Ni iyihe mpamvu nyamukuru yo gukoresha kole za LED zivura kurusha kole za UV zivura?
Kole zo gushushanya za LED zisanzwe zikira mu masegonda 30-45 munsi y'urumuri rwa nanometero 405 (nm). Kole zo gushushanya zisanzwe zikira mu buryo bw'urumuri, mu buryo bunyuranye, zikira mu buryo bw'urumuri rwa ultraviolet (UV) rufite uburebure bwa 320 na 380 nm. Ku bahanga mu by'ubwubatsi, ubushobozi bwo gushushanya kole zose munsi y'urumuri rugaragara bufungura uburyo butandukanye bwo gufatanya, gufunga no gufunga mbere bitari bikwiriye ibikoresho byo gushushanya mu buryo bw'urumuri, kuko mu bikorwa byinshi substrates zishobora kudakwirakwira mu buryo bw'uburebure bwa UV ariko zigatuma urumuri rugaragara rwoherezwa.
Ni ibihe bintu bimwe na bimwe bishobora kugira ingaruka ku gihe cyo gukira?
Ubusanzwe, ubukana bw'urumuri rw'itara rya LED bugomba kuba hagati ya wati 1 na 4/cm2. Ikindi kintu cyo kwitaho ni intera iri hagati y'itara n'urwego rw'ubukorikori, urugero, uko itara rigenda kure y'urukorikori, ni ko igihe cyo kurutunganya kiba kirekire. Ibindi bintu bigomba kuzirikanwa ni ubunini bw'urwego rw'ubukorikori, urwego rworoshye rurakira vuba kurusha urwego runini, n'uburyo substrates zibonerana. Inzira zigomba kuvugururwa kugira ngo zinoze igihe cyo kurutunganya, hashingiwe gusa ku miterere ya buri gishushanyo, ahubwo no ku bwoko bw'ibikoresho bikoreshwa.
Ni gute wakwizeza ko kole ya LED yakize neza?
Iyo kole ya LED yakize neza, ikora ubuso bukomeye kandi budafatana kandi bumeze nk'ikirahure. Ikibazo cyakozwe mbere cyo kuvurwa ku bunini bw'uburebure bw'umuraba ni indwara yitwa ogisijeni. Kubuza ogisijeni kubaho iyo ogisijeni yo mu kirere ibuza inzira ya polymerization ya free-radical ivura kole hafi ya zose za UV. Bituma ubuso bufatana kandi bugakira igice.
