Uhlelo oluhle kakhulu lokuphulukisa lwe-UV LED lokuphrinta ilebula le-Flexo

Uhlelo oluhle kakhulu lokuphulukisa lwe-UV LED lokuphrinta ilebula le-flexo yilolo oluhlanganisa ukukhanya okuphezulu kwe-peak (imvamisa i-12-20 W / cm²) nokuphathwa okusebenzayo kokushisa ukusingatha ama-substrates azwela ukushisa ngaphandle kokuhlanekezela. Ngokungafani nezibani zendabuko ze-mercury, uhlelo oluhle lwe-LED lunikeza amandla okuvula / ukuvala okusheshayo, ukukhishwa okufanayo kwe-UV kulo lonke ububanzi bewebhu, kanye nesikhathi sokuphila esingaphezu kwamahora angama-20,000. Kwabaguqula ilebula, ukukhetha "okuhle kakhulu" uhlelo oluvumela ukubuyiselwa kabusha kwe-modular, ukuqinisekisa ukuhambisana nokucindezela okukhona ngenkathi kunciphisa ukusetshenziswa kwamandla kuze kufike ku-70%.

Yini echaza uhlelo oluhle kakhulu lwe-UV LED lwe-flexo?

Ukukhetha ubuchwepheshe obufanele bokwelapha kubalulekile kwikhwalithi yelebula. Yize kunezinketho eziningi emakethe, izinhlelo ezisezingeni eliphakeme zabelana ngezici ezithile ezithinta ngqo umugqa wakho ophansi nekhwalithi yokuphrinta.

High Peak Irradiance and Dose

Ukuphrinta kwe-flexographic, ikakhulukazi uma ugijima ngesivinini esikhulu, udinga uhlelo oluletha ukuminyana kwamandla okungaguquguquki. Izinhlelo ezinhle kakhulu zinikeza ukukhanya okuphezulu ukuqinisekisa ukuthi inkinobho ingena futhi iphulukisa yonke indlela eya ku-substrate - ebalulekile ekufezeni ukunamathela okuhle ezintweni ezingezona i-porous njengamafilimu nama-foils.

Thermal Management Efficiency

Esinye sezizathu eziyinhloko zokuthi kungani abaguquli bashintshela ku-UV LED ukuphulukiswa kwe-flexo namalebula yikhono lokuphrinta ezintweni ezizwela ukushisa. Uhlelo oluphakeme lusebenzisa amanzi athuthukile noma ukupholisa umoya ukugcina i-LED array emazingeni okushisa okuzinzile okusebenza. Lokhu kuzinza kuvimbela "ukwehla okushisayo" okungaholela ku-inki engalapheki phakathi nokukhiqizwa okude.

Kungani ama-converters eshintsha kusuka ku-Mercury kuya ku-LED?

Ukushintshwa kusuka kumalambu ajwayelekile e-mercury arc kuya ku-LED kuqhutshwa ukusebenza kahle nokuguquguquka kwe-substrate.

Energy Efficiency and Cost Savings

Izibani zendabuko ze-mercury zishisa futhi zichitha amandla amakhulu akhiqiza ukushisa kwe-infrared. Ngokuphambene nalokho, izinhlelo ze-UV LED zidla amandla amancane kakhulu ngoba zikhipha kuphela ubude obuthile obudingekayo ekwelapheni (imvamisa i-395nm noma i-385nm). Baphinde bacime ngokushesha phakathi kwemisebenzi, baqede imijikelezo yokushisa nokupholisa echitha ugesi.

Expanded Substrate Capabilities

Ngoba izinhlelo ze-LED zikhipha ukushisa okungenangqondo ku-substrate, abaguquli bangakhulisa iminikelo yabo yomkhiqizo. Ungasebenzisa ngokuzethemba amafilimu amancane angasekelwa, imikhono yokunciphisa, namalebula okushisa ngaphandle kokukhathazeka ngokusotha kwewebhu noma ukuhlanekezela.

Ukuze uthole ukujula kokungafani kwezobuchwepheshe, kuyasiza ukuqonda ngokunembile kuyini ukwelashwa kwe-LED UV ekunyatheliseni kwe-flexo uma kuqhathaniswa nezindlela ezindala.

Ingabe ukuphulukiswa kwe-UV LED kusebenza kuzo zonke izinhlelo zokusebenza zelebula?

Yebo, kepha kudinga ukwakheka kwe-inki okuhambisanayo.

Ngenkathi i-hardware ye-UV LED iqinile, i-chemistry ibaluleke ngokulinganayo. Uhlelo "oluhle kakhulu" luhle kuphela njengoyinki oluphulukisayo. Iningi labakhiqizi abakhulu be-inki manje banikela ngama-inki aphindwe kabili noma aqondene ne-LED aklanyelwe ukusabela kubude obuncane be-395nm.

