What are the properties of various industrial silica sols?

分享到:

硅Sol is non-toxic, odorless, durable, and has the characteristics of high bonding strength, high hardness, heat resistance, solvent resistance, scrub resistance, and low price with inorganic materials (including cement and other basic materials). They are all formed by forming chemical bonds between organic and inorganic substances through an organic adsorption layer, or combined through electrostatic interaction, and their performance is complementary.

The application of silica sol in coatings can enhance the coating.


The application of the product can also play a role in preventing pollution, so that the product will not be polluted during use.


The paint is easy to adhere to dust during use, which affects the use effect. The use of silica sol can improve the dustproof function of the coating, thereby ensuring better construction and use effects. Because this material can firmly adhere to the surface of the object under the action of moisture, it can be coated on the coating to achieve the purpose of anti-aging.


It is used in the coating industry to make the coating firm, with the functions of anti-fouling, dust-proof, anti-aging and fire-proof.


Thin shell casting, strong shell shape, high finish of casting. Its molding quality is better than that of water glass. Replacing ethyl silicate with ethyl silicate can reduce costs and improve operating conditions.


Silica sol with high specific surface area can be used for catalyst manufacturing and catalyst carrier.


It can be used in papermaking industry as anti-sticking agent for cellophane, pretreatment agent for photographic paper, anti-skid agent for cement bags, etc.


Because the colloidal particles are very fine (10-20nm) and have a large specific surface area, the particles themselves are colorless and transparent, and will not affect the natural color of the covered object.


Low viscosity, water can penetrate anywhere, so when mixed with other substances, the dispersion and permeability are very good.


When the water in the silica sol evaporates, the colloidal particles will firmly adhere to the surface of the object, forming silicon-oxygen bonds between the particles, which is a good adhesive.
