O polo alumina faʻagaoioia e tele faʻaoga ma faʻamatalaga, lea e mafai ona aoteleina i 5 galuega tetele.

Alumina desiccant: E masani ona faʻaaogaina pores atiaʻe o polo alumina faʻagaoioia ma malosi sili ausa vai absorption gafatia.O le a le faʻaleagaina pe malepe pe a uma ona faʻafefe vai, ma o le a le afaina ai meafaigaluega.E faʻaaogaina lautele i compressors ea, dryers ma isi meafaigaluega.Fa'amatalaga masani o 3-5mm 4-6mm.

Lagolago alumina: faʻaaogaina le tele o le pore volume structure ma le vaega faʻapitoa o polo alumina faʻagaoioia, ma faʻaaoga le van der Waals malosi e faʻafefe ai le vaifofo manaʻomia i totonu o le pore volume structure o polo alumina faʻagaoioia, ina ia faʻagaoioia polo alumina. ua impregnated i se faagasologa faapitoa E i ai le galuega tutusa e pei o le catalyst solution.E mafai ona faʻaogaina le tele o mea faʻapipiʻi, e pei o le: potassium permanganate solution, organic solution, mea e le masani ai, metala taua ma isi mea faʻapipiʻi eseese, o faʻamatalaga masani e 2-3mm.3-5mm.

Alumina fluoride aveese sui: E masani ona faʻaaogaina le super pores ma le sili atu le tele o vaega faʻapitoa o polo alumina faʻagaoioia.O lo'o i ai le malosi fa'aletino lelei mo le fluoride ma le arsenide i le fofo.E le oona ma e le afaina ma e le afaina ai le inu vai.Faʻaaogaina i le vai eleele ma vai inu vai faʻafefeteina galuega, o le tele masani o le 2-3mm.
