Isitini somlilo esinamabhamuza e-alumina siwuhlobo olusha lwezinto zokufudumeza ezishisayo futhi ezenziwe nge-alumina yezimboni esithandweni sikagesi ngokuncibilika nokufutha. Ifomu lekristalu lesitini se-alumina bubble refractory yi-a-Al2O3 microcrystal futhi umzimba oyinhloko yibhamuza le-alumina elingenziwa libe zonke izinhlobo zemikhiqizo enobumo obuhlukahlukene ukuze kusetshenziswe izinga lokushisa eliphakeme kakhulu elingu-1800℃ elinamandla amakhulu emishini kanye nokuminyana kwenqwaba ephansi.
I-Aluminium bubblle firebrick isebenzisa ibhola le-alumina bubble njengezinto zokusetshenziswa eziyinhloko, ukusebenza okuphezulu kwe-ultrafine powder njenge-annexing agent kanye ne-organic substance njenge-ejenti ebophayo ngokubunjwa nokomiswa, bese ixoshwa kuhhavini yokushisa ephezulu.
Isitini somlilo se-aluminium bubblle sinezici zokushisa ukushisa kanye ne-conductivity ephansi yokushisa, okungabangela umphumela omkhulu wokushisa ukushisa, ukunciphisa ukushisa kokushisa nokuthuthukisa ukusebenza kahle kokushisa. kusetshenziswa isitini se-aluminium bubblle refractory kungonga amandla aphezulu afika ku-30%. futhi izinga lokushisa lesevisi ye-alumina bubble block liphezulu lifika ku-1750 ℃. ukuzinza kokushisa kuhle futhi izinga lokushintsha komugqa wokushisisa liphansi, i-aluminium bubble block ingaholela impilo ende yesevisi.

Isitini se-alumina bubble siwuhlobo lwezinto eziphikisayo ezibaluleke kakhulu zokumelana nokushisa okuphezulu kanye nezidingo ezikhethekile zezikhundla zesithando somlilo kanye nomlilo, esetshenziswa kakhulu njengezitini zokuvikela ungqimba lwesithando somlilo nomlilo, kanye nezitini ze-aluminium bubble zingasetshenziselwa inkonzo. ama-linings ekukhiqizeni i-quartz ehlanzekile kakhulu embonini ye-electronics efana ne-ceramic tile linings kuma-turbines wegesi kanye nama-backup linings kuma-reactors.
Imboni ye-RS refractory njengomkhiqizi wezitini ze-alumina bubble ochwepheshe e-china, inezinzuzo eziningi zokuncintisana emakethe. uma unesidingo sezitini zebhamuza le-aluminium, noma unemibuzo nge-aluminium bubble firebrick mayelana nezinkomba ezibonakalayo namakhemikhali, sicela usithinte mahhala, sizokunikeza isitini se-aluminium refractory sekhwalithi ephezulu.
