Alaabooyinka Iska caabinta kulaylka Sare
010203
Corundum Bricks-Hengli
Astaamaha
Lebenka Corundum, oo sidoo kale loo yaqaan lebenka alumina, waa aluminium-alaabooyin sare-u-qaadis leh oo leh dhowr astaamood oo muhiim ah:
1. ** daahir sare: **Caadi ahaan ka kooban in ka badan 90% alumina (Al2O3), hubinta sifooyinka dib-u-celinta ee ugu fiican
2. ** Caabbinta Heerkulka Sare: **Awood u leh inay u adkeyso heerkulka ilaa 1900 ° C, taasoo ka dhigaysa inay ku habboon yihiin jawiga heerkulka sare ee ugu baahida badan.
3. **Awoodda Makaanikada: **Lebenka Corundum waxay leeyihiin awood cadaadis sare leh iyo iska caabin wanaagsan oo xidhidh, taas oo u sahlaysa inay xakameyaan culaysyo culus iyo xaalado xoqan.
4. ** Caabbinta Daxalka: **Waxay iska caabiyaan daxalka ka yimaadda aashitada, alkalis, iyo kiimikooyinka kale, iyaga oo cimrigooda ku kordhinaya degaano adag.
5. **Porosity Hoose: **Porosity-hooseeya waxay ka caawisaa ka hortagga qulqulka walxaha dhalaalay iyo gaasaska, kor u qaadida adkeysiga iyo sifooyinka kuleylka kuleylka.
6. **Xasilloonida kulaylka: **Waxay soo bandhigaan degganaansho heerkul sare ah iyo iska caabin shoog kulayl ah, taas oo muhiim u ah hababka ku lug leh isbeddellada heerkulka degdegga ah.
7. ** Xasilooni Dhinaceed: **Waxyaabaha aluminiumka ah ee sarreeya waxay hubisaa in lebenku ay ilaalinayaan qaabkooda iyo mugga heerkulka sare, ka hortagga fashilka qaabdhismeedka.
Astaamahan ayaa ka dhigaya lebenka corundum ku habboon in loo isticmaalo codsiyada heerkul sare ee kala duwan, oo ay ku jiraan foornooyinka qaraxa, shooladaha qaraxa kulul, biraha birta ah, iyo foornooyinka kale ee warshadaha iyo kilns.
Codsiga caadiga ah
Si ballaaran loo isticmaalo warshadaha sida bacriminta, ceramics electro, petrochemical, steel, foundry, steel alloy, refractories, iwm Codsiga caadiga ah sida reformer sare iyo matoor gaaska dahaarka, taageero sariirta kicinta, foornada induction channel, dib u kululaynta foornada foornada, iwm.
