Sida Si Wanaagsan Loo Isticmaalo Oo Loo Ilaaliyo Crucible Silicon Carbide Si Looga Fogaado Guul-darrooyinka Guud?

1. Hordhac

Kaliya 24 saacadood ka hor, xarun weyn oo Ohio ah ayaa soo warisay in wax soo saarku uu istaagay sababo la xiriira soo noqnoqoshada silsiladda carbide Guuldarrooyinka burbursan inta lagu jiro dhalaalidda aluminium-xusuusinta sida muhiimka ah ee maaraynta saxda ah ay ugu tahay dhoobadan waxqabadka sare leh. Silicon carbide crucibles waxaa lagu qiimeeyaa kuleylkooda gaarka ah, caabbinta shoogga kulaylka, iyo awoodda u adkeysiga heerkulka ka sarreeya 1600 ° C. Hase yeeshee, xitaa qalabka silikoon carbide crucible ee sida ugu fiican loo sameeyay ayaa dillaaci kara, hoos u dhigi kara, ama dhalaali kara haddii si khaldan loo isticmaalo.

Haddi aad ku sugan tahay biraha, cilmi baadhista shaybaadhka, ama kabka farsamada gacanta, hagahani waxa uu kugu dhex marayaa talaabooyin wax ku ool ah oo aad isticmaasho sii wad Silicon carbide crucible si wax ku ool ah — ka fogaansho khaladaadka qaaliga ah iyo wakhtiga dhimista.

2. Fahamka Crucible-kaaga Silicon-Carbide

Kaaraynta Kalluunka (SiC) waa iskudhis silikoon iyo kaarboon ah oo caan ku ah adayga iyo xasilloonida kulaylka. Qalab silikoon carbide ah ayaa sida caadiga ah laga sameeyaa SiC sinteed ama silikoon carbide ah oo falcelin ku xidhan (RBSiC), oo bixisa waxqabad heersare ah oo ka sarreeya dhoobada-graphite-ka dhaqameed ama alumina.

Waxaa xusid mudan in marka silikoon carbide aad ayey ugu fiican tahay codsiyo badan, beddelaadyo sida silikoon nitride crucibles — oo ay soo saaraan warshado gaar ah oo silikoon nitride crucible — ayaa laga yaabaa inay u fiicnaadaan dhalaalid falcelineed gaar ah. Sidoo kale, marka la is barbar dhigo boron carbide vs silicon carbide, boron carbide waa ka adag tahay laakiin waa ka jaban yahay oo waa qaali, taasoo ka dhigaysa SiC ta loo isticmaalo inta badan warshadaha.

3. Tillaabo-Tallaabo Hagaha Isticmaalka Kaarbide Silicon-Carbide Crucible

3.1 Si tartiib ah u kulayl

Waligaa ha dhigin karbide silikoon qabow waa la burburin karaa si toos ah foorno kulul. Naxdinta kulaylka ayaa ah sababta #1 ee dildilaaca. Bedelkeeda, si tartiib ah kor ugu qaad heerkulka: ka bilow 200-300C ilaa 30 daqiiqo, ka dibna ku kordhi 100-150 ° C 15-20 daqiiqo kasta ilaa aad gaarto heerkulka bartilmaameedka ah.

3.2 Si taxadar leh ugu shub alaabta

Ka fogow inaad ku riddo biraha birta ah ama qashinka ku rid weelka. Isticmaal suumanka ama dambiilaha wax lagu dallaco si aad si tartiib ah u dhigto alaabta. Saamaynta fiiqan waxay jajabin kartaa gudaha, gaar ahaan naqshadaha derbiyada dhuuban sida tiirarka dhoobada ee silikoon carbide ama giraanta.

3.3 Iska ilaali buuxinta

Buuxi kaliya 70-80% awoodda Birta dhalaalaysa way balaadhataa, firidhashadu waxay baabi'in kartaa darbiyada dillaacsan ama waxay keeni kartaa daad. Tani waxay si gaar ah muhiim u tahay marka la dhalaalayo alloysyada falcelinta.

