Isakhiwo semolekyuli yeI-UV AbssursNgokwesiqhelo iqulethe iibhondi eziphithileyo okanye amakhonkco anqabileyo, ezinokufunga imitha ye-ultraviolet yamaza athile avelengths (ikakhulu i-Uva kunye ne-UVB).
Xa i-ultraviolet iyohlutha iimolekyuli ze-absorble, i-electroni kwiimolekyuli ezivela kwimo yomhlaba ziye kwimo yochulumanco, ifumana amandla emidlalo ye-ultraviolet.
Emva kokufumana ukukhanya kwe-ultraviolet, imolekyuli ikwimeko enomdla ngamandla aphezulu. Ukuze ubuyele kwiLizwe eliZinzileyo lomhlaba, iimolekyuli ze-Absorbhar ziya kukhupha amandla ngezi ndlela zilandelayo:
Inguquko ye-①non:
I-②fluOrescence okanye phosphorescence: Inxalenye yamandla inokukhutshwa ngendlela yokukhanya okubonakalayo (kunqabile).
Ngokufumana imitha ye-ultraviolet kwaye iguqula ibe ngamandla obushushu, i-absissursbers inciphisa umonakalo ongqalileyo we-Ultraviolet kwizixhobo (ezinjengeeplanga, iingubo) okanye ulusu.
Kwiimveliso zeScutsreen, i-Abssuspsers inokuthintela imitha ye-UV yokungena kulusu kwaye inciphise umngcipheko welanga, ukufota kunye nomhlaza wolusu.
Ii-absesvers zethu ze-UV zilungele i-polymers, iingubo kunye ne-cosmetics. Ukuba ufuna iimveliso, nceda ukhululeke ukunxibelelana nathi, siya kuphendula kwisithuba seeyure ezingama-48.
