Ukwelashwa kwe-UV LED kushesha kangakanani? Ukuvula ijubane elisheshayo lezimboni
How Fast is UV LED Curing?
Ukwelashwa kwe-UV LED kushesha kangakanani? Isikhathi sokuphulukisa ama-inks, ukumboza, nokunamathisela kungathatha ama-milliseconds kuya kumasekhondi ambalwa ngenqubo esheshayo, ephumelelayo yokuphulukisa i-UV LED. Ngokungafani nezibani zendabuko ze-mercury ezisebenzisa ubuchwepheshe be-UV, UV LED izinhlelo zinikeza ukukhanya okugcwele kwe-UV (imvamisa i-365-405 nm), futhi ama-photoinitiators ekwakhiweni aqala ukusebenza ngokushesha.
Ezinye zezici zesikhathi sokwelashwa yilezi:
• Uma kusetshenziswa ukukhanya okwengeziwe, isikhathi esithathiwe siyancipha, futhi isivinini sokuphulukisa sincike kakhulu ekuqineni. Isibonelo, okukhipha kwe-UV LED kwe-8-16 W / cm² kungaphulukisa ngakho-ke ama-inks amaningi angaphulukisa ngaphansi kwe-1 yesibili.
• Izinto ezingaphezulu ze-opaque noma ezijiyile ziletha isidingo samandla amaningi ukuze i-polymerize ngokuphelele. Thatha isibonelo se-600-800 mJ / cm².
• Izici ezibonakalayo ezifana nokushuba nohlobo lwe-photoinitiator ye-inki, kanye nokunamathela nokumboza, kunqunywa ijubane lokwelashwa.
• Ekulungiseleleni kohlelo olufanele, isivinini sokuhambisa singasethwa ku-50-150m ngomzuzu ngezinhlelo ze-LED.
Ukuphulukiswa kwe-UV LED kusheshise izinhlelo zokukhiqizwa kwamadivayisi wezokwelapha, i-elekthronikhi, nokuphrinta ngenxa yokushisa okuncishisiwe nokuthuthukiswa kwejubane nokuqina. Isilinganiso esisheshayo sokuphrinta i-UV LED esinganikeza uma kuqhathaniswa nezindlela ezijwayelekile sifinyelela ezikhathini eziyi-10.
Ukuqonda ijubane lokuphulukisa i-UV LED
Ukuphulukiswa kwe-UV LED kungumsebenzi we-photochemical osebenzisa ukukhanya kwe-ultraviolet ukudala ukusabela ku-photo-initiator okuholela ekuxhumaniseni i-polymerization yama-inks, ama-adhesives, noma ukumboza. Ngokungafani nezindlela zangaphambilini zokwelapha, ngokuphulukiswa kwe-UV LED, ukwelashwa okugcwele kutholakala ngama-millisecond kuya kumasekhondi, kuye ngokuthi amapharamitha ahlukene.
Speed Influencing Factors on Curing
1. Uhlobo lwe-Photoinitiator
Ama-photoinitiators ahlukene asabela ekuqineni okuthile. Kubalulekile ukukhetha i-photoinitiator efanele ukuze uzuze ukwelashwa okuphumelelayo.
2. Ukushuba kwezinto ezibonakalayo
Ukuba nezinto ezijiyile kudinga ukuchitha amandla amaningi ukuze uziphilise ngokuphelele. Ukushintsha ukuqina kwamandla kusiza ukufinyelela ezingeni elifanele lokujiya.
3. Substrate Material
Ukungena kwe-UV kuthinteka ukucaca kwe-substrate kanye nezakhiwo zokumuncwa. Ukumunca izinto kuzodinga izinguquko ku-irradiance noma isikhathi sokuvezwa.
4. Amandla UV LED isibani
Izibani ezinamandla kakhulu zingaletha amandla amaningi, zinciphise isikhathi sokuphulukisa; izibani nazo kufanele zilinganiselwe ukugwema ukulimaza i-substrate.
