Kuyini ukuphrinta kwefomethi ebanzi ye-UV?
Ijubane, ukuqina, nokuxazulula okuphezulu kwamaphrinta enziwe endaweni ebanzi kuguqule imboni yokunyathelisa emhlabeni wonke ngokusungulwa kokuphrinta kwefomethi ebanzi. Ngokungafani nokuphrinta kwe-solvent noma i-latex, ukuphrinta kwefomethi ebanzi ye-UV kusebenzisa ukusetshenziswa kokukhanya kwe-ultraviolet (UV) ukwenza lukhuni inki ngokushesha emidini ehlukene, kubangele inqubo yokomisa ngokushesha, imibala egqamile, nokuqina kwendawo evelele. Ngaphansi kwale nqubo eqhubekayo, ama-inks aqukethe i-UV aqukethe i-UV angaphansi kwezibani ze-UV LED noma izibani ze-mercury futhi akhiqizwa ukuze aguqule inkinobho ewuketshezi ibe yifilimu eqinile. Amaphrinta we-UV wefomethi ebanzi ayonga amandla, anobungani bemvelo, futhi ayaguquguquka kakhulu ekusetshenzisweni embonini ngokucindezela ukusetshenziswa kwezinhlelo zokomisa ezisuselwa ekushiseni.
Working Principle
Ukuphrinta kwefomethi ebanzi ye-UV kusekelwe ekuphenduleni kwe-photochemical okubizwa ngokuthi i-photopolymerization. Ama-monomers nama-oligomers kuma-inks aphulukkayo e-UV (i-CMYK + emhlophe ne-varnish) asesimweni soketshezi lapho efakwa ku-substrate, bese eqina lapho evezwa ku-wavelength ethile ye-UV, imvamisa i-365nm, 385nm, 395nm, noma i-405nm.
Izikhukhula ze-UV, izikhukhula ze-UV, noma isibani sokuphulukisa se-UV LED. Uhlelo lwezikhukhula ze-UV lukhiqiza ukukhanya kwe-ultraviolet, okuboniswa kuma-photoinitiators ku-inki ukudala ukusabela okuxhumanisayo. Lokhu kwenza ama-molecule e-inki a-polymerize ngokushesha, adale isithombe esiqinile, esingamelana nokuklwebha futhi esimelana nokufiphala ebusweni.
Izingxenye eziyinhloko zobuchwepheshe:
- I-UV LED Yokuphulukisa Ama-Wavelengths: 365-405nm
- Ukuqina kwe-UV (irradiance): 6-12 W / cm2
- Isinqumo sokuphrinta: 2400 dpi (esiphezulu, kuye ngohlobo lwekhanda)
- Ubuchwepheshe bekhanda lokuphrinta: I-Piezoelectric (i-Ricoh, i-Kyocera, i-Konica Minolta)
- Amandla okunamathela ku-inki: Insimbi, ingilazi, izinkuni, namapulasitiki.
- Ubuchwepheshe be-UV LED obusheshayo: Iqinisekisa ukwelashwa okuzinzile ngaphandle kokushisa.
Le ndlela ivumela ukomisa ukuthi kwenzeke ngokushesha, ukuze kuqhutshwe ngokuqhubekayo ngaphandle kokuma ukuvumela ukuhwamuka noma ukutholwa kwamakhemikhali, njengoba kubalulekile ekuphrintiseni okusheshayo kwe-UV inkjet
Izinzuzo zobuchwepheshe ze-UV LED Wide-Format Printing Systems
Ukuphrinta kwefomethi enkulu ye-UV ngobuchwepheshe be-UV LED kunezinzuzo eziningana zobunjiniyela bayo kanye nemvelo:
Ukusebenza kahle kwamandla okuphezulu
I-UV LED uhlelo lokuguqulwa kwemisebe kagesi kuya ku-ultraviolet olukhiqiza imisebe ye-ultraviolet ngokukhiqizwa okuphansi kokushisa. Azidingi amandla amaningi njengamalambu e-mercury, ngakho-ke, izibani kanye nama-substrates ahlala isikhathi eside.
Ukulondolozwa kwamandla: amaphesenti angama-70 wezinhlelo zokuphulukisa zendabuko.
Ukuminyana kwamandla: 6-12 W / cm2 kanye ne-irradiance engaguquki.
Ukuqala okusheshayo nokupholisa
Amamojula we-UV wokuphulukisa asekelwe ku-LED anokusebenza okusheshayo, okungukuthi, akudingeki ukufudumala. Lokhu kuthuthukisa ukukhiqizwa futhi kunciphise isikhathi sokungasebenzi emishinini yokuphrinta ye-UV yezimboni.
Ukulinganisa ukunemba nokukhanya kwesithombe
Izinhlelo zanamuhlazokuphulukisa izikhukhula ze-UV LED zinikeza ngisho nokusatshalaliswa kwe-irradiances kulo lonke indawo yokuphulukisa. Ama-substrates amakhulu aqinisekisa ukuvezwa okufanayo nokufana okuphezulu kokuphulukiswa ngenxa ye-lens array ebonakalayo nezilinganiso ezilinganisiwe zokuqhuma okukhazimulayo.
Impilo ebanzi kanye nensizakalo encane
Impilo yezibani ze-UV ze-LED ngokuvamile ingaphezu kwamahora angama-20,000, inikeza ukusebenza okuzinzile nezindleko eziphansi zokusebenza. Nazo azinayo i-mercury futhi zidinga ukugcinwa okuncane, okuhambisana nezinhloso zokusimama ekukhiqizeni okuhlakaniphile.
