Tuubbada ilaalinta silikon carbide

Warshadaha halkaas oo xaaladaha ba'an ay khatar ku yihiin daacadnimada qalabka,Silicon carbide (SiC) tuubooyinka ilaalintasoo ifbaxa sidii xal asaasi ah. Si ka duwan agabka gaashaandhigga caadiga ah, tuubooyinka SiC waxay isku daraan sayniska agabka sare iyo injineernimada adag si loo ilaaliyo aaladaha iyo hababka muhiimka ah.Waxay leedahay faa'iidooyinka soo socda:

1. Ilaalinta aan isbarbar dhigin ee xaaladaha colaadeed

Tuubooyinka ilaalinta ee SiC waxay u dhaqmaan sidii safka koowaad ee difaaca meelaha aan guuldarradu ahayn ikhtiyaar:

(1) Difaaca kulaylka: U adkeyso heerkulka joogtada ah ilaa 1600°C, dareemaha gaashaanka, kulaylaha, ama baarayaasha biraha dhalaalay, ololka, iyo balaasmaha.

(2) Difaaca Kiimikada: Iska ilaali daxalka aashitada (tusaale sulfuric, hydrochloric), alkalis, iyo gaasas fal-celin ah sida koloriin ama sulfur oxides.

Iska-caabbinta Abrasion: Ka ilaali walxaha naxsiga leh ee sariiraha dareeraha leh, gaasta dhuxusha, ama hawlaha macdanta.

2. Saxnaanta iyo Xasiloonida Cabiraadyada Muhiimka ah

Nidaamyada warshadaha ee sarreeya, saxnaanta ayaa muhiim ah. Tuubooyinka SiC waxay xoojiyaan isku halaynta iyagoo:

(1) Yaraynta Faragelinta Calaamadaha: Guryaha aan shaqaynayn waxay ka hortagaan carqaladaynta korantada ee dareemayaasha elektiroonigga ah.

(2) Xasiloonida kulaylka: Qallafsanaanta kulaylka ee eber-ku dhow waxay hubisaa toosinta joogtada ah iyo saxnaanta cabbirka ee hoos u dhaca heerkulka degdega ah.

(3)Gaas-ku dheggan daacadnimada: Qaabka aan la taaban karin ayaa ka hortagaya gaaska soo dhex gala, muhiim u ah nidaamyada faakuumka ama jawiga la kantaroolo.

3. Fududeynta Jiilka Xiga ee Tiknoolajiyada Tuubooyinka ilaalinta ee SiC waxay furayaan hal-abuurnimo meelaha soo baxaya:

(1) Dhaqaalaha Hydrogen: U adeega sida galalka waara ee dareemayaasha ku jira soo saarista hydrogen, kaydinta, iyo unugyada shidaalka, iska caabbinta embrittlement iyo cadaadiska sare ee H₂.

(2) Wax-soo-saarka Semiconductor: Ka ilaali dareemayaasha indhaha iyo kulaylka ee CVD (Chemical Vapor Deposition) fal-celiyeyaasha ka soo horjeeda horudhaca sida silane ama ammonia.

(3) Sahminta Goobta: Qalabka gaashaanka ee matoorada gantaallada iyo meerayaasha meeraha ee ka imanaya heerar kuleyl oo aad u daran iyo shucaaca koofiyadaha.

4. Kharash-wax-ku-oolnimada iyada oo loo marayo cimri-dherer

Iyadoo tubooyinka SiC ay leeyihiin kharashyo hore oo sarreeya, faa'iidooyinkooda meertada nololeed ayaa dib u qeexaya qiimaha:

(1) Hoos u dhaca wakhtiga: Beddelka birta ama quartz ee ka dambeeya 4-6x goobaha xoqida ama aashitada, yaraynta dayactirka aan la qorshayn.

(2) Shuruudaha Dahaarka eber: Si ka duwan biraha u baahan dahaar ilaalin, SiC's's's's's's's's's's's's's's's's internaltu wuxuu baabi'iyaa kharashka daaweynta dusha soo noqnoqda.

(3) Dib-u-isticmaalka: Ka badbaado habab badan oo wareegyo ah oo ku jira codsiyada sida birta tuurista ama dhalooyinka samaynta iyada oo aan hoos u dhicin.

5. Habaynta Baahiyaha Gaarka ah

Tuubooyinka ilaalinta ee SiC waxay la qabsadaan caqabadaha niche iyada oo loo marayo injineernimo habaysan:

(1) Naqshadaynta Isku-dhafan: Isku-dhafka biraha ama dhoobada loogu talagalay shirarka hawl-fulinta badan (tusaale xirayaasha dunta, flanges).

(2) Wax ka beddelka dusha sare: Gudaha oo la sifeeyay oo loogu talagalay codsiyada indhaha ama dibadda textured si kor loogu qaado daadinta kulaylka.

(3) Dabacsanaanta Cabbirka: Waxaa laga soo saaray millimitir (xajiyeyaasha shaybaadhka) ilaa mitir (kilns warshadeed).

6. Iswaafajinta Joogtada

Tuubooyinka SiC waxay taageeraan dhaqamada warshadaha ee saaxiibtinimo ee deegaanka:

(1) Kaydinta tamarta: Hufnaanta kulaylka sare waxay yaraynaysaa isticmaalka shidaalka foornada ilaa 20% marka la barbar dhigo gaashaanka birta.

(2) Dhimista Qashinka: Nolosha adeegga oo dheer waxay dhimaysaa qashinka alaabta beddelka ah ee joogtada ah.

(3) Yaraynta Sunta: Baabi'in baahida dahaarka khatarta ah (tusaale, aluminium-ku-salaysan nikkel) ee meelaha daxalka leh.

Shandong Zhongpeng Ceramics Co., Ltd waa mid ka mid ah xalalka alaabta cusub ee silikoon carbide ugu weyn ee Shiinaha. dhoobada farsamada ee SiC: Adkeeyga Moh waa 9 (Adayga cusub ee Moh waa 13), oo leh iska caabin aad u wanaagsan oo nabaadguurka iyo daxalka, nabaad-guurka heersare ah - iska caabin iyo anti-oxidation. Nolosha adeegga sheyga SiC waa 4 ilaa 5 jeer in ka badan 92% walxo aluminium ah. MOR ee RBSiC waa 5 ilaa 7 jeer ka SNBSC, waxa loo isticmaali karaa qaabab aad u adag. Habka xigashada waa mid degdeg ah, gaarsiinta waa sidii balanta ahayd, tayaduna waa labaad ee midna. Had iyo jeer waxaan ku adkaysannaa inaan ka hortagno yoolalkayaga oo aan dib u soo celinno quluubtayada bulshada.
