Corundum Bricks-Hengli
Likaroloana
Litene tsa Corundum, tse tsejoang hape e le litene tsa alumina, ke lihlahisoa tse hanyetsanang tsa aluminium tse nang le likarolo tse 'maloa tsa bohlokoa:
1. **Bohloeki bo Phahameng: **Ka tloaelo e entsoe ka alumina e fetang 90% (Al2O3), e netefatsang thepa e ntle ea refractory.
2. **Ho hanyetsa Mocheso o Phahameng: **E khona ho mamella mocheso ho fihlela ho 1900 ° C, e etsa hore e tšoanele libaka tse batloang haholo tsa mocheso o phahameng.
3. **Matla a Mechini: **Litene tsa Corundum li na le matla a phahameng a ho hatella le ho hanyetsa ho apara hantle, ho li nolofalletsa ho sebetsana le meroalo e boima le maemo a hlabang.
4. **Corrosion Resistance: **Li hanela ho bola ha li-slags, acid, alkalis le lik'hemik'hale tse ling, 'me li lelefatsa bophelo ba tsona libakeng tse thata.
5. **Porosity e tlase: **Porosity e tlaase e thusa ho thibela ho kenngoa ha thepa le likhase tse qhibilihisitsoeng, ho matlafatsa nako e telele le thepa ea ho kenya mocheso.
6. **Thermal Stability: **Li bonts'a botsitso bo botle ba mocheso le ho hanyetsa mocheso oa mocheso, o bohlokoa bakeng sa lits'ebetso tse amanang le liphetoho tse potlakileng tsa mocheso.
7. **Botsitso ba Dimensional: **Likahare tse phahameng tsa alumina li tiisa hore litene li boloka sebōpeho le molumo oa tsona mocheso o phahameng, ho thibela ho hlōleha ha moralo.
Likarolo tsena li etsa hore litene tsa corundum li be tse loketseng ho sebelisoa lits'ebetsong tse fapaneng tsa mocheso o phahameng, ho kenyeletsoa libopi tse phatlohileng, litofo tse chesang, litepisi tsa tšepe le libopi tse ling tsa indasteri.

E sebelisoa haholo liindastering tse kang manyolo, li-ceramics tsa motlakase, petrochemical, tšepe, foundry, alloy steel, refractories, joalo-joalo. Kopo e tloaelehileng e kang reformer ea bobeli le lesela la jenereithara ea khase, ts'ehetso ea bethe ea catalyst, sebōpi sa ho kenya mochine, ho futhumatsa mollo oa sebōpi, joalo-joalo.
