Izinzuzo kanye nokubi inki amanzi-based
Uyinki osuselwe emanzini, osebenza njengendlela emisha yokuphrinta, ugqama ngamandla awo awumongo wokungabandakanyi izinyibilikisi zemvelo eziguquguqukayo, wehlisa kakhulu ukukhishwa kwezinhlanganisela ze-organic (VOCs), futhi ngaleyo ndlela kungabikho monakalo kubakhiqizi beziyinki noma empilweni yabasebenzi, kanyekanye. ukuthuthukisa ikhwalithi yemvelo jikelele. Ilebulwe ngokuthi uyinki oyi-eco-friendly, izinzuzo zayo zemvelo ikakhulukazi ziwukuthi ayinabungozi emvelweni, ayinabo ubuthi kubantu, obungashi, futhi ivikeleke kakhulu, ehlisa ngempumelelo ubuthi obusalela ezintweni eziphrintiwe, izinqubo zokuhlanza zilula zemishini yokunyathelisa, kanye nokunciphisa. izingozi zomlilo ezixhunywe kugesi ongashintshi kanye nezincibilikisi ezivuthayo, ezakha impahla yokupakisha yangempela "eluhlaza".
Ngokwezici zokuphrinta, uyinki osuselwe emanzini ubonisa ukuzinza okuyingqayizivele, ukungagqwali kwamapuleti okuphrinta, ukusebenza kalula, ukufinyeleleka kalula, ukunamathela okuqinile ngemuva kokuphrinta, ukumelana kwamanzi aphezulu, kanye nesivinini sokoma esisheshayo (kufika kumamitha angama-200 ngomzuzu). ), isebenza kugravure, flexographic, kanye nokuphrinta kwesikrini okunamandla abanzi. Naphezu kokuhwamuka komswakama okuhamba kancane okudinga izinhlelo zokomisa ezishisayo kanye nokumanzisa okungaba khona okubangelwa umswakama, lezi zinkinga zixazululwe ngempumelelo ngentuthuko yezobuchwepheshe.
Ukwakheka kukayinki osuselwe emanzini kuhlanganisa ama-emulsions e-polymer atholakala emanzini, i-pigments, ama-surfactants, amanzi, nezinye izithasiselo ezengeziwe. Phakathi kwalokhu, ama-emulsions e-polymer aphuma emanzini, afana nokuphuma kwe-acrylic ne-ethylbenzene, asebenza njengabathwali be-pigment, anikeza ukunamathela, ukuqina, ukucwebezela, izinga lokumisa, ukumelana nokuhuzuka, nokumelana namanzi kuyinki, afanele kokubili ama-substrates angamuncwa futhi amunca. Izingulube zisukela kweziphilayo njenge-phthalocyanine eluhlaza okwesibhakabhaka kanye ne-lithol ebomvu kuya kwezingaphili njenge-carbon black ne-titanium dioxide. Ama-surfactants asiza ekwehliseni ukungezwani kwendawo, enze kube lula ukusatshalaliswa kukayinki ku-substrate, kanye nokuthuthukisa ukuzinza.
Noma kunjalo, izithiyo zikayinki osuselwe emanzini ngokuyinhloko zizungeza ukunamathela okuphansi, ukukhanya okuncane, kanye nezikhathi zokumisa kancane. Kodwa-ke, ngezinto ezintsha zobuchwepheshe ezifana nokulungiswa kwe-substrate okuthuthukisiwe, ukwakheka kombala okuthuthukisiwe, nezindlela zokuphrinta ezithuthukisiwe, lokhu kukhathazeka kwehle kakhulu, okwenza uyinki osuselwe emanzini uqhudelane kakhulu futhi, ezimweni eziningi, wedlula uyinki ovamile osekelwe ku-solvent ezinhlelweni ezisebenzayo. Nakuba uyinki osekelwe emanzini ufaka izindleko zempahla eluhlaza eziphakeme kancane, uma kubhekwa ubungane bayo bemvelo nokuvikelwa kwezempilo kubasebenzisi, izindleko ezengeziwe zithathwa njengokutshalwa kwezimali okuthethelelekayo.