5. Idizayini yesistimu
Ukuphulukisa ukufana nokusebenza kahle kuthinteka ngama-reflectors, izindlela zokupholisa, nokuhlelwa kwesibani.
6. Izinga lokushisa kwemvelo
Izinga lokushisa langaphandle lithinta i-viscosity yezinto ezibonakalayo kanye nokusebenza kahle kwenqubo. Izinga lokushisa elingaguquguquki linikeza umphumela omuhle.
7. Ibanga phakathi kwesibani ne-substrate
Ukusondela kwandisa ukukhanya, kepha lokhu kwandisa amathuba okushisa ngokweqile. Ukushintsha ibanga ngaphakathi kwemingcele kungasiza ukulinganisela ijubane lokuphulukisa ngenkathi kuqinisekiswa ukuthi izinto aziphazami.
8. Isivinini sokuhambisa
Ezinhlelweni ezizenzakalelayo, ijubane lokuhambisa lishintsha isikhathi esitholakalayo sokuvezwa. Ukuze uqinisekise ukusebenza kahle ekwelapheni, isivinini esisheshayo sidinga ukukhanya okuphezulu.
Ukulinganisa nokuhlola isivinini sokuphulukisa
1. UV Radiometers
Amadivaysi we-UV afana ne-ILT800 Cure Right Radiometer alinganisa ukukhanya nokuminyana kwamandla ukuqinisekisa ukuthi ukuphulukiswa okufanele kwezinto kuhanjiswa ngokungaguquguquki.
2. Abahlanganisi be-UV
La mathuluzi asiza ukuqinisekisa nokwenza ngcono izinqubo ngokulinganisa inani eliphelele lamandla e-UV alethwa ngokuhamba kwesikhathi.
3. Izindlela Zokuhlola Ukwelapha
Izinga lokwelashwa, kanye nokunamathela komhlaba, kulinganiswa kusetshenziswa ukuhlolwa kokuhlikihla okuphindwe kabili kwe-MEK noma ukuhlolwa kokumelana ne-mar kanye ne-FTIR spectroscopy.
Izicelo kanye nezinzuzo ze-UV LED Curing esheshayo
1. Imboni yokunyathelisa
Inika amandla ukuphrinta okusheshayo ngokumiswa okusheshayo, kuthuthukisa amazinga okukhiqiza nokunciphisa isikhathi sokuphumula.
2. Enamathela kanye nama-adhesives
Kuzuzisa izimboni zezimoto ne-elekthronikhi ngokuthuthukisa ukusebenza kokukhiqizwa okusheshayo kokuphulukisa.
3. Amadivaysi Wezokwelapha
Ukuphulukisa ngokushisa okuphansi kubalulekile ezingxenyeni zezokwelapha ezizwela ukushisa ngobuqotho bomkhiqizo.
4. Ukusebenza kahle kwamandla
Ngokungafani nezibani zendabuko ze-mercury, izinhlelo ze-UV LED zisebenzisa amandla amancane, zihlinzeka ukonga futhi zibe nobungani bemvelo.
Umehluko phakathi kokwelapha kwe-UV LED nezindlela zendabuko
Kuyo yonke le minyaka, izinhlelo zendabuko zokuphulukisa izibani ze-mercury ziye zahlala zithandwa, kepha ukusetshenziswa kwazo kwamandla aphezulu, isikhathi eside sokushisa, kanye nokukhathazeka kwemvelo kwe-mercury kuyaqhubeka nokuphakamisa ukukhathazeka.
Ngokuphambene nalokho, ukwelashwa kwe-UV LED kunezinzuzo ezilandelayo:
• Ukuqala okusheshayo: Asikho isikhathi sokushisa
• Ukusebenza Kwezindleko Okuthuthukisiwe: Uma kugcinwa kahle, ama-LED e-UV angahlala amahora ayizinkulungwane ezingamashumi amabili, okunciphisa izindleko zesondlo.