Izicelo
Ukusetshenziswa kwezinhlelo zokuphrinta ze-UV ezibanzi ezimbonini ezahlukahlukene kuvame kakhulu ngoba ziyaguquguquka futhi zingasetshenziswa kuzo zombili izinto eziqinile neziguquguqukayo.
Bonisa ihluzo nezimpawu
Okusetshenziswa kakhulu ekukhiqizeni amabhanela, amabhodi ezikhangiso, nemibukiso ye-POP. Lezi zimpawu nazo zinesimo sezulu esivelele nokumelana nokuklwebha ngama-inks aphulukiswe yi-UV, lapho umbala ugcinwa uzinzile ngisho nasezimweni zezulu ezinzima ezibonakala ngemisebe ye-UV ngokweqile.
Izicelo zezimboni nezakhiwo
Ukuphrinta kwe-UV engilazini, izinkuni, nensimbi kungasetshenziselwa ukuhlobisa izindawo kumaphaneli wokwakha, ifenisha, nangaphakathi lemoto, futhi kuhlala isikhathi eside. Iphrinta enkulu ye-UV LED iqinisekisa ukunemba okuphezulu kokunamathela kweyinki nokuxuba umbala obubushelelezi ezintweni eziyinkimbinkimbi.
Ukukhiqizwa kwe-Electronics ne-PCB
Ukuphrinta kwe-UV ye-elekthronikhi kungasetshenziselwa ukulebula, ukuvikela ukuhlanganiswa nokugqoka i-PCB ngokunembile. Ukucindezeleka okushisayo ezingxenyeni ze-elekthronikhi kususwa yinqubo ye-UV yokuphulukisa esheshayo, evikela izingxenye ezibucayi.
Ukupakisha kanye ne-prototyping
Ukuphrinta kwefomethi ebanzi ye-UV kusetshenziswa emaphaketheni ama-prototypes amafushane nemiklamo yokuhlobisa. Ngaphakathi kwenqubo yokuphulukisa indawo ye-UV LED, imiphumela egqamile, engenaphunga, futhi enobungani bemvelo iqinisekisiwe, ekahle emaphaketheni asezingeni lokudla.
I-Carmobile ne-3D.
Ubuchwepheshe buyasebenza nasekunyatheliseni kwe-UV kwezingxenye zezimoto nezindawo ze-3D ngokusetshenziswa kokuphrinta kwe-3D ukuhlinzeka ngokunamathela okuphezulu nokuqeda kuma-geometri agobile noma angajwayelekile.
The UV LED System 650x20 mm UVET Ukunyathelisa
I-UVET inikeza i-state-of-the-art UV LED System Printing (650x20 mm) ku-UVNDT ukusiza ekwelapheni kwefomethi ebanzi ye-UV. Uhlelo lunikeza ukuqina kwe-UV okufinyelela ku-12W / cm2, okwenza kube okusheshayo futhi kuphulukiswe ngokulinganayo endaweni enkulu yokumboza.
Izici ezibalulekile:
Ukusebenza okuhle kokuphulukisa: Ukuqina kwe-UV okuphezulu njenge-12W / cm2 ukuphulukisa ngokushesha.

Uhlelo lokuphulukisa indawo ye-UV LED futhi luyisandiso esingenamthungo samaphrinta edijithali, isikrini, kanye ne-ink jet, ahlinzeka ngokuqina kwekhwalithi yezimboni nokuphulukiswa ngezikhathi ezithile.
Umthelela Wezemvelo Nezomnotho
Ukuphrinta kwe-UV kuyatholakala ngefomethi ebanzi, enezinzuzo eziphezulu zemvelo. Ama-inki e-UV aqinile ngamaphesenti ayi-100 futhi awanawo ama-VOC, okusho ukuthi awakhiphi ama-solvents emoyeni, ngaleyo ndlela anciphise ukukhishwa kobuthi. Ngaphezu kwalokho, ukusetshenziswa kwamandla kwezinhlelo ze-UV ze-LED kuphansi, imfucuza incane, futhi akukho ukuhlunga kwe-ozone okudingekayo, okuyisixazululo esiluhlaza senqubo yamanje yokukhiqiza.
Ngokwezomnotho, umjikelezo wempilo ende wama-UV LED nezindleko eziphansi zezinto ezisetshenziswayo kuholela ezindlekweni eziphansi zobunikazi (TCO). Ngaphezu kwalokho, ukwelashwa okusheshayo kunciphisa isikhathi sokujika, okwenza imisebenzi isebenze kakhudlwana.
Isiphetho
Ukuphrinta kwefomethi ebanzi ye-UV kungenye yezinto ezithuthukile kwezobuchwepheshe bokuphrinta kwezimboni - ukunemba, ukusebenza, nokusimama. Lobu buchwepheshe buvuselela izindinganiso zokuphrinta kwanamuhla ngefomethi yayo yokuphulukisa ngokushesha, ukusebenza kahle kwamandla, nokuhambisana nezinhlobonhlobo zezinto zokwakha. Isibonelo esihle salokhu kuthuthukiswa yi-UVET 650x20 mm UV LED System of Printing, enokuqina okuphezulu kwe-UV, ukumbozwa kobubanzi be-wavelength, kanye nokuphulukiswa okuthembekile kokuphulukisa. I-UVNDT inganikeza ubuchwepheshe nobuchwepheshe obudingekayo ukuqhubekisela phambili ukukhiqizwa kwakho, njengoba abakhiqizi benentshisekelo ekusebenzeni okuphezulu, izixazululo zokuphrinta ze-UV ezinobungani bemvelo.
