I-Titanium dioxide (TiO2) iwumbala omhlophe oguquguqukayo osetshenziswa ezimbonini ezihlukahlukene, okuhlanganisa upende, okokuhlanganisa, 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.
