Indlela Yokuthuthukisa Ukunamathela kwe-Ink ye-UV?
Uma kukhulunywa ngokuphrinta kwe-UV, kungaphezu kokuthola imibala nokunemba kahle. Ukuhlola kwangempela kokuphrinta okuhle ukuthi ibambelela kahle kangakanani—ukuthi ingakwazi yini ukumelana nokungqubuzana, ukugoba, ukushisa, noma amanzi. Enye yezinselelo ezinkulu ekuphrinteni kwe-UV ukuthola ukuthi uyinki unamathele, ikakhulukazi ezintweni ezinamandla aphansi, njengamapulasitiki noma izinsimbi.
Lesi sihloko sichaza indlela yokuthuthukisa ukunamathela kweyinki ye-UV, ukubaluleka kokukhetha indawo efanelekile (noma i-substrate), kanye nendima yokwelapha kusengaphambili.
Isibonelo, qhathanisa indawo yepulasitiki eyenziwe ngomumo nebushelelezi ukuze uqonde umehluko wokubambelela.
I-polyethylene ne-polypropylene kukhonaamapulasitiki avamile anamandla aphansi angaphezulu; I-corona noma ukwelashwa kwe-flame kungasiza ukuthuthukisa ukunamathela kukayinki.
Hlola ukwakheka kukayinki okuhlukile endaweni encane ukuze uthole ukuvumelana okungcono kakhulu kwe-substrate yakho.
Isicelo esijwayelekile esoizinto zefilimu yepulasitiki emaphaketheni lapho ukwelashwa kwe-corona kuthuthukisa ukuphrinta kwendawo.
Cabangela ukusebenzisa i-etching primer ukuzethuthukisa ukunamathela kweyinki uma uphrinta ezinsimbi.
Qalisa ukuphrinta kokuhlola ngokuqina kwesibani okuhlukile ukuze uthole isikhathi esifanelekile sokuchayeka endaweni yakho ethile.
Uhlelo lokuhlanza lwamasonto onke lwamakhanda okuphrinta lunganciphisa kakhuluizindaba ezihlobene nokusabalalisa uyinki ngokungalingani noma ukunganamatheli.
Gcina irekhodi lemiphumela yakho yokuhlolwa, okuhlanganisa uhlobo lukayinki, ukwelashwa kwendawo, nezimo zemvelo, ukuze uthuthukise inqubo yakho yokuphrinta.
Bheka oyinki be-UV enzelwe indawo ethile, njengezinsimbi noma amapulasitiki, futhi uhlole imihlahlandlela yomkhiqizi ukuze uthole izimo ezingcono kakhulu zokusebenzisa.
Lungisa i-viscosity ye-inki ngokusekelwe ezimeni zakho zemvelo—ukushisa okufudumele kungase kudinge oyinki abathe ukushuba ukuze kuvinjelwe ukusabalala okukhulu.
Uma ubhekene nezinselelo ngendawo eshelelayo, hlola izithasiselo zikayinki ezidizayinelwe ukunamathela okuthuthukisiwe ezintweni ezicwebezelayo.
Emuva
Lesi sihloko sichaza indlela yokuthuthukisa ukunamathela kweyinki ye-UV, ukubaluleka kokukhetha indawo efanelekile (noma i-substrate), kanye nendima yokwelapha kusengaphambili.
Izinto Ezithinta I-UV Ink Adhesion
Kuyangcono ukunamathela kukayinki we-UV, kufanele uqale uqonde ukuthi yiziphi izici eziyithonya. Nazi izici ezibalulekile:I-Substrate Material
Uhlobo lwezinto ophrinta kuzo lunomthelela ekutheni uyinki unamathela kahle kangakanani. Ukwakheka komhlaba kuyahlukahluka phakathi kwezinto ezifana nepulasitiki, izinsimbi, nephepha. Isibonelo, ama-polymer acwebile nezinsimbi angeke zibambe uyinki noma izindawo ezimahhadlahhadla njengephepha. Ukwazi ukuthi indaba yakho isabela kanjani kukhoUyinki we-UV ikuvumela ukuthi wenze izinguquko ezifanele.Isibonelo, qhathanisa indawo yepulasitiki eyenziwe ngomumo nebushelelezi ukuze uqonde umehluko wokubambelela.
Amandla Angaphezulu
Amandla angaphezulu akala ukuthi ibhondi yendawo ephathekayo ihlangana kanjani noyinki. Izinto ezinamandla aphansi angaphezulu, njengamapulasitiki athile, ziyawenqaba uyinki. Ukwelashwa kwangaphambili kungakhuphula amandla angaphezulu, okuvumela ukuthi uyinki unamathele kangcono.I-polyethylene ne-polypropylene kukhonaamapulasitiki avamile anamandla aphansi angaphezulu; I-corona noma ukwelashwa kwe-flame kungasiza ukuthuthukisa ukunamathela kukayinki.
Ukubunjwa kukayinki
Ukwakheka kweyinki ye-UV nakho kunomthelela ekubambeleleni. Abanye o-ink bangase bashube kakhulu noma bome ngokushesha, okwenza kube nzima ukunamathela phezulu. Ukuthola ibhalansi efanele ku-ukwakheka kukayinki ikwenza inamathele phezulu.Hlola ukwakheka kukayinki okuhlukile endaweni encane ukuze uthole ukuvumelana okungcono kakhulu kwe-substrate yakho.
