Alumina Bubble inogadzirwa nekusanganisa yakakosha yakakwira kuchena alumina. Iyo yakaoma asi yakanyanya friable maererano nekusimba kwayo. Alumina bubble rinoshandiswa mukugadzira lightweight insulating refractories uko yakaderera thermal conductivity uye yakakwirira tembiricha pro perties ndizvo zvinonyanya kudiwa. Inoshandiswawo zvinobudirira kune loose-fill refractories.
Alumina Bubble inoshandiswa mukugadzira lightweight insulating refr ractories uko yakaderera thermal conductivity uye yakakwirira tembiricha zvivakwa ndizvo zvinonyanya kudiwa pamwe neakasununguka kuzadza refractories. Iyo C inogona kushandiswa kugadzira maoko kana yakakwira insulating ceramic shells yekukanda mari. Inogona zvakare kushandiswa semubhedha mukupfurwa kwevitrified achikuya mavhiri uye se media yekusefa zvinwiwa zvine hukasha kana kunyungudika.
Bubble Alumina inogadzirwa kubva kumusoro-kuchena alumina mune yemagetsi arc vira. Kana yanyungudutswa, iyo alumina inoshongedzwa nemhepo yakamanikidzwa, iyo inoburitsa mativi maburi. Iyo yekunyunguduka kweBubble Alumina ingangoita 2100ºC.
Maitiro Ekugadzira uye Kushandisa
Fused Bubble Alumina inogadzirwa nekufuridza kunyungudika kwehutsanana hwepamusoro Bayer process alumina mumhepo inodzorwa kuti ibudise nzvimbo dzisina mhango. Nekuda kwekudzikira kwayo uye yakanyanya kudzika yekupisa conductivity yakasanganiswa alumina bubble yakanakira yakakwira alumina based Insulating Bricks uye castables.
