Kufotokozera Kwachidule

Alumina Bubble amapangidwa ndi kusakaniza mwapadera chiyero chapamwamba cha alumina. Ndizovuta koma zosasunthika kwambiri potengera mphamvu zake. Kuwira kwa aluminiyamu kumagwiritsidwa ntchito popanga ma refractories opepuka omwe amatenthetsa matenthedwe pomwe matenthedwe otsika komanso kutentha kwambiri ndizofunikira kwambiri. Amagwiritsidwanso ntchito moyenera kwa loose-fill refractories.

Kugwiritsa ntchito		Zotsutsa

Alumina Bubble amagwiritsidwa ntchito popanga ma refr opepuka otsekereza ma refr ractories pomwe matenthedwe otsika komanso kutentha kwambiri ndizofunikira kwambiri komanso zoletsa zodzaza. Itha kugwiritsidwa ntchito popanga manja kapena zipolopolo zotchingira zambiri za ceramic poponya ndalama. Itha kugwiritsidwanso ntchito ngati bedi powombera mawilo akupera a vitrified komanso ngati media yosefera zakumwa zaukali kapena kusungunuka.

Bubble Alumina imapangidwa kuchokera ku alumina yoyera kwambiri mu ng'anjo yamagetsi yamagetsi. Akasungunuka, aluminiyamuyo amadzazidwa ndi mpweya woponderezedwa, womwe umatulutsa tizigawo tomwe timazungulira. Malo osungunuka a Bubble Alumina ndi pafupifupi 2100ºC.

Njira Yopanga Ndi Kugwiritsa Ntchito

Fused Bubble Alumina amapangidwa ndi kuwomba kusungunuka kwa chiyero chapamwamba cha Bayer process alumina mumlengalenga wowongolera kuti apange mabwalo opanda kanthu. Chifukwa cha kachulukidwe ake otsika ndi otsika kwambiri matenthedwe madutsidwe kadulidwe aluminiyamu kuwira ndi abwino mkulu aluminiyamu zochokera Insulating njerwa ndi castables.
