What are the uses of silica sol

1. Used in precision casting industry: used instead of ethyl silicate, non-toxic. It can not only reduce costs, improve operating conditions, have high dimensional accuracy, good casting finish, can make the shell strong, and the shape is better than using water glass. .High-temperature-resistant coatings used for casting molds can make the coating have better heat resistance, reduce the loss of molten metal to the mold at high temperatures, and facilitate demolding.

2. Used in the coating industry: it can make the coating strong, with the advantages of water resistance, fire resistance, stain resistance, high temperature resistance, high hardness of the coating film, bright color, non-fading, etc. It can also be used in acid-resistant, alkali-resistant, fire-retardant coatings and remote coatings. Infrared radiation paint.

3. Binders used in refractory materials: have the characteristics of high bonding strength and high temperature resistance (1500-1600℃).

4. Used in the textile industry: it can be used as a sizing additive for diameter spinning to reduce the breakage rate. It can be used in fabric dyeing because it has adhesive properties and can form an excellent protective solution to increase the adhesion of dyeing, etc.

5. Used in the papermaking industry: as a treatment agent for photosensitive paper and an anti-adhesive agent for cellophane; other office papers can improve the printing effect and make the color more vivid after treatment.

6. Application to catalysts: In the production of catalysts, under certain conditions, it can be used as a carrier to accelerate the catalytic speed to improve production efficiency.

7． Petroleum applications: Using silica monomer as a catalyst in the production of aromatic nitriles opens up a new way to improve the recovery rate of aromatic nitriles. In the petroleum industry, silica sol is used as a binder and catalyst.

8. Application in batteries: Ordinary lead-acid batteries have a short service life. If this product is used, it can be configured as an electrolyte for solid batteries, which greatly improves the service life of the battery. At the same time, the ordinary electrolyte sulfuric acid will cause a sharp turn when the motor vehicle turns. It is easy to overflow, but the use of solid battery electrolyte solves this problem very well, effectively preventing the leakage and overflow of sulfuric acid and avoiding environmental pollution.

9. Application in steel rolling: Adding a certain amount of silica sol to the coating solution can improve the appearance, insulation performance, and heat resistance of the insulating coating, reduce the expansion coefficient of the coating, and improve the magnetism of silicon steel.

10. Application in enamel: In the manufacture of enamel, adding silica sol can reduce the expansion coefficient to improve the adhesion of tetrafluoroethylene. Adding 25-30% silica sol to glass can obtain high-quality silicic acid. Boron glass.

11. Application in broadcasting equipment: Silica sol can be used as a binder for picture tubes in television sets; when making transformer cores, it is used as a binder to bond silicon steel sheets into one piece, and can also play an insulating and high-temperature-resistant role ,good results.

12． Application in ceramic fiber: The aluminum silicate fiber is impregnated with silica sol, and a coagulant is added to make it into a warm adhesive, which can be used as thermal insulation material; used as a surface adhesive for refractory bricks in high-temperature furnaces, with high bonding strength. It is resistant to high temperatures (above 1000℃) and saves energy. It is economical and convenient to modify the furnace.

13. Semiconductor component polishing agent: Using large particles of silica sol as a single crystal silicon polishing agent not only has good effects, but also has fast polishing speed.

14. Application in foam rubber: Adding 5% silica sol to dry rubber can strengthen the porous foam rubber by 20%. For a certain volume of rubber, 20% of the rubber can be saved due to the increased elasticity.

15. Silica sol can be used as a clarifying agent for soy sauce and rice wine without affecting the color, aroma and taste. Silicon is non-toxic to the human body and has certain anti-cancer effects.

16. Chemical fiber decorative items treated with silica sol can reduce their pollution by two times. It can be seen that silica sol is also an effective antifouling agent for surfaces such as wall coverings.

17. Anti-slip floor wax made from silica sol has become very popular in industry and civil use. It has good anti-slip effect and does not affect the soft luster.

18. Silica sol is an excellent water purifier. After it is mixed with aluminum sulfate, it can condense and remove metal salts and suspended turbidity in the water.

19. Adding a small amount of silica sol to the fuel can prevent combustion ash from accumulating on the diesel engine.

20. Using silica sol as a binder for far-infrared radiation coatings is good, resistant to high temperatures, and does not affect radiation.
