Uma usayizi wezinhlayiya uncane, kulapho ubumhlophe buphakama khona. Uma usayizi wezinhlayiya ukhulu kakhulu, kulapho kunzima kakhulu ukususa ikhabhoni, ikakhulukazi ikhabhoni engaphakathi kwezinhlayiya akulula ukuyishintsha ibe yizivuthu, okuthinta ubumhlophe bomkhiqizo one-calcium. Izinto zokusetshenziswa zilungile, indawo engaphezulu inkulu, ikhabhoni kulula ukuyisusa, ikhabhoni kulula ukuyishintsha ibe yizivuthu, kanti ubumhlophe bomkhiqizo one-calcium buphakeme.

Enkambisweni yokukhiqiza ubumhlophe bomkhiqizo, i-kaolin inesimo sokuhamba kancane ngokukhuphuka kwezinga lokushisa le-calcination. Uma kuqhathaniswa ne-900 ℃, i-calcination ye-kaolin engu-850 ℃, imikhiqizo ye-kaolin ayisusi nje kuphela amanzi ekristalu, yandisa usayizi we-pore, kodwa futhi igcina ubumhlophe obuqhekekile, obuhambisana nokushisa kwe-calcination, inciphisa izindleko zokutshalwa kwezimali kanye nokungcola kwemvelo, ngakho-ke i-850 ℃ iyizinga lokushisa elihle kakhulu le-calcination.

Ubumhlophe bomkhiqizo buyanda ngesikhathi sokushisa esingaguquki, kodwa umkhuba uhamba kancane. Uma izinga lokushisa lifushane kakhulu, ikhabhoni ku-kaolin akulula ukuyisusa. Ngemva kwamahora angaphezu kwama-4 okushisa okungaguquki, izinga lokukhishwa kwekhabhoni kanye nokuphelelwa amanzi emzimbeni komkhiqizo lincane, ngakho-ke ubumhlophe bomkhiqizo buyathuthuka, kodwa ukuthuthuka kuncane kakhulu. Ukuze kuthuthukiswe ukusebenza kahle kokushisa, ukulawulwa kokushisa okungaguquki komkhiqizo one-calcium calcium kufaneleka kakhulu amahora ama-4.

Ngokusebenzisa izithasiselo ezahlukene ze-calcining, inqubo yokukhiqiza yenziwa lula, izindleko ziyancishiswa, futhi ubumhlophe bemikhiqizo ene-calcined buthuthukiswa kakhulu. Phakathi kwazo, i-sodium chloride iyisithasiselo esisebenza kahle kakhulu. Ukwethulwa kwe-urea njenge-intercalation agent kwandisa nobumhlophe be-kaolin ene-calcined

Ukulawulwa kwesimo sezulu se-calcination kunethonya elikhulu ebumhlopheni nasekuphuzini kwemikhiqizo ene-calcium. Ukuze kuhlangatshezwane nezidingo zokususwa kwekhabhoni kwe-kaolin yochungechunge lwamalahle, i-calcination emoyeni oxidizing iholela ku-oxide yensimbi ephansi kanye nentengo ephezulu, okuzoholela ekwandeni kokususwa kwekhabhoni kanye nokuphuzi kwemikhiqizo ye-kaolin. Ngakho-ke, i-calcination ku-850 ℃ ekushiseni okuphezulu kanye nomoya ophansi kunganciphisa insimbi ephansi kanye nensimbi ephezulu, kulawule umoya we-calcination, kunciphise ubumhlophe futhi kuthuthukise ukuphuzi kwemikhiqizo.
