Application
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.
Further specifications customizable upon request.
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.
(We can produce as per clients' special requirement.)
