Kgatisong ena re tla tswela pele ho hlahisa thepa ya ho kwahela difaeba tse thibelang ho thijwa e sebediswang kahong ya ontong
1) Faeba e halefisang
Faeba e hanelang, e tsejoang hape e le faeba ea ceramic, ke mofuta oa thepa e sa etseng tšepe e entsoeng ke motho, e leng motsoako oa khalase kapa oa kristale oa binary o entsoeng ka Al2O3 le SiO2 e le likarolo tse ka sehloohong. Jwalo ka thepa e bobebe ea ho thibela e hanelang, e ka boloka matla ka 15-30% ha e sebelisoa liontong tsa indasteri. Faeba e hanelang e na le litšobotsi tse latelang tse ntle:
(1) Ho hanyetsa mocheso o phahameng. Mocheso o sebetsang oa faeba e tloaelehileng ea silicate e hanyetsang ea aluminium ke 1200°C, 'me mocheso o sebetsang oa faeba e khethehileng e hanyetsang joalo ka faeba ea alumina le mullite o phahame ho fihlela ho 1600-2000°C, ha mocheso o hanyetsang oa thepa ea fiber e akaretsang joalo ka asbestos le ulu ea lefika e ka ba 650°C feela.
(2) Ho thibela mocheso. Ho thibela mocheso ha faeba e hanyetsang ho tlase haholo mochesong o phahameng, mme ho thibela mocheso ha faeba e tloaelehileng e hanyetsang ya aluminium silicate ho 1000 °C ke 1/3 ea litene tse bobebe tsa letsopa, 'me matla a eona a mocheso a manyane, bokhoni ba ho thibela mocheso bo phahame. Botenya ba lesela le entsoeng ka ontong bo ka fokotsoa ka halofo ha bo bapisoa le tšebeliso ea litene tse thibelang mocheso tse bobebe.
Khatiso e latelang re tla tsoela pele ho e hlahisathepa ea ho thibela faeba e hanyetsange sebelisoa kahong ea sebōpi. Ka kopo lula u mametse!