• Ukusebenza kahle kwamandla amaningi: Uma kuqhathaniswa nezinhlelo zendabuko, kunamazinga aphezulu okusebenza kahle (kuze kufike kumaphesenti angamashumi ayisishiyagalombili) ekusetshenzisweni kwamandla.
• Izingxenye ze-Eco-Friendly: Azikho izinto eziyingozi, njenge-mercury eyingozi.
Ukulungiswa kwejubane lokuphulukisa le-UV LED
Ukukhetha ama-photoinitiators afanele: Qinisekisa ukuthi ama-photoinitiators ahlinzekiwe ane-wavelengths ahambisanayo ne-UV LED.
Lungisa i-Irradiance nesikhathi sokuvezwa: Shaya ibhalansi ukuze uqinisekise ukuthi akukho ukwelashwa ngokweqile noma ukwelashwa okungaphansi.
Gcina izimo zemvelo: Qinisekisa ukuthi amazinga okushisa nomswakama agcinwa.
Bamba iqhaza ekulondolozeni okuvimbelayo: Qinisekisa ukuhlanza njalo nokulinganisa kwangaphambili kohlelo lwe-UV LED.
Ukuqinisekiswa kwe-Methodical: Sebenzisa abahlanganisi bokuqinisekiswa kwenqubo.
Izinzuzo
• Amazinga okukhiqiza athuthukisiwe: Ukwanda kokukhiqizwa ngoba izingxenye eziningi noma imikhiqizo ingacutshungulwa ngesikhathi esifushane.
• Ukunciphisa i-Factory Footprint: Ngaphandle kwesidingo semigudu emide yokomisa, isikhala esengeziwe sefektri siyatholakala.
• Ukusetshenziswa kwamandla aphansi: Uma kuqhathaniswa nezibani zendabuko ze-mercury, ama-UV LED asebenza kahle kakhulu ngokombono wokusetshenziswa kwamandla. Bachitha ugesi omncane kakhulu, okuholela ekulinganisweni kokusebenza kahle okukhulu (i-UV LED).
• Ukucubungula okusheshayo: Izinto eziphulukisiwe zivame ukubekwa noma ukucutshungulwa ngokushesha ngemuva kokuphulukisa, okusiza ekwenzeni lula ukuhamba komsebenzi.
• Ubungani bemvelo: Uma kuqhathaniswa nezindlela ezivamile, izinhlelo ze-UV LED azinawo ama-solvents, i-ozone, noma i-mercury, okwandisa kakhulu ubungane babo bemvelo.
• Ukuphulukisa ama-substrates azwela ukushisa: Ngokungafani nezibani zendabuko, ama-LED e-UV akhipha ukushisa okuphansi, okuvumela ukusetshenziswa kwamapulasitiki amancane abucayi noma amafilimu kanye nezingxenye ezithile ze-elekthronikhi ezithambekele ekusontekeni noma ekuwohlokeni.
Isiphetho
Yonke imboni ithola izinzuzo eziguqukayo ngenxa yobuchwepheshe bokwelapha i-UV LED. Inokwethenjelwa ngempumelelo, iyashesha ngokujulile, futhi inikeza imiphumela engenakuqhathaniswa. Ayinakuqhathaniswa ngesivinini nomnotho wamandla, kusuka ezikhathini zokuphulukisa ezingaphansi komzuzwana kuya ezindleleni zendabuko zokuphulukisa. Kubuye kuncike kumapharamitha we-irradiance, umthamo wamandla, izakhiwo zezinto ezibonakalayo, kanye nokwakhiwa kohlelo, kepha ngokucushwa okufanele, kungenzeka ukwandisa kakhulu amazinga okukhiqiza ngenkathi kugcinwa izinga lokunemba. Ukuze uthole ulwazi oluthe xaxa mayelana nobuchwepheshe bokwelapha i-UV LED, sivakashele ku- UVET Technology.
