Izicelo Ezibalulekile Zokwelashwa Kwe-UV LED Ensimini Yokuphrinta Ngesivinini esikhulu/Ukuphrinta kwe-Offset

UV   LED   ukwelapha kuguqula o-inki, ama-coatings, izinto zokunamathisela, nezinye izinto ezisebenza isithombe zibe izinto eziqinile ezigxilile ngokushesha ngokusebenzisa i-polymerization kusetshenziswa ukukhanya okusebenzayo kwe-electron ultraviolet (UV). Ngokuphambene, "ukoma" kuqinisa i-chemistry ngokumuncwa noma ukuhwamuka.

Izinzuzo zayo zinkulu futhi zingalinganiswa ezinhlanganweni eziningi zokunyathelisa zesimanje, kusukela endaweni epholile, ehlanzekile ekhululayo kunaleyo ecwengisiswe ngezibani zokugoba zemercury ezivamile ngamasu avamile kuya emiphumeleni esheshayo nevamile, ukusebenza kahle, kanye nokuqoshwa kwemvelo okunciphile.

Ukuthatha isinyathelo esiqhubekayo, opharetha bangahlela amandla e-UV anembile adingekayo ukuze kushintshwe izidingo zenqubo yokunciphisa udoti womkhiqizo, kukhuliswe amandla okukhiphayo, nokusebenzisa imigqa yokukhiqiza ngempumelelo ngangokunokwenzeka. Ezinhlelweni ezinamayunithi amaningana, ukuvala amamojula athile ukonga ugesi ngaphandle kokuthinta inqubo yokukhiqiza noma ikhwalithi yomkhiqizo kungenzeka.

Ngabe i-UV ibuyisela kanjani umsebenzi?

Ukubuyisela i-UV umjikelezo wamakhemikhali wesithombe onciphile, osheshayo, ongancibilika oshintsha oyinki, ama-coatings, usimende, noma ezinye izinto eziphendula izithombe zibe izinto eziqinile ezilungiswa ngokushesha futhi zisethwe nge-polymerization kusetshenziswa ukukhanya okukhanyayo kagesi okuphezulu (UV). Kuyathakazelisa ukuthi "ukoma" kwenza isayensi ibe lukhuni ngokufana noma ngokunyamalala. Umphumela oncomekayo wokubuyiselwa kwe-UV owokuba izinto zokukhulula zibe nobukhulu obanele bokulungisa esikhundleni sokuba zibe shabby, ezintekenteke, noma ezintekenteke futhi zibambelele ngokuphephile endaweni ezibekwe kuyo.

Ukukhulula indawo, ukubuyisela izikhukhula, ukubuyisela okubanjwa ngesandla, nokubuyisela ezokuthutha kuyizinhlobo ezimbalwa zokukhulula i-UV. Izinhlaka zokubuyisela i-UV zisebenzisa izibani ezihlukene njengemithombo yokukhanya ye-UV, okuhlanganisa ama-diode akhiqiza ukukhanya (ama-LED), avele abe umphumela wemisebe ye-UVA, namalambu ejika asekelwe ku-mercury, anikeza ububanzi obubanzi bokukhanya kwe-UV. Ama-LED e-UVC ayabonakala, kodwa anemiphumela yamandla aphansi kakhulu kanye nokukhiqiza.

Izibani ze-Mercury circular segment (HG type) zisetshenziswa njalo njengezimpendulo zokubuyisela i-UV zokuphrinta neminye imijikelezo yesimanje. Sekuyisikhathi eside beyindinganiso yebhizinisi.

Bane-downsides kunoma yisiphi isenzakalo lapho bekwazi kahle. Indlela abakhiqiza ngayo ithoni yokuqina futhi basebenzise amandla amaningi iyona ebaluleke kakhulu. Ngaphezu kwalokho, bakhiqiza ama-mercury curve bulbs, athinta isimo sezulu futhi kufanele alahlwe ngezindleko nangaphansi kokuhlolwa kokuphatha. Aphinde abangele i-oxidation, edinga izinhlaka zokukhipha umoya ukuze kuvikelwe ikhwalithi yomoya.

Zonke izinzuzo zokukhululwa kwe-UV okujwayelekile kwethulwa ukubuyisela i-UV okusekelwe ku-Drove, okuphinde kubhekane nenani elibalulekile lezinkinga ngokomisa okusethiwe ukushisa. Ukuvula/ukuvala ngokushesha, ukomisa/ukubuyisela okushesha nokuthembekile, imiphumela enomfutho ophansi, kanye nokusetshenziswa kwamandla aphansi ngezinye zakho. Ngaphezu kwalokho, usayizi wesakhiwo se-Drove UV uphishekela isinqumo esingcono kakhulu sokujoyina amasistimu noma amagiya anendawo ekhawulelwe.

Ikhambi Elihlanzekile, Elipholile

azikhiqizi ukushisa kwe-infrared futhi zisebenza emazingeni okushisa aphansi kakhulu kunezibani ezivamile ze-mercury arc I-Ultraviolet yokwelapha izibani, amasistimu okwelapha ama-UV e-LED anenzuzo yokugwema izingozi ezihlobene nokushisa kanye nezindleko zamandla zokumisa ukushisa okusethiwe.

I-LED UV ikhiqiza ukushisa okuncane kakhulu, idonsa ngemuva kwemojuli futhi ipholise uhlangothi lwe-substrate. Lokhu kwenza kube nokwenzeka ukuphrinta ngaphandle kokuguqulwa noma ukulimala ezinhlobonhlobo ezibanzi kakhulu zama-substrates azwela ukushisa kunokusebenzisa izibani ezikhipha i-mercury, okuhlanganisa amafilimu, amapulasitiki, nezinye izinto ezingabamumbi oyinki.

