Uma usebenzisa iphrinta ye-flatbed ye-UV ukuze uphrinte ezinye izinto, ngenxa yokomiswa ngokushesha kukayinki we-UV, kwesinye isikhathi kuholela enkingeni yokunamathela okuphansi kweyinki ye-UV ku-substrate.Lesi sihloko esokufunda indlela yokuthuthukisa ukunamathela kweyinki ye-UV ku-substrate.
ukwelashwa kwe-corona
Umbhali uthole ukuthi ukwelashwa kwe-corona kuyindlela engathuthukisa ngempumelelo ukunamathela kweyinki ye-UV!Ama-electrode aqondile noma angalungile edivayisi ye-corona asekelwe endizeni ephansi kanye nombhobho womoya we-Yuden ngokulandelanayo.Ama-electron amahhala anamandla aphezulu asheshiselwa ku-electrode eqondile, engashintsha i-polarity yezinto ezingamuncwa futhi andise ukuhwashala kwendawo, athuthukise ikhono lokuhlanganisa uyinki, afinyelele ukunamathela okuyinki kwe-UV okulungile, futhi athuthukise ukunamathela. ukushesha kongqimba lweyinki..
Izinto ezilashwe yi-Corona zinokuzinza okungahambi kahle kwendawo, futhi umphumela we-corona uzoba buthaka ngokuhamba kwesikhathi.Ikakhulukazi endaweni enomswakama ophezulu, umphumela we-corona uzoba buthaka ngokushesha.Uma kusetshenziswa ama-substrates afakwe ngaphansi kwe-corona, ukubambisana nomphakeli kufanele kwenziwe ukuze kuqinisekiswe ukusha kwama-substrate.Izinto ezijwayelekile zokwelashwa kwe-corona zifaka i-PE, i-PP, inayiloni, i-PVC, i-PET, njll.
Umgqugquzeli wokunamathela kweyinki we-UV (AdhesionPromoters)
Ezimweni eziningi, ukuhlanza i-substrate ngotshwala kuzothuthukisa ukunamathela kweyinki ye-UV ku-substrate.Uma ukunamathela kwe-substrate kuyinki ye-UV kukubi kakhulu, noma umkhiqizo unezidingo eziphezulu zokunamathela kukayinki we-UV, ungacabangela ukusebenzisa umgqugquzeli wokunamathela we-ink we-UV okhuthaza ukunamathela kukayinki we-UV.
Ngemuva kokuthi i-primer isetshenziswe ku-substrate engamuncwa, ukunamathela kweyinki ye-UV kungathuthukiswa ukuze kuzuzwe umphumela ofanele wokunamathela.Ngokuhlukile ekwelashweni kwe-corona, impahla ye-primer yamakhemikhali ayiqukethe ama-molecule e-non-polar oily, angaqeda ngokuphumelelayo inkinga yomphumela we-corona ongazinzile obangelwa ukufuduka kwama-molecule anjalo.Kodwa-ke, ububanzi bokusetshenziswa kwe-primer buyakhetha, futhi busebenza kangcono engilazini, i-ceramic, insimbi, i-acrylic, i-PET namanye ama-substrates.
Idigri yokwelapha eyinki ye-UV
Ngokuvamile, singakwazi ukubona ukunamathela okubi kwamayinki e-UV kuma-substrates angamumuki ezimeni lapho ama-ink e-UV engelapheki ngokugcwele.Ukuze uthuthukise izinga lokuphulukisa likayinki we-UV, ungaqala kulezi zici ezilandelayo:
1) Khulisa amandla esibani se-UV sokuphulukisa.
2) Yehlisa isivinini sokuphrinta.
3) Nweba isikhathi sokuphulukisa.
4) Hlola ukuthi isibani se-UV kanye nezinsiza zaso zisebenza kahle yini.
5) Yehlisa ubukhulu bongqimba lweyinki.
Ezinye izindlela
Ukushisisa: Embonini yokuphrinta isikrini, kuyanconywa ukushisisa i-substrate ngaphambi kokwelashwa kwe-UV ngaphambi kokuphrinta kuma-substrate okunzima ukunamathela.Ukunamathela koyinki be-UV kuma-substrates kungathuthukiswa ngemva kokushisisa ngokukhanya okuseduze kwe-infrared noma okukude kwe-infrared imizuzwana engu-15-90.
I-Varnish: Uma uyinki ye-UV isenenkinga yokunamathela ku-substrate ngemva kokusebenzisa iziphakamiso ezingenhla, i-varnish evikelayo ingasetshenziswa ebusweni bokuphrinta.
