Titanium dioxide(Tio2) kuyindlela eguquguqukayo esetshenziswa ezimbonini ezahlukahlukene, kufaka phakathi upende, ukugqoka, amapulasitiki nezimonyo. Izakhiwo zayo ezihlukile zikwenza kube yisithako esibalulekile ekuzuzeni umbala owuthandayo, opacity nokuvikelwa kwe-UV. Kodwa-ke, ukubona amandla aphelele we-tio2 powder, ukuhlakazeka okusebenzayo kubalulekile. Ukusabalalisa okufanele kuqinisekisa ngisho nokusatshalaliswa kanye nokusetshenziswa okuphezulu kwemibala, okuholela ekugcinweni kwezindleko kanye nokusebenza okuthuthukile komkhiqizo.
Enye yezinselelo ezibalulekile ekusebenziseni i-Tio2 powder ithola ukuhlakazeka okufanayo. Imiphumela yokuhlakazeka kabi kwemibala engalingani, inciphise opacity, kanye nekhwalithi yomkhiqizo encishisiwe. Ukubhekana nalolu daba, abakhiqizi kanye nabaphenyi bebelokhu behlola amasu amasha okwenza ukusetshenziswa kwe-Tio2 powder ngobuchwepheshe obusebenzayo bokusakaza.
Indlela ephumelelayo yokwenza ngcono ukuhanjiswa kwe-Tio2 ukusebenzisa imishini yokuhlakazeka ethuthukile. Abasakazi bejubane eliphakeme, ama-bead mill, kanye nama-homogenizer e-ultrasonic asetshenziswa kakhulu amathuluzi okuthola ukuncishiswa kosayizi obuhle nokusatshalaliswa kweyunifomu kumatikuletsheni ahlukahlukene. Lawa madivayisi asiza ekuqhekekeni kwama-agglogerates kanye nokumanzisa izinhlayiya ze-tio2, ngaleyo ndlela athuthukise ukuhlakazwa kanye nokwenza umkhiqizo wokugcina.
Ngaphezu kwemishini esezingeni eliphakeme, ukukhetha ukuhlakazwa okulungile nakho kubalulekile nokwandisa ukusetshenziswa kwe-tio2 powder. Abasakazi, njengezinto ezisetshenziswayo nezithasiselo ze-polymer, badlala indima ebalulekile ekuqiniseni ukusabalalisa, ukuvimbela ukuphinde kwenziwe kabusha kanye nokuqhakambisa ukunamathela ku-subthesion. Ngokukhetha ngokucophelela ukuhlakazwa okufanelekile ngokususelwa kwisicelo esithile kanye matrix, abakhiqizi bangafinyelela ukusakazwa okusebenzayo kwe-tio2 powder futhi bathuthukise ukusebenza kwawo jikelele.
Ngaphezu kwalokho, inhlanganisela yobuchwepheshe bokwelashwa komhlaba ingathinta kakhulu ukuhlakazeka kanye nokusetshenziswa kwe-tio2 powder. Amasu wokuguqulwa komhlaba, njengokwelashwa kwe-lisane kanye ne-alumina coating, kungathuthukisa ukuhambisana kwe-tio2 enama-matric ahlukene, ngaleyo ndlela kuthuthukise ukuhlakazeka kanye nokunamathela. Lezi zindlela zokwelapha ezingaphezulu zisiza ukuthuthukisa ukumelana nesimo sezulu nokuqina kwemikhiqizo equkethe i-tio2-equkethe, kubenza balungele izinhlelo zokusebenza zangaphandle.
Esinye isici sokwenza kahle ukusetshenziswa kweI-tio2 powderukuthuthukiswa kwezixazululo ezenziwe ngezifiso zokuhlakazeka kwezicelo ezithile. Izimboni nemikhiqizo ehlukene kungadinga amasu ahlukile wokuhlukana ukuze afeze ukusebenza kahle. Isibonelo, ku-Paints kanye ne-Coatings Industry, iTitanium Dioxide Disprings ehlelwe ngama-Rheology Modifiers kanye nokugcina ukuqina kungathuthukisa ukugeleza kwezakhiwo futhi kuvikele ukuxazulula, ukuqinisekisa umbala ongaguquki kanye nokuhlanganiswa. Ngokunjalo, embonini yePlastiksi, ukwakhiwa kwe-masterbatch nge-Tio2 Ukuhlakazeka kwe-Tio2 kungathuthukisa izakhiwo zemishini neze-Optical zomkhiqizo wokugcina.
Ngokufingqa, ukwenza kahle ukusetshenziswa kwe-tio2 powder ngokusebenzisa ukusabalaliswa okusebenzayo kubalulekile ukukhulisa izinzuzo zayo ezinhlobonhlobo zezicelo. Ngokusebenzisa imishini yokuhlakazwa okuthuthukile, ukhetha ama-dispersants afanele, ukuhlanganisa ubuchwepheshe bokwelashwa komhlaba kanye nokwenza ngezifiso izixazululo zokuhlakazeka, abakhiqizi bangathola ukusakazwa okufanayo kwe-tio2 futhi bathuthukise ukusebenza kwawo kumkhiqizo wokugcina. Lawa masu awagcini nje kuphela ukonga izindleko futhi athuthukise ikhwalithi yomkhiqizo, kepha futhi avelele indlela yokuqhubeka nokuqamba kanye nentuthuko ye-Titanium Dioxide-based Izinto ezimakethe zomhlaba.
