Uhlelo lokuphulukisa lwe-UV LED lokuphrinta kwe-inkjet: Ukucatshangelwa Kokusetha

Ukusetha uhlelo lokuphulukisa lwe-UV LED lokuphrinta kwe-inkjet kudinga ukulinganisa izinto ezintathu ezibucayi: ukukhanya kwe-spectral, ukuphathwa okushisayo, nokuhlanganiswa komzimba. Ukusetha okuphumelelayo kuqinisekisa ukuthi ubude besibani se-UV LED (imvamisa i-395nm noma i-385nm) buhambisana nephrofayili ye-photoinitiator ye-inki ngenkathi kugcinwa "ibanga lokusebenza" okungaguquguquki (imvamisa i-2-10mm) kusuka ku-substrate. Ukunganaki lezi zinyathelo eziqondile zokulinganisa kuvame ukuholela ekuhlulekeni kokunamathela, i-tackiness, noma ukusonteka kwe-substrate. Lo mhlahlandlela uphula imininingwane ebalulekile yezobuchwepheshe kanye nezivumelwano zokufaka ukuze uthuthukise uhlelo lwakho ukuze uthole isivinini sokwelashwa esilungele ukukhiqizwa nokuqina.

Izidingo zokusetha: Amandla nokuqondanisa

Ukufeza i-polymerization esheshayo ngaphandle kokulimaza ama-substrates azwela ukushisa, ukufakwa kwakho kufanele kubhekane nokuqondanisa kwemishini nokuzinza kukagesi.

Amandla nokuzinza kukagesi

Izinhlelo ze-UV LED zizwela ekuguqukeni kwe-voltage. Ngokungafani nezibani ze-mercury arc ezithethelela kakhudlwana, ama-LED adinga ukunikezwa kwamandla okuzinzile kwe-DC. Qinisekisa ukuthi isikhungo sakho sihlinzeka ngesifunda esizinikezele nge-UPS (Uninterruptible Power Supply) ukuvimbela ama-voltage sags angadala ukuqina kokwelapha okungahambisani noma "i-banding" ekuphrintiweni kokugcina.

Ukuhlanganiswa kwemishini kanye nebanga lokusebenza

"Ibanga lokusebenza" - igebe phakathi kwewindi lokukhipha i-LED nendawo yeyinki - liyiphuzu elivame kakhulu lokwehluleka.

• Igebe elihle: Gcina ibanga eliphakathi kuka-2mm kuya ku-10mm.
• Kungani kubalulekile: Amandla e-LED ayashabalala ngokushesha kude. Ukwandisa igebe kusuka ku-5mm kuye ku-10mm kunganciphisa ukukhanya okuphezulu ngaphezu kuka-40%, okuholela ku-inki onamathelayo
.
• Ukuqondanisa: Isibani kufanele sifakwe ngokuqondile ekuqondisweni kokuhamba kwe-substrate ukuqinisekisa ukulethwa komthamo ofanayo kulo lonke ububanzi bokuphrinta.

Yini i-Wavelength engcono kakhulu ye-UV LED Curing?

Ubude obuhle kakhulu buncike ngokuphelele ekwakhiweni kweyinki yakho, kepha i-395nm iyindinganiso yomkhakha yezicelo eziningi ze-UV inkjet. Inikeza ibhalansi engcono kakhulu yokuphulukiswa kokujula nokumiswa komhlaba okungena-tack.

Ukuqonda i-Spectrum (365nm vs. 395nm)

• I-395nm: Ihhashi lokusebenza le-inkjet. Ingena kahle ngama-inks anemibala futhi isebenza kahle kakhulu ekuphrithelweni okujwayelekile kwemifanekiso.
• I-385nm: Imvamisa isetshenziselwa ama-varnishes acacile noma ama-adhesives lapho ufuna ukugwema umphumela "ophuzi" kwesinye isikhathi obangelwa ukuphulukiswa kwe-395nm.
• I-365nm: Inikeza amandla aphakeme kakhulu okuphulukisa okujulile (ukunamathela kuma-substrates anzima) kepha ayisebenzi kahle ngokuya ngokuguqulwa kwamandla kagesi-kuya ku-optical.

Cooling Systems: Air vs. Water

Ukuphathwa kokushisa kubalulekile hhayi ku-substrate (ngoba ama-LED "apholile"), kodwa kuma-diode e-LED uqobo. Ama-diode okushisa ngokweqile alahlekelwa ukuqina futhi ahluleka ngaphambi kwesikhathi.

Air-Cooled Systems

Kungcono ukuskena izishicileli noma izimiso ezincane.

• Izinzuzo: Ukufakwa okulula, akukho amapayipi adingekayo, izindleko zokuqala eziphansi.
• Ububi: Abalandeli be-bulky bangaphazamisa ukugeleza komoya eduze kwekhanda lokuphrinta (okubangela izinkinga ze-ink misting); ukukhishwa kwamandla okulinganiselwe.

