Ithio2, ekwaziwa ngokuba yititanium dioxide, sisibala sebala esisetyenziswa kakhulu kwishishini lephepha. Yimathiriyeli eguquguqukayo esetyenziselwa ukunyusa ukuqaqamba, ukungafihli kunye nobumhlophe beemveliso zephepha. Enye yeendlela eziqhelekileyo ze-titanium dioxide ezisetyenziswa ekwenzeni iphepha yi-anatase titanium dioxide, ehlala ifunyenwe e-China ngenxa yomgangatho ophezulu kunye nokusebenza kakuhle kweendleko.
Ukusetyenziswa kwe-titanium dioxide ekwenzeni iphepha kunempembelelo ebalulekileyo kumgangatho jikelele kunye nokusebenza kwemveliso yephepha lokugqibela. Enye yeenzuzo eziphambili zokongeza i-titanium dioxide ephepheni kukukwazi ukuphucula iimpawu ze-optical zephepha, ezifana nokukhanya kunye nokungabonakali. Oku kubaluleke kakhulu ekuveliseni amaphepha akumgangatho ophezulu wokuprinta nokubhala, apho isibheno esibonakalayo sephepha sibalulekile.
Ukongeza ekuphuculeni iimpawu ze-optical zephepha, i-titanium dioxide nayo idlala indima ebalulekileyo ekuphuculeni ukuprintwa kunye ne-inki yokufunxa iimveliso zephepha. Ubukho be-titanium dioxide kwi-coating yephepha kunceda ukudala indawo egudileyo kunye nefanayo, into ebalulekileyo ekufezekiseni iziphumo zokushicilela ezikumgangatho ophezulu. Oku kubaluleke kakhulu kwimveliso yeemagazini, iikhathalogu kunye nezinye izinto eziprintiweyo, apho ukucaca kwemifanekiso kunye nesicatshulwa kubaluleke kakhulu.
Ukongeza, i-titanium dioxide inceda ukuphucula ukuqina kunye nexesha elide lemveliso yephepha. Ngokunyusa amandla kunye nokuchasana nokuguga, i-titanium dioxide inceda ukwandisa ubomi bephepha, iyenze ilungele ukusetyenziswa kwe-archival kunye nokugcinwa kwexesha elide. Oku kubaluleke ngakumbi kumashishini afana nokupapasha kunye nokugcinwa kwamaxwebhu, apho ixesha elide leemveliso zephepha liyinto ebalulekileyo.
Xa kufunwai-anatase titanium dioxideukusuka eChina, izinto ezininzi zenza ukhetho lokuqala kubenzi bephepha. I-anatase yaseTshayina i-titanium dioxide iyaziwa ngokucoceka kwayo okuphezulu kunye nomgangatho ozinzile, okwenza kube yinto ethembekileyo kunye neendleko zokukhetha ukuveliswa kwephepha. Ukongeza, iTshayina ngumvelisi ophambili we-titanium dioxide kwaye ineshishini elizinzileyo elikwaziyo ukuhlangabezana neemfuno zentengiso yephepha yehlabathi.
Nangona kunjalo, kubalulekile ukuba abavelisi bephepha baqinisekise ukuba i-titanium dioxide abayifumana e-China ihlangabezana nemigangatho yolawulo kunye nomgangatho oyimfuneko. Oku kuquka ukuthotyelwa kwemigaqo yokusingqongileyo kunye nokuthotyelwa kweemfuno ezithe ngqo kwishishini lephepha. Ngokusebenzisana nabanikezeli abathembekileyo kunye nokuphumeza amanyathelo okulawula umgangatho ngokucokisekileyo, abavelisi bamaphepha banokuqinisekisa ukuba i-titanium dioxide esetyenziswa kwiinkqubo zabo ihlangabezana nemigangatho efunekayo yokuvelisa iimveliso zephepha eziphezulu.
Isishwankathelo, ukusetyenziswa kwe-titanium dioxide, ngakumbi i-anatase titanium dioxide evela eChina, inempembelelo enkulu kwinkqubo yokwenza iphepha. Ukusuka ekuphuculeni iipropathi zephepha kunye nokuprintwa ekwandiseni ukuqina kwayo kunye nobomi benkonzo, i-titanium dioxide idlala indima ebalulekileyo ekuveliseni iimveliso zephepha ezikumgangatho ophezulu. Ngokuqonda impembelelo ye-titanium dioxide kwinkqubo yokwenziwa kwephepha kunye nokukhangela kubathengisi abathembekileyo, abavelisi bephepha banokuqhubeka nokuvelisa iimveliso zephepha ezihlangabezana nomgangatho ophezulu kunye nemigangatho yokusebenza.
