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

1. Hordhac

Silicon carbide crucibles waa aaladaha lagama maarmaanka u ah aasaaska, shaybaarrada, iyo hawlgallada shubista biraha iyada oo ay ugu wacan tahay kulaylkooda gaarka ah, caabbinta shoogga kulaylka, iyo awoodda ay u adkaysanayaan heerkulka ka sarreeya 1600°C. Si kastaba ha noqotee, xitaa carbide siliconka ugu adag waa la burburin karaa si degdeg ah ayuu u fashilmi karaa haddii aan si sax ah wax looga qaban. Haddii aad dhalaalayso aluminium, naxaas, ama biraha qaaliga ah, hagahan tallaabo-tallaabo ah ayaa kaa caawin doona inaad sida ugu fiican uga faa'iidaysato curiyahaaga adigoo iska ilaalinaya habab caadi ah.

2. Fahamka Crucible-kaaga Silicon-Carbide

Kahor intaadan quusin isticmaalka, waxaa muhiim ah in la ogaado waxa dejinaya a silsiladda carbide kala soocan. Waxa laga sameeyay carbide silikoon nadiif ah oo nadiif ah, weelashani waxay bixiyaan adkeysi sare marka loo eego garaafyada ama garaafyada dhoobada ah. Waxay inta badan ku wareersan yihiin alaabada kale ee dhoobada ah sida silikoon carbide dhoobada dhoobada, tiirarka dhoobada silikon carbide, ama xitaa suxuunta dubista silikoon carbide - laakiin kuwani waxay u adeegaan ujeedooyin kala duwan. Crucibles waxaa si gaar ah loogu farsameeyay haynta birta dhalaalaysa, ee ma aha qalabka wax lagu karsado ama dhismaha.

Waxa kale oo xusid mudan sida silicon carbide marka la barbar dhigo walxaha la midka ah. Tusaale ahaan, boron carbide vs silicon carbide: halka boron carbide ay adag tahay oo loo isticmaalo codsiyada hubka, way ka yar tahay kulaylka wayna ka qaalisan tahay - samaynta silikoon carbide go-to-ka-dabiiciga ah. Sidoo kale, silikoon nitride crucibles (badanaa laga helo warshadda silikoon nitride crucible) waxay bixisaa iska caabin shoog kulayl ah oo aad u wanaagsan laakiin waxaa sida caadiga ah loogu talagalay codsiyada gaarka ah sida farsamaynta semiconductor.

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

3.1 Diyaarinta Isticmaalka Hore

Had iyo jeer hubi kaaga silsiladda carbide ka samaysan dildilaaca, jajabka, ama cilladaha dhaldhalaalka ka hor inta aan la isticmaalin. Xataa burbur yar wuxuu u horseedi karaa masiibo guul darro ah kulaylka hoostiisa. Haddii ay tahay qolof cusub, samee si tartiib tartiib ah u kululaynta (sidoo kale loo yaqaan 'seasoning') si aad meesha uga saarto qoyaanka haraaga ah oo aad u yareyso diiqada gudaha.

• Ku rid weelka madhan foornada qabow ama foornada.
• Si tartiib ah kuleyl ilaa 200 ° C oo qabo 30 daqiiqo.
• Ka dibna kor u kac ilaa 600 ° C 2 saacadood oo qabooji saacad kale.
• Ugu dambeyntii, u keen heerkulka shaqadaada si tartiib tartiib ah.

3.2 Rarista iyo dhalaalinta

Weligaa ha xad-dhaafin weelka-buuxi wax ka badan 75% si aad uga hortagto daadad inta lagu jiro balaadhinta kulaylka. Isticmaal alaab nadiif ah oo qallalan si aad isaga ilaaliso soo saarista qoyaanka ama wasakhowga keeni kara qarax uumi ama falcelin kiimikaad. Iska ilaali si lama filaan ah heerkulka isbeddellada; had iyo jeer ku dar birta si tartiib ah oo siman.

