Calcined Alumina Ultrafine Mo Fa'ato'aga Maualuga

O pa'u alumina fa'atosina e faia e ala i le fa'avasegaina sa'o o alumina alamanuia po'o le alumini hydroxide i le vevela talafeagai e fa'aliliu ai i le fa'amaua crystallineα-alumina, ona oloina lea i totonu o ni pauta laiti.E mafai ona fa'aogaina pa'u pa'u pa'u fa'ase'e i faitoto'a fa'ase'e, fa'aumu, ma piliki alumina.E le gata i lea, e mafai ona faʻaaogaina i castables ma silica fume ma reactive alumina powders, e faʻaitiitia ai le faʻaopoopoga o le vai, porosity ma faʻateleina le malosi, mautu voluma.

Alumina oloa ma ia calcined alumina paʻu e pei o mea mata e sili atu le malosi faʻainisinia, maualuga maaa, maualuga atu le resistivity eletise ma conductivity vevela lelei.O le calcined alumina micropowder e mafai ona faʻaaogaina lautele i mea faʻaeletoroni, faʻapipiʻi fausaga, refractories, abrasives, mea faʻalelei, et

Alumina calcined o alpha-aluminas o lo'o aofia ai ma fa'aputuga fa'aputu o tioata alumina ta'itasi.O le tele o nei tioata autu e faalagolago i le tikeri o le calcination ma le agglomerate tele i luga o laasaga olo mulimuli ane.O le tele o alumina calcined o loʻo tuʻuina atu i le eleele (<63μm) poʻo le eleele lelei (<45μm).O faʻaputuga e leʻo faʻaumatia atoa i le taimi o le oloina, o se eseesega tele mai alumina faʻafefe o loʻo faʻapipiʻiina atoa e ala i le faʻaogaina o le faʻagasologa.O alumina ua fa'avasegaina o lo'o fa'avasegaina e ala i mea o lo'o i totonu o le soda, lapopo'a ma le tikeri o le fa'ama'aina.O alumina fa'a'ele'ele ma eleele lelei e fa'aaogaina e fai ma fa'atumu matrix e fa'aleleia ai le fa'atinoga o le gaosiga o mea fa'apitoa e fa'atatau i mea fa'alenatura.

O alumina fa'atosina e iai le lapo'a e pei o minerale fa'aeleele ma e mafai ona faigofie ona suia fa'atasi i lalo ifo o le mama.E ala i le faʻateleina o le aofaʻi o le alumina o mea faʻafefiloi ma le faʻaleleia atili o latou faʻapipiʻi vaega e ala i le faʻaopoopoina o le alumina lelei, o le refractoriness ma mea faʻainisinia, e pei o le vevela modulus o le malepelepe ma le abrasion resistance, ua faʻaleleia.Ole manaoga ole vai ole alumina calcined e faʻamatalaina ile aofaʻi o agglomerates totoe ma le vaega o luga.O le mea lea, o alumina calcined ma le eleele maualalo e sili ona lelei e fai ma faʻatumu i piliki ma castables.Fa'apitoa alumina calcined i luga o le eria maualuga, e mafai ona sui le omea e pei o le plasticizer i fana ma ramming fefiloi.O oloa fa'amago fa'alelei ua fa'aleleia e nei oloa e fa'atumauina lelei uiga fa'apipi'i ae fa'aalia le fa'aitiitia o le fa'aitiitia pe a uma ona fa'agogo ma fana.

Ona o le maualuga maualuga o le vevela o le a-Alumina, Calcined Aluminas o loʻo faʻaaogaina i le tele o faʻaoga faʻamalosi, e le gata i le monolithic ma mea faʻatusa.

Galuega Fa'atino
Faʻalagolago i le tikeri o le viliina ma le lapoa tioata, Calcined Aluminas e faʻaaogaina le tele o galuega eseese i le faʻaogaina o meaʻai.

E sili ona taua:
• Fa'aleleia le fa'atinoga o oloa e ala i le fa'atuputeleina o mea uma o le alumina o nei fa'aputuga fa'aaogā mea fa'alenatura ina ia fa'aleleia atili ai le fa'asa'o ma mea fa'ainisinia.
• Fa'aleleia le fa'apipi'iina o fasimea e ala i le fa'aopoopoina o le aofa'i o fasi mea'ai lelei e maua ai le malosi fa'ainisinia ma le fa'asa'o.
• Fausia se matrix e maualuga le fa'afefe ma lelei le fa'ate'ia o le vevela e ala i le fa'aogaina o mea fa'apipi'i pei ole Calcium Aluminate Cement ma/po'o omea.
