Isakhiwo samangqamuzanaAma-Absorbers we-UVngokuvamile iqukethe amabhondi amabili ahlanganisiwe noma izindandatho ezinephunga elimnandi, ezingamunca imisebe ye-ultraviolet yobude obuthile (ikakhulukazi i-UVA ne-UVB).
Lapho imisebe yeultraviolet ikhanyisa amamolecule amunca, amaelectron akumamolecule ayashintsha esuka endaweni engaphansi aye endaweni yenjabulo, amunca amandla emisebe ye-ultraviolet.
Ngemva kokumunca ukukhanya kwe-ultraviolet, i-molecule isesimweni sokujabula esinamandla amakhulu. Ukuze ubuyele esimweni somhlaba esizinzile, ama-molecule adonsayo azokhipha amandla ngezindlela ezilandelayo:
① Uguquko olungashisi: guqula amandla abe amandla okushisa futhi uwakhulule aye endaweni ezungezile.
②I-Fluorescence noma i-phosphorescence: ingxenye yamandla ingase ikhishwe ngendlela yokukhanya okubonakalayo (akuvamile).
Ngokumunca imisebe ye-ultraviolet futhi iyiguqule ibe amandla okushisa, izinto ezimunca ama-UV zinciphisa ukulimala okuqondile kwemisebe ye-ultraviolet ezintweni (njengamapulasitiki, okokunamathela) noma esikhunjeni.
Emikhiqizweni yokuvikela ilanga, izinto zokumunca i-UV zingavimbela imisebe ye-UV ukuthi ingangeni esikhunjeni futhi yehlise ingozi yokushiswa yilanga, ukuthwebula izithombe kanye nomdlavuza wesikhumba.
Ama-absorber ethu e-UV afanele ama-polymers, okokumboza nezimonyo. Uma udinga imikhiqizo, sicela ukhululeke ukuxhumana nathi, sizophendula kungakapheli amahora angama-48.
