I-kaolin egayiwe kanye ne-kaolin egeziwe inomehluko olandelayo:
1, Imvelo yenhlabathi yokuqala ihlukile. I-kaolin ebaliwe ibalwa, uhlobo lwekristalu kanye nezakhiwo zenhlabathi yokuqala zishintshiwe.
Kodwa-ke, ukugeza i-kaolin kuwukwelapha ngokomzimba kuphela, okungeke kuguqule izakhiwo zenhlabathi yokuqala.
2, Ubumhlophe buhlukile. Ubumhlophe buzokhula ngemva kokudubula kwentuthu ye-kaolin ene-calcined. Ukugeza amanzi nge-kaolin akuzange kukhule kakhulu
Engeza ubumhlophe.
3, Isicelo sihlukile. I-kaolin ene-calcined ivame ukusetshenziswa njengesengezo sokwenza iphepha kanye nokuhlanganisa okuphikisayo. Futhi wageza kaolin eyodwa
Ngokuvamile isetshenziswa njenge-papermaking filler.
4, Izindleko zihlukile. Izindleko ze-kaolin e-calcined ziphezulu, kuyilapho izindleko ze-kaolin ewashiwe ziphansi.
5, Ukunamathela kwenhlabathi kwangempela kuhlukile. I-kaolin Calcined, inhlabathi yokuqala ayibumbene, ayikwazi ukusetshenziswa ngokuqondile njengempahla eluhlaza yokwenza iphepha noma izinto eziphikisayo, zidinga ukubalwa emva kokusebenza. Inhlabathi yokuqala ye-kaolin egeziwe inempahla yokunamathisela futhi ingasetshenziswa ngokuqondile njenge-refractory binder noma isigcwalisi sokwenza iphepha.
