Ubukhulu bezinhlayiyana buncane, buphezulu ubumhlophe.Lapho ubukhulu bezinhlayiya buba mahholo, kuba nzima nakakhulu ukususa ikhabhoni, ikakhulukazi ikhabhoni engaphakathi kwezinhlayiyana akulula ukuvungama, okuthinta ubumhlophe bomkhiqizo owenziwe nge-calcined.Impahla eluhlaza ilungile, indawo engaphezulu inkulu, ikhabhoni kulula ukuyisusa, ikhabhoni kulula ukuyishintsha, kanti ubumhlophe bomkhiqizo obaliwe buphezulu.

Enqubweni yokubala ubumhlophe bomkhiqizo, i-kaolin inomkhuba wokunensa kanye nokwenyuka kwezinga lokushisa lokubala.Uma kuqhathaniswa ne-900 ℃, 850 ℃ calcination kaolin, imikhiqizo ye-kaolin ayisusi amanzi ekristalu kuphela, yandisa usayizi we-pore, kodwa futhi igcina i-flaky, imhlophe ephezulu, ehambisana nokushisa kwe-calcination, inciphisa izindleko zokutshala izimali nokungcoliswa kwemvelo, ngakho-ke i-850 ℃ iyizinga lokushisa elingcono kakhulu lokubala.

Ubumhlophe bomkhiqizo buyanda ngesikhathi sokushisa esingashintshi, kodwa ukuthambekela kuhamba kancane.Uma izinga lokushisa lilifushane kakhulu, akulula ukukhipha ikhabhoni eku-kaolin.Ngemuva kwamahora angaphezu kwama-4 okushisa okungaguquki, izinga lokuqothula nokuphelelwa amandla kwamanzi komkhiqizo lincane, ngakho-ke ubumhlophe bomkhiqizo buyathuthukiswa, kodwa ukuthuthukiswa kuncane kakhulu.Ukuze kuthuthukiswe ukusebenza kahle kokushisa, ukulawulwa kwezinga lokushisa okungaguquki komkhiqizo we-calcined kulungele amahora angu-4

Ngokusebenzisa izithasiselo ezihlukene zokubala, inqubo yokukhiqiza yenziwa lula, izindleko ziyancipha, futhi ubumhlophe bemikhiqizo ye-calcined buthuthukiswa kakhulu.Phakathi kwabo, i-sodium chloride iyisengezo esiphumelela kakhulu.Ukwethulwa kwe-urea njenge-ejenti yokuhlanganisa futhi kwandisa ubumhlophe be-kaolin e-calcined

Ukulawulwa komkhathi wokubala kunethonya elikhulu kumhlophe kanye nokuphuzi kwemikhiqizo e-calcined.Ukuze kuhlangatshezwane nezidingo zokukhishwa kwekhabhoni yochungechunge lwamalahle e-kaolin, ukubalwa emkhathini we-oxidizing kubangela i-iron oxide ephansi kanye nenani eliphezulu, okuzoholela nakanjani ekwenyukeni kokukhishwa kwekhabhoni kanye nokubaphuzi kwemikhiqizo ye-kaolin.Ngakho-ke, ukubala ku-850 ℃ ekushiseni okuphezulu nokunciphisa umoya kunganciphisa insimbi ephansi nensimbi ephezulu, ukulawula umoya wokubala, ukunciphisa ubumhlophe futhi kuthuthukise ukuphuzi kwemikhiqizo.
