Uyinki uyingxenye ebalulekile ezinqubweni ezahlukene zokuphrinta, futhi izinhlobo ezahlukene zoyinki zisetshenziselwa ukufeza imiphumela ethile. Uyinki we-eco-solvent, uyinki we-solvent, kanye noyinki osekelwe emanzini yizinhlobo ezintathu zoyinki ezivame ukusetshenziswa, ngayinye inezici zayo ezihlukile kanye nezinhlelo zokusebenza. Ake sihlole umehluko phakathi kwazo.
Uyinki osekelwe emanzini uyindlela etholakala kabanzi futhi enobungani nemvelo. Uqukethe imibala noma udayi oncibilikiswe emanzini. Lolu hlobo lweyinki alunabo ubuthi futhi luqukethe i-VOC ephansi (ama-organic compounds aguquguqukayo), okwenza luphephe ukusetshenziswa ezindaweni zangaphakathi. Uyinki osekelwe emanzini usetshenziswa kakhulu ekunyatheliseni ehhovisi, ekunyatheliseni ubuciko obuhle, ekunyatheliseni izindwangu nakwezinye izinhlelo zokusebenza.
Ngakolunye uhlangothi, uyinki we-solvent uqukethe imibala noma udayi oncibilikiswe kuma-organic compounds noma ama-petrochemicals aguquguqukayo. Lo uyinki uqinile kakhulu futhi unikeza ukunamathela okuhle kakhulu ezintweni ezahlukahlukene okuhlanganisa i-vinyl, ipulasitiki kanye nensimbi. Uyinki we-solvent uvame ukusetshenziswa ezimpawini zangaphandle kanye nezicelo zokugoqa izimoto ngoba umelana nezimo zezulu ezinzima futhi unikeza imiphumela yokunyathelisa ehlala isikhathi eside.
Uyinki we-eco-solvent uyinki omusha onezakhiwo phakathi koyinki osekelwe emanzini kanye noyinki we-solvent. Uqukethe izinhlayiya ze-pigment ezilengiswe ku-solvent enobungani nemvelo, equkethe ama-VOC aphansi kuneyinki ye-solvent yendabuko. Uyinki we-eco-solvent unikeza ukuqina okuthuthukisiwe kanye nokusebenza kwangaphandle ngenkathi ungabi yingozi kakhulu emvelweni. Uvame ukusetshenziswa ezinhlelweni zokusebenza ezifana nokuphrinta amabhanela, ihluzo ze-vinyl, kanye nezithombe zodonga.
Omunye wemimehluko emikhulu phakathi kwalezi zinhlobo zeyinki inqubo yokupholisa. Uyinki osekelwe emanzini uyoma ngokuhwamuka, kuyilapho uyinki osekelwe ku-solvent kanye noyinki oncibilikayo odinga isikhathi sokomisa ngosizo lokujikeleza kokushisa noma komoya. Lo mehluko enkambisweni yokupholisa uthinta isivinini sokuphrinta kanye nobuchwepheshe bemishini yokuphrinta.
Ngaphezu kwalokho, ukukhethwa kweyinki kuncike ezidingweni ezithile zephrojekthi yokuphrinta. Izici ezifana nokuhambisana kwendawo, ukusebenza kwangaphandle, ukukhanya kombala kanye nomthelela emvelweni zidlala indima ebalulekile ekukhetheni uhlobo lweyinki olufanele.
Sekukonke, uyinki osekelwe emanzini muhle kakhulu ekuphrinteni okunobungani nemvelo ngaphakathi endlini, kuyilapho uyinki we-solvent unikeza ukuqina kwezicelo zangaphandle. Uyinki we-solvent osebenzisa imvelo ulinganisa phakathi kokuqina kanye nezinkinga zemvelo. Ukuqonda umehluko phakathi kwalezi zinhlobo zoyinki kuvumela abaphrinta ukuthi benze izinqumo ezinolwazi ngokusekelwe ezidingweni zabo zokuphrinta ezithile kanye nezibopho zemvelo.
