Phaephe ea ceramic ea Silicon Carbide e sa Khaotseng ho Apara
Sesepa sa silicon carbide: Bothata ba Moh ke 9.0~9.2, bo na le khanyetso e ntle khahlanong le khoholeho le mafome, bo hanyetsa ho kgohlopa le ho thibela oxidation ka makgetlo a 4 ho isa ho a 5. Bolelele ba tshebeletso bo feta thepa ya alumina ka makgetlo a 7 ho isa ho a 10. MOR ya RBSiC e feta ya SNBSC ka makgetlo a 5 ho isa ho a 7, e ka sebediswa bakeng sa dibopeho tse rarahaneng haholoanyane.
Ho hanyetsa ho roala ha silicon carbide, e entsoe ka silicon carbide le carbon mochesong o phahameng, ke ea mofuta oa sehlahisoa sa silicon carbide. Likarolo tsa ho hanyetsa ho roala ha silicon carbide li sebelisoa haholo merafong, ho sila lirafshoa, ho hlahloba le ho tsamaisa ho roala ho phahameng, maro a mangata a senyang, hape li loketse haholo lihlahisoa tsa mechini tse nang le litlhoko tse nepahetseng le tsa ho tiisa, joalo ka pompo ea khatello e phahameng, pompo ea makenete jj. Ke mofuta o mocha oa thepa ea ho hanyetsa ho roala. Sekontiri sa ho hanyetsa ho roala sa silicon carbide se kopantsoeng le karabelo se na le litšobotsi tsa ho thatafala ho hoholo, ho hanyetsa ho roala ho phahameng, ho hanyetsa tšusumetso, ho hanyetsa mocheso o phahameng, ho hanyetsa asiti le alkali joalo-joalo, 'me bophelo ba sebele ba tšebeletso bo feta makhetlo a 6 ho feta polyurethane. E loketse haholo ts'ebetso ea ho arola, ho tsepamisa maikutlo le ho felloa ke metsi ha thepa e matla e khorofo le e nang le mahoashe, e sebelisitsoe ka katleho merafong e mengata. Khamphani ea rona ke mofani oa lihlahisoa tsa ceramic tsa silicon carbide ea litsebi, ho thatafala ho latela daemane feela, ho hanyetsa ho roala ho phahameng, litšobotsi tsa bophelo bo bolelele ba tšebeletso. Phaephe ea ho hanyetsa ho roala le setsoe e hlahisitsoeng ka lesela la ho hanyetsa ho roala la silicon carbide, botenya ba lona ba ceramic ke 6-35mm, sebopeho ke sa ho kenya se seng se ntse se le teng. Tube ea letsopa e sintered ka har'a tube ea tšepe ea caliber e tsamaellanang, 'me sekhomaretsi se bohareng. Liphaephe tsa letsopa tse hanyetsang ho roala li na le litšobotsi tse latelang ha li bapisoa le liphaephe tsa majoe a cast-stone tse neng li sebelisitsoe pele, liphaephe tsa tšepe tse kopantsoeng tse sa tsofaleng le liphaephe tse kopaneng tsa ceramic.
Carbide ea silicon e kopantsoeng le karabelo (RBSC) e na le ts'ebetso e ntle e hanelang ho tsofala, e na le litšobotsi tse ntle mochesong o phahameng, khoholeho e ntle le khanyetso e matla, litšobotsi tsena li ka sebelisoa lits'ebetsong tse fapaneng tse kang liphaephe, setsoe sa ceramic, li-nozzle tsa spray, li-nozzle tsa shot blast le likarolo tsa hydrocyclone.
Li-lining tsa ZPC li tšoarella ho feta li-liner tse nang le lithaele le tsa tšepe. Li-ceramic tsa ZPC silicon carbide lia hanyetsa mocheso le ho halefa, e leng se fellang ka linako tse telele tsa ho sebetsa le ho fokotseha ha nako ea ho sebetsa.
Sesepa sa silicon carbide se kopantsoeng le karabelo (RBSIC) ke thepa e loketseng e hanelang ho tsofala, e loketseng haholo bakeng sa ho khohlela ho matla, likaroloana tse mahoashe, ho hlophisoa, mahloriso, ho felloa ke metsi le mesebetsi e meng. Ka lebaka la thepa e ka holimo,Sekotjana sa silicon carbide sa RBSiC / SiSiCe ka sireletsa karolo ka katleho ho tsofala le mocheso o phahameng e le ho lelefatsa bophelo ba ts'ebeletso ea lisebelisoa.
