Irbad-U eg Kiristaalo Mullite ah Kaas oo Siinaya Bar dhalaalaysa Sare, Balaadhinta kulaylka Hoose ee La beddeli karo iyo iska caabin heer sare ah oo loogu talagalay shoogga kulaylka

Corundum mullite
Nadiifin sare oo isku dhafan mullite
Mulley-ku-daran koronto

Sharaxaad Gaaban

Fused Mullite waxa soo saara habka Bayer alumina iyo ciid quartz nadiif ah oo sarreeya iyada oo ku dhex milmay foornada koronto ee aadka u weyn.

Waxay leedahay maaddo sare oo ah kiristaalo mullite oo kale ah oo irbad u eg taasoo bixisa dhibic dhalaalaysa, balaadhinta kulaylka oo hooseeya iyo iska caabin heer sare ah oo shoogga kulaylka ah, qallafsanaanta culeyska, iyo daxalka kiimikada heerkulka sare.

Habka Waxsoosaarka

Fused Mullite waxa soo saara habka Bayer alumina iyo ciid quartz nadiif ah oo sarreeya iyada oo ku dhex milmay foornada koronto ee aadka u weyn.

Codsiga

Waxaa si weyn loo isticmaalaa sida alaabta ceeriin ee refractories fasalka sare, sida leben dahaarka ee foornada dhalada ah iyo leben loo isticmaalo in foornada dabayl kulul ee warshadaha birta.

Waxa kale oo loo isticmaalaa foornada dhoobada iyo warshadaha petrochemical iyo codsiyo kale oo badan.

Ganaaxyada Fused Mullite waxaa loo isticmaalaa daaha Aasaaska ee caabbinta shoogga kulaylka iyo sifooyinka aan qoyanayn

Astaamaha

• Degganaanshaha kulaylka sare
• Balaadhinta kulaylka oo hooseeya
• Iska caabbinta weerar-ku-ool heer-kulka sare
• Halabuurka kiimikada deggan

Mullite, nooc kasta oo macdan naadir ah oo ka kooban aluminium silicate (3Al2O3 · 2SiO2). Waxa la sameeyay marka la shido alaabta ceeriin ee aluminosilicate waana waxa ugu muhiimsan ee ka kooban alaabada cad cad ee dhoobada ah, pocelains, iyo kuwa heerkulka sare leh ee dahaadhida iyo walxaha refractory. Waxyaabaha ay ka kooban tahay, sida mullite, haysashada saamiga alumina-silica ee ugu yaraan 3:2 kama dhalaali doonto ka hooseeya 1,810 ° C (3,290 ° F), halka kuwa saamiga hoose leh ay qayb ahaan dhalaali doonaan heerkul hooseeya 1,545 ° C (2,813 ° F). F)

Mulley dabiici ah ayaa laga helay sida cad, kiristaalo dhaadheer oo ku yaal Island of Mull, Hebrides Inner, Scot. Waxa lagu aqoonsaday oo keliya meelaha isku-dhafka ah ee argillaceous (cyey) ee dhagxaanta igneous-ka ah, xaalad soo jeedinaysa heerkul aad u sarreeya samaynta.

Marka laga soo tago muhiimada ay u leedahay dhoobada caadiga ah, mullite waxa ay noqotay doorasho shay oo loogu talagalay dhoobada qaab dhismeedka horumarsan iyo kuwa shaqaynaya sababtoo ah sifooyinkeeda wanaagsan. Qaar ka mid ah sifooyinka cajiibka ah ee mullite waa balaadhinta kulaylka hooseeya, kulaylka kuleylka hooseeya, caabbinta gurguurta oo aad u wanaagsan, xoog heerkul sare ah, iyo xasilooni kiimikaad oo wanaagsan. Habka samaynta mullittu waxay ku xidhan tahay habka la isku darayo falceliyeyaasha alumina-iyo silica-ka kooban. Waxa kale oo ay la xidhiidha heerkulka kaas oo fal-celintu u horseeddo samaynta mullitiga (heerkulka mullitisation). Heerkulka kala-baxa ayaa la sheegay inuu kala duwan yahay ilaa dhowr boqol oo darajo Celsius iyadoo ku xiran habka isku-dhafka ah ee la isticmaalay.
