Liphaepheng tsa tšepe tse entsoeng ka centrifugal tse entsoeng ka tšepe, lesela la corundum le na le ntlha e qhibilihisang ea likhato tse 2045. Ka lebaka la litšobotsi tse ikhethang tsa sebopeho tse bakoang ke mekhoa ea tlhahiso, likarolo tsa corundum le tsa tšepe li bonts'a likarolo tse fapaneng tsa khatello ea maikutlo. Ha e futhumala ho ea ho likhato tse 900 'me e qoelisoa khafetsa metsing a batang, pipe ea ceramic e boloka botšepehi ba eona ntle le ho phunyeha kapa ho arohana, ho bontša khanyetso e phahameng ea mocheso ha e bapisoa le lirafshoa tse tloaelehileng. Lera le ka hare le na le mofuta o teteaneng oa Aluminium oxide (Al₂O₃) o nang le tekanyo ea ho hanyetsa acid ea 96-98%. Joaloka oxide e sa nke lehlakore, aluminium oxide ha e sebetse ka lik'hemik'hale ka li-acids, alkalis, kapa letsoai.

1. Katleho ea ho Thibela Wear Resistance:
Matla a Ntlafetseng le Bophelo ba Tšebeletso
The core layer e sebelisa corundum ceramic (Al₂O₃) ka bohloeki E kholo ho feta kapa e lekanang le 95%, ho finyella boima ba Mohs ba 9.0 (e lekanang le HRC E kholo ho feta kapa e lekanang le 90). Sesebediswa sena se bontsha ka makgetlo a fetang 10 ho hanyetsa ha tshepe e timang le ho feta ha hlano ho feta-chromium cast iron.
Melemo e Sebetsang
Likopong tsa ts'ebetso ea liminerale, bophelo ba ts'ebeletso bo atolosoa ka makhetlo a fetang a mahlano ha ho ntse ho fokotsa litšenyehelo tsa selemo le selemo tsa tlhokomelo ka 60% -68%.

2. Likarolo tsa Ntlafatso ea ho Boloka Matla le Ntlafatso ea Matla
Ntlafatso ea ho hanyetsa metsi ka har'a marako a ka hare ho Ra Less kapa a lekana le 0.8μm (haufi le seipone sa seipone) Ho hlakile hore coefficient ea ho hanyetsa metsi ke 0.0193 feela, e ka tlaase ho feta ea pipe ea tšepe e se nang seamless, e fokotsa tšebeliso ea matla ka 15% -20%.
Moqapi o bobebe
Boima ba 50% bo bobebe ho feta peipi ea lejoe la setso, e fokotsa litšenyehelo tsa morero ka 20% -40%.
3. Khanyetso e Feteletseng ea Tikoloho
