Sawirka Soo-bandhigga Tuubada Kaarboohaydraytka ee Silicon Carbide

Koonka Tuubada Kaarboohaydraytka ee Silicon

Sharaxaad Gaaban:

Tuubada tuubada carbide-ka ee silikoon alpha ee silikoonka ah waxaa lagu soo saaraa iyadoo la isticmaalayo budada sub-micron ee aadka u saafi ah. Budadan waxaa lagu qasaa qalabka silikoonka ee aan oksaydhka ahayn, ka dibna waxaa loo sameeyaa qaabab adag iyadoo la adeegsanayo habab kala duwan waxaana lagu xoojiyaa silikoon heerkulka ka sarreeya 3633 darajo Fahrenheit.

Habka sintering-ku wuxuu keenaa hal-marxalad oo silikoon ah oo jilicsan oo aad u saafi ah oo isku mid ah, iyada oo aan lahayn daloolo u oggolaanaya agabku inay u adkeystaan deegaanka daxalka leh, deegaannada xoqan, iyo deegaannada ku shaqeeya heerkulka sare (2552 darajo Fahrenheit). Sifooyinkani waxay ka dhigaan sintered alpha silicon carbide ku habboon codsiyada sida dahaarka tuubooyinka, dahaarka duufaanta.

Faahfaahinta Badeecada

Astaamaha Badeecada:

– Cufnaan yar, Awood sare.
– Xoog heerkul sare oo wanaagsan (Falcelin isku xiran).
– Iska caabbinta oksaydhka (Falcelinta oo isku xidhan).
- Iska caabinta shoogga kulaylka oo aad u fiican.
- Adkayn sare iyo iska caabin xirasho.
– Iska caabin kiimiko oo aad u fiican.
- Ballaarinta kulaylka oo hooseysa iyo gudbinta kulaylka oo sareysa.

Codsiga Badeecada:

Koonka tuubada carbide-ka ee silikoon waa badeeco carbide silikoon ah oo leh qaab iyo cabbir gaar ah, meelaha loo adeegsadona waa ballaaran yihiin oo kala duwan yihiin.
1) Gudbinta dareeraha jawiga heerkulka sare: Iska caabbinta kulaylka iyo iska caabbinta xirashada ee Silicon carbide waxay ka dhigaysaa mid ku habboon nidaamyada gudbinta dareeraha ee jawiga heerkulka sare, sida dhuumaha gaasaska heerkulka sare, dareerayaasha iyo walxaha granular-ka ah ee kiimikada, birta iyo meelaha kale.

2) Qaybaha farsamada ee saxda ah: Adkeysiga sare ee carbide-ka iyo iska caabbinta xirashada ayaa ka dhigaya agab ku habboon soo saarista qaybaha farsamada ee saxda ah. Tusaale ahaan, qaybo sax ah oo ka mid ah mashiinnada sawir-qaadista ayaa laga yaabaa inay qaataan naqshadeynta qaabka koonka tuubada carbide-ka ee silicon.

3) Adeegsiyo kale oo gaar ah: Sida waafaqsan baahiyaha gaarka ah, koonooyinka tuubooyinka carbide ee silicon ayaa sidoo kale loo isticmaali karaa meelo kale oo gaar ah, sida hawada sare, warshadaha nukliyeerka, iwm.
