Kodi pali kusiyana kotani pakati pa alumina high refractory njerwa ndi njerwa zoyikapo dothi?

1. Mtengo wa mankhwala a PH wa njerwa zapamwamba zopangira alumina ndi wa njerwa zosaloŵerera ndi zamchere, ndipo njerwa zadothi ndi za njerwa zosalowerera.

2. Kuphatikiza pa kukana kwamphamvu kwamatayala okwera a alumina okwera, njerwa zina zotsitsimula sizabwino ngati njerwa zadothi. Nthawi zambiri, pomanga ma kilns ndi zida zina zotentha, ngati njerwa zadothi zitha kugwiritsidwa ntchito, njerwa zapamwamba za alumina zimagwiritsidwa ntchito pomanga.

3. Njerwa za aluminiyamu zapamwamba ndizopanga njerwa za Aluminium zopitilira 2%. Njerwa zosanja zimayang’ana zinthu zadothi zomwe zili ndi Al3O48 zomwe zili ndi 2% -3% yama aluminiyamu.

4. Njerwa zadothi zimakhala ndi matenthedwe abwino ndipo sizimagwira kuzizira komanso kutentha kwachangu; kutentha kotentha kwa alumina njerwa refractory kumatengera sintering ntchito ya zipangizo za bauxite.

5. Kutentha kofewa kwa njerwa zapamwamba zopangira aluminiyamu kumasiyana ndi zomwe zili Al2O3. Njerwa zokhazikitsira pansi zimakhala ndi kutentha kotsika pang’ono, zimachepa kutentha kwambiri, ndipo zimakhala ndi matenthedwe okwera 15% -20% poyerekeza ndi njerwa za silika.
