Izihlungi ze-UV, ezaziwa nangokuthi izihlungi ze-UV noma ama-sunscreens, ziyinhlanganisela esetshenziselwa ukuvikela izinto ezihlukahlukene emiphumeleni eyingozi yemisebe ye-ultraviolet (UV). Esinye salezi zinto zokumunca i-UV yi-UV234, okuyisinqumo esithandwayo sokuhlinzeka ngokuvikeleka emisebeni ye-UV. Kulesi sihloko sizohlola uhla lwama-absorber e-UV futhi sihlole izici ezithile kanye nokusetshenziswa kwe-UV234.

I-spectrum yama-Absorbers e-UV ihlanganisa izinhlobonhlobo zezinhlanganisela eziklanyelwe ukumunca nokuhlakaza imisebe ye-UV. Lezi zinhlanganisela zivame ukusetshenziswa emikhiqizweni efana ne-sunscreen, amapulasitiki, amapende nezindwangu ukuvimbela ukuwohloka nokulimala okubangelwa ukuchayeka kwe-UV. Ama-absorber ama-UV asebenza ngokumunca imisebe ye-UV futhi ayiguqule ibe ukushisa okungenangozi, ngaleyo ndlela ivikela izinto ezisetshenziswayo emiphumeleni eyingozi yemisebe ye-UV.

Ama-absorber ama-UV ahlukaniswe abe izigaba ezahlukene ngokusekelwe ekwakhekeni kwamakhemikhali awo kanye nendlela yokwenza. Ezinye izinhlobo ezivamile zokumunca i-UV zihlanganisa ama-benzophenones, ama-benzotriazoles, nama-triazines. Uhlobo ngalunye lwe-Absorber ye-UV lunezinzuzo ezithile futhi lufanele izinhlelo zokusebenza ezahlukene. Isibonelo, i-UV234 iyisimunyisi se-UV se-benzotriazole esisetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yezindawo zayo ezinhle kakhulu zokuvikela i-UV.

I-UV234 yaziwa ngokusebenza kwayo okuphezulu ekumunceni imisebe ye-ultraviolet, ikakhulukazi kububanzi be-UVB ne-UVA. Lokhu kuyenza ifanelekele ukuhlinzeka ngokuvikelwa kwemisebe ye-UV ebanzi. I-UV234 ivamise ukusetshenziswa ekwenziweni kokuvikela ilanga ukuze kuthuthukiswe amandla omkhiqizo wokuvikela i-UV. Ukwengeza, isetshenziswa kumapulastiki nakuma-coatings ukuvimbela ukuwohloka kwesithombe nokugcina ubuqotho bezinto ezibonakalayo lapho zivezwe elangeni.

Ukusetshenziswa kweUV234azikhawulelwe ekukhiqizweni kwelanga kanye nezingubo zokuzivikela. Ibuye isetshenziswe embonini yendwangu ukunikeza ukumelana kwe-UV ezindwangu kanye nemicu. Ngokuhlanganisa i-UV234 kwezindwangu, abakhiqizi bangakhuphula ukuqina nokuhlala isikhathi eside kwempahla, bayenze ifanelekele izinhlelo zokusebenza zangaphandle lapho ukuchayeka emisebeni ye-UV kungenakugwenywa.

Ngaphezu kwezakhiwo zayo zokumunca i-UV, i-UV234 yaziwa nangokukwazi ukuthwebula izithombe, okuqinisekisa ukuthi ihlala isebenza kahle ngisho nangemva kokuchayeka isikhathi eside elangeni. Lesi sakhiwo sibalulekile ukugcina ukusebenza kwemikhiqizo equkethe i-UV234, njengoba iqinisekisa ukuvikeleka okuhlala isikhathi eside emisebeni ye-UV.

Uma ucubungula izinhlobonhlobo zezimunyisi ze-UV, kubalulekile ukuqonda izidingo ezithile zohlelo lokusebenza kanye nezinga lokuvikelwa kwe-UV elidingekayo. Ama-absorber ama-UV ahlukene ahlinzeka ngamazinga ahlukahlukene okuvikela kwe-UV kanye nokuhambisana nezinto ezihlukile. Ngakho-ke, kubalulekile ukukhetha ezifaneleI-Absorber ye-UVngokusekelwe ekusetshenzisweni okuhlosiwe kanye nezakhiwo ezithile zezinto ezivikelwe.

Kafushane, izinto zokudonsa i-UV zidlala indima ebalulekile ekuvikeleni izinto emisebeni ye-UV elimazayo. I-UV234 iyisimunyisi se-benzotriazole UV esisetshenziswa kabanzi ngezici zayo ezinhle kakhulu zokuvikela i-UV kanye nokuthatha izithombe. Ukuqonda ububanzi bezinqamuleli ze-UV kanye nezakhiwo zazo ezithile kubalulekile ekukhetheni isibambisi se-UV esifaneleka kakhulu sohlelo oluthile. Kungakhathaliseki ukuthi kusezakhiweni zokuvikela ilanga, amapulasitiki, okokunamathela noma izindwangu, izinto zokumunca i-UV ezifana ne-UV234 zinikeza isivikelo esinokwethenjelwa emisebeni ye-UV, okusiza ukukhulisa impilo ende nokusebenza kwezinto ezihlukahlukene.
