I-Titanium dioxide, eyaziwa njengeI-TiO2, yikhompawundi eguquguqukayo kwaye eguquguqukayo enoluhlu olubanzi lwezicelo kwiindidi ezahlukeneyo zamashishini. Iimpawu zayo ezizodwa zenza ukuba ibe yinto ebalulekileyo kwiimveliso ezininzi, ukusuka kwiipeyinti kunye neengubo zokuthambisa kunye nezongezo zokutya. Kweli nqaku, siza kuhlolisisa izicelo ezininzi ze-titanium dioxide, sigxininise ekusebenziseni kwayo kwii-dispersions kunye neefom ze powder.
Esinye sezona zicelo ziqhelekileyo ze-titanium dioxide kukuveliswa kwepeyinti kunye neengubo. Ngenxa yesalathisi esiphezulu se-refractive kunye neempawu ezigqwesileyo zokusabalalisa ukukhanya, i-titanium dioxide iyisithako esibalulekileyo ekubunjweni komgangatho ophezulu we-coating, ukubonelela nge-opacity, ukukhanya kunye nokukhuselwa kwe-UV. Ikhono layo lokusabalalisa ngokulinganayo kwimiqulu yepeyinti yenza kube yinto efanelekileyo yokufezekisa umbala ohambelanayo kunye nokugubungela.
Ukongeza kwiipeyinti, i-titanium dioxide isetyenziswa ngokubanzi kwimveliso yeplastiki, isebenza njenge-agent emhlophe kunye ne-opacifier. Ukusabalalisa kwayo kwiifom zeplastiki kunceda ukuphucula ukukhanya kunye nokuqina kweemveliso zeplastiki, okwenza ukuba zilungele uluhlu olubanzi lwezicelo ezivela kwizinto zokupakisha kwiimveliso zabathengi.
Ukongezelela, i<em>titanium dioxide yeyona nto iphambili kwishishini lezithambiso, apho isetyenziselwa ukwenza izinto zokuzikhusela elangeni, izinto zokunyamekela ulusu nezithambiso. Ukukwazi ukubonakalisa kunye nokusasaza imitha ye-UV yenza ukuba ibe yinto esebenzayo kwi-sunscreen ukukhusela kwimitha ye-UV eyingozi. Kukhathalelo lwesikhumba kunye nezithambiso, i-titanium dioxide ixabiswa ngokukwazi kwayo ukubonelela ngokugudileyo, nokugubungela kunye neempawu zayo ezibonisa ukukhanya, ezinceda ukudala inkangeleko eqaqambileyo, yobutsha.
Kukutya kunye namayeza, i-titanium dioxide isetyenziswa njengesongezo sokutya kunye nombala. I<em>titanium dioxide ewumgubo idla ngokugalelwa ekutyeni okufana neelekese, iimveliso zobisi neepilisi ukuze kuphuculwe inkangeleko kunye nokumila kwazo. I-dispersibility yayo kwi-liquid kunye ne-formulation eqinile yenza isithako esiguquguqukayo ukufezekisa umbala ofunekayo kunye ne-opacity kwiindidi zokutya kunye nezicelo zamachiza.
Kwimveliso,titanium dioxide dispersionsidlala indima ebalulekileyo ekuvelisweni komgangatho ophezulu wokutyabeka kwiimoto, i-aerospace kunye ne-industrial applications. Ikhono layo lokwenza i-dispersions ezinzileyo kwiintlobo ezahlukeneyo ze-solvents kunye ne-resins yenza ukuba ibe yinto ebalulekileyo kwi-coating formulations, inika ukuqina okugqwesileyo, ukuchasana kwemozulu kunye nokukhuselwa kwe-corrosion.
Ukuqukumbela, ukuguquguquka kwe-titanium dioxide kubonakala kwiinkqubo zayo ezahlukeneyo kumashishini amaninzi. Nokuba ikwimo yokusasazwa okanye umgubo, i-titanium dioxide idlala indima ebalulekileyo ekuphuculeni iipropati kunye nokusebenza kweemveliso ukusuka kwiipeyinti kunye nezaleko ukuya kwizinto zokuthambisa kunye nezongezo zokutya. Indibaniselwano yayo ekhethekileyo yeepropathi zamehlo, iikhemikhali kunye nezomzimba ziyenza ibe sisithako esiyimfuneko kwizicelo ezingenakubalwa, ezinegalelo kwinkqubela phambili nakwizinto ezintsha kumashishini ahlukeneyo.
