Nrog rau kev nce ntxiv ntawm kev siv tshuab UV curing hauv kev lag luam luam ntawv, txoj kev luam ntawv siv UV-LED ua lub teeb ci tau nyiam ntau dua thiab ntau dua ntawm cov tuam txhab luam ntawv. UV-LED yog ib hom LED, uas yog lub teeb pom kev ib qho wavelength. Nws tuaj yeem muab faib ua plaub pawg: UVA ntev nthwv dej, UVB nruab nrab nthwv dej, UVC luv nthwv dej thiab UVD nqus tsev. Qhov ntev ntawm qhov wavelength, qhov muaj zog nkag mus, feem ntau qis dua 400nm. UV-LED wavelengths siv hauv kev lag luam luam ntawv feem ntau yog 365nm thiab 395nm.

Cov kev cai rau cov ntaub ntawv luam ntawv

Kev luam ntawv UV-LED tuaj yeem siv rau cov khoom tsis nqus dej, xws li PE, PVC, thiab lwm yam; cov khoom siv hlau, xws li tinplate; ntawv, xws li ntawv coated, kub thiab nyiaj cardboard, thiab lwm yam. Kev luam ntawv UV-LED nthuav dav ntau yam ntawm cov substrate, ua rau kev luam ntawv offset los luam cov khoom xws li lub xov tooj ntawm tes rov qab npog.
