Tlhaloso

Seretse sa Refractory ke thepa e kopanetsoeng e sebelisetsoang ho haha lihlahisoa tse nang le sebōpeho sa sebopeho sa refractory. E entsoe ka phofo ea refractory, metsi kapa sekontiri se metsi le metsoako (e kang dispersant plasticizer, stabilizer kapa metsi a bolokang metsi). Seretse se kang sekontiri (kapa setenya) se nang le likaroloana tse thata tse ngata, tse nang le litšobotsi tsa mokelikeli oa Bingham. Boima bo tiileng / bo metsi bo ka ba (70 ~ 75) / (30 ~ 25) 'me tekanyo e tiileng / ea metsi e fapana ho ea ka matla a khoheli a phofo ea refractory, e ka bang (35 ~ 50) / (65 ~ 50). Hangata, e sebelisoa ka spatula.

Seretse se refractory, se tsejoang hape e le seretse sa mollo kapa thepa e kopaneng (phofo), e sebelisoang e le lisebelisoa tsa litene tsa bonding refractory, ho ea ka thepa e ka aroloa ka letsopa, aluminium e phahameng, silicon le seretse sa magnesium refractory, jj.

E bitsoa seretse se tloaelehileng sa refractory se entsoeng ka phofo ea refractory clinker le letsopa la polasetiki e le binder le moemeli oa 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, moea thatafatsa kapa thermo-hardening thepa e le binder, bitsoa lik'hemik'hale binding refractory seretse, e le ka tlaase ho sebopeho sa ceramic tlama mocheso pele ho tlhahiso ea itseng karabelo lik'hemik'hale le ho thatafala.

Likaroloana

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.

Kopo

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.