Izinhlelo Ezipholile Amanzi

Okujwayelekile kokukhiqiza okusheshayo, ukukhiqizwa okukodwa okuphezulu.

• Izinzuzo: Amakhanda wesibani ahlangene (kulula ukufaka), ukusebenza buthule, kugcina ukuqina okuphezulu okuzinzile kwama-shifts amade.
• Ububi: Kudinga iyunithi ye-chiller kanye nokugcinwa kwamapayipi; ingozi yokufingqa uma amanzi ebanda kakhulu.

Ukuqhathanisa: Izindlela zokupholisa

Kungani inki yami ye-UV inamathela ngemuva kokwelashwa?

I-inki enamathelayo imvamisa ikhombisa ukuvinjelwa kwe-oksijini noma umthamo onganele wendawo. I-oksijini emoyeni ingavimba ukusabela kokuphulukisa ungqimba oluphezulu kakhulu lweyinki.

Ukubhekana ne-Oxygen Inhibition

Uma ubuso buhlala buqinile kepha isisekelo siqinile, uhlelo lwakho lwe-LED lungadinga ukuqina okuphezulu ukuze unqobe isithiyo se-oksijini. Ngenye indlela, qinisekisa ukuthi ukwakheka kwakho kweyinki kufaka phakathi ama-amine synergists asiza ukunciphisa ukuphazamiseka kwe-oksijini.

How Long Do UV LED Lamps?

Enye yezinzuzo eziyinhloko zokushintshela ku-LED isikhathi eside.

Isikhathi sokuphila esilindelekile

Uhlelo lwekhwalithi ye-UV LED ngokuvamile luhlala amahora angama-20,000 kuye kwangama-30,000 "ngesikhathi." Ngoba ama-LED afaka amandla okuvula / ukuvala okusheshayo, asebenza kuphela lapho ephrinta ngempela, ngokungafani nezibani ze-mercury ezisebenza ngokuqhubekayo. Lokhu kuvame ukuhumusha eminyakeni engu-5-10 yokuphila kwesevisi endaweni ejwayelekile yokukhiqiza, ukunciphisa kakhulu isikhathi sokuphumula nezindleko zokufaka esikhundleni.

Imibuzo Evame Ukubuzwa

Ngingakwazi ukubuyisela kabusha iphrinta yami ye-UV ekhona ngezibani ze-LED?

Yebo, amaphrinta amaningi e-UV angafakwa kabusha. Kodwa-ke, kufanele uqinisekise ukuthi isethi yakho ye-inki "iyaphulukiswa." Ama-inks amadala e-UV aklanyelwe izibani ze-mercury kungenzeka angaphuluki kahle ngaphansi kwe-spectrum emincane ye-LED (395nm).

Ingabe izibani ze-UV LED zikhiqiza i-ozone?

Cha. Izibani ze-UV ze-LED azikhiphi imisebe ye-UV-C emfushane (ngaphansi kwe-280nm), enesibopho sokukhiqiza i-ozone. Lokhu kuqeda isidingo sokwenza i-ductwork yokukhipha ebizayo.

Ngilinganisa kanjani ukukhishwa kwe-UV LED?

Awukwazi ukusebenzisa i-radiometer ejwayelekile ye-UV eyenzelwe izibani ze-mercury. Kufanele usebenzise i-radiometer elinganiselwe ngokukhethekile i-LED spectra (imvamisa igxile ebangeni le-365nm-405nm) ukuthola ukufundwa okunembile.

Key Takeaways

• Fanisa i-Wavelength: Qinisekisa ukuthi isibani sakho (395nm / 385nm) sihambisana nama-photoinitiators we-inki wakho.
• Qaphela igebe: Gcina isibani esingu-2-10mm kusuka ku-substrate ukuvimbela ukulahleka kokuqina.
• Ukupholisa Izinto Zokupholisa: Khetha ukupholisa kwamanzi ngejubane eliphezulu, ukukhiqizwa okuqhubekayo; ukupholisa umoya ngezidingo ezingezikhathi ezithile noma ezisheshayo eziphansi.
• Hlola Amandla: Sebenzisa ukunikezwa okuzinzile kwe-DC ukuvimbela ukuphulukisa i-banding.

Isiphetho

Ukushintshela ohlelweni lokuphulukisa lwe-UV LED lokuphrinta kwe-inkjet kunikeza ukusebenza kahle kwamandla okuthuthukisiwe, ukushisa okuncishisiwe kuma-substrates, nezindleko eziphansi zesondlo. Kodwa-ke, uhlelo luhle kuphela njengokusetha kwalo. Ngokuphatha ngokuqinile ibanga lokusebenza, ukupholisa okushisayo, nokuzinza kwamandla, ungafinyelela ukwelashwa okungaguquguquki, okusezingeni eliphakeme okuhlangabezana nezidingo zokuphrinta kwezimboni zanamuhla.
