Isibani se-UV LED njengomthombo wokukhanya ovamile, isimiso saso sokuphulukisa sibhekisela kumayinki e-UV ngemva kokushiswa kwemisebe ye-UV kuqalwa i-photoinitiator, ngaleyo ndlela ikhiqize ama-radicals mahhala noma ama-ion.Lawa ma-radicals amahhala noma ama-ion kanye nama-pre-polymers noma ama-monomers angenalutho ku-double bond cross-linking reaction, ukwakheka kwezakhi zofuzo ze-monomer, lezi zakhi zofuzo ze-monomer ziqala ukusabela ngeketanga ukukhiqiza okuqinile kwe-polymer kude ne-molecule.
Kunezici ezimbalwa ezibalulekile ezithonya ukwelapha kwe-UV LED:
Ukwelapha izici ezibonakalayo
Isivinini sokuphulukisa nokusebenza kweImishini yokwelapha ye-UV LEDkuncike kakhulu ebunzimeni bokukhanya ukuqala ama-molecule ezintweni zokuphulukisa.Ukwelashwa kwe-UV kunqunywa ukungqubuzana phakathi kwama-photon nama-molecule.Ukukhanya kubangela ukuthi ama-molecule ahlakazeke ngokufanayo ku-material.Ngaphezu kwezici zemishini yokwelapha, izici ze-optical kanye ne-thermodynamic zezinto zokuphulukisa kanye nokusebenzisana kwazo namandla akhazimulayo kunomthelela omkhulu enqubweni yokwelapha.
I-Spectral Absorption Rate
Inani lamandla okukhanya elimuncwa ama-UV njengoba anda ukujiya libizwa ngokuthi izinga lokumuncwa kwe-spectral.Lapho amandla engeziwe emunca eduze kwendawo, amandla amancane agcinwa ezingqimbeni ezijulile.Nokho, lesi simo siyahlukahluka kumaza ahlukene.Inani eliphelele lokumuncwa kwe-spectral lihlanganisa imiphumela yezibangeli zokukhanya, izinto ze-monomolecular, ama-oligomers, izithasiselo nama-pigments.
Ukucabangisisa nokuhlakaza
Kunokumuncwa, amandla okukhanya athintwa ukuguquka kwendlela kayinki, okuholela ekubonakaleni nasekuhlakazeni.Lokhu ngokuvamile kubangelwa izinto ze-matrix noma ama-pigments ezintweni ezelaphekayo.Lezi zici zinciphisa inani lamandla e-UV afinyelela izendlalelo ezijulile, kodwa zithuthukisa ukusebenza kahle kokwelapha endaweni yokusabela.
Izinga lokumuncwa kwe-infrared kanye nobude begagasi be-UV obufanelekile
Izinga lokushisa linomthelela obalulekile ejubaneni lokusabela kokwelapha, futhi ukukhuphuka kwezinga lokushisa ngesikhathi sokusabela nakho kudlala indima.Ama-ink e-UV ahlukene adinga ubude beza beza be-UV obuhlukile ukuze wenziwe ukwelashwa.Lapho ukhetha iyunithi yokwelapha, kubalulekile ukukhetha eyodwa ehambisana nobude beza obudingwa ama-UV.Ukusebenzisa aIyunithi yokwelapha ye-UV LEDngobude obufanele buzonikeza imiphumela engcono yokwelapha.
