Aluminum Sulfate –for
paper making
Molecular Formula: Al2(SO4)3
XH2O
Properties: It is white or gray flake, particle or massive
crystallization. Apt to cake after moisture absorption
when laid in air for a long time. A little green because
of Fe2+, yellow when Fe2+ is oxided
to Fe3+. Soluble in water easily, and water
solution is acid.
Use: Used with saponified rosin as paper strength enhancing
binder to improve waterproof property. Also can be used
in printing and dyeing, leather, color agentia and wood
trust proof.
Packing: In 25kg or 50kg woven bags with inner film.
