Sodium Alumina,Sodium Aluminium Oxide,Sodium Mataaluminate
Property: colorless, odorless, tasteless, strongly alkaline.
Solid type: It presents in white powder or granular, which is rapidly dissolved and become clarification in the water. It easily absorp moisture and CO2 in the air; after dissvolved in the water, the solution earily precipitates the Aluminum hydroxide, so it needs to add the NaoH to keep the stability.
Liquid type: It is transparent slurry and stable for long time. After cold water dilution, it will precipitate the Aluminum hydroxide.
Main Use:
Concrete engineering:
Sodium aluminate is used in combination with water glass as concrete adhesive; concrete solidifying agent, promotes concrete solidification.
Papermaking:
Sodium aluminate is used in combination with aluminum sulfate as filling agent.
Water treatment:
Sodium aluminate is used in flocculant aid, reduces water hardness and accelerates floc settling.
Petrochemical:
Sodium aluminate is used in catalyst or catalyst carrier, coating primer.
Others:
Sodium aluminate is used in in textile, dye/printing, pharmacy, rubber, detergent, metal surface treatment, etc.