3.3 Wax ka qabashada inta lagu jiro hawlgalka

Isticmaal qalabka kor u qaadida saxda ah ee loogu talagalay dhoobada heerkulka sare. Weligaa ha tuurin, garaacin, hana ku shubin shooladda shoogga makaanikada. Sidoo kale, iska ilaali inaad la xiriirto qulqulo ama jeexjeexyo aan ku habboonayn kuwaas oo daxdin kara matrixka silikoon carbide waqti ka dib.

4. Dhibaatooyinka caadiga ah iyo sida loo hagaajiyo

4.1 dildilaac ama dildilaac

Tani waxay badanaa ka dhalataa kuleyl degdeg ah ama qaboojin. Had iyo jeer raac jadwalka kor u qaadida iyo qaboojinta. Haddii foornadaadu ay ka maqan tahay xakamaynta heerkulka, tixgeli inaad isticmaasho kontaroolaha barnaamijka.

4.2 Dhaliilaha Dhallaanka ah ama Goynta

Dharbaaxada gardarrada ah ama soo-gaadhista soo noqnoqda ee daawaha qaarkood (sida zinc ama rasaasta) waxay baabi'in karaan dhaldhalaalka difaaca. U beddel qolof leh dahaar gaar ah ama hagaajin kiimikaad dhalaalaysa.

4.3 Cimriga oo la dhimay

Haddii crucible-ka silikoon-carbide-ku uu guul-darraysto dhowr adeegsi oo keliya ka dib, hubi borotokoolka kulayliyaha ka hor oo hubi inaadan dhaafin heerkulkeeda la qiimeeyay. Sidoo kale, hubi inaadan ku wareerin alaabada aan la xiriirin sida saxannada cashada ee silikoon carbide ceramik ama foornada foornada silikoon carbide-kuwa aan loogu talagalin birta dhalaalaysa!

5. Nadiifinta iyo Kaydinta

Isticmaalka ka dib, u ogolow in weelku uu si buuxda ugu qaboojiyo foornada ka hor inta aan la saarin. Waligaa ha ku damin biyaha. Si tartiib ah uga saar birta adag ama dharbaaxada adigoo isticmaalaya qalabka aan biraha ahayn-xarigga birta ah waxay keeni kartaa microfractures. Ku kaydi meel qalalan, nadiif ah oo ka fog qoyaanka iyo saamaynta jireed.

6. Goorta la Beddelayo Culfiifkaaga

Beddel qalabkaaga silikoon kaarbide haddii aad aragto dildilaacyo qoto dheer, dhumuc weyn oo gidaar ah, ama qallafsanaan. Ku sii wadida isticmaalka qashinka la isku halleyn karo waxay halis gelinaysaa birta daadsanaanta iyo khataraha badbaadada. Iyadoo alaabooyinka ay ka mid yihiin rbsic silicon carbide tile blocks ama silikoon carbide burner nozzles laga yaabo in ay wadaagaan hantida maaddada, laguma beddelan karo qashinka-mar walba isticmaal qaybta saxda ah ee shaqada.

7. Gunaanad

Qalab silikoon carbide crucible waa qalab wax qabad sare leh kaas oo keena kalsoonida marka si sax ah loo isticmaalo. Adigoo raacaya hababka kuleyliyaha saxda ah, rarista, iyo qaboojinta-iyo iska ilaalinta jaahwareerka ceramics silikoon carbide ah oo aan la xiriirin sida suxuunta dubista, tuubooyinka tuubooyinka, ama alaabta cashada - waxaad kordhin doontaa adeeggeeda waxayna hubin doontaa badbaado, hawlo hufan. Haddi aad is barbar dhigayso boron carbide vs silicon carbide ama aad baadhayso beddelaad kale sida gaashaanka kulaylka silikoon nitride, xasuusnoow: ku habboonaanta alaabtu waxay gebi ahaanba ku xidhan tahay codsigaga. Si taxadar leh ugu daawee weelkaaga, waxayna si fiican kuugu adeegi doontaa boqolaal dhalaalid ah.
