Ubuncinci ubungakanani bamasuntswana, buphezulu ubumhlophe.I-coarser ye-particle size, kunzima kakhulu ukususa i-carbon, ngakumbi i-carbon ngaphakathi kwi-particle akulula ukuyi-volatilize, echaphazela ubumhlophe bemveliso ye-calcined.Izinto ezikrwada zilungile, indawo engaphezulu inkulu, ikhabhoni kulula ukuyisusa, i-carbon ilula ukuguquguquka, kwaye ubumhlophe bemveliso ye-calcined buphezulu.

Kwinkqubo yokubala ubumhlophe bemveliso, i-kaolin inomkhuba ocothayo kunye nokwanda kobushushu becalcination.Xa kuthelekiswa ne-900 ℃, i-850 ℃ i-kaolin calcination, iimveliso ze-kaolin azisusi nje amanzi ekristale, ukwandisa ubungakanani be-pore, kodwa zigcina i-flaky, i-whiteness ephezulu, ye-calcination yokushisa, ukunciphisa iindleko zotyalo-mali kunye nongcoliseko lokusingqongileyo, ngoko i-850 ℃ lolona bushushu bokubala bungcono.

Ubumhlophe bemveliso buyanda ngexesha lobushushu obuqhubekayo, kodwa umkhwa uyacotha.Xa ubushushu bufutshane kakhulu, akukho lula ukususa ikhabhoni kwi-kaolin.Emva kweeyure ezingaphezu kwe-4 zokushisa okungapheliyo, iqondo le-decarburization kunye nokuchithwa kwamanzi kwimveliso kuncinci, ngoko ubumhlophe bemveliso buphuculwe, kodwa ukuphuculwa kuncinci kakhulu.Ukuze kuphuculwe ukusebenza kakuhle kwe-thermal, ukulawulwa kweqondo lokushisa rhoqo kwimveliso ye-calcined ifaneleka ngakumbi kwiiyure ze-4

Ngokusebenzisa izongezo ze-calcining ezahlukeneyo, inkqubo yokuvelisa ilula, ixabiso liyancitshiswa, kwaye ubumhlophe beemveliso ze-calcined ziphuculwe kakhulu.Phakathi kwabo, i-sodium chloride iyona yongezelela isebenzayo.Ukuqaliswa kwe-urea njenge-arhente yokudibanisa kwakhona kwandisa ubumhlophe be-kaolin ene-calcined

Ukulawula umoya we-calcination kunempembelelo enkulu kumhlophe kunye nokuphuzi kweemveliso ze-calcined.Ukuhlangabezana neemfuno zokususwa kwekhabhoni ye-kaolin yamalahle, ukubala kwi-oxidizing umoya kuphumela kwi-iron oxide ephantsi kunye nexabiso eliphezulu, nto leyo eya kukhokelela ngokuqinisekileyo ekwandeni kokususwa kwekhabhoni kunye nokutyheli kweemveliso ze-kaolin.Ke ngoko, ukubala kwi-850 ℃ kubushushu obuphezulu kunye nokunciphisa umoya kunokunciphisa intsimbi ephantsi kunye nentsimbi ephezulu, ukulawula umoya wokubala, ukunciphisa ubumhlophe kunye nokuphucula ukutyheli kweemveliso.
