Amandla aphezulu we-silicon carbide ceramic tube SIC izinhlobo ezahlukene ngokwezifiso ukumelana nomlilo Isithombe esifakiwe

Incazelo emfushane:

I-Silicon carbide ceramic tube iwuhlobo lwepayipi elenziwe nge-silicon carbide (SiC) njengengxenye eyinhloko yezinto zobumba. Inqubo yokukhiqiza ihlanganisa ukucushwa kwempushana, ukulungiswa kwedivayisi, ukugcwaliswa kwempushana, ukucindezela okubandayo kwe-isostatic, ukuqedwa kokusika okuyisisekelo kanye nokushisa okuphezulu kwe-sintering. Lelipayipi linomthamo omkhulu, ukunemba okuphezulu kwemishini kanye nesakhiwo esifanayo, esingahlangabezana nezidingo zezindawo ezinembayo eziphezulu, njengemboni yenuzi.

Ubukhulu. Izinga Lokushisa Lokusebenza	1650ºC

Izici eziyinhloko:

I-1.Amandla aphezulu kanye nobunzima obuphezulu: Ithubhu ye-silicon carbide ceramic inamandla aphezulu kakhulu nobulukhuni, ingakwazi ukumelana nokushisa okuphezulu kanye nendawo yokucindezela okuphezulu.
I-2.Ukumelana nokugqwala: Ukumelana nokugqwala kwayo okuhle kakhulu kuyenza ifanelekele ukugqwala okuphezulu kanye nezindawo zokugqoka.
3.I-Low friction coefficient: Ishubhu le-silicon carbide ceramic line-coefficient ephansi ye-friction, ifanele izikhathi lapho ukungqubuzana kudinga ukuncishiswa.
4. Ukushisa okuphezulu kwe-thermal: I-silicon carbide ceramic tube ine-conductivity ephezulu ye-thermal, ingadlulisela ngempumelelo ukushisa.
5. Izici ze-Antioxidant: Ezimweni zokushisa okuphezulu, amashubhu e-silicon carbide ceramic abonisa izici ezinhle kakhulu ze-antioxidant.

Izinhlelo zokusebenza eziyinhloko:

I-1.Standard sapphire fiber: Ububanzi bobubanzi buvamise ukuba phakathi kuka-75 no-500μm, futhi ubude buyahlukahluka kuye ngobukhulu.

I-2.I-conical sapphire fiber: I-taper ikhulisa i-fiber ekugcineni, iqinisekisa ukuphuma okuphezulu ngaphandle kokudela ukuguquguquka kwayo ekudlulisweni kwamandla kanye nezicelo ze-spectral.

Izindawo zokufaka izicelo eziyinhloko

1.Imboni yeNuclear: Ngenxa yokuminyana kwayo okuphezulu kanye nokumelana nokugqwala, amashubhu e-silicon carbide ceramic asetshenziswa kakhulu kumapayipi okupholisa kanye nokuhlanganisa uphethiloli kuma-reactors enuzi.
I-2.I-Aerospace: Amashubhu e-ceramic e-silicon carbide asetshenziselwa ukwakhiwa kwezingxenye zenjini yendiza kanye nezingxenye ze-spacecraft ngenxa yesisindo sazo esingasindi, amandla aphezulu kanye nokumelana nokushisa okuphezulu.
I-3.Imishini yokushisa ephezulu: Ezithandweni zokushisa eziphakeme, izinzwa zokushisa okuphezulu kanye nama-reactors okushisa aphezulu, amashubhu e-silicon carbide ceramic asetshenziswa kakhulu ngenxa yokumelana nokushisa okuphezulu nokumelana ne-oxidation.
4. Izinto zikagesi zamandla: amashubhu e-silicon carbide ceramic angasetshenziswa ukwenza izinto zokupakisha zamadivayisi kagesi ukuze kuthuthukiswe ukusebenza kahle kokukhipha ukushisa nokuthembeka kwamadivayisi.
5. Izimoto zamandla amasha: Ezimotweni zamandla amasha, amashubhu e-silicon carbide ceramic angasetshenziswa ukwenza izingxenye ezibalulekile ohlelweni lokuphatha amabhethri ukuze kuthuthukiswe ukuzinza nokuphepha kwesistimu.
I-XKH inikezela ngezinsiza ezibanzi ze-bespoke zamashubhu e-silicon carbide ceramic, kusukela ekukhethweni kwezinto ezibonakalayo nokwakheka kobukhulu kuya ekuphathweni kwangaphandle, iqinisekisa ukuthi imikhiqizo ihlangabezana nezidingo ezithile zamakhasimende.
I-1.Ngokwezinto zokwakha, izinto zokusetshenziswa ze-silicon carbide zokuhlanzeka okuhlukene kanye nosayizi wezinhlayiyana zingakhethwa ngokuvumelana nezidingo zamakhasimende ukuze kuhlangatshezwane nezimo ezihlukene zohlelo lokusebenza ezifana nokushisa okuphezulu, ukumelana nokugqwala noma amandla aphezulu.
2.Ngokwesakhiwo sosayizi, isekela ukwenziwa ngokwezifiso kwamadayimitha angaphakathi ahlukahlukene, ububanzi bangaphandle nobude, futhi ingakwazi ukuklama ubujamo obuyinkimbinkimbi nezakhiwo ngokuvumelana nezidingo zamakhasimende, njengamapayipi amise okukhethekile, amapayipi anezimbobo noma izinsimbi zamapayipi ezinama-flange.
3.Mayelana nokwelashwa okungaphezulu, ukupholisha, ukumboza (okufana ne-antioxidant coating noma ukumelana nokuguga) nezinye izinqubo kunikezwa ukuze kuthuthukiswe ukumelana nokugqwala, ukumelana nokugqokwa noma ukuphela kwendawo yomkhiqizo.
Kungakhathaliseki ukuthi iku-semiconductor, amakhemikhali, i-metallurgy noma ukuvikelwa kwemvelo, i-XKH ingahlinzeka amakhasimende ngamashubhu e-ceramic enziwe ngomthungo wekhwalithi ephezulu we-silicon carbide kanye nezisombululo ezisekelayo.
