• Moetso o tšoanang oa motsoako
• Kabo ea boholo ba lijo-thollo e tsitsitseng le ho kenella ha moea
• Refractoriness e phahameng (1825°C)
• Ho hanyetsa ho hoholo ho apara, ho senya le ho tsosoa ha mocheso
• Katoloso e nyane ea mocheso
• Mokelikeli o babatsehang le bokhoni ba ho tlatsa ka lebaka la ho ba chitja
• Sekhahla se phahameng ka ho fetisisa sa tokiso tsamaisong ea loop ea lehlabathe

Foundry Ceramic Sand - tharollo e phethahetseng bakeng sa litlhoko tsohle tsa hau tsa motheo. Sehlahisoa sena sa boqapi se boetse se tsejoa e le ceramsite, cerabeads, kapa ceramcast, 'me se entsoe ka bauxite ea calcined e e fang sebopeho se setle sa koro. Ka lintho tse phahameng tsa aluminium oxide le silicon oxide, Lehlabathe la Ceramic le ithorisa ka thepa e phahameng ha e bapisoa le lehlabathe le tloaelehileng la silika.
Ceramic Sand e fana ka melemo e mengata ho feta lehlabathe la silika. Taba ea pele, e na le refractoriness e phahameng haholo, e etsang hore e be e loketseng ho sebelisoa lits'ebetsong tsa mocheso o phahameng. E boetse e na le katoloso e tlase ea mocheso, ho netefatsa hore e boloka hlobo ea lehlabathe kapa sebopeho sa mantlha le ho tsitsisa le nakong ea mocheso o feteletseng.
Ntle le matla a eona a tsotehang, Lehlabathe la Ceramic le fana ka phallo e babatsehang - sena se tiisa hore se ka bōptjoa habonolo le ho bōptjoa nakong ea ho lahla. Ho feta moo, Lehlabathe la Ceramic le na le khanyetso e phahameng ea ho roala, ho silakanya le ho sisinyeha ha mocheso, e leng se etsang hore e be khetho e nepahetseng bakeng sa mefuta eohle ea lisebelisoa tsa ho lahlela.
Molemo o mong oa bohlokoa oa ho sebelisa Lehlabathe la Ceramic la Foundry ke hore le na le sekhahla se phahameng sa ho khutlisa, ho bolelang hore se ka sebelisoa habonolo ts'ebetsong ea ho lahla. Sena, le sona se thusa ho fokotsa litšila le ho fokotsa litšenyehelo.
Ka kakaretso, Foundry Ceramic Sand ke ntho eo u lokelang ho ba le eona bakeng sa setsi leha e le sefe se batlang ho ntlafatsa ts'ebetso ea bona ea ho lahla. Ka thepa ea eona e ntle haholo le matla a holimo, e fana ka monyetla o moholo ho feta lehlabathe la silika la setso.
