Molecular Formula: Al2(SO4)3·xH2O
Basic Characteristics : including anhydrous and hydrous(18 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is Al2(SO4 )3 .18H2O; when weathering, the average molecular structure is Al2(SO4) 3 .14H2O, may appear off-white powder, or grayish flake, odorless, to change the taste from sweetness to slight astringency.
Uses: Mainly uses in the high-quality paper hammers the white manufacture and executes the mastic, afteruses in in titanium oxide powder manufacturing industry packageof membrane processing, but also uses in the papermaking executes the mastic and the tap water,the process water and the waste water processing flocculant; Production catalyst carrier, artificial jewel and other aluminum saltsand so on, but also widely serves as the fat clarifying agent petroleum deodorizes the decolorant; Concrete water-repellent and so on.
