Sida Si Wanaagsan Loo Isticmaalo oo Loo Ilaaliyo Crucible Silicon Carbide: Hagaha Tallaabo-tallaabo

1. Hordhac

Silikoon carbide crucibles ayaa lagu qiimeeyaa labadaba warshadaha iyo goobaha farshaxanimada si ay ula dhaqmaan kulaylka aan caadiga ahayn, u adkeysiga shoogga kulaylka, iyo awoodda u adkeysiga heerkulka ba'an-badanaa ka sarreeya 1600°C (2912°F). Haddii aad dhalaalayso biraha, dhoobada ridaya, ama aad tijaabinayso shaybaadhka, adiga oo garanaya sida saxda ah ee loo maareeyo Silicon carbide crucible waxay si weyn u kordhin kartaa cimrigeeda waxayna xaqiijin kartaa waxqabad joogto ah.

Tilmaan-bixiyahan, waxaanu kugu socon doonaa hab-raaca tallaabo-tallaabo ee isticmaalka iyo ilaalinta silikoonkaaga carbide cufan. Waxaan sidoo kale wax ka qaban doonaa dhibaatooyinka caadiga ah, is barbar dhig silikoon carbide iyo beddelaad kale sida boron carbide vs silicon carbide iyo silicon nitride, oo si kooban u sahamin doonaa qoyska ballaaran ee silikon carbide dhoobada alaabta - laga bilaabo suxuunta dubista ilaa tubooyinka foornada.

2. Diyaarinta Crucible-kaaga Silicon-Carbide ee Isticmaalka Koowaad

Kahor intaadan isticmaalin silikoon cusub carbide malaha, waa lagama maarmaan in si habboon loo hagaajiyo. Tani waxay ka hortagtaa shoogga kulaylka iyo microcracking inta lagu jiro hawlgallada heerkulka sare.

• Ka eeg weelka dillaacsan, jajabka, ama cilladaha dusha sare. Xitaa waxyeelada yar ayaa ka sii dari karta kulaylka.
• Ku nadiifi gudaha burush jilicsan si aad uga saarto boodhka wax soo saarka ama qashinka.
• Samee si tartiib tartiib ah toogashada ka hor (sidoo kale loo yaqaan 'seasoning') adiga oo ku kululeynaya weelka maran si tartiib ah foornadaada ama foornadaada: ku bilow 200 ° C ilaa 30 daqiiqo, ka dibna kor u kac ilaa 600 ° C, qabo 30 daqiiqo oo kale, oo ugu dambeyntii gaarto heerkulka aad ugu talagashay inaad ku shaqeyso 1-2 saacadood.

Kor-u-qaadistan tartiib-tartiib ah waxay u oggolaanaysaa qoyaanka iyo xirmooyinka inay si badbaado leh u gubaan, taasoo yaraynaysa khatarta dillaaca ama dillaaca.

3. Kuleyliyaha badbaadada leh iyo Dhaqanka Isticmaalka

Marka dhadhanka, silikoonkaaga kaarbiid crucible wuxuu diyaar u yahay isticmaalka joogtada ah - laakiin farsamada saxda ah ayaa weli ah mid muhiim ah.

• Had iyo jeer ku dheji weelka dusha sare ee deggan, kulaylka u adkaysta sida leben carbide silicon ama looxa fiber dhoobada ah.
• Iska ilaali isbeddelada heerkulka degdega ah. Waligaa walxo qabow ha ku darin weel kulul ama ku shub biyo kulul ha gelin.
• Marka aad dhalaalayso biraha ama dhalada, buuxi weelka wax aan ka badnayn saddex-meelood laba meel si aad uga hortagto qulqulka oo aad u yarayso walbahaarka farsamada.
• Isticmaal qalab ku habboon — oo doorbidan in laga sameeyo graphite ama silicon carbide — si aad u kiciso ama u xakamayso waxa ku jira. Qalabka birta ahi waxay xoqin karaan ama wasakhayn karaan dahaarka aan la karin.

Xusuusnow: silicon carbide waxa uu ku fiican yahay oksaydhaynta iyo jawiga dhexdhexaadka ah laakiin waxa uu hoos u dhigi karaa jawi hoos u dhac xoog leh muddo ka dib.

4. Nadiifinta iyo Dayactirka

Nadiifinta saxda ah waxay ilaalisaa daacadnimada silikoon carbide crucible-kaaga waxayna ka hortagtaa faddaraynta.

