Aluminum sol with a pH value of 4 or above is generally sold in the international market, and the acidic gas released during use is more than ten times lower than acidic aluminum sol with a pH value of 2-3. For a long time, China has been researching and developing aluminum sol products with a pH value of 4 or above. Most manufacturers are in the trial production stage, but the products they produce are generally in a milky white paste form, and their particle size is still at the micrometer level.

In order to shorten the gap with international standards, our company uses high-purity aluminum alcohol as raw material, hydrolyzes aluminum alcohol to generate AlOOH, and uses alkali as a gel solvent for gelation. We have developed various aluminum sol products with pH values of 7-9, particle size of 10 nanometers, and good dispersibility. The products have more typical colloidal characteristics, and their appearance is a milky white colloid. The microstructure of the colloidal particles is feather like, negatively charged, non-toxic, odorless, non volatile, and non flammable. After high-temperature dehydration, they generate active alumina or high-purity alumina.

Features: This aluminum sol has characteristics such as adhesive viscosity, thixotropy, easy dispersibility, water solubility reversibility, suspension, positively charged, adsorption, stability, etc,

Usage: It can be widely used as a molding binder for high-temperature and refractory materials such as petrochemical catalysts, aluminum silicate fibers and ceramics, an additive for ceramic enamel glaze, an antistatic agent for velvet making and electrostatic weaving and flocking, a film-forming agent and antistatic agent for textile and fiber product treatment, precision cast alumina casting materials, emulsifiers and stabilizers for pigments and coatings, surface treatment agents for photo paper, greenhouse anti fog agents, waterproofing agents, etc. It can also be used in various industries such as inorganic fibers, active alumina, high-purity alumina, enamel, daily necessities, papermaking, etc.

1、 By utilizing the adhesive, film-forming, and wear resistance of aluminum sol, it can be used as an adhesive for inorganic fibers such as glass fibers, asbestos, and ceramic fibers, and can form any shape.

2、 Ceramic paper can be made using aluminum sol and silica gel fibers, etc

3、 Mixing aluminum sol with refractory powder or inorganic fibers can make heat-resistant coating materials of any viscosity, casting refractory materials, and spraying materials.

4、 Adding it to the manufacturing of ceramic utensils not only does not reduce the fire resistance of raw materials, but also increases the strength of the green body, making it possible to produce various ceramic products

5、 In textile fibers, it can increase smoothness, improve impact resistance, and enhance wear resistance

6、 Used in the papermaking industry to improve the smoothness, whiteness, and humidity resistance of paper, and can also be used as a surface treatment adhesive for processed paper

7、 Can be used as a cationic emulsifier

8、 Can be used to prepare catalyst carriers or molecular sieves

9、 Can be used for transparent coatings, fluorescent lamp coatings, and lamp adhesive coatings
