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

1. Hordhac

Kaliya 24 saacadood ka hor, shir cilmiyeedka agabka weyn ee Jarmalka ayaa muujiyay baahida sii kordheysa ee ceramics-ka-gaar ahaan silsiladda carbide crucibles-labadaba qaybaha macdanta iyo tamarta nadiifka ah. Iyada oo ay warshaduhu u riixayaan waxyaabo waxtar leh, waara, iyo kulayl ahaan deggan, ogaanshaha sida saxda ah ee loo isticmaalo crucible carbide silicon waligeed ka muhiimsan ma noqon.

Haddi aad ku dhalaalayso biraha meel qadiimiga ah, samaynta tijaabooyinka shaybaadhka, ama sahaminta dhoobada heerkul sare, si xun u maamulida qalabkan muhiimka ah waxay u horseedi kartaa dildilaacyo, faddarayn, ama xataa guul daro musiibo ah. Hagahan waxa uu ku siinayaa tillaabooyin cad oo la fulin karo si aad sida ugu fiican uga faa'iidaysato silsiladda carbide crucible-oo iska ilaali god-xumada caadiga ah.

2. Waa maxay Silikon Kaarbide Crucible?

A Silicon carbide crucible waa weel heerkulkiisu sarreeyo oo laga sameeyay silikoon carbide-ka dhisme caan ku ah engegnaanta xad dhaafka ah, kulaylka, iyo iska caabinta shoogga kulaylka. Si ka duwan qolofleyda dhoobada-garaafiga ah ee dhaqameed, silikoon carbide crucibles waxay u adkeysan karaan heerkulka ka sarreeya 1600°C (2912°F) oo leh hoos u dhac yar.

Waxaa si weyn loogu isticmaalaa meelaha aasaaska ah, shaybaarrada, iyo xitaa meelaha niche ah codsiyada sida samaynta suxuunta dubista dhoobada silikoon carbide ama alaabta cashada ee silikoon carbide dhoobada. Alaabooyinka la xidhiidha waxaa ka mid ah silikoon carbide dhoobada dhoobada, silikoon carbide giraangiraha, iyo xataa silikoon carbide gubi nozzles-dhammaan ka faa'iidaysanaya sifooyinka walxaha adag.

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

3.1. Kormeer Kahor Isticmaalka Koowaad

Had iyo jeer hubi silikoonkaaga cusub kaarbiid crucible dildilaaca timaha, jajabka, ama cilladaha dusha sare. Xataa dhaawaca yar ayaa ka sii dari kara cadaadiska kulaylka. Isbarbar dhig qaybaha kale ee nadiifka ah sida silikoon nitride dhoobada dhoobada ama rbsic silicon carbide tile blocks - arrimaha tayada.

3.2. Si tartiib ah u qalaji oo si tartiib ah u kulayl

Waligaa si toos ah ha u dhigin qolof qabow foorno kulul. Qoyaanka ku xayiran daloolada micnaha yar ayaa ku soo qulquli kara uumiga oo sababi kara jab. Halkii:

• Ku rid weelka foornada heerkulka qolka.
• Si tartiib ah kor ugu qaad heerkulka: 100-150 ° C saacaddii ilaa laga gaaro 600 ° C.
• Ku hay 600 ° C 1-2 saacadood si aad si buuxda u engejiso.
• Kadib tartiib tartiib ugu kordhi heerkulka shaqadaada.

Habkan, oo loo yaqaan 'daaweynta', ayaa si la mid ah muhiim ugu ah tuubooyinka dhoobada silikoon carbide ama tuubooyinka ilaalinta heerkulbeegga silikoon carbide.

3.3. Ka fogow shoogga kulaylka xilliga isticmaalka

Marka la kululeeyo, iska ilaali isbeddelada heerkulka degdega ah. Ha ku darin bir qabow qolof kulul oo guduudan. Horey u kululee alaabtaada kharashka haddii ay suurtogal tahay. Sidoo kale, waligaa ha damin weel kulul oo biyo ah—tani waxay si siman u khusaysaa suxuunta foornada dhoobada silikoon carbide ama saxamada dhoobada silikoon carbide ee lagu isticmaalo jikooyinka.

3.4. Isticmaal Aaladaha Maareynta Habboon

Had iyo jeer kor u qaad oo ku shub adiga oo isticmaalaya suumanka ama wiishashyada qolofka ah ee loogu talagalay isticmaalka kulaylka sareeyo. Ku tuurista ama ku tumashada weelka ka dhanka ah gidaarada foornada waxay keeni kartaa jajabyo yaryar oo hadhow u horseeda fashil.

