Lehlabathe la Ceramic
Sintered Ceramic Sand bakeng sa Foundry
• 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
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