Surface Izindlela Zokwelapha Ngaphambili
Ukunamathela okuhle kudinga ukulungiswa okufanele kwendawo ngaphambi kokuphrinta. Nazi ezinyeamasu adumile okulungisa indawo yakho:Ukwelashwa KweCorona
Ukwelashwa kweCorona isebenzisa ukukhishwa kukagesi okune-voltage ephezulu ukukhulisa amandla angaphezulu wezinto ezinjengama-polymers. Kwenza indawo engaphezulu "imanzise," ivumela uyinki ukuthi unamathele kangcono.Isicelo esijwayelekile esoizinto zefilimu yepulasitiki emaphaketheni lapho ukwelashwa kwe-corona kuthuthukisa ukuphrinta kwendawo.
Ukwelashwa Kwe-Plasma
Ukwelashwa kwe-Plasma kushintsha indawo yezinto kusetshenziswa igesi ethile. Le ndlela yenza kube lula ukuthi uyinki we-UV ubambelele, futhi inenzuzo ezintweni okunzima ukuphrinta kuzo. Ukwelashwa kwe-Plasma kuzuzisa ama-substrates afana nengilazi noma izitsha zobumba, lapho izindlela zendabuko zingase zingasebenzi kahle.I-Chemical Priming
Usebenzisa ikhemikhali yokuqala noma ethile ngaphambiliizinsiza zokunyathelisa inki adhesion. Iziqalo ziqinisa isibopho phakathi kukayinki nongaphezulu, okuthuthukisa ukunamathela. Khetha i-primer ehambisana nakho kokubili i-substrate yakho noyinki.Cabangela ukusebenzisa i-etching primer ukuzethuthukisa ukunamathela kweyinki uma uphrinta ezinsimbi.
Indlela Yokuthuthukisa Ukunamathela kwe-Ink ye-UV?
Nansi indlela ongathuthukisa ngayo ukunamathela kweyinki ye-UV:Lungisa Izilungiselelo Zokuphrinta
Izilungiselelo zephrinta yakho zingathinta kakhulu ukubambelela kwe-inki. Qinisekisa ukuthi izibani ze-UV zephrinta yakho zisethelwe kumandla afanele kanye nesikhathi sokuchayeka. Ukwelashwa okufanele kuqinisekisa ukuthi uyinki unamathela ngempumelelo futhi yome ngendlela efanele.Qalisa ukuphrinta kokuhlola ngokuqina kwesibani okuhlukile ukuze uthole isikhathi esifanelekile sokuchayeka endaweni yakho ethile.
Gcina Impahla Yakho
Ukugcina okwakhoimishini yokunyathelisa ukuhlanzeka nokusebenza kahle kubalulekile. Izinto ezingcolile noma ezigugile, njengamarola namakhanda okuphrinta, zinomthelela ekufakweni kwe-inki nokubambelela. Ukunakekelwa okuvamile kusiza ukugwema lokhu kukhathazeka.Uhlelo lokuhlanza lwamasonto onke lwamakhanda okuphrinta lunganciphisa kakhuluizindaba ezihlobene nokusabalalisa uyinki ngokungalingani noma ukunganamatheli.
Hlola futhi Linganisa
Ngaphambi kokuphrinta iqoqo elikhulu, hlola izinto ezihlukile nezinhlobo zikayinki ukuze uthole inhlanganisela engcono kakhulu. Hlola amaphrinti akho okuhlola njalo ukuze uqinisekise ukuthi uyinki unamathela kahle. Ngale ndlela, ungenza izinguquko ngaphambi kokuqala iphrojekthi enkulu.Gcina irekhodi lemiphumela yakho yokuhlolwa, okuhlanganisa uhlobo lukayinki, ukwelashwa kwendawo, nezimo zemvelo, ukuze uthuthukise inqubo yakho yokuphrinta.
Ukukhetha Uyinki Nokuthuthukisa
Ukukhetha uyinki olungile futhi ukuyilungisa ukuze isebenze kangcono kubalulekile ekunamatheleni okuhle:Khetha Iziyinki ze-UV ezisezingeni eliphezulu
Ukutshala imali kumayinki e-UV aklanyelwe ngokusobala izinto ozisebenzisayo kubalulekile.Oyinki bekhwalithi ephezulu ngokuvamile inikeza ukunamathela okuphezulu, ukuqina, nokuvumelana kombala. Gwema ukusebenzisa oyinki abajwayelekile, okungenzeka bangasebenzi kahle.Bheka oyinki be-UV enzelwe indawo ethile, njengezinsimbi noma amapulasitiki, futhi uhlole imihlahlandlela yomkhiqizi ukuze uthole izimo ezingcono kakhulu zokusebenzisa.
Lungisa I-Viscosity ye-Ink
Ugqinsi lukayinki (olwaziwa ngokuthi i-viscosity) lunquma ukuthi unamathela ngempumelelo kangakanani. Qinisekisa ukuthi uyinki wakho awuwugqinsi kakhulu futhi awumncane kakhulu. I-viscosity efanele ithuthukisa ukunamathela kukayinki futhi ibangele ukuphrinta okushelelayo.Lungisa i-viscosity ye-inki ngokusekelwe ezimeni zakho zemvelo—ukushisa okufudumele kungase kudinge oyinki abathe ukushuba ukuze kuvinjelwe ukusabalala okukhulu.
Cabangela Izithasiselo Ze-Ink
Abanye oyinki be-UV banezithako ezithile ezikhuthaza ukubambelela. Lawa makhemikhali asiza ukuthi uyinki unamathele kangcono ezindaweni eziyinkimbinkimbi. Ukuzama ukwakheka kweyinki okuningana kungakusiza ukuthi uthole elungele izidingo zakho.Uma ubhekene nezinselelo ngendawo eshelelayo, hlola izithasiselo zikayinki ezidizayinelwe ukunamathela okuthuthukisiwe ezintweni ezicwebezelayo.
