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.
Characteristics: White powder or tiny crystalls, nodorousand salty, easily soluble in water,insoluble in alcohol, presenting slightly alkalinity, decomposed when heating. Decomposed slowly when exposed to moist air.
