Introduction of Alumina Silica Gel-II

III. Preparation process

Silica-alumina gel is usually prepared by the reaction of water glass with sulfuric acid solution containing aluminum sulfate. In some processes, such as the preparation of silica-alumina gel from NaY molecular sieve mother liquor, the remaining Si O2 in the mother liquor will be recycled. Aluminum sulfate is added to the reactor to prepare silica-alumina colloid, and then it is re-dosed in the synthesis process.

IV. Market status

As an important industrial material, the application of silica-alumina gel in the market is gradually increasing. With the improvement of material performance requirements in various industries, silica-alumina gel has been widely used in aerospace, automobile manufacturing, construction engineering and other fields due to its excellent properties such as high strength, corrosion resistance and high temperature resistance.

V. New products and features

Silica-alumina gel (WS), also known as water-resistant silica-alumina gel, is a new product developed on the basis of silica-alumina gel. Its adsorption and separation performance is better than that of ordinary silica-alumina gel, and the water resistance of the particles is significantly improved, which increases the durability to humidity changes and pressure changes. This makes it more widely used in petrochemical or other fields of processing gaseous substances.

In summary, silica-alumina gel is an industrial material with multiple excellent properties and a wide range of uses, playing an important role in many fields.
