Iyini i-UV LED Spot Curing System?

Ekukhiqizeni ngokunemba, ikhono lokuletha ukukhanya okuphezulu endaweni egxilile kubalulekile ekuhlanganisweni kwasendaweni nasekuhlanganeni. Ngenkathi izinhlelo ezinkulu zokuphulukisa ziphatha yonke indawo, uhlelo lokuphulukisa indawo ye-UV LED lunikeza ukunemba kokuhlinzwa okudingekayo kwezingxenye eziyinkimbinkimbi.

Lo mhlahlandlela uchaza lezi zinhlelo, uhlola imishini yazo yokusebenza, futhi unikeza isiqondiso esisebenzayo ekukhetheni ubude be-wavelength nokuphepha. Ngokuqonda imingcele yezobuchwepheshe yokuphulukisa indawo, onjiniyela benqubo bangafinyelela izikhathi zomjikelezo ezisheshayo namandla aphakeme okubopha ngisho nasezinhlelweni ezinzima kakhulu zezandla noma ezizenzakalelayo.

Kuyini uhlelo lokuphulukisa indawo ye-UV LED?

Uhlelo lokuphulukisa indawo ye-UV LED uhlelo lokukhanya lwe-ultraviolet olugxile olwenzelwe ukuletha amandla e-UV alawulwayo ezindaweni ezithile ezincane zokuphulukisa izinamathiselo, ukumboza, nezinye izinto. Uzothola ukuthi lezi zinhlelo ngokuvamile ziqukethe iyunithi yokulawula kanye nekhanda elilodwa noma ngaphezulu le-LED noma imihlahlandlela yokukhanya egxile ugongolo endaweni ehlosiwe.

Ngokungafani nezinhlelo zezikhukhula, uhlelo lokuphulukisa indawo lunikeza "ichashazi" eliphakeme lokukhanya, imvamisa lincane njenge-3 mm ububanzi. Lokhu kukuvumela ukuthi ukhombe umugqa owodwa wesibopho ebhodini lesifunda noma kudivayisi yezokwelapha ngaphandle kokuveza izingxenye ezizungezile ezizwela ukushisa emisebeni. Lezi zinhlelo zijwayelekile ku-micro-electronics, umhlangano we-optics, kanye nokukhiqizwa kwezokwelapha ngokunemba.

Isebenza kanjani i-UV LED Spot Curing System?

Uhlelo lokuphulukisa indawo ye-UV LED lusebenza ngokukhiqiza ukukhanya kwe-ultraviolet kuma-wavelengths athile avumela ama-photoinitiators kuma-adhesives nasekugqokeni ukuqala i-polymerization. Lapho i-LED inikwa amandla, ikhipha ibhande elincane lokukhanya kwe-UV elidlula kuma-optics akhethekile noma imihlahlandlela yokukhanya uketshezi ukugxila kuma-photon endaweni ephezulu.

Lapho la ma-photon eshaya ukunamathela okuwuketshezi, avusa ama-photoinitiators, okwenza ukuxhumanisa okusheshayo kwamakhemikhali okuguqula uketshezi lube yi-polymer eqinile kungakapheli imizuzwana. Ngoba ama-LED akhipha ukushisa okuncane kakhulu kwe-infrared, inqubo ihlala ipholile, ivimbela ukusonteka noma ukuwohloka kwama-substrates epulasitiki noma amasekethe we-elekthronikhi abucayi.

Kufanele usebenzise nini uhlelo lokuphulukisa indawo esikhundleni sezinye izinketho?

Uhlelo lokuphulukisa indawo kufanele lusetshenziswe lapho kudingeka ukuphulukiswa okuqondile, okunendawo encane futhi izinhlelo ezinkulu zezikhukhula noma zokuhambisa azidingekile noma zingasebenzi. Uzothola la mathuluzi abalulekile emisebenzini yomhlangano wesandla lapho opharetha kufanele abambe izingxenye endaweni ngenkathi isibopho sibetha.

Zilungele futhi "ukubamba" izingxenye ngaphambi kokuthuthela esigabeni sesibili sokuphulukisa noma ukwenza ukulungiswa okuncane emihlanganweni yenani eliphezulu. Uma ingxenye yakho inkulu kodwa indawo yangempela yesibopho incane, uhlelo lwendawo lunamandla kakhulu futhi lubiza kakhulu kunesibani sezikhukhula sendawo ebanzi, njengoba sigxila wonke amandla atholakalayo kuphela endaweni yesibopho esisebenzayo.

How do Wavelength and Adhesive Chemistry Influence Spot Curing?

Ukukhishwa kwe-wavelength yohlelo lokuphulukisa indawo ye-UV LED kufanele kufane nephrofayili yokumuncwa kwe-photoinitiator yokunamathela ukuze kwelapheke okuphumelelayo. Kufanele uhlale uqinisekise ukuthi ngabe i-resin yakho isabela kangcono ku-365 nm, 385 nm, noma i-395 nm, njengoba ama-LED akhipha ukukhanya ebangeni elincane kakhulu le-spectral uma kuqhathaniswa nezibani ze-mercury.

Uma uzama ukwelapha ukunamathela kwe-365nm ngesibani esingu-395 nm, ama-photoinitiators kungenzeka angasebenzi, okuholela ekwelapheni okungaphelele noma isibopho esingenalo ubuqotho besakhiwo. Ukuqhathanisa okulungile kwe-wavelength kuqinisekisa ukuthi amandla e-ultraviolet amuncwa ngokuphelele, okuholela ekwelapheni okujulile, okuphelele kulo lonke ubukhulu bezinto ngaphandle kokushiya i-resin ewuketshezi ku-interface.

Yiziphi izici ezithinta isikhathi sokwelapha ngohlelo lokuphulukisa indawo?

Isikhathi sokuphulukisa ngohlelo lokuphulukisa indawo ye-UV LED kuncike ekwakhiweni kokunamathisela, ukuqina kokukhanya, ubude be-wavelength, nebanga ukusuka ebusweni. Uzobona ukuthi njengoba ibanga phakathi kwesibani sendawo nokunamathela likhuphuka, ukuqina kwehla kakhulu, okudinga isikhathi eside sokuchayeka ukufinyelela umthamo odingekayo.

Izingqimba ezijiyile zokunamathela noma lezo eziqukethe ama-pigment amnyama nazo zidinga isikhathi esithe xaxa sokuthi ama-photon angene esisekelweni sesibopho. Ukuze uthuthukise i-throughput, kufanele ulinganise uhlelo lwakho ukuletha ukuqina okuphezulu kakhulu ebangeni eliseduze eliphephile lokusebenza ngenkathi usebenzisa i-wavelength ehambisana ngokuphelele ne-chemistry yakho ethile.
