Lehlabathe la Ceramsite
Lehlabathe la Ceramic le Fuselitsoeng bakeng sa Foundry
• Moetso o tšoanang oa motsoako
• Kabo ea boholo ba lijo-thollo e tsitsitseng le ho kenella ha moea
• Refractoriness e phahameng (1800°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
RCS (lehlabathe le koahetsoeng ka resin)
Mokhoa o batang oa lehlabathe la lebokose
Ts'ebetso ea lehlabathe ea khatiso ea 3D (Kenyelletsa resin ea Furan le PDB Phenolic resin)
Ts'ebetso ea lehlabathe la resin e sa bake (kenyelletsa resin ea Furan le Alkali phenolic resin)
Ts'ebetso ea ho tsetela/ Ho lahleheloa ke boka ba linotsi

Fused Ceramic Sand ke sephetho sa boitelo ba rona ba ho theha litharollo tsa boleng bo holimo bakeng sa litlhoko tsa hau tsa ho lahlela. Lehlabathe la ceramic le kopantsoeng ke lehlabathe le khethehileng la ceramic le entsoeng ka mokhoa oa electrofusion granulation. Mokhoa ona o tiisa hore lehlabathe ke la boleng bo phahameng ka ho fetisisa, le nang le bokaholimo bo boreleli le litlhaloso tse ntle tsa ts'ebetso.
Likarolo tsa mantlha tsa lehlabathe la rona la ceramic le kopantsoeng ke alumina le silika. Mehaho e ikhethang ea lehlabathe la rona le kopantsoeng la ceramic e etsa hore e be khetho e ntle bakeng sa ts'ebetso ea hau ea ho theha. Ho hanyetsa ho phahameng ha lehlabathe ho etsa hore e be e loketseng ho sebelisoa lits'ebetsong tsa mocheso o phahameng, 'me phallo ea eona e babatsehang e tiisa hore e ka tlatsa hlobo kapele le ka katleho. Ho feta moo, ho hanyetsa ho hoholo ha lehlabathe ho abrasion, compression le ho tsukutloa ha mocheso ho bolela hore e tšoarella haholo, e fokotsa litšila le ho lelefatsa bophelo ba hlobo.
Khamphaning ea rona, re motlotlo ka ho lula re hlahisa lihlahisoa tsa boleng bo holimo. Lehlabathe la rona le kopantsoeng la ceramic ha ho joalo! Ka lehlabathe la rona, o ka kholiseha hore o fumana sehlahisoa sa boleng bakeng sa litlhoko tsohle tsa hau tsa ho lahlela.
