Izitena ze-alumina zeBakala II eziphezulu (T-19)
IIMVELISO
Izitena eziPhezulu zeAlumina (T-19)
Inkcazo yezitena eziphezulu ze-alumina: (Iklasi I, II, III)
Ngokomxholo we-Al2O3, izitena eziphezulu ze-alumina zihlala zihlulwe zibe ngamabakala amathathu: iBakala I──Al2O3 umxholo>75%; Umxholo weBakala II──Al2O3 ngu-60~75%; Umxholo weBakala III──Al2O3 ngu-48~60%.
Amandla aphezulu acinezelayo, ubushushu bomthwalo ophezulu wokuthamba, i-anti peeling Izitena eziphakamileyo ze-alumina ze-alumina zenziwe nge-alumina ephezulu ye-bauxite njengeyona nto ingundoqo ekrwada ngokomeleza ukudibanisa okusondeleyo kwe-matrix kunye namasuntswana, ukongeza i-binder edibeneyo, kunye ne-sintering kwiqondo lokushisa eliphezulu. Uneempawu zokumelana noxinzelelo oluphezulu, ubushushu obuthambileyo bomthwalo ophezulu, i-anti peeling, njl njl. Ifanelekile kakhulu kwi-lining ye-boilers ye-CFB kunye nezinye ii-kilns ezishisayo.
Uzinzo oluhle lomthamo kwiqondo lokushisa eliphezulu. Amandla omatshini aphezulu. Ukumelana nokunxiba kakuhle. Ithishu ixinene. I-porosity ephantsi. Ukuchasana kakuhle kwe-slag. Umxholo we-iron oxide uphantsi.
Ngokukodwa ibandakanya izitena eziphezulu ze-alumina, izitena zodongwe, izitena ze-corundum, izitena ze-silicon carbide kunye nezitena zekhabhoni. Kwisithando somlilo, ngenxa yeemeko zokusebenza ezahlukeneyo zecandelo ngalinye, ukuguquguquka kweqondo lokushisa kukhulu, kwaye ukutshitshiswa kwe-thermal kuthathwe yinxalenye nganye kukwahluke, ngoko ke i-refractory efunekayo yinxalenye nganye ikwahluke.
