Kusetshenziswa inqubo yesayensi ukudala lokhu okubizwa ngokuthi uyinki osekelwe emanzini, okusebenzisa kakhulu amanzi njengesinyibilikisi. Uyinki osekelwe emanzini kanye nezinye izinkinobho zokunyathelisa azinawo umthelela omubi empilweni yomqhubi womshini wokunyathelisa uma kuqhathaniswa nezinyibilikisi zazo eziphilayo ezingashisi, ezinobuthi. Ukunyathelisa nakho kunobungani nemvelo. Uyinki awunazo nje kuphela izakhiwo ezingashisi, kodwa futhi ususa usongo olufihliwe lokuba luvuthe futhi luqhume endaweni yokunyathelisa, okuyinto ewusizo ekusebenzeni okuphephile. Vele, uyinki noyinki manje kunezinhlelo zokusebenza ezahlukahlukene: uyinki wokunyathelisa we-offset, uyinki wokunyathelisa we-flexographic, kanye noyinki wokunyathelisa we-gravure. EYurophu, eMelika, eJapane, nakwamanye amazwe athuthukile, uyinki uye wathatha indawo kayinki kancane kancane, kanye nokunyathelisa kwe-offset ngaphandle kwezinye izindlela zokunyathelisa zeyinki ezihlukile. E-United States, isibonelo, ama-95% eziprinti ze-flexographic kanye nama-80% eziprinti ze-gravure aqukethe uyinki.
Ngaphezu kokuvikelwa kwemvelo, isetshenziswa kabanzi emhlabeni we-inki yamanzi ngenxa yokusebenza kwayo okuphezulu: ukuzinza kombala we-inki, ukukhanya okuphezulu, amandla okufaka imibala aqinile, ipuleti elingaboli, ukunamathela okuqinile ngemva kokuphrinta, isivinini sokomisa esilungisekayo, ukumelana namanzi, ukuphrinta okungaphezu kwemibala emine, ukuphrinta okunemibala egqamile, njalo njalo. Ukuthuthukiswa nokusetshenziswa kwe-inki yamanzi eShayina kwaqala sekwephuzile, kodwa intuthuko ibe ngokushesha, ikakhulukazi eminyakeni yamuva nje, okwenze izinga lokuthuthukiswa okusheshayo landa. Ikhwalithi ye-inki yasekhaya ikhuphuke kanye nokwanda kwesidingo se-inki. I-inki, ngomqondo wendabuko wokomisa kancane, ukucwebezela okubi, ukuntuleka kokumelana namanzi, ukuphrinta okungeyikho, kanye nezinye iziphambeko, ithuthukiswe kakhulu. Amanani e-inki engenisiwe ngokuvamile aphezulu kakhulu, kodwa i-inki yaseShayina ibilokhu ithatha imakethe ngemiklamo yayo emihle nengabizi. Amanani e-inki engenisiwe ngokuvamile aphezulu kakhulu, kodwa i-inki yaseShayina ibilokhu ithatha imakethe ngemiklamo yayo emihle nengabizi.
Cabanga Ngezakhiwo Nokwakheka Kweyinki Esekelwe Emanzini.
Uyinki osekelwe emanzini wakhiwe yi-resin encibilika emanzini, ama-pigment ayinkimbinkimbi, izinyibilikisi, kanye nezithasiselo eziye zagaywa ngokucubungula okuhlanganisiwe kwesayensi. I-resin encibilika emanzini kuyinki isebenza ngokuyinhloko njengento exhumanisayo, ihlakaza izinhlayiya ze-pigment ngokulinganayo ukuze uyinki ibe nokuhamba okuthile futhi inamathele ezintweni ezingaphansi komhlaba ukuze uyinki yakhe ungqimba lwefilimu olufanayo ngemva kokuphrinta. Umbala weyinki unqunywa kakhulu yi-pigment, ehlakazeka ngokulinganayo ezintweni ezixhumanisayo njengezinhlayiya, futhi izinhlayiya ze-pigment zingamunca, zibonakalise, ziphinde zidlulise ukukhanya, zivumele ukuthi zibonise umbala othize. Ngokuvamile, i-pigment kumele ibe nombala ocacile, umbala owanele kanye namandla okumboza, kanye nokusabalala okuphezulu. Ngaphezu kwalokho, kuye ngokusetshenziswa, ingaba nokumelana okuhlukahlukene kokuguguleka. Umsebenzi we-solvent ukuncibilikisa i-resin ukuze uyinki ibe nokugeleza okuthile, ukudluliselwa kungenzeka kahle kuyo yonke inqubo yokuphrinta, futhi ukusebenza kwe-viscosity nokomisa kweyinki kungashintshwa. I-solvent kuyinki osekelwe emanzini ngokuyinhloko amanzi ane-ethanol encane.
