For example, adding nano SIO2 to an isophthalic gel coat resin and testing its performance, the results showed that the strength, toughness, and ductility of the resin material are greatly improved, that is, the improvement in tensile strength and impact resistance. Due to the small size effect of nano-SIO2, the surface fineness of the material is greatly improved, and the wear resistance is greatly improved. The surface fineness is increased, the material is denser, and the water resistance and thermal stability of the material are also increased.

2. Add nano silica SIO2 to ceramics

With the development of science and technology, the requirements for high-performance ceramics are constantly increasing. On the surface of the experiment, adding a small amount of nano-AL2O3 to 95 porcelain can make the ceramic more dense, and greatly improve the thermal fatigue performance and strength performance. Using nano-SIO2 instead of AL2O3 to add to 95 porcelain can not only play the role of nano-particles, at the same time, it is also the second phase particles, and its effect is more ideal than adding AL2O3. In particular, the price of nano SIO2 is much lower than that of nano AL2O3, which helps reduce material costs.

3. Functional fiber additives

With the development of the national defense industry, the demand for functional fibers is becoming stronger, mainly including infrared shielding fibers, anti-ultraviolet fibers, high dielectric insulating fibers and electrostatic shielding fibers.

For example, the fiber that shields the infrared rays (4-25um) emitted by the human body can be added with nano-SIO2; the composite powder synthesized by the ratio of SIO2 and TIO2 is an important additive for anti-ultraviolet radiation; in the high-dielectric insulating fiber, nano-SIO2 It is also an important additive.

4. Reinforcing filler for new rubber materials

Some experts pointed out that to improve the strength and product quality of silicone rubber, it is none other than nano-SIO2. The rubber added with nano-SIO2 has significantly better elasticity and wear resistance than conventional silica filler rubber. Car tires made of nano-SIO2 rubber can increase the use effect by 1-2 times. The prepared high-elastic dyeing tank can be used for 10,000 to 12,000 times.

5, important additives for sealants and adhesives

Sealants and adhesives have high requirements for product viscosity, fluidity and curing speed. Adding hydrophilic nano-silica SIO2 to the sealant can quickly form a silica valley stone structure, that is, nano-SIO2 forms a network structure to inhibit colloidal flow, fast curing rate, improve bonding effect, and small particles increase the glue Tightness.

6, new organic glass additives

Adding surface-treated nano SIO2 in the production of plexiglass can resist ultraviolet radiation and achieve the purpose of anti-aging.

7. Additives for metal matrix composite coatings and integral metal matrix composites

For example, adding nano-SIO2 to the plating solution during the production of tinplate can produce a composite coating of SIO2/ZN, which is already available in Japan. SIO2/NI composite coating materials can be used to make gas turbine blades, high-temperature engine nozzles, etc.

8. New plastic additives

White carbon black is a reinforcing agent in conventional plastics, and the role of nano-SIO2 is not only reinforcing, but it also has many new characteristics. With its light transmission and small particle size, the plastic can be made denser, especially the translucency, strength, toughness, and waterproof performance are also greatly improved. According to reports, the water permeability of conventional PVC films is 1.5 times higher than that of nanomaterials.

Nine, the application of electronic assembly materials

Including the improvement of substrate materials, interlayer dielectric materials and packaging materials.

10. For biological cell separation and medical engineering

The surface of the nano-SIO2 is coated with a monomolecular layer. The choice of the coating layer is mainly determined by the type of cells to be separated. Generally, substances that have affinity with the cells to be separated are selected as the adhesion layer. The nano-SIO2 coated particles are uniformly dispersed in a colloidal solution of polyvinylpyrrolidone containing a variety of cells, and the required cells are quickly separated by centrifugal technology and the principle of density gradient.

In addition, in biomedical engineering, various nano-particles are injected into various parts of the human body to check, diagnose, and treat lesions. For example, nano SIO2 can be used for localized lesion treatment.

11. Application in optics

Nano particles as optical fiber materials can reduce the transmission loss of optical fibers. Made with nano SIO2 and nano TIO2 particles

12. As an anti-aging additive for coatings

To improve the anti-aging performance and smoothness of various coatings, adding nano-SIO2 is the key link. Because nano-SIO2 is a kind of anti-ultraviolet radiation material, and its extremely small particles have a large specific surface area, it can quickly form a network structure when the coating is dried, and colleagues can enhance the strength and smoothness of the coating. Therefore, the addition of nano SIO2 coatings can double the anti-aging performance, smoothness and strength, and the quality and grade of the coatings will naturally upgrade.

13. Important raw material for paper surface coating (porcelain clay)

Nano SIO2 has good transparency. As an important raw material of china clay, it can not only make the coating denser, but also make the surface smoother. Appropriate choice of particle size also has the effect of bleaching paper.

14. Artificial tooth materials and others

In recent years, dentists and nanomaterials workers have jointly developed bionic materials---artificial teeth. Nano SIO2 is one of the important raw materials.
