I-Titanium dioxide (TiO2) iwumbala omhlophe osebenza ngezindlela ezihlukahlukene osetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa upende, okokunamathela, amapulasitiki nezimonyo. Izakhiwo zayo eziyingqayizivele ziyenza ibe isithako esibalulekile ekuzuzeni umbala oyifunayo, ukufiphala nokukhanya komkhiqizo wakho. Kodwa-ke, ukuze uthole ngokugcwele izinzuzo ze-titanium dioxide, kubalulekile ukuqinisekisa ukuhlakazeka okuphumelelayo ngesikhathi sokufaka isicelo. Ukuhlakazwa okufanele kwe-TiO2 powder nomaukuhlakazeka kwe-titanium dioxidekubalulekile ekwandiseni ukusebenza kwayo kanye nokuzuza imiphumela efiselekayo. Kulesi sihloko sizobheka amathiphu athile okusabalalisa ngempumelelo i-titanium dioxide ukuze kusetshenziswe kahle ukusetshenziswa kwayo ezimbonini ezahlukene.
1. Qonda ukuhlakazwa kwe-titanium dioxide
Ngaphambi kokungena kumathiphu okuhlakazeka okuphumelelayo, kubalulekile ukuqonda umqondo wokuhlakazeka kanye nokubaluleka kwakho ekusetshenzisweni kwe-titanium dioxide. I-Dispersion ibhekisela ekusabalaleni okufanayo kwezinhlayiya ze-TiO2 endaweni efana ne-matrix ewuketshezi noma eqinile. Ukuhlakazwa okufanele kuqinisekisa ukusatshalaliswa okufanayo kwezinhlayiya ze-titanium dioxide, kuvimbela ukuhlangana futhi kukhuthaze ukusebenza kahle komkhiqizo wokugcina.
2. Khetha indlela efanelekile yokuhlakazwa kwe-titanium dioxide
Kunezindlela eziningi zokusabalalisatitanium dioxide, okuhlanganisa ukuhlakazeka okumanzi, ukuhlakazeka okomile, ukwelashwa kwendawo, njll. Ukukhethwa kwendlela yokusabalalisa kuncike ekusetshenzisweni okuqondile kanye nezakhiwo ze-TiO2 dispersion medium. Isibonelo, embonini kapende kanye nezingubo zokumboza, ukuhlakazeka okumanzi kuvame ukwenziwa kusetshenziswa ama-dispersers anesivinini esiphezulu noma izigayo zemidiya ukuze kuzuzwe ukusabalalisa kwezinhlayiyana ezifanayo.
3. Sebenzisa imikhiqizo yekhwalithi ephezulu ye-titanium dioxide
Izinga le-titanium dioxide powder noma ukuhlakazeka kudlala indima ebalulekile ekuzuzeni ukuhlakazeka okuphumelelayo. Imikhiqizo yekhwalithi ephezulu ye-titanium dioxide kufanele iqhamuke kubahlinzeki abahlonishwayo ukuze kuqinisekiswe usayizi wezinhlayiyana ezingaguquki, ukwakheka nokuqedwa kwendawo. Imikhiqizo yekhwalithi ephezulu ye-titanium dioxide ihlakazeka kalula futhi inikeza ukusebenza okuthuthukisiwe ezinhlelweni ezihlukahlukene.
4. Lungiselela ifomula futhi usebenze nemingcele
Ngaphezu kokukhetha indlela elungile yokuhlakazeka kanye nemikhiqizo yekhwalithi ephezulu ye-TiO2, ukuqinisa ukubunjwa kanye nemingcele yenqubo nakho kubalulekile ukuze kuzuzwe ukuhlakazwa okuphumelelayo. Izinto ezifana nokugxila kwe-titanium dioxide, ukukhetha kokuhlakazeka, nezimo zokucubungula (isb, izinga lokushisa, izinga lokugunda) zingathinta kakhulu inqubo yokuhlakazwa. Ngokulungisa ngokucophelela le mingcele, abakhiqizi bangafinyelela ukuhlakazeka okungcono futhi bathuthukise ukusebenza kwe-titanium dioxide emikhiqizweni yabo.
5. Sebenzisa imishini yokusabalalisa ethuthukisiwe
Ukutshala imali emishinini yokusabalalisa ethuthukisiwe kungathuthukisa kakhulu inqubo yokusabalalisa futhi kukhulise ukusetshenziswa kwe-titanium dioxide. Ama-dispersers anesivinini esiphezulu, izigayo zobuhlalu, nama-homogenizers e-ultrasonic yizibonelo zemishini ethuthukisiwe engahlakaza ngempumelelo izinhlayiya ze-TiO2, ngaleyo ndlela ithuthukise ukuvezwa kombala, ukufiphala, nokuqina komkhiqizo wokugcina.
6. Yenza ukulawula izinga kanye nokuhlola
Ukuqinisekisa ukuhlakazeka okungaguquki nempumelelo kwe-titanium dioxide, ukulawulwa kwekhwalithi okuphelele nokuhlolwa kufanele kwenziwe kuyo yonke inqubo yokukhiqiza. Lokhu kuhlanganisa ukuqapha ukusatshalaliswa kosayizi wezinhlayiyana, ukuhlola ukuthuthukiswa kombala, nokuhlola izakhiwo ze-rheological zokuhlakazeka. Ngokusebenzisa izinyathelo eziqinile zokulawula ikhwalithi, abakhiqizi bangakwazi ukuhlonza futhi baxazulule noma yiziphi izinkinga ezihlobene nokuhlakazeka, ngaleyo ndlela bathuthukise ukusebenza komkhiqizo.
Kafushane, ukwandisaukusetshenziswa kwe-titanium dioxidekudinga ukunakwa ngokucophelela kwinqubo yokusabalalisa. Ngokuqonda izimiso zokuhlakazeka, ukukhetha indlela efanele yokuhlakazeka, kusetshenziswa imikhiqizo yezinga eliphezulu ye-titanium dioxide, ukwenza ngcono amafomula kanye nemingcele yenqubo, kusetshenziswa imishini yokuhlakaza ethuthukisiwe, kanye nokulawula ikhwalithi eqinile, abakhiqizi bangafinyelela ukuhlakazwa okuphumelelayo futhi bakhulule amandla aphelele e-titanium. isikhutha. Amandla e-sulphur dioxide asemikhiqizweni yawo. Ukuhlakazwa okusebenzayo akuthuthukisi kuphela ukusebenza kwe-titanium dioxide, kodwa futhi kusiza ukuthuthukisa ikhwalithi iyonke kanye nokusebenza komkhiqizo wokugcina kuzo zonke izimboni.
