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 burebure 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.
Kubuza umwuka wa ogisijeni bigaragara cyane mu bikorwa bidafite imbogamizi kuri ogisijeni yo mu kirere. Urugero, kubuza umwuka wa ogisijeni byaba bibi cyane mu gukoresha irangi risanzwe rikoreshwa mu gusiga umwuka ufunguye kurusha uko byaba bimeze mu gushyira kole hagati y’ibirahure.
Ni izihe nyungu zimwe na zimwe z’umutekano w’ibikoresho bikoresha LED mu gupima ikirere ugereranije n’ibya UV?
Amatara ya UV ashobora guteza ikibazo cy’umutekano kuko ashobora gutera ubushye bw’uruhu n’imvune mu maso; nubwo amatara ya LED akenera gukoreshwa hamwe n’ibikoresho byo kwirinda byihariye, ntabwo atera ibyago nk’ibya bagenzi bawo bavura UV.
Ni izihe sisitemu zidasanzwe Master Bond itanga ubwo buvuzi hakoreshejwe itara rya LED?
Serivise ya Master Bond LED 400 itanga imiterere itandukanye y’ubuhanga kandi bitewe n’urwego rwayo, ishobora gukoreshwa mu guhuza, gufunga no gusiga. Igicuruzwa gishya muri uru rukurikirane ni LED405Med.