3.4 Adeegso Fluxes iyo Wax-ka-dheerayaasha Wanaagsan

Qaar ka mid ah qulqulka waxaa ku jira alkalis oo si adag uga falcelisa SiC. Had iyo jeer hubi ku-waafajinta kiimikada. Codsiyada nadiifnimada sare leh, tixgeli inaad isticmaasho saxan silikoon nitride ama gaashaan kulaylka silikoon nitride caado ahaan caqabad ahaan.

4. Qaboojinta iyo Kaydinta Hababka ugu Wanaagsan

Isticmaalka ka dib, u ogolow in weelku uu si dabiici ah ugu qaboojiyo gudaha foornada iyadoo korontadu ay dansan tahay. Hawada qasabka ah ama qaboojinta biyaha waxay keeni kartaa jajabyo yaryar. Marka la qaboojiyo heer ka hooseeya 100 ° C, ka saar oo ku kaydi meel engegan oo aan boodh lahayn.

Waligaa ha ku rarin weel ama ha saarin walxo culus dushooda. Xataa foomamka adag sida leben carbide silicon ama RBSiC silikoon carbide block block waxay horumarin kartaa dildilaaca cadaadiska hoostiisa.

5. Dhibaatooyinka guud iyo xalalka

5.1 dildilaac ama dildilaac

Sababta: Kuleyl degdeg ah / qaboojin ama saameyn farsamo. Xalka: Raac borotokoollada tartiib-tartiibka ah oo si taxadar leh ula qabso.

5.2 dhalaalid ama Dhisidda Gudaha

Sababta: Isticmaalka soo noqnoqda ee alwaaxyada qaarkood (tusaale, aluminium) waxay samaysaa lakab quraarad ah. Xalka: Ku nadiifi buraash jilicsan ama xoqin khafiif ah sida saxanka wax lagu shiido silikoon carbide-waligaa ha isticmaalin dhogor bir ah.

5.3 Cimriga oo la dhimay

Sababta: Isticmaalka weel ka baxsan heerkulka la qiimeeyay ama qalab aan ku habboonayn. Xalka: Hubi noocyada soo saaraha; baahiyaha nadaafadda aadka u saraysa, sahamiya silikoon nitride nadiif ah oo nadiif ah oo baddalkeeda ah suuqa.

6. Ka baxsan Crucibles: Alaabta kale ee Silicon Carbide dhoobada

In kasta oo hagahan uu diiradda saarayo saqafyada, kala duwanaanshaha silikoon carbide waxa ay fidisaa qaabab badan. Waxaad ka heli doontaa suxuunta dubista dhoobada silikoon carbide, saxannada cashada dhoobada ee silikoon carbide, iyo xitaa suxuunta subagga dhoobada ee silikoon carbide ee ku jira weelka sare ee cuntada lagu kariyo. Goobaha warshadaha, tuubooyinka silikoon carbide gubida, tuubooyinka silikoon carbide ee foornooyinka, iyo tuubooyinka dhoobada silikoon carbide waa caan.

Tuubooyinka ama xakamaynta dareeraha, qaybaha sida qasabadaha silikoon carbide ceramic disc tuubooyinka iyo silikoon carbide ceramic diskka tuubada tuubada waxay soo bandhigaan iska caabin. Dhanka kale, saxanadaha silikoon carbide iyo saxanadaha wax lagu shiidi karo silikoon carbide dhoobada ayaa si weyn loogu isticmaalaa dhoobada iyo mashiinada.

7. Gunaanad

Qalab silikoon carbide crucible waa qalab awood leh-laakin kaliya haddii loola dhaqmo si ixtiraam leh xadka alaabta. Adigoo raacaya kuleyliyaha saxda ah, rarida, qaboojinta, iyo nadiifinta joogtada ah, waxaad u kordhin kartaa nolosheeda si weyn waxaadna xaqiijin kartaa natiijooyin joogto ah, oo aan wasakh ahayn. Haddii aad dhalaalayso biraha, tijaabinta shaybaadhka, ama sahaminta alaabta cuntada ee dhoobada ah sida silikoon carbide dhoobada u adeegta maddiibado ama taarikada silikoon carbide buluug cad, fahamka aasaasiga ah ee daryeelka SiC waxay bixisaa waxqabadka iyo kaydinta kharashka.
