Scope of Application
1. Chemical industry, sealants, fiberglass, high-grade organic glass;
2. Electronics, electronic packaging materials, ferrite materials, batteries;
3. Ceramics, nano-ceramics, and composite ceramic substrates; adding nano-SiO2 to ceramics significantly reduces their brittleness, enhances toughness by several times or even dozens of times, noticeably improves surface smoothness, lowers firing temperatures, and upgrades product quality.
4. Drug and pesticide carriers, artificial teeth; in agriculture, treating seeds with nano-SiO2 can increase the yield of vegetables and crops and accelerate their maturation; food packaging bags containing nano-SiO2 help preserve the freshness of fruits and vegetables.
5. Cosmetics industry, UV-resistant materials: UV light shielding reaches 99%, but the particle size added must not be too small, otherwise it will clog sweat pores and affect health. However, the particle size must not be too large either, otherwise UV absorption will deviate from this wavelength range.
6. Antibacterial Materials: Leveraging the large specific surface area, abundant mesoporous structure, strong adsorption capacity, and unique physicochemical properties of SiO₂, antibacterial ions such as silver ions can be uniformly incorporated into the mesopores on the SiO₂ surface. This enables the development of efficient, durable, high-temperature-resistant, and broad-spectrum antibacterial nanopowders.
7. Optics, lighting fixtures;
8. Military Industry: Used for stealth coatings and armor composite materials.
9. Building and waterproof materials.
10. Plastics: In plastics, SiO₂ is primarily used as a reinforcing agent. Additionally, due to the light-transmitting properties and small particle size of nano-SiO₂, it can make plastics denser. When added to plastics, it improves transparency, strength, and toughness, while also enhancing waterproof performance and resistance to aging.
11. Coating: Nano-SiO₂ is an amorphous white powder with optical properties such as ultraviolet absorption and infrared reflection. Its ultraviolet absorption rate can reach over 70%, and its infrared reflection rate can also exceed 70%. It improves the thermal and chemical stability of coatings. Due to its insufficient surface coordination, it exhibits strong activity, enabling it to adsorb pigment particles such as colorants, thereby reducing pigment degradation caused by irradiation and minimizing the "chalking" phenomenon of the coating film. During the drying process of the coating film, nanoparticles can form a network structure, significantly enhancing the coating film's resistance to aging, gloss, strength, and anti-corrosion performance.
12. Rubber: Nano-SiO₂ serves as a reinforcing agent for rubber. By controlling the particle size of SiO₂, rubber with varying sensitivity to different light wavelengths can be produced. This enables the creation of rubber that is resistant to ultraviolet radiation, reflective to infrared light, or highly insulating. Additionally, SiO₂ can be used to modify tire sidewalls for the production of colored tires.
13. Pigments: Enhance brightness, hue, saturation, etc.
