I-Titanium dioxideI-(TiO2) iwumbala omhlophe oguquguqukayo futhi osetshenziswa kabanzi owaziwa ngokugqama okukhethekile kanye nenkomba ephezulu yokucwebezela. Isetshenziswa kakhulu ezintweni ezahlukahlukene ezihlanganisa amapende, ama-coatings, amapulasitiki nezimonyo. Ukuze ubone amandla aphelele e-TiO2 powder, kubalulekile ukuqonda izinqubo ezingcono kakhulu zokusetshenziswa kwayo nokuhlakazeka.
Okukodwa okuyinhlokoukusetshenziswa kwe-titanium dioxideisekwenzeni amapende nama-coatings. I-TiO2 powder ibaluleke kakhulu ngekhono layo lokuhlinzeka ngokungabonakali okuhle nokumhlophe emikhiqizweni eqediwe. Kodwa-ke, ukuze kuzuzwe ukusebenza kahle, kubalulekile ukuqinisekisa ukuthi izinhlayiya ze-TiO2 zihlakazeka ngokufanelekile kupende noma ekwakhiweni kokunamathela. Lokhu kungafezwa ngokusebenzisa amasu okuhlakazeka kwekhwalithi ephezulu ye-titanium dioxide, njengokuxutshwa kwe-shear ephezulu noma ukugaya imidiya, okusiza ukuhlukanisa ama-agglomerate nokuqinisekisa ukuthi umbala wombala usabalaliswa ngokulinganayo ngaphakathi kwe-matrix.
Ngaphandle kwamapende nama-coatings, i-titanium dioxide isetshenziswa kakhulu embonini yepulasitiki. Uma uhlanganisa i-TiO2 powder ekwakhekeni kwepulasitiki, kubalulekile ukunaka usayizi wezinhlayiyana ze-pigment kanye nokwelashwa kwendawo. Usayizi wezinhlayiyana ezincane kanye nokwelashwa kwendawo kungathuthukisa ukusakazeka kwe-TiO2 ku-matrix yepulasitiki, ngaleyo ndlela kuthuthukise ukukhanya nokuvikeleka kwe-UV. Ukwengeza, izindlela ezifanele zokuhlanganisa nokucubungula zibalulekile ukuze kuqinisekiswe ukuthi ama-pigments ahlakazeka ngokulinganayo kuyo yonke inhlaka yepulasitiki.
Okunye ukusetshenziswa okubalulekile kwe-titanium dioxide kusembonini yezimonyo. I-Titanium dioxide powder ivame ukusetshenziswa kuma-sunscreens njengesihlungi se-UV esisebenza kahle kakhulu. Ukuze kuzuzwe izinga elifiswayo lokuvikela ilanga, kubalulekile ukuthi izinhlayiya ze-TiO2 zihlakazwe ngokulinganayo kufomula yokuvikela ilanga. Lokhu kungafinyelelwa ngokusebenzisa imishini ekhethekile yokuhlakaza kanye nenqubo yokuxuba ngokuphelele, esiza ukuvimbela ukwakheka kwama-agglomerates futhi iqinisekise nokusatshalaliswa kwezingulube.
Uma usebenzisaI-TiO2 powder, kubalulekile ukucabangela izidingo ezithile zohlelo oluhlosiwe. Izimboni ezahlukene kanye nokwakheka kungase kudinge ukuhlakazwa okuhlukile nezindlela zokufaka isicelo. Isibonelo, ezinhlelweni ezisekelwe emanzini, ukusetshenziswa kwe-ejenti yokumanzisa kanye ne-dispersing kungasiza ukuthuthukisa ukuhlakazeka kwezinhlayiya ze-TiO2. Ngokufanayo, ezinhlelweni ezisekelwe ku-solvent, ukukhetha kobuchwepheshe be-solvent kanye nokusabalalisa kungaba nomthelela omkhulu ekusebenzeni kwe-pigment.
Kafushane, ukuvula amandla e-TiO2 powder kudinga ukuqonda okuphelele kokusebenza kwayo kanye nemikhuba emihle yokusabalalisa. Kungakhathaliseki ukuthi isetshenziselwa upende, okokunamathela, amapulasitiki noma izimonyo, amasu afanele okusabalalisa abalulekile ekuqinisekiseni ukusebenza kahle kwe-titanium dioxide. Ngokugxila ezicini ezifana nobukhulu bezinhlayiyana, ukwelashwa kwendawo kanye nezindlela zokusabalalisa, abakhiqizi bangakwazi ukukhulisa izinzuzo ze-TiO2 powder ekubunjweni kwabo kanye nemikhiqizo.