4. Dhibaatooyinka guud iyo xalalka

4.1. Dilaac ama dildilaac

Sababta: Kuleyl degdeg ah / qaboojin ama saameyn farsamo. Xalka: Raac borotokoollada kuleyliyaha saxda ah oo si taxadar leh u qabo.

4.2. Wasakhowga Birta

Sababta: Hadhaaga dhalaalkii hore ama alloys-ka aan ku habboonayn Xalka: Si fiican u nadiifi inta u dhaxaysa isticmaalka. Biraha falceliska ah, tixgeli inaad isticmaashid silikoon nitride crucible oo ka timid warshada caanka ah ee silikoon nitride crucible-waxay bixiyaan xitaa tamar-la'aan kiimikaad sare leh.

4.3. Cimriga oo yaraatay

Sababta: Kuleyl xad dhaaf ah oo ka baxsan xadka la qiimeeyay ama soo-gaadhista dharbaaxada daxalka ah. Xalka: Ku dhex shaqee tilmaamaha heerkulka soo-saareha kana fogow qulqulatooyinka gardarada leh haddii aan qoloftu si gaar ah iyaga loogu qiimayn.

5. Nadiifinta iyo Kaydinta

Isticmaalka ka dib, qaboojiyaha si dabiici ah ugu qabooji foornada ama looxa fiber dhoobada ah - waligaa ha dul saarin bir qabow. Marka la qaboojiyo, ka saar haraaga adag burush jilicsan ama xoqin aan bir ahayn. Ka fogow biyaha ilaa aan weelku si buuxda u qaboojin oo uu engegin ka hor isticmaalka dambe.

Ku kaydi meel qalalan oo aan boodh lahayn. Si taxadar leh u dheji-taarikada dhoobada ah ee silikon carbide ee cashada ama taarikada dhoobada madow ee silikoon carbide ayaa laga yaabaa inay jajabaan haddii si khaldan loo maamulo, oo isku mid ah ayaa ku socda qashinka warshadaha.

6. Goorta la Beddelayo Culfiifkaaga

Beddel silikoon carbide crucible haddii aad aragto:

• Dildilaaca qoto dheer ama godadka
• Dhumucda darbiga muhiimka ah
• Gariir ama qallafsanaan
• Arrimaha ku dheggan ee soo noqnoqda

Ha halis gelin dhalaalid ama burbur foornada. Bedelaadaha tayada sare leh ayaa la heli karaa iyadoo ay weheliso walxo dheeri ah sida silikoon carbide ceramik u adeegida maddiibado, silikoon carbide ceramic ramekins, ama xataa gaashaammada kulaylka silikoon nitride ee habaynta horumarsan.

7. Bonus: Silicon Carbide vs. Silicon Nitride

Iyadoo silikoon carbide uu ku fiican yahay kulaylka kulaylka iyo iska caabinta oksaydhka, silicon nitride waxay bixisaa adkaanta jabka sare iyo iska caabinta shoogga kulaylka ee deegaannada qaarkood. Codsiyada nadiifinta aadka u sarreeya, qaarkood waxay door bidaan silikoon nitride silikoon ama taarikada nitride silikoon. Doorashada u dhaxaysa boron carbide vs silicon carbide ama silicon nitride vs silicon carbide waxay kuxirantahay kuleylkaaga gaarka ah iyo baahidaada kiimikaad.

8. Gunaanad

Qalab silikoon carbide crucible waa qalab awood leh-laakin waa haddii si xushmad leh loola dhaqmo. Adigoo raacaya tillaabooyinkan kululaynta, maaraynta, nadiifinta, iyo kaydinta, waxaad kordhin doontaa cimrigeeda, waxaad hubin doontaa waxqabad joogto ah, kana fogaato shilalka qaaliga ah. Haddii aad ku jirto birta, cilmi-baarista, ama xitaa dhoobada farshaxanimada (ka fakar saxanka subagga dhoobada ee silicon carbide oo dabool leh ama alaabta cashada gacanta lagu sameeyo), daryeelka saxda ah ayaa ka dhigaya farqiga oo dhan.

Mareegahayaga oo la aasaasay Oktoobar 17, 2012, waa shirkad tignoolajiyadeed sare leh oo ay ka go'an tahay cilmi-baarista iyo horumarinta, wax soo saarka, farsamaynta, iibinta iyo adeegyada farsamada ee alaabta qaraabada dhoobada ah sida Sidee.
