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

1. Hordhac

Kaliya 24 saacadood ka hor, xarun weyn oo Ohio ah ayaa soo warisay 30% korodhka wakhtiga foornada taas oo ay ugu wacan tahay fashilka degdega ah ee jilbaha - qaar badan ayaa dib loo raacay si aan habboonayn. silicon crucibles carbide. Tani waxay muujinaysaa arrin baahsan laakiin la hagaajin karo ee hawlgallada dhalaalidda biraha ee warshadaha iyo hiwaayadda leh. Haddi aad aluminium ku tuurayso aqoon-is-weydaarsiga dambe ama aad ku shaqaynayso aasaaska mugga sare, ogaanshaha sida habboon ee loo isticmaalo iyo daryeelka crucible-ga silikoon carbide waa lama huraan.

Silicon carbide crucibles waxaa lagu qiimeeyaa kuleylkooda gaarka ah, caabbinta shoogga kulaylka, iyo awoodda u adkeysiga heerkulka ka sarreeya 1,600 ° C. Laakiin xitaa qaybaha dhoobada silikoon carbide-ka ugu fiican-sida silikoon carbide dhoobada dhoobada, silikoon carbide gubi nozzles, ama blocks silikoon carbide tile blocks-waxay u baahan yihiin isticmaalka saxda ah si loo bixiyo qiimaha muddada dheer.

2. Fahamka Crucible-kaaga Silicon-Carbide

Kahor intaadan quusin isticmaalka, waxaa muhiim ah in la aqoonsado waxa dejinaya silicon carbide kala duwan. Si ka duwan sida dhoobada-graphite crucibles dhaqameed, silikoon carbide waxay bixisaa iska caabin oksaydhyo sare iyo xoog farsamo. Si kastaba ha ahaatee, waxaa badanaa lagu wareersan yahay dhoobada sare ee la midka ah.

Tusaale ahaan, boron carbide vs Silicon carbide: halka boron carbide uu adag yahay oo loo isticmaalo codsiyada hubka, aad bay u qaalisan tahay oo aad bay u yar tahay kulaylka- samaynta silikoon carbide go-to-ka-Crucibles. Sidoo kale, alaabta dhoobada ee silikoon nitride-sida silikoon nitride walxo warshadaysan, silikoon nitride giraanti, ama gaashaanka kulaylka silikoon nitride-waxay aad ugu fiican yihiin baaskiil wadida kulaylka badan laakiin caadi ahaan waa ka qaalisan yihiin oo way ka yar yihiin hawlgallada dhalaalka caadiga ah.

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

3.1. Kuleylinta Kahortagga

Waligaa hargab ha dhigin Silicon carbide crucible si toos ah foorno kulul. Shoogga kulaylku wuxuu sababi karaa dildilaacyo. Taa beddelkeeda, dhig foorno qabow oo si tartiib tartiib ah kor ugu qaad heerkulka ilaa 1-2 saacadood ilaa 200-300 ° C si aad uga saarto qoyaanka. Ka dib, si tartiib ah ugu kordhi heerkulka shaqadaada.

3.2. Soo rarista iyo dhalaalidda

Isticmaal qalab lacag qaadasho oo qallalan oo nadiif ah. Biraha qoyan ama wasakhaysan waxay keeni karaan qarax uumi ama falcelin kiimikaad oo hoos u dhiga xuubka xuubka ah. Iska ilaali buuxinta-ka tag ugu yaraan 20% meel sare si aad uga hortagto daadad inta lagu jiro dhalaalidda.

3.3. Wax ka qabashada iyo shubidda

Had iyo jeer isticmaal suumanka ku habboon ee loogu talagalay qaabka iyo cabbirka sariirahaaga. Saamaynta lama filaanka ah ama u janjeera si xoog leh waxay dildillaci kartaa xitaa tiirarka dhoobada ee carbide silikoon adag ama siddo. Si habsami leh ugu shub oo iska ilaali inaad xoqdo ku xoqdo derbiyada foornada ama caaryada.