Enye yezinzuzo ezinkulu zezinhlelo zokuphulukisa i-UV ukususa isiteji sokumisa esidingekayo. Ukomisa impushana ukuze kugcinwe amashidi ukuthi anganamatheli emishinini yokunyathelisa ye-offset akusadingeki, ngenxa yokwelashwa kwe-UV, okunciphisa kakhulu ukuhlanzwa nokugcinwa kahle.

Wonke ama-ink alaphekayo nge-UV anenzuzo yokuhlala endaweni engaphansi esikhundleni sokungena kuwo, njengoba kwenza abanye oyinki abaningi, okunciphisa inani likayinki elidingekayo ukuze kukhiqizwe ukuminyana kwesithombe okuqhathanisekayo noyinki wendabuko. Lokhu kusiza kakhulu ezintweni ezingezona izimbotshana, lapho u-inki omncane uncanyelwa ukuphatha usayizi wamachashazi.

Indawo yesicelo sokuphrinta kwe-UV-LED ye-Offset nokuxubha ngesivinini esikhulu

Izici eziyinhloko ze-UV L enesivinini esikhulu ed p ukukhala s uhlelo ijubane nokusebenza kahle. Kuwuhlobo lwe UV LED yokuphrinta UV lokho kunciphisa inani lesikhathi esidingekayo ku-UV LED Printing System futhi kufakwe isibani esivamile semercury elashwe yi-UV.

Ngokusetshenziswa kwe-UV I-LED izophulukisa imithombo yokukhanya, ungakwazi ukuthola inki yebanga elide enamandla amakhulu ukuphulukiswa ngokushesha, ukucwebezela okuphezulu, ukwethembeka kombala, nokucaca kuyilapho futhi wonga amandla futhi uvikela imvelo. Ikhulula i-mercury ne-ozone, iqala khona manjalo, iphephile futhi ifaneleka, ingadingi ukushisa kwangaphambili, ivumela ukudiliza nokuhlanza phakathi kwama-splints, ne-UV. I-LED inesikhathi sokuphila esingafika ku-20,000+ amahora. ukupakisha ngokuphulukisa ngokushesha futhi cha  

Izinkinga zokomisa Iphrinta ye-inkjet

Imboni ye-inkjet ibone okusha kakhulu muva nje, futhi izinzuzo zokwelashwa kwe-UV-LED zingasetshenziswa ukwanelisa izimfuno zale mboni, yingakho imakethe njengamanje inika ubuchwepheshe bokuphulukisa be-UV-LED ukunakwa okukhulu. Izinzuzo ze-UV-LED inkjet UV L ed   p ukukhala s uhlelo   zihlanganisa ukonga amandla, ukusebenza kahle okukhulu, okuhle kakhulu Isixazululo se-UV LED , kanye nokuvumelana nezimo ezindaweni ezihlukahlukene. Izicelo zifaka ukuphrinta kwelebula nokupakishwa, ukuphrinta kwe-inkjet okukhulu, kanye ne-UV LED Printing System yokuhlobisa noma yezimboni.

Ukuphrinta okunamathelayo kwe-UV-LED konga amandla futhi kuhambisana nemvelo kunokuphrinta okujwayelekile kwe-UV, kunokuphila isikhathi eside, kunganciphisa ukusetshenziswa kwamandla kufika ku-70% kuya ku-80%, futhi kunokuvumelana nezimo okukhethekile ezintweni ezifana nephepha.

Lapho ukuthenga I-UV LED  kusuka?

Inkampani Zhuhai Tianhui Electronic Co., Ltd ., enye ephezulu UV L ed Abakhiqizi , isebenza ekuhlanzeni umoya kwe-UV Drove, i-UV Drove water sanitization, i-UV Drove UV LED yokuphrinta UV nokubuyisela, i-UV Drove diode, amamojula we-UV Drove nemikhiqizo ehlukene. Inesiphiwo se-Mastery neqembu lemisebenzi ukunikeza abathengi I-UV Drove Arrangements, futhi imikhiqizo yayo nayo izuze ukunconywa kwenani elikhulu lamakhasimende.

Ngokuqalisa okuphelele kokudala, ikhwalithi engaguquki nokwethembeka, kanye nezindleko ezifanele, Amagajethi e-Tianhui abesebenza emakethe yenqwaba ye-UV Drove. Ukusuka kumafrikhwensi amafushane ukuya kumade, izinto zimboza i-UVA, i-UVB, ne-UVC, enemininingwane egcwele ye-UV Drove esuka phansi iye emandleni aphezulu.

Sijwayelene nezinhlobonhlobo zezinhlelo zokusebenza ze-UV Led, okuhlanganisa ukukhulula i-UV, ukubuyisela kabusha kwe-UV, nokuhlanza i-UV.

Isiphetho

Inzuzo yamalambu e-UV asekelwe ku-LED ngaphezu kwamalambu asekelwe ku-arc akudala ukuthi akhanyisa lapho kunesidingo futhi alungele ukwelapha ngaso leso sikhathi, kanti amalambu endabuko asekelwe ku-arc kufanele ashiywe ekhanyiswe ngesikhathi sokukhiqiza futhi adinga isigaba sokuqala sokufudumala. , okubambezela ukukhiqizwa.
