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

1. Hordhac

48-kii saacadood ee la soo dhaafay, alaab-qeybiye warshadeed oo weyn ayaa ku dhawaaqday yaraanta adduunka ee nadiifinta sare silsiladda carbide alaabada ceyriinka ah oo ay ugu wacan tahay khalkhalgelinta silsiladda sahayda ee Koonfur-bari Aasiya-horumar kicinaya xiisaha dib u cusboonaysiinta daryeelka saxda ah ee ku habboon si loo kordhiyo nolosha adeegga. Haddi aad ku jirto cilmi-baadhista birta, muraayad-samaynta, ama shaybaadhka sare, qalabkaaga silikoon carbide crucible waa qalab muhiim ah-iyo qaali ah. Hagahan waxa uu ku siinayaa tillaabooyin la fulin karo oo aad si sax ah u isticmaasho oo aad u ilaaliso.

2. Fahamka Crucible-kaaga Silicon-Carbide

A silsiladda carbide Crucible waxaa lagu qiimeeyaa kuleylkeeda gaarka ah, caabbinta shoogga kulaylka, iyo awoodda u adkeysiga heerkulka ka sarreeya 1600°C (2912°F). Si ka duwan sida lakabyada dhoobada-graphite-ka caadiga ah, silikoon carbide waxay bixisaa adkeysiga sare ee jawiga oksidaynta, taasoo ka dhigaysa mid ku habboon dhalaalidda biraha aan birta ahayn sida aluminium, copper, iyo zinc.

Waa muhiim inaan la jahawareerin silicon carbide leh qalab dhawaaqa la mid ah. Tusaale ahaan, boron carbide vs silicon carbide: halka labaduba ay yihiin dhoobada ultra-adag, boron carbide inta badan waxaa loo isticmaalaa hubka iyo abrasives, ma aha qolofyada. Sidoo kale, alaabada warshadda silikoon nitride crucible waxay u adeegtaa codsiyada walaaca sare leh laakiin guud ahaan way ka qaalisan yihiin oo ka dabci ahaan ka yar yihiin fursadaha silikoon carbide.

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

3.1. Kormeerka Kahor Isticmaalka

Kahor isticmaalka ugu horreeya-ama ka dib kaydinta-baari kaaga silicon Kaarbiide crucible ee dildilaaca, jajabka, ama dhaldhalaalka dusha sare. Xataa jebinta timaha waxay u horseedi kartaa fashilaad ba'an oo kulaylka hoostiisa ah. Sidoo kale iska hubi hadhaaga dhalaalkii hore; si fiican u nadiifi haddii loo baahdo.

3.2. Qalajinta saxda ah iyo kulaylka ka hor

Waligaa ha dhigin qabow ama qoyan waa la burburin karaa si toos ah foorno kulul. Qoyaanka ku xayiran matrixka dhoobada ayaa ku soo biligmi kara uumiga oo sababi kara dildilaac. Halkii:

• Ku qallaji 110°C (230°F) 2-4 saacadood haddii lagu kaydiyo xaalado qoyan.
• Si tartiib tartiib ah ugu kululee foornada: kor u kac 100-150 ° C saacaddii ilaa laga gaarayo 600 ° C, qabo 30 daqiiqo, ka dibna u gudub heerkulka shaqada.

3.3. Soo rarista iyo dhalaalidda

Buuxi weelka wax ka badan 75% buuxa si aad uga hortagto daadinta inta lagu jiro balaadhinta kulaylka. Isticmaal agabka dallacaadda la socon kara—ka fogow inaad soo bandhigto chlorides ama fluoride, taasoo daxalaynaysa karbidhida silikon xilli ku meel gaar ah. Si tartiib ah ugu walaaq ulaha carbide silikoon, ma aha qalabka birta, si aad isaga ilaaliso wasakhda iyo dhaawaca farsamada.