• U ogolow in weelku uu si buuxda u qaboojiyo ka hor inta aanad nadiifin - waligaa ha damin.
• Ka saar haraaga adag adiga oo si tartiib ah u taabanaya ama isticmaalaya xoqin aan bir ahayn. Kordhis adag, kuleyl weelka si uu u kululaado oo hadhaaga hadhaagaan ama ay bakhtiiyaan.
• Ka fogow biyaha ama nadiifiyeyaasha kiimikaad ilaa daruuri mooyaane. Haddii loo baahdo, isticmaal saabuunta khafiifka ah oo si fiican u biyo raaci, ka dibna si buuxda u qalaji ka hor inta aanad dib u isticmaalin.

Ku kaydi weelkaaga meel engegan oo aan boodh lahayn. Isku-dubbarididdu waxay sababi kartaa jajab - isticmaal weel gaar ah haddii ay suurtogal tahay.

5. Dhibaatooyinka guud iyo xalalka

Xataa daryeelka, arrimo ayaa soo bixi kara. Waa kan sida loo xalliyo iyaga:

• Dilaac ama dildilaacSida caadiga ah waxaa keena shoogga kulaylka. Had iyo jeer si tartiib tartiib ah u kululee kana fogow qaboojin degdeg ah.
• glazing ama vitrification oogadaWaxay dhacdaa marka dareeraha ama alaabta dhalaalaysa ay la falgalaan qolofka. Isticmaal dahaar ilaalin ah ama u beddel silikoon carbide oo nadiif ah oo sare leh.
• Cimrigu hoos u dhacay: Waxa laga yaabaa inay muujiso jawiga aan is qaadan karin (tusaale, soo-gaadhista daba dheeraada ee hydrogen ama carbon monoxide). Tixgeli beddelka sida warshadda silikoon nitride crucible si loo yareeyo xaaladaha.

Haddii codsigaagu uu ku lug leeyahay daxalka xad-dhaafka ah ama shuruudaha daahirsanaanta aadka u sarreeya, barbar dhig silikoon carbide iyo fursadaha dhoobada silikoon nitride-sida gaashaan kulaylka silikoon nitride caado ah ama saxan silikoon nitride-kaas oo bixiya qallafsanaan kiimiko oo heersare ah deegaanno gaar ah.

6. Ka baxsan Crucibles: Kala-duwanaanta Ceramics Silicon Carbide

In kasta oo hagahan uu diiradda saarayo meelaha la isku qurxiyo, tamarta silikoon carbide waxay ka kooban tahay qaabab badan. Isticmaalayaasha warshaduhu waxay inta badan ku lammaaniyaan weel-sharafeedyo leh waxyaabo la xidhiidha sida tuubooyinka dhoobada silikoon carbide ee loogu talagalay isticmaalka foornada, tuubooyinka ilaalinta heerkulbeegga silikon carbide, ama dhoobada dhoobada silikoon carbide ee daboolka kiln.

Cuntooyinka cuntada, waxaad ka heli doontaa suxuunta dubista dhoobada silikoon carbide, saxannada cashada dhoobada ee silikoon carbide, iyo xitaa suxuunta subagga dhoobada ee silikoon carbide-oo lagu qiimeeyay xitaa kuleylka iyo adkeysiga. Alaabooyinka ay ka mid yihiin saxanka dubista ee silikoon carbide ama saxanka dheriga silikoon carbide dhoobada leh ee daboolka leh waxay isku daraan waxqabadka qurxinta.

Codsiyada kale ee niche waxaa ka mid ah saxanadaha silikoon carbide ee wax lagu shiidi karo, qasabadaha silikoon carbide dhoobada tuubooyinka, iyo tiirarka dhoobada silikoon carbide ee nidaamyada sifaynta. Haddii aad u baahan tahay shaabadadaha silikoon carbide, nozzles silicon carbide gubanaya, ama tuubooyinka dhoobada ee silikoon carbide, engeganaanta alaabta iyo xasiloonida kulaylka ayaa ka dhigaysa doorasho-doorasho.

7. Gunaanad

Qalab silikoon carbide crucible waa qalab awood leh-laakin waa haddii si sax ah loo isticmaalo. Adigoo raacaya xawaash habboon, kuleyl, nadiifin, iyo borotokoolka kaydinta, waxaad sare u qaadi kartaa adeeggeeda iyo waxqabadkeeda. Marka xaaladuhu ay dalbadaan waxyaabo kale, fahamka farqiga u dhexeeya boron carbide vs silicon carbide ama sahaminta fursadaha nitride silikoon (sida giraanta nitride silikoon ama alaabada suuqa budada silikoon nitride saafi ah oo sarreeya) waxay hubinaysaa inaad dooratid alaabta saxda ah ee baahiyahaaga.

Laga soo bilaabo aasaaska warshadaha ilaa jikooyinka farsamada gacanta, silikoon carbide waxay sii wadaa inay caddayso qiimaheeda codsiyo kala duwan oo cajiib ah - taasoo ka dhigaysa mid ka mid ah dhoobada ugu horumarsan ee la heli karo maanta.
