Ukwelapha nge-UV ekuphrinteni kwedijithali kanye ne-inkjet
Ukwelashwa kwe-UV ubuchwepheshe sebuyindlela eyinhloko yokunyathelisa ngedijithali nange-inkjet, kusetshenziswa izimiso ze-photopolymerization ukuze kunqotshwe imikhawulo yokunyathelisa yendabuko. Indlela yayo eyinhloko ihilela ukukhanyiswa okusheshayo (imizuzwana engu-0.1) kokukhanya kwe-UV kuma-inki e-UV afakwe yi-inkjet aqukethe ama-photoinitiator, okufeza ukuphiliswa okusheshayo ngaphandle kokumuncwa kwe-substrate.
1. Izinhlelo Zokuphrinta Zedijithali
Ukuguquguquka Kwezinto Ezisetshenziswayo: Ukwelapha i-UV kwenza ukuphrinta okuzinzile ezindaweni ezingamunci (isb., ipulasitiki, insimbi, ingilazi), kwephula imingcele yendabuko ekhawulelwe ephepheni.
Ukuthuthukiswa Kwekhwalithi: Amaphethini alungisiwe abonisa ukugcwala kombala okuphezulu, ukucwebezela okuhlala isikhathi eside, kanye nokumelana nokuklwebheka okuphezulu, ahlangabezana nezidingo zokupakisha okuphezulu kanye namalebula ezimboni.
Ukuzivumelanisa Nezimo Kwamaqoqo Amancane: Kulungele ukukhiqizwa komuntu siqu kanye nesikhathi esifushane, kusekela ukwenziwa kweprototype okusheshayo kanye nokwenza ngezifiso uma kudingeka.
2. Intuthuko Yokuphrinta I-Inkjet
Ukuvimbela Ukungcola: Uyinki we-UV uyaphola ngokushesha lapho ufakwa, ususa ukugcotshwa ngesikhathi sokukhiqiza ngesivinini esikhulu futhi uvumele ukuphrinta okuqhubekayo.
I-UV ye-LED Ukuphakama: Imithombo yokukhanya ye-UV ye-LED yesimanje inciphisa ukusetshenziswa kwamandla ngo-70–80% uma kuqhathaniswa nezibani ze-mercury, ikhiqiza ukushisa okuncane, futhi ivumela ukuphrinta okuphephile ezintweni ezizwela ukushisa (isib. ama-PET, amafilimu).
Ukuhambisana Nemvelo: Ukusebenza okungenazo i-mercury kuhambisana nemithethonqubo yomhlaba wonke yezidakamizwa eziyingozi (isb., i-RoHS).
3. Izinzuzo Zekhwalithi Nokuzinza
Imiphumela Yomphezulu: Ukulungisa amandla e-UV kulawula amazinga acwebezelayo, kuyilapho uyinki okhethekile udala ukuqedwa okuthintekayo (isb., okumboziwe, okungacwebezeli).
Ama-VOC angekho: Ukwelashwa kwe-UV akukhiphi amakhemikhali e-organic aguquguqukayo, okuhambisana nezindinganiso ze-EU REACH kanye nezindinganiso zemvelo zomhlaba wonke.
Izinzuzo Zokusebenza Kahle: Ukwamukelwa kwe-UV ye-LED kwandisa umkhiqizo kanye nokusimama, kunciphisa izindleko zokusebenza ngo-40-60% ekuphathweni kwamandla kanye nemfucuza.
4. Ukuqinisekiswa Kwemakethe
Ukubikezela Kokukhula: Imakethe ye-inki ye-UV yaseShayina kulindeleke ukuthi ifinyelele ku-CNY eyizigidigidi ezingu-48 ngo-2025, okubangelwa ukukhula kwaminyaka yonke okungu-20% kuma-photoinitiators asekelwe emanzini.
Ukwamukelwa Kwezimboni: Ngaphezu kwama-70% amaphrinta okupakisha abeka phambili ukukhanyiswa kwe-UV ngenxa yezinzuzo zayo ezimbili zemvelo nezomnotho.
