Uyini umehluko phakathi kwezitini eziphakeme ze-alumina refractory kanye isitini sobumba esakhiwe?

1. Inani lamakhemikhali le-PH lezitini eziphakeme ze-alumina ezikhanyisayo lingezitini ezingathathi hlangothi nezine-alikhali, futhi izitini zobumba ezikhombisayo zingezitini ezingathathi hlangothi nezine-asidi.

2. Ngaphezu kokumelana nokushaqeka okushisayo kwezitini eziphakeme ze-alumina ezikhanyisayo, ezinye izitini eziphikisayo azilingani nezitini ezenziwa ngobumba. Ngokuvamile, ekwakheni ama-kilns neminye imishini eshisayo, uma kungasetshenziswa izitini ezakhiwe ngobumba, kusetshenziswa izitini eziphakeme ze-alumina ekwakhiweni kwamatshe.

3. Izitini eziphikisayo ze-alumina eziphakeme ziyizitini ze-aluminium silicate ezikhanyisayo ezinokuqukethwe kwe-Al2O3 okukhulu kuno-48%. Izitini ezikhonjiwayo zobumba zibhekisa kwimikhiqizo yobumba enokuqukethwe kwe-Al2O3 kokungu-30% -40% kwe-aluminium silicate materials.

4. Izitini zobumba zinomsebenzi omuhle wokushisa futhi ziyamelana nokushisa okusheshayo nokubanda okusheshayo; izinga lokushisa lokudubula lezitini eziphakeme ze-alumina ezikhanyelayo lincike ekusebenzeni kokuhlwaya kwezinto zokusetshenziswa ze-bauxite.

5. Ukushisa okuthambile kwezitini eziphakeme ze-alumina ezikhanyayo kuyahluka ngokuqukethwe kwe-Al2O3. Izitini ezikhombayo zobumba zinamazinga okushisa asezingeni eliphansi okuthambisa, ancipha emazingeni okushisa aphezulu, futhi abe nokushisa okushisayo okungu-15% -20% okuphansi kunezitini ze-silica.
