    Uhlobo Oluhle

    I-titanium dioxide iyinto eluhlaza yamakhemikhali angaphili, esetshenziswa kabanzi ekukhiqizweni kwezimboni njengezembozo, amapulasitiki, irabha, ukwenza iphepha, uyinki wokunyathelisa, imicu yamakhemikhali, kanye nezimonyo. I-titanium dioxide inezinhlobo ezimbili zekristalu: i-rutile kanye ne-anatase. I-rutile titanium dioxide, okungukuthi, i-titanium dioxide yohlobo lwe-R; i-anatase titanium dioxide, okungukuthi, i-titanium dioxide yohlobo lwe-A.
    I-Rutile titanium dioxide inezakhiwo ezinhle kakhulu njengokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala, amandla aphezulu, kanye namandla adonsela phansi amancane. Uma iqhathaniswa ne-anatase titanium dioxide, inokumelana nesimo sezulu okuphezulu kanye nomsebenzi ongcono we-photooxidative. Uhlobo lwe-Rutile (uhlobo lwe-R) lunobuningi obungu-4.26g/cm3 kanye ne-refractive index engu-2.72. I-titanium dioxide yohlobo lwe-R inezici zokumelana nesimo sezulu okuhle, ukumelana namanzi futhi akulula ukuphenduka ophuzi. I-Rutile titanium dioxide inezinzuzo eziningi ekusetshenzisweni okuhlukahlukene. Isibonelo, ngenxa yesakhiwo sayo, umbala ewukhiqizayo uzinzile kakhulu ngombala futhi kulula ukuwufaka umbala. Inekhono elinamandla lokufaka umbala futhi ayilimazi indawo engaphezulu. Faka umbala ophakathi, futhi umbala ukhanya, akulula ukuwufiphaza.

    I-titanium dioxide iyinto eluhlaza yamakhemikhali angaphili, esetshenziswa kabanzi ekukhiqizweni kwezimboni njengezembozo, amapulasitiki, irabha, ukwenza iphepha, uyinki wokunyathelisa, imicu yamakhemikhali, kanye nezimonyo. I-titanium dioxide inezinhlobo ezimbili zekristalu: i-rutile kanye ne-anatase. I-rutile titanium dioxide, okungukuthi, i-titanium dioxide yohlobo lwe-R; i-anatase titanium dioxide, okungukuthi, i-titanium dioxide yohlobo lwe-A.
    I-titanium dioxide yohlobo lwe-titanium ingeye-titanium dioxide yezinga lombala, enezici zamandla okufihla aqinile, amandla aphezulu okufaka umbala, ukulwa nokuguga kanye nokumelana okuhle nesimo sezulu. I-Anatase titanium dioxide, igama lamakhemikhali i-titanium dioxide, ifomula yama-molecule i-Ti02, isisindo sama-molecule i-Ti02. Impuphu emhlophe, ukuminyana okuhlobene okungu-3.84. Ukuqina akukuhle njenge-rutile titanium dioxide, ukumelana kokukhanya akukuhle, futhi ungqimba lwe-adhesive kulula ukulucola ngemva kokuhlanganiswa ne-resin. Ngakho-ke, ngokuvamile isetshenziselwa izinto zangaphakathi, okungukuthi, isetshenziselwa kakhulu imikhiqizo engadluli elangeni eliqondile.
