Ukuphulukiswa kwe-UV LED kwe-UV varnish inqubo ye-photopolymerization esebenzisa ama-diode akhipha ukukhanya (ama-LED) ukomisa ngokushesha nokuqinisa ama-varnish ewuketshezi. Ngokungafani nezindlela zendabuko zokomisa ezithembele ekushiseni noma ekuhwamukeni, izinhlelo ze-UV LED zikhipha ama-wavelengths athile wokukhanya kwe-ultraviolet - imvamisa i-365nm, i-385nm, noma i-395nm - ebangela ama-photoinitiators ngaphakathi kwe-varnish. Lokhu kusabela kubangela ukuthi ama-oligomers awuketshezi nama-monomers axhumanise cishe ngokushesha, akha ifilimu eqinile eqinile, ecwebezelayo noma ye-matte. Lobu buchwepheshe bamukelwa kabanzi ekunyatheliseni nasekupakisheni ngoba bukhiqiza ukushisa okuncane kakhulu, budla amandla amancane, futhi buqeda ukukhishwa kwamakhemikhali e-organic volatile (VOCs), okwenza kube kuphephe kuma-substrates azwela ukushisa njengamafilimu amancane namapulasitiki. Yini i-UV LED Curing Technology? Ukuphulukiswa kwe-UV LED kuyindinganiso yesimanje yokuqinisa ukumbozwa kwezimboni nama-inks. Enhliziyweni yayo, ithatha indawo yama-bulbs abanzi wesikhathi esidlule ngemithombo yokukhanya ye-elekthronikhi egxile, enamandla kakhulu. Kuma-varnishes ngokuqondile, inqubo incike kwinqubo yamakhemikhali "yokukhiya nokhiye". I-varnish yakhiwe ngama-photoinitiators athile aklanyelwe ukumunca ibhande elincane eliqondile lokukhanya kwe-UV elikhishwa yisibani se-LED. Lapho ukukhanya kushaya i-varnish emanzi, kubangela ukusabela kochungechunge okuqinisa ukumbozwa ngama-milliseconds. Ngoba ama-LED avula futhi avale ngokushesha ngaphandle kwesikhathi sokushisa, le ndlela isebenza kahle kakhulu emigqeni yokukhiqiza edinga amandla okuma nokuhamba. Indima yama-wavelengths Akuwona wonke ukukhanya kwe-UV okufanayo. Ukwelashwa kwe-UV LED kuvame ukusebenza ebangeni le-UVA. Ubude obuvame kakhulu be-varnishes ngu-395nm ngoba inikeza ukujula okuhle kakhulu kokwelashwa, ukungena ngezingqimba ezijiyile ...
