Chidule cha Zinthu Zomwe Zimakhudza Kuchiritsa kwa UV LED

Nyali ya UV ya LED ngati gwero lowunikira wamba, mfundo yake yochiritsa imatanthawuza ma inki a UV pambuyo pa kuyatsa kwa UV kuyambitsidwa ndi chojambula, motero kupanga ma radicals aulere kapena ayoni. Izi ufulu ankafuna kusintha zinthu mopitirira kapena ayoni ndi chisanadze ma polima kapena unsaturated monomers mu awiri chomangira mtanda olumikizira anachita, mapangidwe jini monoma, jini monoma amayamba unyolo anachita kupanga polima zolimba kutali molekyulu.

Pali zinthu zingapo zofunika zomwe zimakhudza kuchiritsa kwa UV LED:

Kuchiritsa zinthu zakuthupi

Kuthamanga kwa machiritso ndi mphamvu yaZida zochiritsira za UV LEDzimadalira kwambiri kuvutika kwa kuwala kuyambitsa mamolekyu mu zipangizo zochiritsira. Kuchiritsa kwa UV kumatsimikiziridwa ndi kugundana pakati pa ma photon ndi mamolekyu. Kuwala kumapangitsa kuti mamolekyu azifalikira mofanana kudzera muzinthuzo. Kuphatikiza pa mawonekedwe a zida zochiritsira, mawonekedwe owoneka bwino ndi a thermodynamic a zida zochiritsira komanso kuyanjana kwawo ndi mphamvu zowunikira zimakhudza kwambiri njira yochiritsira.

Mlingo wa Spectral Absorption

Kuchuluka kwa mphamvu ya kuwala komwe kumatengedwa ndi zokutira za UV pamene akuwonjezeka mu makulidwe kumatchedwa spectral mayamwidwe mlingo. Mphamvu zambiri zimatengedwa pafupi ndi pamwamba, mphamvu zochepa zimasungidwa mu zigawo zakuya. Komabe, izi zimasiyanasiyana malinga ndi mafunde osiyanasiyana. Chiwerengero chonse cha mayamwidwe a spectral chimaphatikizapo zotsatira za zoyambitsa kuwala, zinthu za monomolecular, oligomers, zowonjezera ndi ma pigment.

Kulingalira ndi kubalalitsa

M'malo momayamwa, mphamvu zowunikira zimakhudzidwa ndi kusintha kwa inki, zomwe zimapangitsa kuwunikira ndi kubalalitsidwa. Izi nthawi zambiri zimachitika chifukwa cha matrix kapena ma pigment omwe ali muzinthu zochiritsika. Zinthu izi zimachepetsa kuchuluka kwa mphamvu za UV zomwe zimafika pazozama, koma zimapangitsa kuti machiritso azigwira bwino ntchito pamalo ochitirako.

Mayamwidwe a infrared komanso kutalika koyenera kwa UV

Kutentha kumakhudza kwambiri kuthamanga kwa machiritso, ndipo kukwera kwa kutentha panthawiyi kumathandizanso. Ma inki osiyanasiyana a UV amafunikira mafunde osiyanasiyana a UV kuti achiritsidwe. Posankha chipangizo chochiritsira, ndikofunikira kusankha chomwe chikugwirizana ndi kutalika kwa mafunde ofunikira ndi zokutira za UV. Kugwiritsa ntchito aChipinda chowongolera cha UV LEDndi kutalika koyenera kumapereka zotsatira zabwino zochiritsira.
