Introduction:
Sodium aluminate Introduction:
Sodium aluminate (NaAlO2) is a kind of inorganic compound, chemical formula is NaAlO2, white crystalline powder, easy to absorb moisture, easily soluble in water, insoluble in ethanol, aqueous solution is alkaline.
Sodium aluminate Introduction Usage:
Sodium Aluminate solution is widely used in the water and wastewater treatment markets. As an aluminum based coagulant manufactured as an alkaline (caustic) based solution, Sodium Aluminate offers advantages in systems where maintaining pH at a higher level is important. Unlike acid based metal salt coagulants, Sodium Aluminate will not reduce system alkalinity.
Product quality is ensured by managing each phase of manufacturing, from raw materials through finished product. Engineering, manufacturing, and quality assurance personnel maintain strict controls throughout the manufacturing process. This assures you consistent product quality and performance.
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.
