Phaephe e sireletsang ea silicon carbide

Liindastering moo maemo a feteletseng a sokelang botšepehi ba lisebelisoa,liphaephe tse sireletsang tsa silicon carbide (SiC)E hlaha e le tharollo e ncha. Ho fapana le thepa e tloaelehileng ea tšireletso, li-tube tsa SiC li kopanya saense e tsoetseng pele ea thepa le boenjiniere bo matla ho sireletsa lisebelisoa le lits'ebetso tsa bohlokoa. E na le melemo e latelang:

1. Tšireletso e sa Bapisoeng Maemong a Bohanyetsi

Li-tube tse sireletsang tsa SiC li sebetsa e le mola oa pele oa tšireletso libakeng tseo ho hloleha e seng khetho:

（1）Tšireletso ea Thermal: E mamella mocheso o tsitsitseng ho fihlela ho 1600°C, li-sensor tse sireletsang, li-thermocouple, kapa li-probe tse tsoang litšepeng tse qhibilihisitsoeng, malakabe le plasma.

（2）Ho Sireletsa Likotsi Tsa Lik'hemik'hale: Ho Hanela ho bola ho bakoang ke li-acid (mohlala, sulfuric, hydrochloric), alkali, le likhase tse arabelang joalo ka chlorine kapa li-sulfur oxides.

Ho Hanela ho Hlweka ha Mahlasedi: Sireletsa kgahlanong le dikarolwana tse hoholehang dibetheng tse nang le mokelikeli, di-gasifier tsa mashala, kapa mesebetsing ya merafo.

2. Ho nepahala le botsitso bakeng sa litekanyo tsa bohlokoa

Lits'ebetsong tsa indasteri tse nang le likotsi tse kholo, ho nepahala ke habohlokoa ka ho fetisisa. Li-tube tsa SiC li ntlafatsa ts'epo ka:

（1）Ho Fokotsa Tšitiso ea Matšoao: Thepa e sa tsamaiseng motlakase e thibela tšitiso ea motlakase ho li-sensor tsa elektroniki.

（2）Botsitso ba Thermal: Ho fetoha ha thermal hoo e ka bang lefela ho netefatsa ho lekalekana ho tsitsitseng le ho nepahala ha tekanyo tlasa diphetoho tse potlakileng tsa mocheso.

（3）Botšepehi bo sa Keneng Khase: Sebopeho se sa keneng khase se thibela ho kenella ha khase, e leng sa bohlokoa bakeng sa litsamaiso tsa vacuum kapa sepakapaka se laoloang.

3. Ho nolofalletsa Theknoloji ea Moloko o Latelang Li-tube tse sireletsang tsa SiC ho notlolla boqapi masimong a ntseng a hlaha:

（1）Moruo oa Haedrojene: E sebetsa e le li-sheath tse tšoarellang bakeng sa li-sensor tlhahisong ea haedrojene, polokelong le liseleng tsa mafura, tse hanelang ho qhibiliha le ho pepesehela H₂ ka khatello e phahameng.

（2）Ho Hlahisa Semiconductor: Sireletsa di-sensor tsa optical le thermal ka hara di-reactor tsa CVD (Chemical Vapor Deposition) ho di-precursor tse senyang tse kang silane kapa ammonia.

（3）Ho Hlahloba Sebaka: Ho sireletsa disebediswa dienjeneng tsa rokete le di-probe tsa dipolanete ho tloha maemong a feteletseng a mocheso le mahlasedi a bokahohle.

4. Ho Boloka Litšenyehelo ka ho Phela Nako e Telele

Leha lipeipi tsa SiC li na le litšenyehelo tse holimo tsa pele, melemo ea potoloho ea bophelo ba tsona e hlalosa boleng bocha:

（1）Nako ea ho se sebetse e fokotsehile: Mekhoa e meng ea tšepe kapa ea quartz e ka tlosoang ka makhetlo a 4-6 maemong a khorofo kapa a asiti, e leng se fokotsang tlhokomelo e sa reroang.

（2）Litlhoko tsa ho Koahela ka Lefela: Ho fapana le litšepe tse hlokang ho koaheloa ka tšireletso, thepa ea tlhaho ea SiC e felisa litšenyehelo tse pheta-phetoang tsa kalafo ea bokaholimo.

（3）Ho sebelisoa hape: Ho pholoha lipotoloho tse ngata tsa ts'ebetso lits'ebetsong tse kang ho betla tšepe kapa ho theha khalase ntle le ho senyeha.

5. Ho iketsetsa bakeng sa Litlhoko tse Ikhethang

Li-tube tse sireletsang tsa SiC li ikamahanya le liphephetso tsa niche ka boenjiniere bo etselitsoeng motho ka mong:

（1）Meralo ea Motsoako: Kopanya le litšepe kapa liseramike bakeng sa likopano tse nang le mesebetsi e mengata (mohlala, lihokelo tse nang le khoele, li-flange).

（2）Liphetoho tsa Bokaholimo: Likamore tse bentšitsoeng bakeng sa lits'ebetso tsa mahlo kapa tsa kantle tse nang le sebopeho ho ntlafatsa ho qhala ha mocheso.

（3）Boholo ba ho tenyetseha: E entsoe ho tloha ho limilimithara (li-reactor tsa laboratori) ho isa ho limithara (li-kiln tsa indasteri).

6. Tokiso ea Botsitso

Lipeipi tsa SiC li tšehetsa mekhoa ea indasteri e sireletsang tikoloho:

（1）Polokelo ea Matla: Bokhoni bo phahameng ba mocheso bo fokotsa tšebeliso ea mafura ka sebōpi ka ho fihlela ho 20% ha ho bapisoa le lithebe tsa tšepe.

（2）Phokotso ea Litšila: Tšebeletso e telele e fokotsa litšila tsa thepa tse bakoang ke ho nkeloa sebaka khafetsa.

（3）Ho Fokotsa Chefo: Ho felisa tlhoko ea lipente tse kotsi (mohlala, li-alloy tse thehiloeng ho nickel) libakeng tse senyang.

Shandong Zhongpeng Special Ceramics Co., Ltd ke e 'ngoe ea litharollo tse kholo ka ho fetisisa tsa thepa e ncha ea silicon carbide Chaena. SiC technical ceramic: Bothata ba Moh ke 9 (Bothata ba Moh bo bocha ke 13), bo nang le khanyetso e ntle khahlanong le khoholeho le mafome, khanyetso e ntle - khanyetso le anti-oxidation. Bophelo ba tšebeletso ea sehlahisoa sa SiC bo bolelele ka makhetlo a 4 ho isa ho a 5 ho feta thepa ea alumina ea 92%. MOR ea RBSiC e feta ka makhetlo a 5 ho isa ho a 7 ho feta SNBSC, e ka sebelisoa bakeng sa libopeho tse rarahaneng haholoanyane. Ts'ebetso ea khotheishene e potlakile, phano e etsoa joalo ka ha e tšepisitsoe 'me boleng ha bo fete letho. Kamehla re phehella ho phephetsa lipheo tsa rona 'me re khutlisetsa lipelo tsa rona sechabeng.
