Setene sa silicon carbide
Setene sa silicon carbide
1. Litaba tsa mantlha tsa setene sa silicon carbide ke SiC, litaba ke 72% -99%. Litene tsa silicon carbide li sebelisoa liindastering tse fapaneng le thepa ea mocheso ka lebaka la likarolo tse fapaneng. Ho latela mekhoa e fapaneng ea ho kopanya, baetsi ba litene tsa silicon carbide ba arotsoe ka ho kopanya letsopa, Sialon bonding, alumina bonding, self bonding, high aluminium bonding, silicon nitride bonding, joalo-joalo. Mesebetsi ea litene tsa silicon carbide ke efe? Likopo tsa mantlha ke li fe?
2. Hobane thepa e tala ea setene sa silicon carbide ke silicon carbide, silicon carbide, e tsejoang hape e le emery, e entsoe ka ho qhibiliha ha mocheso o phahameng oa thepa e tala joalo ka lehlabathe la quartz, coke le mapolanka. Silicon carbide e sebelisoa khafetsa ho etsa li-Refractories tse tsoetseng pele ka lebaka la lik’hemik’hale tse tsitsitseng tsa lik’hemik’hale, mafura a phahameng a futhumatsang mocheso, coefficient e tlase ea ho holisa mocheso le khatello e ntle ea ho roala.
3. Litene tsa silicon carbide li sebetsoa ka mochini o chesang mocheso oa mocheso o sebelisang litšobotsi tsa silicon carbide joalo ka ts’enyeho ea ts’enyeho, mocheso o phahameng oa matla, matla a phahameng, khatello e ntle ea mocheso le khanyetso ea tšusumetso, ‘me e sebelisoa maemong a fapaneng a phahameng thepa ea mocheso.
4. Lihlahisoa tsa silicon carbide li sebelisa silicon carbide e le lihlahisoa tse tala, eketsa letsopa, silicon oxide le li-binders tse ling ho sinter ka 1350 ho 1400 ° C. Silicon carbide le phofo ea silicon le tsona li ka etsoa lihlahisoa tsa silicon nitride-silicon carbide sebakeng sa naetrojene seboping sa motlakase. Lihlahisoa tsa k’habone li na le coefficient e tlase haholo ea ho holisa mocheso, ho futhumatsa ho phahameng ha mocheso, ho tsitsipana ho matla ha mocheso le matla a phahameng a mocheso. Ha e nolofatse kamora tšebeliso ea nako e telele mocheso o phahameng, ha e silafatsoe ke asiti le alkali efe kapa efe, e na le letsoai le matla la ho hanyetsa, ebile ha e kolobisoe ke tšepe le slag. Boima bo bobebe ebile ke sesebelisoa sa boleng bo holimo se nang le mocheso o phahameng. The bozangi litomba ke hore ho ke ke ho le bonolo ho oxidize ka thempereichara e phahameng ‘me ha a loketse ho sebelisoa ka sepakapakeng oxidizing. Lihlahisoa tsa k’habone li sebelisoa haholo ka har’a li-linings tse nang le mocheso o phahameng oa mocheso (botlaaseng ba sebōpi, leifo, karolo e ka tlase ea mochini oa sebōpi, jj.), Hape le lera la lisebelisoa tse se nang tšepe tsa tšepe.
5. Liqholotso tse amanang le ‘mele le lik’hemik’hale tsa litene tsa silicon carbide:
