Aluminium sulfate
Product Description
Aluminium sulfate is an excellent flocculant which is suitable for industrial water and waste water
treatment in practical use.White powder granular, soluble in water, alcohol, insoluble in
water solution concentration cannot become acidic, mixing too low, generally for 5-10%, used as
water treatment agent, preparation good solution not adapt to long term storage, lest produce
hydrolysis, reduce the coagulation effect.
Features
Including anhydrous and hydrous(18 crystal water) type. Usually, the crystal separated out from aqueous solution at the normal temperature is Al2(SO)3 .18H2O; when weathering, the average molecular structure is Al2(SO4)3 .14H2O, may appear white powdery, with bright flake or crystalline flakelet, odorless, to change the taste from
sweetness to slight astringency.
Application
1. Widely used in paper making, water purification.
2. widely used as mordant, tanning agents, pharmaceuticals astringent, wood preservatives, foam fire extinguishing
agent, etc.
