Namuhla, ukushintshwa kokuphulukiswa kwe-UV LED kumelela ukugxuma okukhulu phambili. Akuyona nje isibani esikhanyayo esihlukile; Ushintsho oluyisisekelo endleleni esiphatha ngayo ijubane lokukhiqiza, ukuhambisana kwe-substrate, kanye nomthwalo wemvelo. Uma ungumguquli ofuna ukwandisa umshini wakho noma umnikazi womkhiqizo ofuna amalebula asezingeni eliphakeme, ukuqonda lobu buchwepheshe akusekho ukuzikhethela—kubalulekile. Yini ngempela ukuphulukiswa kwe-UV ye-LED ekunyatheliseni kwe-flexo? Ukuphulukiswa kwe-UV ye-LED ephrintiweni ye-flexo kuyindlela "yokuphulukisa okubandayo" esebenzisa ukukhanya okuncane kwe-ultraviolet ukwenza ama-inks e-polymerize ngokushesha. Ngokungafani nezibani ze-mercury ezibanzi, izinhlelo ze-LED zikhipha ama-wavelengths athile (imvamisa i-385nm noma i-395nm) ukuvusa ama-photoinitiators, ukuguqula inkinobho ewuketshezi ibe yifilimu eqinile, ehlala isikhathi eside ngama-milliseconds. Isayensi Ngemuva Kwekhambi Ngokuyinhloko, ukuphrinta kwe-flexographic kumayelana nokudlulisa inki uketshezi ezintweni ezibonakalayo. Inselelo ibilokhu ithola leyo yinki ukuthi ihlale ibekwe ngaphandle kokugcoba, ukusabalalisa, noma ukungena ngokujulile kakhulu ku-substrate. Ekusethweni okujwayelekile kwe-UV ye-LED, iyunithi yokuphrinta ifakwe uhla oluhlangene lwama-diode aphezulu. Lapho i-substrate idlula ngaphansi kwalolu hlu, ama-LED aqhumisa inkinobho emanzi ngokukhanya okuphezulu kwe-irradiance. Lokhu kukhanya akumisi inki ...
