Lehlabathe la Ceramic le koahetsoeng ka Resin
Tlhaloso
Lehlabathe la ceramic le sebelisoa lehlabatheng la ho bōptjoa le lehlabathe la mantlha ho etsa hore hlobo ea khetla le mokokotlo oa likhetla li be le thepa ea ho hanyetsa mocheso o phahameng, katoloso e tlaase, ho putlama habonolo, le tlhahiso e tlaase ea khase, e ka thibelang ka katleho liphoso tsa ho atolosa ho li-castings. Bakeng sa li-cores tse nang le libopeho tse rarahaneng haholo, li ka sebetsana le bothata ba hore ho thunya lehlabathe ha ho bonolo ho kopana. Ke lehlabathe la ceramic le sebelisoang ts'ebetsong ea RCS.
Lehlabathe le feletseng la ceramic le sebelisetsoa ho etsa lehlabathe le koahetsoeng, 'me le sebelisoa khafetsa ka mor'a ho tsosolosoa, le ka ntlafatsang ka katleho boleng le katleho ea tlhahiso ea li-castings, ho fokotsa sekhahla sa li-castings scrape le litšenyehelo tsa tlhahiso ea likhoebo, litšenyehelo tsa nako e telele tsa tšebeliso li tlaase ho feta tseo. ea lehlabathe la silika. Ka hona, lilemong tsa morao tjena, hoo e ka bang limela tsohle tse kholo tsa lehlabathe tse koahetsoeng li sebelisitse lehlabathe la ceramic e le lehlabathe le tala ho hlahisa lehlabathe le koahetsoeng.
Likaroloana
• Refractoriness e phahameng—-ho lahlela litšepe tse nang le mocheso o phahameng oa mocheso (tšepe e entsoeng ka tšepe, tšepe e kopantsoeng, tšepe e sa hloekang, joalo-joalo)
• Matla a phahameng le ho tiea—–ho hlahisa li-cores tse rarahaneng tse nang le likarolo tse tšesaane.
• Katoloso e tlase ea mocheso—–ho qoba mathata a katoloso.
• Lihlahisoa tse phahameng tsa ho lokisoa—-ho fokotsa ho lahloa ha lehlabathe, ho theola litšenyehelo.
• Ho phalla hantle -–ho etsa li-cores tse rarahaneng.
• Tšebeliso e tlase ea li-binder--tlase ho fetoha ha khase, ho fokotsa litšenyehelo tsa tlhahiso.
• Litšobotsi tsa lik'hemik'hale tse sa sebetseng---e ka sebelisoa ho li-alloys leha e le life tse ratoang, tse kenyelletsang tšepe ea Manganese.
• Nako e telele ea polokelo.
