Tlhaloso:
Silicon carbide phofo:
β-SiC phofo e na le botsitso bo phahameng ba lik'hemik'hale, boima bo phahameng, conductivity e phahameng ea mocheso, coefficient e tlase ea ho atolosa mocheso, lekhalo le leholo la matla a motlakase, lebelo le phahameng la elektronike, ho tsamaea ha elektronike, litšobotsi tse khethehileng tsa mocheso, joalo-joalo, kahoo e na le anti-wear. Ho hanyetsa mocheso o phahameng, ho hanyetsa mocheso, ho hanyetsa kutu, ho hanyetsa mahlaseli, thepa e ntle ea semi-conductive le thepa e meng e babatsehang, e sebelisoa haholo ho lisebelisoa tsa elektroniki, tlhahisoleseding, theknoloji ea ho sebetsa ka mokhoa o nepahetseng, sesole, sefofane, lisebelisoa tse tsoetseng pele tsa refractory, lisebelisoa tse khethehileng tsa ceramic, ho sila ho tsoetseng pele. Lisebelisoa le lisebelisoa tsa ho matlafatsa le masimo a mang.Sebaka sa ts'ebeliso ea eona se arotsoe haholo ka mekhahlelo e latelang:
Kopo e ka sehloohongea SiC powders:
1. Sintered phofo
β-SiC e na le tebello e pharaletseng ea ts'ebeliso 'marakeng oa lirafshoa tse tsoetseng pele tsa meralo, lirafshoa tse sebetsang le lisebelisoa tse tsoetseng pele tsa refractory.Ho kenyelletsa β-SiC ho lihlahisoa tsa ceramic tsa boron carbide ho ka ntlafatsa ho tiea ha sehlahisoa ha ho ntse ho fokotsa mocheso oa sintering, ka tsela eo ho ntlafatsa haholo ts'ebetso ea boron carbide ceramics.
2. Lisebelisoa tsa elektronike
E le thepa ea semiconducting, β-SiC e phahame ka makhetlo a 'maloa ho feta α-Sic.Phello ea anti-corona ea jenereithara ka mor'a ho eketsa β-SiC e hlakile haholo, hape e na le ho hanyetsa ho apara hantle le ho hanyetsa mocheso o phahameng.Lisebelisoa tsa liphutheloana tsa elektronike, li-heaters, li-heaters tsa mocheso, joalo-joalo tse entsoeng ka β-SiC li na le khanyetso e phahameng ea mocheso oa mocheso, conductivity e ntle ea mocheso, le ts'ebetso ea lihlahisoa e molemo haholo ho feta lisebelisoa tse ling.
3. Ho roala ho khethehileng
Hobane β-SiC e na le sebopeho sa daemane, likaroloana li pota-potile, li na le khanyetso e kholo ea ho roala, ho hanyetsa kutu, conductivity e phahameng ea mocheso, coefficient e tlaase ea ho atolosa, joalo-joalo, kahoo e na le ts'ebetso e ntle ka liphahlo tse khethehileng.
4. Lisebelisoa tsa ho sila le ho bentša
E le lisebelisoa tse nepahetseng tsa ho sila le ho bentša, β-SiC e na le ts'ebetso e phahameng haholo ea ho sila ho feta white corundum le α-SiC, 'me e ka ntlafatsa haholo qetello ea sehlahisoa.
Β-SiC seretse se silang, mokelikeli o silang, lebanta la lesela la emery le nepahetseng haholo le lesela le sa senyeheng haholo le tsona li na le menyetla e metle ea ts'ebeliso.
5. Li-additives tse khethehileng tsa boemo bo phahameng
Ho eketsoa ha β-Sic ho lisebelisoa tse entsoeng ka polymer le lisebelisoa tsa tšepe li ka ntlafatsa haholo ts'ebetso ea tsona ea mocheso, ho fokotsa coefficient ea ho atolosa, ho eketsa khanyetso ea ho apara, joalo-joalo, 'me hobane matla a itseng a β-SiC a nyenyane, ha a ame boima ba sebopeho. tsa thepa.Ts'ebetso ea lisebelisoa tsa nylon tse matla haholo, li-plastiki tse khethehileng tsa boenjiniere polyether ether ketone (PEEK), lithaere tsa rabara, le oli ea lubricating e thibelang khatello e kenngoa ho phofo ea ultrafine β-SiC, 'me ts'ebetso ea eona e totobetse haholo.
6. Lisebelisoa tse ling.
Boemo ba polokelo:
Beta silicon carbide powder / cubic SiC powder e lokela ho bolokoa sebakeng se omileng, se pholileng le se tiisitsoeng sa tikoloho, e ke ke ea pepeseha moeeng, e boloke sebakeng se lefifi.ho phaella moo e lokela ho qoba khatello e boima, ho ea ka lipalangoang tse tloaelehileng tsa thepa.