Uyinki Osekelwe Emanzini Uvame Ukusebenzisa Izithasiselo Ezinjalo njenge-Defoamer, i-PH Value Stabilizer, i-Slow Drinking Agent, njalo njalo.
(1) umshini wokuhlanza izicubu. Indima ye-defoamer ukuvimbela nokuqeda ukukhiqizwa kwama-bubble omoya. Ngokuvamile, lapho i-viscosity ye-inki esekwe emanzini iphezulu kakhulu, inani le-PH liphansi kakhulu, noma ijubane lokusebenza komshini wokuphrinta lishesha kakhulu, kulula ukukhiqiza ama-bubble. Uma inani lama-bubble akhiqizwayo likhulu kakhulu, kuzoba nokuvuza kombala we-inki omhlophe, ongalingani, okuzothinta ngokungenakugwenywa ikhwalithi yento ephrintiwe.
(2) into yokomisa kancane.I-ejenti yokomisa kancane ingavimbela futhi yehlise ijubane lokomisa kwe-inki esekwe emanzini ukuvimbela i-inki epuletini lokuphrinta noma kuma-anilox rollers ukuthi yome futhi kuncishiswe ukwanda kwamaphutha okuphrinta okuvimbayo nokunamathisela. Lawula inani le-ejenti yokomisa kancane; ngokuvamile, inani eliphelele le-inki kufanele libe phakathi kuka-1% no-2%. Uma ufaka kakhulu, i-inki ngeke yome kahle, futhi okuphrintiwe kuzoba okunamathelayo, okungcolile, noma okukhiqizwe iphunga elibi.
(3) Isiqinisi senani le-PH:Isiqinisi senani le-PH sisetshenziswa kakhulu ukulawula nokulawula inani le-PH likayinki osekelwe emanzini ukuze lizinze ebangeni eliphakathi kuka-8.0–9.5. Ngesikhathi esifanayo, singalawula futhi ukujiya kweyinki osekelwe emanzini kanye nokuxutshwa kweyinki. Ngokuvamile, inani elifanele lesiqinisi se-PH kufanele lifakwe njalo ngesikhathi esithile enkambisweni yokuphrinta ukuze kugcinwe uyinki osekelwe emanzini usesimweni esihle sokuphrinta.
Ubungane bemvelo beyinki esuselwe emanzini
Uyinki osekelwe emanzini uhlangabezana nezidingo zokuvikela imvelo, umkhiqizo unephunga elingenabo ubuthi, aliboli, alicasuli, alishisi, aliqhumi, linokuphepha okuhle, kulula ukulithutha, linomthamo ophezulu, isilinganiso esiphansi, i-viscosity ephansi, liyakwazi ukuzivumelanisa kahle nokuphrinta, ukusebenza okuzinzile, ukushesha okuhle kokunamathela, ukomisa ngokushesha, ukusebenza kwamanzi, i-alkali, kanye nokumelana nokuklwebheka kuhle kakhulu; Amaphethini ayinkimbinkimbi okuphrinta angaphinde afinyelele amazinga acebile, imibala ekhanyayo nekhazimulayo, nezinye izimfanelo. Inzuzo eyinhloko yokusebenzisa uyinki osekelwe emanzini ukuthi wehlisa inani lezinto eziphilayo ezikhishwa emoyeni, okusiza ukuthuthukisa izimo zokuphrinta, ukugwema ukungcola komoya, kanye nokunciphisa kakhulu ingozi yomlilo. Ukuze kuthuthukiswe ikhwalithi evamile yendawo, kungasusa ngokuphelele ezinye zezinto eziyingozi ezinazo uyinki osekelwe ku-solvent empilweni yabantu, kanye nokungcola okuza nokupakishwa. Kusebenza kahle kakhulu ekuphrinteni nasekupakeni izimpahla ezidinga ukugcinwa zihlanzekile, njengokudla nemithi.
Njengomthengisi wendebe yephepha, i-GFP ibilokhu izibophezele ekusebenziseni izinto ezinobungani nemvelo ezimpahleni zayo, ithatha umthwalo wemfanelo kokubili imvelo kanye nempilo yamakhasimende ayo. Izindebe zethu zephepha zinyatheliswa kusetshenziswa uyinki osekelwe emanzini, futhi inqubo yokunyathelisa yenziwa ngaphambi kokuba izinkomishi zifakwe i-laminate, ngakho-ke uma zisetshenziswa, uyinki ovela ngaphandle ngeke uthinte udonga lwangaphakathi lwendebe, okuvikela impilo yabasebenzisi. Sicela uvakashele isixhumanisi esilandelayo ukuze uthole okwengeziwe mayelana nezindebe zethu zephepha ezinobungani nemvelo kanye nezinhlelo zokusebenza ezihlobene.
