Emhlabeni wokunakekelwa kwesikhumba, kunezithako ezingenakubalwa ezithembisa uhla lwezinzuzo. Isithako esinjalo esiye sanakwa eminyakeni yamuvaamafutha i-titanium dioxide ehlakazekile. Le mineral enamandla yenza amagagasi embonini yobuhle ngekhono layo lokuhlinzeka ngokuvikeleka kwelanga okuphumelelayo futhi ithuthukise ikhwalithi yonke yemikhiqizo yokunakekelwa kwesikhumba.
Uwoyela ohlakaziwe i-titanium dioxide wuhlobo lwe-titanium dioxide oluye lwaphathwa ngokukhethekile ukuze luhlakazwe kumafomula asekelwe kuwoyela. Lokhu kusho ukuthi ingafakwa kalula emikhiqizweni ehlukahlukene yokunakekelwa kwesikhumba, okuhlanganisa okhilimu, ama-lotions nama-serum. Enye yezinzuzo eziyinhloko zokusebenzisa amafutha ahlakazekiletitanium dioxide esikhumbeniimikhiqizo yokunakekelwa yikhono layo lokuhlinzeka ngokuvikelwa kwelanga okubanzi.
Lapho isetshenziswa esikhumbeni, i-titanium dioxide ehlakazekile ngowoyela yenza umgoqo wokuvikela osiza ukuvikela isikhumba emiphumeleni eyingozi yemisebe ye-UVA ne-UVB. Lokhu kusiza ekuvimbeleni ukushiswa yilanga, ukuguga ngaphambi kwesikhathi, futhi kunciphisa ngisho namathuba okuba nomdlavuza wesikhumba. Ngokungafani nemithi yokuvikela ilanga ekwazi ukucasula isikhumba esibucayi, i-titanium dioxide esakazwe ngamafutha imnene futhi ayicasuli, iyenza ifanelekele zonke izinhlobo zesikhumba.
Ngaphezu kwezakhiwo zayo zokuvikela ilanga, uwoyela-ahlakazekiletitanium dioxideinikeza uhla lwezinye izinzuzo esikhumbeni. Inezici zemvelo zokulwa nokuvuvukala ezisiza ukudambisa nokuthulisa isikhumba esithukuthele. Lokhu kuyenza ibe isithako esifanelekile semikhiqizo eyenzelwe isikhumba esibucayi noma esinezinduna.
Ukwengeza, i-titanium dioxide ehlakazekile kawoyela ine-high refractive index, okusho ukuthi ingasiza ekuhlakazeni nasekuboniseni ukukhanya kude nesikhumba. Lokhu kunganikeza isikhumba ukubukeka okulinganayo, okukhazimulayo, kusenze sibe isithako esidumile emikhiqizweni eklanyelwe ukunikeza ukukhanya kwemvelo.
Enye inzuzo kawoyela ehlakazekile i-titanium dioxide yikhono layo lokuthuthukisa ukuthungwa nokuzwakala kwemikhiqizo yokunakekelwa kwesikhumba. Inokwakheka okubushelelezi, okusilika okusiza ukunikeza okhilimu namaloshini umuzwa wokunethezeka nokuthambile. Lokhu kuthuthukisa ulwazi olunzulu ngomsebenzisi futhi kwenza imikhiqizo yokunakekelwa kwesikhumba ijabulele ukuyisebenzisa.
Uma uthenga imikhiqizo yokunakekelwa kwesikhumba equkethe uwoyela ohlakaziwe i-titanium dioxide, kubalulekile ukubheka amafomula ekhwalithi ephezulu asebenzisa lesi sithako ekugxiliseni okusebenzayo. Bheka imikhiqizo enokuvikelwa elangeni okubanzi futhi elungele uhlobo oluthile lwesikhumba.
Sengiphetha, i-titanium dioxide ehlakazekile kawoyela iyisithako esisebenza ngezindlela eziningi nesisebenzayo esihlinzeka ngezinzuzo eziningi esikhumbeni. Kusukela ekunikezeni isivikelo elangeni kuya ekuthuthukiseni ukuthungwa kwemikhiqizo yokunakekelwa kwesikhumba, le minerali enamandla iyisengezo esibalulekile kunoma iyiphi inqubo yokunakekela isikhumba. Kungakhathaliseki ukuthi ufuna okokuvikela ilanga okungeke kucasule isikhumba sakho noma ukhilimu wobuso obuwubukhazikhazi obuhlinzeka ngokukhazimula kwemvelo, i-titanium dioxide ehlakazekile kawoyela iyisithako okufanele ube nesithako okufanele sinakwe.