4. Nadiifinta iyo Dayactirka

Isticmaalka ka dib, u ogolow in weelku uu si dabiici ah ugu qaboojiyo gudaha foornada haddii ay suurtogal tahay. Qaboojinta degdega ah ee hawada ama biyaha ayaa si aad ah u gaabinaysa nolosheeda. Marka la qaboojiyo, ka saar boodhka ama hadhaaga buraash jilicsan ama xoqad alwaax ah - waligaa ha isticmaalin qalabka birta ah ee kor u qaadi kara dusha sare.

Haddii dhismuhu sii socdo, nadiifinta kulaylka khafiifka ah (dib ugu kululaynta 800°C ee jawi oksaydhaysan) ayaa gubi kara hadhaaga. Ka fogow nadiifiyeyaasha kiimikada ilaa si gaar ah loogu oggolaado suxuunta dhoobada silikoon carbide ama qaybaha warshadaha.

5. Dhibaatooyinka guud iyo xalalka

5.1. Dilaac ama dildilaac

Sababta: shoog kulaylka ama saamaynta farsamada. Xalka: Had iyo jeer si tartiib tartiib ah u kulayl oo si taxadar leh ula qabso.

5.2. Cimriga oo yaraatay

Sababta: Isticmaalka biraha aan isqaban karin (tusaale, alwaaxyada rasaasta sare) ama oksaydheynta xad dhaafka ah. Xalka: Ku dhig darajada qolofka ah nooca birta ah oo xaddid soo-gaadhista hawada heerkulka ugu sarreeya.

5.3. Jahwareer ku Yimid Ceramics Kale

Isticmaalayaal badan ayaa si qalad ah u qaadanaya in dhammaan ceramics-ka madow ay isku mid yihiin. Ogsoonow in suxuunta dubista dhoobada silikoon carbide, taarikada cashada silikoon carbide dhoobada, ama xitaa silikoon carbide dhoobada u adeegta maddiibado-iyado laga sameeyay isla maaddooyinka aasaasiga ah-waxaa loo qaabeeyey si ka duwan kuwa warshadaha. Sidoo kale, tuubooyinka dhoobada silikoon carbide, tuubooyinka silikoon carbide, ama tuubooyinka ilaalinta heerkulbeegga silikoon carbide waxay u adeegaan ujeeddooyin kala duwan mana aha in la beddelo.

6. Goorta la Beddelayo Culfiifkaaga

Hubi qashinka silikoon carbide ka hor isticmaal kasta. Beddel haddii aad dareento:

• Dildilaaca qoto dheer ama godadka
• Dhumuc weyn oo gidaarka ah (in ka badan 20% khasaare)
• glazing ama barar dusha gudaha ah

Isticmaalka weel burburay waxay halis gelinaysaa birta, burburka foornada, ama khataraha badbaadada.

7. Gunaanad

Qalab silikoon carbide crucible waa qalab wax qabad sare leh kaas oo keena waxtar aan la qiyaasi karin - haddii si sax ah loola dhaqmo. Adigoo raacaya kuleyliyaha saxda ah, maaraynta, iyo borotokoolka nadiifinta, waxaad kordhin doontaa cimrigeeda oo waxaad xaqiijin doontaa natiijooyin joogto ah. Iyo in kasta oo alaabada ay ka midka yihiin suxuunta dhoobada dhoobada ah ee silikoon carbide ama silikoon carbide ceramic ramekins ay wadaagaan dhaxal isku mid ah, xusuusnow in qaybaha heerka-warshadaha sida leben carbide silikoon ama rbsic silikoon carbide tile blocks loo farsameeyay gabi ahaanba baahiyo kala duwan. Si xushmad leh ula dhaqan saxaradaada, waxayna kuugu adeegi doontaa si la isku halleyn karo iyada oo loo marayo boqolaal dhalaal ah.
