sodium aluminate

Sodium aluminate 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: Concrete engineering: used in combination with water glass as concrete adhesive; concrete solidifying agent, promotes concrete solidification. Papermaking: used in combination with aluminum sulfate as filling agent. Water treatment: flocculant aid, reduces water hardness and accelerates floc settling. Petrochemical: catalyst or catalyst carrier, coating primer. Others: in textile, dye/printing, pharmacy, rubber, detergent, metal surface treatment, etc.
