Ubume bemolekyuli yeiAbsorber UVihlala iqulathe iibhondi ezidityanisiweyo eziphindwe kabini okanye imisesane enevumba elimnandi, enokufunxa imitha yeultraviolet yobude obuthile (ikakhulu i-UVA kunye ne-UVB).
Xa imitha ye-ultraviolet ikhupha iimolekyuli ezifunxayo, ii-electron ezikwimolekyuli zitshintsha ukusuka kwindawo esemhlabeni ukuya kwimeko echulumancisayo, zifunxa amandla emitha ye-ultraviolet.
Emva kokufunxa ukukhanya kwe-ultraviolet, i-molecule ikwimeko evuyayo enamandla amakhulu. Ukuze ubuyele kwisimo somhlaba esizinzileyo, iimolekyuli ezifunxayo ziya kukhupha amandla ngeendlela ezilandelayo:
① Utshintsho olungenamitha: guqula amandla abe ngamandla obushushu kwaye uwakhulule kwindawo engqongileyo.
②I-Fluorescence okanye i-phosphorescence: inxalenye yamandla inokukhutshwa ngendlela yokukhanya okubonakalayo (ngokungaqhelekanga).
Ngokufunxa imisebe ye-ultraviolet kunye nokuguqula amandla okushisa, i-Absorbers ye-UV inciphisa umonakalo othe ngqo wemitha ye-ultraviolet kwizinto (ezifana neeplastiki, iingubo) okanye isikhumba.
Kwiimveliso zokukhusela ilanga, i-UV absorbers inokuthintela imitha ye-UV ukuba ingangeni esikhumbeni kwaye inciphise umngcipheko wokutshiswa lilanga, ukufota kunye nomhlaza wolusu.
I-Absorber yethu ye-UV ifanelekile kwiipolymers, iingubo kunye nezithambiso. Ukuba ufuna iimveliso, nceda ukhululeke ukudibana nathi, siya kuphendula kwiiyure ezingama-48.