4. Dhibaatooyinka guud iyo xalalka

4.1. Dilaac ama dildilaac

Sababta: Heerkulka degdega ah ayaa isbeddela ama shoog farsamo. Xalka: Had iyo jeer raac si tartiib tartiib ah wareegyada kuleylka / qaboojinta. Weligaa ha ku damin weel kulul oo biyo ah.

4.2. Samaynta Dhallaalka ama Dhisida Slag

Sababta: Ka falcelinta qulqulka ama wasakhda. Xalka: Isticmaal alaab saafi ah oo nadiif ah. Isticmaal kasta ka dib buraash jilicsan ku nadiifi—waligaa ha isticmaalin qashinka birta ah.

4.3. Cimriga oo yaraatay

Haddi weelkaagu uu hore u fashilmo, hubi jawiga foornadaada. Silikon carbide waxa ay si fiican u qabataa xaalad dhexdhexaad ah ama wax yar yaraynaysa. Deegaannada oksaydhaynta xooggan, lakabka silica-ka difaaca ayaa samaysma laakiin wuu yarayn karaa muddo ka dib.

5. Nadiifinta iyo Kaydinta

Kadib markaad si buuxda u qaboojiso, ka saar haraaga adag adiga oo si tartiib ah u taabanaya. Kaydka adag, kuleyl ilaa 500C si aad oksidize organics, ka dibna cadaydo dambaska. Ku kaydi armaajo qallalan, oo aan boodh lahayn—waligaa ha rarin weel la'aan iyada oo aan lahayn suuf ilaalin ah.

6. Goorta la Beddelayo Culfiifkaaga

Beddel silikoon carbide crucible haddii aad aragto:

• Dildilaaca qoto dheer ama qallafsanaanta qaabdhismeedka
• Darbiyada dhuuban ee muhiimka ah
• Wasakhowga joogtada ah ee saameeya tayada dhalaalka

Ha isku dayin inaad balastar ama dayactirto-ma istaahisho khatarta ah inaad fashilanto inta lagu jiro hawlgalka.

7. Alaabta Silicon Carbide ee laxidhiidha laga yaabaa inaad la kulanto

Iyadoo diiradda la saarayo crucibles, waxaa waxtar leh in la ogaado in silikoon carbide ka muuqataa noocyo badan oo warshadaha. Kuwaas waxaa ka mid ah baloogyada silikoon carbide tile blocks oo loogu talagalay dahaarka foornada, tiirarka dhoobada silikoon carbide ee qaab dhismeedka taageerada, iyo nambarada gubanaya silikoon carbide ee nidaamyada gubashada heerkulka sare. Waxa kale oo aad ka heli doontaa leben silikoon carbide, tuubooyinka (sida silikoon carbide tuubooyinka ilaalinta thermocouple), iyo xataa alaabta macaamiisha sida silikon carbide dhoobada dubista suxuunta ama cashada-in kasta oo kuwani waa kala duwanaansho hoose-cufnaanta aan ku habboonayn isticmaalka shaybaarka ama aasaaska.

Fiiro gaar ah: Alaabooyinka sida silikoon carbide ceramic plates casho ama saxanka dubista silikoon carbide Staub waxaa loo suuq geeyaa isticmaalka jikada oo ay ka maqan tahay nadiifnimada iyo cufnaanta lakabyada heerka warshadaha. Sidoo kale, qasabadaha saxanka dhoobada ee silicon carbide ama saxannada shiidadu waxay u adeegaan gabi ahaanba hawlo kala duwan oo ku saabsan tuubooyinka ama abrasives.

8. Gunaanad

Qalab silikoon carbide ah oo si wanaagsan loo dayactiray waxay socon kartaa boqolaal dhalaalid ah, kaa badbaadinaya waqti iyo lacag. Adigoo raacaya borotokoolka kulaylka saxda ah, iska ilaalinta shoogga kulaylka, oo u kaydinaysa si sax ah, waxaad heli doontaa waxqabadka ugu sarreeya dhoobadan waxqabadka sare leh. Iyo caqabadaha hadda jira ee alaabada ceyriinka ah, kordhinta nolosha curyaankaaga maahan mid caqli badan - waa lama huraan.
