I-Titanium Dioxide (Tio2) iyindawo ehlukahlukene etholile izicelo ezimbonini ezisukela kwizimonyo eziya ekudleni nasemikhakheni. Phakathi kwamabanga ahlukahlukene, ibanga lemithi ye-titonium dioxide ngenxa yokuhlanzeka kwayo okuphezulu kanye nezindinganiso ezijwayelekile zokukhiqiza. Kule bhulogi, sizohlola ukwakheka kanye nezinto ezingavuthiwe ze-titanium dioxide, ngokugxila okuthile kwebanga le-titanium dioxide akhiqizwa ngumholi wezimboni Kewei.
Ukuqonda i-titanium dioxide
I-Titanium dioxide i-titanium oxirium ngokwemvelo eyaziwa ngombala wayo omhlophe okhanyayo kanye ne-opacity enhle kakhulu. Ikhona ngamafomu ahlukahlukene ama-crystalline, okuvame kakhulu okungukuthi anatase kanye rutile. Ibanga lezemithititanium dioxideKukhiqizwe yi-Kewei yi-anatase ekhethekile engacaciswanga, ethandwa ngokusebenza kwayo okuphezulu kuzicelo zezokwelapha.
Ukwakheka kwe-titanium dioxide
Isakhiwo se-titanium dioxide sibonakaliswa yilungiselelo laso le-crystal. Ngefomu le-anatase, titanium dioxide inesakhiwo se-tetragonal crystal, esinikeza izakhiwo ezihlukile ze-optical. Lesi sakhiwo sivumela ukusakazeka okuphezulu okuphezulu, okwenza kube yi-pigment enhle yezinhlelo ezahlukahlukene. Ubumsulwa be-titanium dioxide busína, njengoba ukungcola kungathinta ukusebenza kwawo nokuphepha kwayo ezinhlelweni zezemithi.
Izinto zokusetshenziswa kanye nenqubo yokukhiqiza
I-Kewei isebenzisa inqubo esezingeni eliphezulu se-sulfate ukukhiqiza ibanga le-titanium ye-thitanium. Indlela ifaka ukusabela kwezinto zokusetshenziswa ezinemininingwane ye-titanium - njenge-Ilmenite noma i-rutile) nge-sulfuric acid. I-titanium sulfate ephumela i-addrolyzed yabe selikhiqizwa i-titanium dioxide. Le nqubo ayigcini ngokuqinisekisa ubumsulwa obuphezulu kuphela, kepha futhi ihlangabezana nezindinganiso zemvelo, ukuzibophezela kwe-Kewei kuthatha ngokungathi sína.
Izinto ezingavuthiwe ezisetshenziselwa ukukhiqizwa kweTitanium Dioxide zikhethwe ngokucophelela futhi zihlangabezana nalezo ezisethwe yi-United States PharmacopoEIa (USP), i-European Pharmacoepoeia (EP) nePharmacopoeia (jp) ne-Japarsese Pharmacopoeia (jp). Lokhu kuqinisekisa ukuthi umkhiqizo wokugcina uphephile ukuze usetshenziswe ezinhlelweni ezahlukahlukene zezokwelapha, kufaka phakathi i-excipont ekwakhiweni kwezidakamizwa.
Isicelo embonini yezemithi
Ibanga le-Titanium Dioxide lisetshenziswa kabanzi embonini ngenxa yokungabi nobuthi kanye nokuqina okuhle. Inokusetshenziswa okuhlukahlukene, njenge-pigment kumathebulethi nama-caplule, ukuhlinzeka ukubukeka okuhle kwe-aesthetical ngenkathi kuthuthukisa ukuqina komkhiqizo. Ngaphezu kwalokho, inezakhiwo zesikrini esisebenzayo se-sunnscreen kumakhilimu namafutha, ukuqinisekisa ukuthi izithako ezisebenzayo aziwonakaliswa ukuvezwa kokukhanya.
Ukuzibophezela kukaKewei kwikhwalithi nokwenziwa okusha kukwenze kwaba ngumholi ekukhiqizweni kweSulfuric Acid Titanium Dioxide. Ngemishini yokukhiqiza yombuso kanye nokugxila kokusimama kwemvelo, i-Kewei ayihlangene kuphela kodwa futhi idlula amazinga ezimboni, ihlinzeka ngezinkampani ezenzakadeni ngomthombo onokwethenjelwa we-titanium dioxide ephezulu.
Ekuphetheni
Ngamafuphi, isakhiwo nezinto zokwakha ezivuthiwe zebanga le-titanium dioxide zidlala indima ebalulekile ekusebenzeni kwayo kanye nokuphepha emikhakheni. Inqubo yokuzibophezela yaseKewei ethuthukile kanye nokuzibophezela kwekhwalithi yekhwalithi yaqinisekisa ukuthi i-titanium dioxide yayo ihlangabezana nezindinganiso eziphakeme kakhulu zezimboni. Njengoba ukufunwa kwezithako zokuhlanzeka okuphezulu kuyaqhubeka ukukhula, ukuqonda ubulukhuni be-titanium dioxide ukukhiqizwa kwezemithi kubalulekile ezinkampanini ezenza imithi ezifuna ukuhlinzeka abathengi ngemikhiqizo ephephile nephumelelayo. Noma ngabe ungumkhiqizi noma umthengi, ukubaluleka kwebanga le-titanium dioxide alikwazi ukungabukelwa phansi njengoba kuhlala kuyingxenye ebalulekile yomphakathi wezokwelapha.