Kodwa-ke, kumalebula okupakisha ukudla, kufanele uqinisekise ukuthi uhlelo lwakho lunikeza "ukwelashwa okuphelele" ukuvimbela ukufuduka. Izinhlelo ze-LED zokusebenza eziphezulu zihle kakhulu kulokhu ngoba okukhiphayo kwazo akuwothi phansi ngokuhamba kwesikhathi njengama-mercury bulbs, ukuqinisekisa ukuthi ikhwalithi yokwelapha ngosuku lwe-500 iyafana nosuku lwe-1.

How do UV LED Systems Improve Press Uptime?

Baqeda ukushintshwa kwe-bulb kanye nesikhathi sokuphumula kwesondlo.

I-bulb ejwayelekile ye-mercury ingahlala amahora ayi-1,000 kuye kwangama-2,000 ngaphambi kokuthi ukukhishwa kwayo kwehle kakhulu. Uhlelo lwe-UV LED luvame ukuhlala amahora angaphezu kwama-20,000. Lokhu kusho ukuthi awuyeki ukushicilela njalo emavikini ambalwa ukushintsha ama-bulbs ayingozi, agcwele i-mercury. Ukungaguquguquki kwe-LED kusho ukuthi opharetha bachitha isikhathi esincane ukuxazulula izinkinga zokwelapha kanye nesikhathi esiningi sokuphrinta amalebula athengiswayo.

Ukuqhathanisa: I-Mercury Arc vs. UV LED yamalebula

Imibuzo Evame Ukubuzwa

Iyini i-ROI ohlelweni lokuphulukisa lwe-UV LED?

Ngenkathi ukutshalwa kwezimali kokuqala kuphakeme kunezinhlelo ze-mercury, i-ROI ivame ukutholakala ezinyangeni eziyi-12 kuye kwezingu-24 ngokulondolozwa kwamandla, ukuqedwa kwezindleko zokushintshwa kwe-bulb, kanye nokwanda kwesikhathi sokucindezela.

Ngingakwazi ukubuyisela kabusha umshini wami okhona we-flexo nge-UV LED?

Yebo. Izinhlelo eziningi zanamuhla ze-UV LED zenzelwe izici zefomu le-modular ngokukhethekile ukubuyisela kabusha. Imvamisa zingangena esikhaleni esifanayo namakhasethi akho akhona.

Ingabe ukuphulukiswa kwe-UV LED kuphephile kumalebula okudla?

Yebo, inqobo nje uma usebenzisa ama-inki we-LED aphansi futhi uqinisekise ukuthi uhlelo lulinganisiwe ukuletha umthamo ofanele. Ukungaguquguquki kwe-LED empeleni kwenza kube kuphephe ekulawuleni inqubo kunama-bulbs e-mercury ahlazisayo.

Ingabe ngidinga ukushintsha imiqulu yami ye-anilox ye-UV LED?

Ngokuvamile, cha. Ngokuvamile, ungasebenzisa i-anilox yakho ekhona. Kodwa-ke, ngoba ama-inks e-LED angaba nama-viscosities ahlukene noma imithwalo ye-pigment, ukulungiswa okuncane kwevolumu yeseli kungalungiswa kamuva ukuthola imiphumela emihle.

Yimaphi ama-wavelength angcono kakhulu ukuphrinta ilebula le-flexo?

Indinganiso yomkhakha yokuphulukiswa kwelebula le-flexo ingu-395nm. Le wavelength inikeza ibhalansi engcono kakhulu yokujula kwephuluki (ukungena) kanye nokwelashwa komhlaba wokushuba kwezingqimba ze-inki ezivame ukusetshenziswa ekunyatheliseni ilebula.

Key Takeaways

• Ukuphathwa kokushisa: Izinhlelo ezinhle kakhulu zikuvumela ukuthi uphrinta kumafilimu amancane, azwela ukushisa ngaphandle kokuhlanekezela.
• Ukungaguquguquki: I-LED inikeza ukukhishwa okufanayo kwamahora angama-20,000 +, kuqeda ukuhlukahluka kwama-mercury bulbs.
• Ukonga Amandla: Lindela ukunciphisa izindleko zamandla okwelapha kuze kufike ku-70% ngenxa yamakhono okuvula / ukuvala okusheshayo.
• Ukuhambisana kwe-Ink: Qinisekisa ukuthi ubhangqa i-hardware yakho ngama-inki alungiselelwe i-LED noma ama-double-cure ngemiphumela ephumelelayo.

Isiphetho

Ukuthola uhlelo oluhle kakhulu lokuphulukisa lwe-UV LED lwamalebula we-flexo kumayelana nokulinganisa amandla, ukuthembeka, nokuhlanganiswa. Ngokushintshela kwisisombululo sekhwalithi ephezulu se-LED, uqinisekisa ikamelo lakho lokucindezela, wehlise indawo yakho yemvelo, futhi uvule umnyango wezinhlelo zokusebenza ezintsha ezinenzuzo njengemikhono yokuncipha.

Uma usukulungele ukuthuthukisa amakhono akho okuphrinta ilebula, xhumana nathi namuhla ukuze uxoxe ngokucushwa okuhle kwe-UV LED komshini wakho othile.
