Kodi chifukwa chachikulu chogwiritsira ntchito zomatira zochiritsira za LED ndi chiyani pa zomatira zochiritsira za UV?
Zomatira zochiritsira za LED zimachiza mu masekondi 30-45 pansi pa gwero la kuwala kwa 405 nanometer (nm) wavelength.Zomatira zachikhalidwe zochizira kuwala, mosiyana, zimachiritsa pansi pa kuwala kwa ultraviolet (UV) ndi mafunde apakati pa 320 ndi 380 nm.Kwa akatswiri opanga mapangidwe, kutha kuchiritsa zomatira pansi pa kuwala kowoneka bwino kumatsegula njira zingapo zomangira, zotsekera ndi kusindikiza zomwe poyamba sizinali zoyenera kupangira mankhwala ochizira, chifukwa m'mapulogalamu ambiri, magawowo samatha kufalikira mu UV wavelength koma amalola kuti ziwonekere. kufala kwa kuwala.
Kodi ndi zinthu ziti zomwe zingakhudze nthawi ya machiritso?
Nthawi zambiri, kuwala kwa nyali ya LED kuyenera kukhala pakati pa 1 ndi 4 watts/cm2.Kuganiziranso kwina ndi mtunda wochokera ku nyali kupita kumalo omatira, mwachitsanzo, kutali ndi nyali kuchokera ku zomatira, nthawi yayitali yochiritsa.Zina zomwe ziyenera kuganiziridwa ndi makulidwe a zomatira, chocheperako chimachiritsa mwachangu kuposa chowonjezera, komanso momwe magawowo amawonekera.Njirazo ziyenera kusinthidwa kuti ziwonjezeke nthawi zochizira, kutengera osati ma geometries a kapangidwe kake, komanso mtundu wa zida zomwe zimagwiritsidwa ntchito.
Kodi mumawonetsetsa bwanji kuti zomatira za LED zachira kwathunthu?
Chomatira cha LED chikachiritsidwa bwino, chimapanga malo olimba komanso osasunthika omwe amakhala osalala agalasi.Nkhani yoyesa kuchiritsa pamafunde ataliatali ndi vuto lotchedwa oxygen inhibition.Kutsekereza kwa okosijeni kumachitika pamene mpweya wa mumlengalenga uletsa njira ya free-radical polymerization yomwe imachiritsa pafupifupi zomatira zonse za UV.Zimapangitsa kuti pakhale malo ovuta, ochiritsidwa pang'ono.
