Alumina npuas yog tsim los ntawm fusing tshwj xeeb siab purity alumina.Th e yaj yog atomized nrog compressed cua uas ua rau lub hollow sphere. Nws yog ib qho nyuaj tab sis tsis tshua muaj friable nrog kev hwm rau nws lub zog siab th. Alumina npuas yog siv nyob rau hauv zus tau tej cov khaub-ncaws nyias insulating refractories uas tsis muaj thermal conductivity thiab siab kub pro perties yog cov tseem ceeb yuav tsum tau. Nws kuj tseem siv tau zoo rau xoob-fill refractories.
Alumina Bubble yog siv rau hauv kev tsim cov khoom siv hluav taws xob sib sib zog nqus refr ractories uas tsis tshua muaj thermal conductivity thiab cov khoom kub kub yog qhov tseem ceeb raws li cov khoom siv xoob xoob. Nws C tuaj yeem siv rau lub tes tsho tsim los yog siab insulating ceramic plhaub rau peev casting. Nws kuj tseem siv tau los ua ib lub txaj hauv cov txheej txheem tua hluav taws ntawm cov vitrified sib tsoo lub log thiab ua ib qho kev tshaj tawm los lim cov kua dej los yog melts.
Bubble Alumina yog tsim los ntawm high-purity alumina nyob rau hauv ib tug hluav taws xob arc rauv. Thaum melted, lub alumina yog atomized nrog compressed cua, uas ua hollow spheres. Lub melting point ntawm Bubble Alumina yog kwv yees li 2100ºC.
Txheej Txheem Ntau Lawm Thiab Thov
Fused Bubble Alumina yog tsim los ntawm tshuab cov yaj ntawm siab purity Bayer txheej txheem alumina nyob rau hauv ib qho chaw tswj los tsim hollow spheres. Vim tias nws qhov qis qis thiab tsis tshua muaj cua sov condal zoo fused alumina npuas yog qhov zoo rau cov qib siab zoo nkauj thiab cov khoom siv ua kom yooj yim.
