Sodium aluminate Uses
Water Treatment
Sodium aluminate has wide uses in water treatment processes, particularly in the treatment of drinking water and wastewater. It helps in the removal of impurities, such as suspended solids and phosphates, by forming aluminum hydroxide flocs that can be easily precipitated.
Paper Industry
As a sizing agent in the paper industry, it helps control the pH of the pulp and improves the paper’s resistance to aging and yellowing.
Textile Industry
Beta-Alumina is as a mordant in textile dyeing and printing processes. It helps fix dyes onto the fabric and enhances the colorfastness of the dyes.
Cement Industry
In cement formulations,Sodium aluminate can contribute to the acceleration of the cement-setting process. Especially under low temperature conditions like well, tunnel, it is an ideal additive for rapid construction and rapid cement setting.
Additionally, Beta-Alumina has uses in fire retardants, oil refining, pharmaceutical, waste water treatment, coatings, adhesive and sealant industry.
