This product is amorphous aluminum hydroxide, and its water suspension is neutral. This product has good reactivity with acids and bases, so it can be used as a raw material for producing various aluminum compounds such as high-purity organic acid aluminum salts. Due to its high surface charge, it exhibits excellent adsorption characteristics, and is often used as an adsorbent, catalyst, acid absorber, molecular sieve, etc.


Production Technology

Firstly, industrial aluminum hydroxide and industrial sulfuric acid are used as raw materials to react and generate a solution of aluminum sulfate. Then, the aluminum sulfate solution undergoes neutralization reaction with the ammonium bicarbonate aqueous solution. Finally, the obtained product is filtered and dried to get amorphous aluminum hydroxide dry gel.

Features

Our factory uses high-quality industrial aluminum hydroxide, sulfuric acid, and ammonium bicarbonate as starting materials, greatly reducing the content of arsenic, lead, iron, heavy metals, etc. in the products. In addition, there is no introduction of sodium in the production process, ensuring that the products have excellent chemical properties.

Relying on our mature production process and more than 30 years of industrial production experience, in the later stages of production processes such as refining and drying, it is ensured that the product has a smaller bulk density, a larger specific surface area and a good fluidity, thereby possessing better physical properties.

The product has stable product quality and excellent physicochemical properties, making it highly favored in petrochemical, coal chemical, thermosetting plastics, thermoplastic plastics, synthetic rubber, coatings, and building materials high-end catalyst carriers and adsorbents such as low strain, copper, zinc, etc. in. Due to its stable activity and long lifespan, it has been widely praised by many manufacturers

The product has stable product quality and excellent physicochemical properties, making it widely used in fields such as petrochemical, coal chemical, thermosetting plastics, thermoplastic plastics, synthetic rubber, coatings, building materials, etc. The product is particularly favored in low-temperature fission, molecular sieves, and adsorbents. Due to its stable activity and long service life, it has been widely praised by many manufacturers.
