Libakeng tsa indasteri moo mocheso o phahameng, khatello, le ho roala lisebelisoa tse thata, litharollo tse tšepahalang li bohlokoa.Litene tsa Sillimanitee hlahella e le "pere ea indasteri," e nang le thepa e ikhethang e matlafatsang ts'ebetso, e fokotsa litšenyehelo, le ho ntlafatsa boleng ba sehlahisoa ho pholletsa le metallurgy, ceramics le glass production. Ke ka hona e leng khetho e holimo lefatšeng ka bophara

1. Thepa ea mantlha: Ke eng e etsang hore litene tsa Sillimanite e be tsa bohlokoa?

E tsoa ho aluminosilicate mineral sillimanite, litene tsena li fana ka melemo e meraro e ke keng ea hlōloa:

Ultra-High Refractoriness:Ha li ntse li qhibiliha ka holimo ho 1800°C, li hanela mocheso o feteletseng (o bohlokoa bakeng sa ho qhibiliha ha tšepe le ho qhibiliha ha khalase, moo mocheso o fetang 1500°C) ntle le ho loana kapa ho theola seriti.

Katoloso e Tlase ea Thermal:Sekhahla se ka tlase ho 1% ho 1000 ° C se thibela ho phatloha ho tsoa ho ts'oenyeho ea mocheso, ho netefatsa hore ho tšoarella libakeng tse futhumatsang tse pholileng joalo ka libopi tse phatlohang.

Khanyetso e Phahameng:Li teteane ebile li thata, li mamella ho khoptjoa ke tšepe e qhibilihisitsoeng/slag le khoholeho ea lik'hemik'hale ho tsoa ho acid / alkalis - senotlolo sa ho lokisa lik'hemik'hale le metallurgy.

Litšobotsi tsena li fetola litene tsa sillimanite ho tloha ho "ntle-ho-ba" ho ea ho "ho tlameha ho ba le" bakeng sa ho ntlafatsa ts'ebetso.

2. Metallurgy: Ntlafatso ea tlhahiso ea tšepe le tšepe

Indasteri ea metallurgic e itšetlehile haholo ka litene tsa sillimanite bakeng sa lisebelisoa tse hatelitsoeng ke mocheso:

Blast Furnace Linings:Ho kenya "sebaka se chesang" (1500-1600 ° C) ea libopi tse hlahisang tšepe, li feta litene tsa khale tsa mollo. Setsi sa tšepe sa India se bone nako e telele ea ho phela ha sebōpi ka 30% le litšenyehelo tse tlase tsa 25% ka mor'a ho e fetola.

Tundish & Ladle Linings:Ho fokotsa tšilafalo ea tšepe le ho lelefatsa bophelo ba lesela ka 40% (ho ea ka moetsi oa tšepe oa Europe), ba etsa bonnete ba hore tšepe e qhibilihisitsoeng e sebetsa hantle.

Lijana tsa Desulfurization:Ho hanyetsa ha bona ho slag e ruileng ea sebabole ho boloka botsitso, ho thusa ho fihlela litekanyetso tse tiileng tsa bohloeki ba tšepe

Bakeng sa li-metallurgists, litene tsa sillimanite ke letsete la leano la tlhahiso

3. Ceramics: Ho matlafatsa Tile, Sanitary Ware & Tekheniki Ceramics

Ka li-ceramics, litene tsa sillimanite li sebetsa likarolo tse peli tsa bohlokoa:

Kiln Linings:Ho boloka mocheso o ts'oanang (ho fihlela ho 1200 ° C) ka libotlolong tsa ho chesa, katoloso ea bona e tlase e thibela tšenyo. Mohlahisi oa lithaele oa Chaena o ile a fokotsa likoloto tsa matla ka 10% ka mor'a ho khutlisa, ka 15-20% ea tšebeliso e tlaase ea matla ka kakaretso.

Raw Material Additive:E sila ka phofo (5-10% ka metsoako), e matlafatsa matla a mochine (25% e phahameng ea matla a flexural) le botsitso ba mocheso (ka tlase ho 30% ts'enyo ea mocheso oa mocheso) ka ceramic ceramics.

4. Tlhahiso ea Khalase: Ho leka-lekanya Boleng le Litšenyehelo.

Litene tsa Sillimanite li rarolla mathata a bohlokoa a tlhahiso ea likhalase:

Kiln Regenerators:Li-regenerator tse kenyang mocheso ka lesela, li hanela ho phatloha le ho kenella ha mouoane oa khalase. Moetsi oa Amerika Leboea o bone bophelo bo bolelele ba litene ka lilemo tse 2, a fokotsa litšenyehelo tsa ho nchafatsa ka $150,000 ka onto e ’ngoe le e ’ngoe.

Khalase e khethehileng:Ka tlas'a 0.5% iron oxide, ba qoba ho silafatsa likhalase tsa optical kapa borosilicate, ho netefatsa ho hlaka le botsitso ba lik'hemik'hale bakeng sa li-skrini tsa labware kapa li-smartphone.

5. Lik'hemik'hale le Liindasteri tse ling: Ho sebetsana le maemo a thata

Chemical Processing:Ha li kenya li-reactors tse nang le mocheso o phahameng, li thibela ho lutla le ho lelefatsa bophelo ba thepa—e leng habohlokoa bakeng sa tšireletseho tlhahisong ea manyolo, ea petrochemical kapa ea meriana.

Ho Chesoa ha Litšila:Ho hanyetsa mocheso oa 1200 ° C le ho senya litšila, li fokotsa tlhokomelo ea limela tse senyang matla.

Khetha litene tsa Sillimanite bakeng sa Katleho ea Nako e telele

Hore na o moetsi oa tšepe, moetsi oa ceramic, kapa moetsi oa likhalase, litene tsa sillimanite li fana ka sephetho. Motsoako oa bona o ikhethang oa ho hanyetsa, katoloso e tlase, le ho hanyetsa li etsa hore e be tharollo e sa bitseng chelete e ngata, e sebetsanang le maemo a mangata.

Na u ikemiselitse ho ntlafatsa? Ikopanye le sehlopha sa rona bakeng sa qotso e ikhethileng le tšehetso ea tekheniki. Ha re aheng bokamoso bo atlehileng ba indasteri—hammoho.
