Ithiyo2, eyaziwa nangokuthi i-titanium dioxide, i-pigment esetshenziswa kakhulu embonini yephepha. Iwumsebenzi oguquguqukayo osetshenziselwa ukuthuthukisa ukugqama, ukukhanya nokumhlophe kwemikhiqizo yephepha. Enye yezinhlobo ezivame kakhulu ze-titanium dioxide esetshenziswa ekwenzeni iphepha i-anatase titanium dioxide, evame ukukhishwa e-China ngenxa yekhwalithi yayo ephezulu kanye nokusebenza kahle kwezindleko.
Ukusetshenziswa kwe-titanium dioxide ekwenzeni iphepha kunomthelela omkhulu kukhwalithi kanye nokusebenza komkhiqizo wokugcina wephepha. Enye yezinzuzo eziyinhloko zokwengeza i-titanium dioxide ephepheni yikhono layo lokuthuthukisa izici zephepha ezibonakalayo, njengokukhanya nokufiphala. Lokhu kubaluleke kakhulu ekukhiqizeni amaphepha okuphrinta nawokubhala ekhwalithi ephezulu, lapho ukukhanga okubonakalayo kwephepha kubaluleke kakhulu.
Ngaphezu kokuthuthukisa izici zephepha, i-titanium dioxide nayo idlala indima ebalulekile ekuthuthukiseni ukuphrinta nokumunca uyinki kwemikhiqizo yephepha. Ukuba khona kwe-titanium dioxide embotsheni yephepha kusiza ukudala indawo ebushelelezi futhi efanayo, okubalulekile ekuzuzeni imiphumela yokuphrinta yekhwalithi ephezulu. Lokhu kubaluleke kakhulu ekukhiqizeni omagazini, amakhathalogi nezinye izinto eziphrintiwe, lapho ukucaca kwezithombe nombhalo kubaluleke kakhulu.
Ukwengeza, i-titanium dioxide isiza ukuthuthukisa ukuqina okuphelele nokuhlala isikhathi eside kwemikhiqizo yephepha. Ngokwandisa amandla kanye nokumelana nokuguga, i-titanium dioxide isiza ukunweba impilo yephepha, iyenze ifanelekele ukusetshenziswa kwengobo yomlando nokugcinwa isikhathi eside. Lokhu kubaluleke kakhulu ezimbonini ezifana nokushicilela kanye nokugcinwa kwemibhalo, lapho ubude bemikhiqizo yephepha kuyisici esibalulekile.
Lapho kutholwai-anatase titanium dioxidekusuka e-China, izici eziningana zenza kube yisinqumo sokuqala kubakhiqizi bephepha. I-anatase yaseShayina i-titanium dioxide yaziwa ngobumsulwa bayo obuphezulu kanye nekhwalithi ezinzile, okuyenza ibe ukukhetha okuthembekile nokungabizi ekukhiqizeni iphepha. Ngaphezu kwalokho, iChina ingumkhiqizi omkhulu we-titanium dioxide futhi inemboni ezinzile ekwazi ukuhlangabezana nezidingo zemakethe yamaphepha yomhlaba wonke.
Nokho, kubalulekile kubakhiqizi bamaphepha ukuthi baqinisekise ukuthi i-titanium dioxide abayikhipha e-China ihlangabezana nezindinganiso ezidingekayo zokulawula nekhwalithi. Lokhu kubandakanya ukuhambisana nemithethonqubo yezemvelo kanye nokuhambisana nezidingo eziqondene nemboni yephepha. Ngokusebenzisana nabahlinzeki abahloniphekile futhi basebenzise izinyathelo eziphelele zokulawula izinga, abakhiqizi bamaphepha bangaqinisekisa ukuthi i-titanium dioxide esetshenziswa ezinqubweni zabo ihlangabezana nezindinganiso ezidingekayo zokukhiqiza imikhiqizo yephepha ephezulu.
Kafushane, ukusetshenziswa kwe-titanium dioxide, ikakhulukazi i-anatase titanium dioxide evela e-China, kunomthelela omkhulu enqubweni yokwenza iphepha. Kusukela ekuthuthukiseni izici zokubonwa kwephepha kanye nokuphrinta ukuze kwandiswe ukuqina kwalo nempilo yesevisi, i-titanium dioxide idlala indima ebalulekile ekukhiqizeni imikhiqizo yephepha yekhwalithi ephezulu. Ngokuqonda umthelela we-titanium dioxide enqubweni yokukhiqiza iphepha kanye nokutholakala kwabahlinzeki abathembekile, abakhiqizi bephepha bangaqhubeka nokukhiqiza imikhiqizo yephepha ehlangabezana nekhwalithi ephezulu kakhulu nezindinganiso zokusebenza.
