Super absorbent polymer is a new type macro molecular material for water keeping. Super absorbent polymer has special structure and excellent hydrophilic group, which make it not dissolve in water but can absorb hundred times of water, and process superior water retaining capacity. Several excellent capacities of super absorbent polymer ensure the high quality of sanitary products, such as the high absorbing speed, good absorbence under load and excellent capacity of anti-moisture. Its nontoxic, harmless and nonpolluting with super water absorbing ability and water preserving ability. Thus it is a green and environment protecting high-tech product.

Commodity:Sodium Aluminate
Other names:Aluminium sodium dioxide; SodiumaluminatecaHO; dialuminum; oxygen(-2) anion; sodiooxysodium
Molecular formula: NaAlO2
CAS No.: 1302-42-7

Property: colorless, odorless, tasteless, strongly alkaline.

Solid type: white powder or granules, hygroscopic, readily soluble in water. The aqueous solution may absorb CO2 and form aluminum hydroxide precipitate. Addition of NaOH is required to increase stability.

Liquid type: transparent slurry, stable during storage life. Prolonged stay of diluted aqueous solution may cause aluminum hydroxide precipitate.

Use:
In the construction process, it can be used as leaking stoppage agent combined with the sodium silicate.
In paper-making, this product can mix with aluminum sulfate to be a good filling agent.
In water treatment, it can be used as additive of purifier.
