When silica sol is used as casting surface slurry, it can effectively improve the surface quality of castings and improve the surface finish of castings. When used as backing slurry, the coating can have good heat resistance and wear resistance, reduce the loss of molten metal to the mold at high temperature, and help demould. For the back layer quick drying silica sol, the drying time between layers can be reduced, the production efficiency can be improved and the cost can be reduced.

Silica sol is a transparent solution of silica, with the appearance of sky blue or light white liquid. Its solid content is generally 15% - 30%, non-toxic, harmless, good stability and very friendly to the environment. Charge neutralization is an important basis for the application of silica sol as clarifier or flocculant in the beverage industry. In acidic fruit juice and wine, negatively charged silica sol reacts with positively charged gelatin to achieve the purpose of flocculation and clarification. One colloid can excite another colloid and make it easy to precipitate by electrolyte. Mixing colloidal solutions with different charges can make it co precipitate.

In the process of semiconductor wafer polishing, the polishing time is short, the polishing speed is required to be fast, the surface quality is good, and the impurity residue is less, so as to avoid affecting the performance and yield of power devices. Silica sol has uniform particle size distribution, more effective particles for grinding and fast polishing rate; Moderate hardness, good dispersion and fluidity, not easy to precipitate and agglomerate, resulting in wafer scratch; At the same time, the silica sol has high purity, low residue and easy cleaning, which reduces the influence of wafer surface contamination.

The silicone gel inside the gel battery is a three-dimensional net structure made up of -Si-O- particles as skeleton. It can wrap the electrolyte in the interior. The gel system can prevent the transfer of the internal liquid, but it can still retain the liquid components by capillary action. When the silicon sol is injected into the gel, the gel skeleton shrinks, resulting in cracks in the gel running through the positive and negative plates. It provides a channel for reaching the negative electrode for the oxygen discharged from the positive electrode.

The dispersion of silica sol is used to form a chemical catalyst carrier to accelerate the chemical reaction. The silica sol has a surface area (250-350 ㎡ / g), good insulation (insulation resistance 8 * 108 Ω), strong wear resistance and adhesion (grade C). It is used as the carrier of petrochemical catalyst.

Silica sol is one of the coating auxiliary film-forming materials. It is a colloidal solution of inorganic polymer polymetasilicic acid with water as dispersion medium. Its silica particles are mostly spherical, single or multiple coalescence and dispersion, which can be firmly attached to the surface of substrate and filler particles. When the silicon solution loses water, the monomer silicic acid gradually polymerizes into high polymer silica gel. With the evaporation of water, the colloidal molecules increase, and finally form - sio-o-sio-coating. Its water resistance and heat resistance are obviously better than organic coatings. Its coating is dense and hard, does not produce static electricity, and it is difficult for various dust in the air to adhere.

Silica sol in the textile can make the fabric high in strength, the fabric size is stable, and the resilience is high; the combination of silica sol and synthetic oil can increase the cohesive force between the fibers, increase the tension resistance, improve the production efficiency, and can spin high yarn Number of products. It is mainly through the sol-gel reaction of silica sol to form a transparent and cohesive non-metal oxide film on the surface of the textile. This kind of silicon dioxide film has good adsorption and curing effect on other textile auxiliaries (such as polyvinyl alcohol, carboxymethyl cellulose, natural starch, dyes, etc.), thereby improving textile efficiency.
