Product Description

Product Description

The alumina sol derived from this product possesses characteristics such as weak acidity, small nano-sized particles, large specific surface area, high transparency, uniform dispersion, long-term stability without aggregation, adhesive properties, thixotropy, adsorption, and on-demand preparation and usage. These features make it suitable for a wide range of applications.

Fetures

1. The material has nanoparticles with a small particle size, less than 5nm.

2. The product has a large specific surface area, approximately 250m²/g.

3. It exhibits weak acidity with a pH value between 4-5, addressing the release of acidic gases during the use of aluminum sol.

4. It does not contain chloride ions.

5. The powder is prepared and used immediately, addressing the issue of low solid content and easy coagulation in colloidal solutions. 

6. The nanoscale particles disperse uniformly and transparently, remaining stable without aggregation for an extended period.

Applications

1. Application in the Refractory Industry
Aluminum sol has adhesiveness, film-forming properties, and heat resistance. It can be used as a binder for inorganic fibers such as glass fibers, asbestos, ceramics, etc., and can be sprayed as needed. It can also be mixed with refractory material powder or inorganic fibers for the preparation of high-temperature refractory materials.

2. Application in the Inorganic Refractory Fiber Cotton Industry
As an aluminum source, aluminum sol has a certain viscosity. Through the spinning process, it forms fiber precursors, which, after high-temperature treatment, result in various types of inorganic refractory fiber cotton containing aluminum oxide. Examples include aluminum oxide fibers, aluminum silicate fibers, high silica-alumina fibers, etc.

3. Application in the Aerogel Industry
Used as an aluminum source to form hydrogels, or combined with silica to form silica/alumina composite hydrogels. After drying, composite aerogels are obtained, which are used to enhance the rigidity and temperature resistance of aerogels.

4. Application in Petrochemical Catalysis
Aluminum sol, as a precursor, can be used to prepare active alumina, high-purity alumina, and alumina-based catalyst supports or molecular sieves in the field of petrochemical catalysis.

5. Application in the Textile Fiber Industry
Used in the treatment of textile fibers to enhance fiber elasticity, smoothness, anti-static properties, and dust resistance. It is also used in the treatment of fishing nets, climbing ropes, etc., to increase the friction coefficient, improve strength, impact resistance, etc.

6. Application in the Industrial Fabric and Fleece Industry
Applying a layer of aluminum sol to the surface of industrial filter cloth and fleece can provide anti-static properties, enhance the smoothness and feel of the material, and increase its strength and wear resistance.

7. Application in the Ceramic Industry
Aluminum sol, with its refractoriness, adhesiveness, and film-forming ability, can be added to ceramic articles to increase the green strength of the raw clay. After subsequent processes such as shaping and firing, various ceramic products can be produced.

8. Application in the Papermaking Industry
Aluminum sol, used as an inorganic filler and binder in the papermaking industry, can enhance the strength, smoothness, whiteness, and moisture resistance of paper.

9. Application in the Coating Industry
Adding to various emulsion coatings such as acrylic, polyurethane, epoxy resin, vinyl acetate, silicone, etc., can enhance the strength, hardness, heat resistance, and anti-static properties of the coating films.

10. Applications in Other Industries
Improving battery materials and separators to enhance battery capacity and lifespan; used for surface polishing of tiles, sheets, etc., to achieve a transparent and smooth object surface; used in cosmetics, ointments, etc.
