Roller ea Carbide ea Silicon
Lirolara tsa Silicon Carbide (SiC)ke likarolo tsa mantlha tsa phetiso ea li-roller kiln, tse sebelisoang haholo ho beseng li-ceramic tsa meralo, lisebelisoa tsa bohloeki, li-ceramic tsa lapeng le li-ceramic tsa elektroniki. Ho latela ts'ebetso ea tlhahiso, li arotsoe ka mefuta e 'meli: Reaction Bonded Silicon Carbide (RBSiC) le Recrystallized Silicon Carbide (RSiC).
Papiso ea Mofuta:
1. Reaction Bonded SiC (RBSiC):
Sebopeho: E na le palo e nyane ea silicon e lokolohileng.
Melemo: E teteaneng haholo, e matla haholo, ebile e theko e tlase.
Mocheso o Phahameng: Ho fihlela ho 1400°C.
Tšebeliso: E loketse li-roller kiln tsa mocheso o mahareng ho isa ho o phahameng tse besang lithaele le li-ceramic tsa lapeng. E fana ka tekanyo e ntle ka ho fetisisa ea ts'ebetso le theko.
2. SiC e Nchafalitsoeng (RSiC):
Sebopeho: Bohloeki bo phahameng hoo e batlang e se na mohato oa ho kopanya.
Melemo: Khanyetso e ikhethang ea mocheso o phahameng le khanyetso ea ho thekesela (ha ho na phetoho mochesong o phahameng).
Mocheso o Phahameng: Ho fihlela ho 1650°C+.
Tšebeliso: E loketse ho besoa ha thepa ea bohloeki ka mocheso o phahameng le li-ceramic tse khethehileng moo ho hlokahalang botsitso bo feteletseng ba mocheso.
Likarolo tsa Bohlokoa:
1. Matla a Phahameng a Mocheso o Phahameng:E boloka thepa e ntle ea mechini esita le mochesong o pakeng tsa 1400°C le 1600°C.
2. Khanyetso e Hlollang ea Thermal Shock:E hanela liphetoho tse potlakileng tsa mocheso, e thibela ho petsoha kapa ho robeha nakong ea potoloho ea ho futhumatsa le ho pholisa ka potlako.
3. Khanyetso e Phahameng ea ho Aparela:E eketsa nako ea tšebeletso le ho fokotsa litšenyehelo tsa tlhokomelo libakeng tsa ontong tse khorofo.
4. Khanyetso ea ho Sila le ho Oxidation:E sebetsa hantle maemong a fapaneng a ontong, e hanela khoholeho ea lik'hemik'hale.
5. Ho nepahala ha Tekanyo e Phahameng:Qetello e boreleli e netefatsa hore lihlahisoa tsa letsopa li tsamaisoa ka mokhoa o tsitsitseng le o nepahetseng.
