Xa ucingatitanium dioxide, into yokuqala enokuthi ifike engqondweni kukusetyenziswa kwayo kwi-sunscreen okanye ipeyinti. Nangona kunjalo, le khompawundi inemisebenzi emininzi ikwadlala indima ebalulekileyo kushishino lwamaphepha. I-Titanium dioxide sisibala esimhlophe esisoloko sisetyenziselwa ukuqinisa ukuqaqamba kunye nokungafihli kweemveliso zephepha. Kule bhulogi, siza kuhlolisisa ukubaluleka kwe-titanium dioxide kwimveliso yephepha kunye nefuthe layo kumgangatho wemveliso yokugqibela.
Esinye sezizathu eziphambili zokufaka i-titanium dioxide ephepheni kukwandisa ubumhlophe bephepha. Ngokudibanisa le pigment kwipulp yephepha, abavelisi banokufezekisa imveliso yokugqibela eqaqambileyo, ekhangeleka ngakumbi. Oku kubaluleke kakhulu kwizicelo apho iphepha lisetyenziselwa ukuprinta, njengoko umphezulu oqaqambileyo ubonelela ngokungafaniyo kunye nokuguquguquka kombala. Ukongeza, ubumhlophe obuphuculweyo bunokunika amaxwebhu, ukupakishwa, kunye nezinye izinto ezisekwe ephepheni imbonakalo yobuchwephesha kunye nekhazimlisiweyo.
Ngaphandle kokwandisa ubumhlophe, i-titanium dioxide ikwanceda ekwandiseni ukukhanya kwephepha. I-Opacity ibhekisela kwiqondo apho ukukhanya kuvaliwe ukuba kudlule iphepha, kwaye luphawu olubalulekileyo lwezicelo ezifuna ukukhusela umxholo kwimithombo yokukhanya yangaphandle. Ngokomzekelo, kwizinto zokupakisha, i-opacity ephezulu inokunceda ukugcina ingqibelelo yemveliso epakishwe ngokunciphisa ukukhanya kokukhanya. Ukongezelela, kwizicelo zokushicilela, ukunyuka kwe-opacity kunokuthintela umboniso, ukuqinisekisa ukuba umxholo kwelinye icala lephepha awuphazamisi ukufunda kwelinye icala.
Enye inzuzo ebalulekileyo yokusebenzisatitanium dioxide ephepheniimveliso kukuba nako ukomeleza ukuqina kwephepha kunye nokumelana nokuguga. Ubukho be-titanium dioxide bunceda ukukhusela iphepha kwimiphumo eyingozi yemitha ye-ultraviolet, enokubangela ukuba i-yellowing kunye nokuwohloka kwexesha. Ngokubandakanya le pigment, abavelisi bephepha banokwandisa ubomi beemveliso zabo, benze ukuba bafaneleke ngakumbi ukusetyenziswa kovimba kunye nokugcinwa kwexesha elide.
Kubalulekile ukuba uqaphele ukuba ukusetyenziswa kwe-titanium dioxide ekwenzeni iphepha kufuneka kuhambelane nemigangatho yokulawula kunye nezikhokelo zokuqinisekisa ukhuseleko lwazo kubathengi kunye nokusingqongileyo. Njengayo nayiphi na imichiza, abavelisi kufuneka babambelele kumanyathelo angqongqo olawulo lomgangatho kwaye bathobele imimiselo efanelekileyo ukunciphisa nayiphi na imingcipheko enokubakho enxulumene nokusetyenziswa kwabo.
Ngamafutshane, i-titanium dioxide idlala indima ebalulekileyo ekwandiseni umtsalane wembonakalo, ukungafihli, kunye nokuqina kweemveliso zephepha. Ikhono layo lokuphucula ubumhlophe, ukwandisa i-opacity kunye nokuthintela ukuguga kwenza kube yinto eyongezelelweyo ebalulekileyo kwishishini lephepha. Njengoko imfuno yabathengi yemveliso yephepha ephezulu iqhubeka nokukhula, indima ye-titanium dioxide ekuvelisweni kwephepha inokuhlala ibalulekile, inceda ukuvelisa izinto zephepha ezikumgangatho ophezulu kunye nezihlala ixesha elide.
