Alumina Pa'u/α-Alumina Micropowder
Fa'amatalaga
O le pa'u alumina ose mea fa'aonanā ma le fua fa'a-kemikolo Al2O3.O se fa'aputuga ma'a'a maualuga ma le mea liusuavai o le 2054°C ma le fa'apuna o le 2980°C.O se tioata ionic e mafai ona faʻafefe i le maualuga o le vevela ma e masani ona faʻaaogaina i le gaosiga o mea faʻafefe.
Alumina paʻu o le alumina Al2O3 paʻu malosi, e masani ona gaosia mo le α-al2o3 alumina paʻu, β-al2o3 alumina paʻu, γ-al2o3 alumina paʻu o se faʻaoga ese.
α-Alumina micropowder
α alumina paʻu o loʻo i ai le mautu o mea faʻaletino ma vailaʻau, maualuga le maaa, faʻafefeteina, malosi faʻainisinia maualuga, faʻapipiʻiina, maualuga le vevela o le vevela, maualalo le aofaʻi o le mu, maualalo le maualuga o le faʻalauteleina o le vevela, faʻaleleia lelei o le vevela ma isi uiga.
α alumina e masani ona faʻaaogaina e pei o le abrasive, soʻo faʻamalosi, mea faʻafefe, mea faʻalelei, ma isi.
Gaosiga Fa'agasologa
1. Fa'atosina polo mill: fesoasoani e aveese mea leaga, fa'aleleia le fua o le liua o le fa'agasologa o le fana, ma fa'ateleina le saoasaoa o le tali;
2. Tunnel kiln roasting: fa'aauau ma mautu gaosiga e mafai ona iloa, ma le vevela vevela e mafai ona pulea sa'o;
3. Kiliki polo vili: olo le kikini i se lapo'a mana'omia.

Fa'atatauga
1. Refractory products.High alumina bauxite clinker ei ai le refractoriness e oo atu i le 1780 ℃, malosi mautu kemisi ma meatotino lelei faaletino.
2. Tu'u sa'o.O le klinker bauxite o lo'o gaosia i le pa'u lelei ma faia i ni fa'ailoga mo le fa'asolo sa'o.Faʻaaogaina i alamanuia a le militeri, aerospace, fesoʻotaʻiga, meafaifaʻaili, masini ma matagaluega faʻafomaʻi.
3. Aluminum alamanuia. Puipuiga o le atunuu, vaalele, taavale, mea eletise, vailaʻau, mea e manaʻomia i aso uma, ma isi.
4. Alumini silicate alava refractory;faʻaaoga le magnesia ma le bauxite clinker e pei o mea mataʻutia, oneone ma le bauxite clinker e pei o mea mata, oneone ma le bauxite clinker e pei o mea mata, gaosia le sima bauxite, mea abrasive, alamanuia keramika ma alamanuia vailaʻau e mafai ona gaosia eseese tuufaatasiga o alumini.
