Tlhahisoleseding ya Sehlahiswa
Seretse se refractory,hape e tsejoa e le seretse sa mollo kapa thepa e kopaneng (phofo), e sebelisoang e le lihlahisoa tsa bonding refractory brickwork thepa, ho ea ka thepa e ka aroloa kaletsopa, aluminium e phahameng, silicon le seretse sa magnesium refractory, joalo-joalo.
E bitsoaseretse se tloaelehileng sa refractorye entsoeng ka phofo ea refractory clinker le letsopa la polasetiki e le setlamo le sekheo sa polasetiki. Matla a eona ka mocheso oa kamore a tlaase, 'me ho thehoa ha ceramic bonding ka mocheso o phahameng ho na le matla a phahameng. Ka hydraulicity, ho thatafatsa moea kapa thepa ea thermo-hardening e le binder, e bitsoangkhemikhale e tlamang seretse se refractory, joalo ka ka tlase ho sebopeho sa mocheso o tlamang oa ceramic pele ho hlahisoa karabelo e itseng ea lik'hemik'hale le ho thatafala.
Litšobotsi tsa seretse sa Refractory:polasetiki e ntle, kaho e bonolo; matla a phahameng a tlamahano, khanyetso e matla ea kutu; refractoriness phahameng, ho fihlela ho 1650 ℃ ± 50 ℃; khanyetso e ntle ea tlhaselo ea slag; thepa e ntle ea mocheso oa mocheso.
Seretse sa refractory se sebelisoa haholo ka ontong ea coke, sebōpi sa khalase, sebōpi sa mollo, setofo se chesang se chesang, metallurgy, indasteri ea thepa ea meralo, mechine, petrochemical, khalase, boiler, matla a motlakase, tšepe le tšepe, samente le lisebelisoa tse ling tsa indasteri.
