Nano silica has a wide range of uses, mainly in the following fields:

(1) Electronic packaging materials
The curing time (2.0-2.5h) and curing temperature can be reduced to room temperature, which can significantly improve the sealing performance of the device and increase the service life of the device.

(2) resin composite materials

The properties of resin base materials can be improved by fully and uniformly dispersing nano silica particles into resin materials. Including: A improved strength and elongation; B improve wear resistance and improve the surface finish of the material; C Aging resistance.

(3) Plastics
The use of nano silicon dioxide light transmittance, small particle size, can make plastic become more dense, adding silicon dioxide in polystyrene plastic film, can improve its transparency, strength, toughness, waterproof performance and anti-aging performance. The main technical indexes (water absorption, insulation resistance, compressive residual deformation, flexural strength, etc.) of polypropylene, a common plastic, have reached or exceeded those of nylon 6.

(4) coating
It can improve the suspension stability, thixotropy, weather resistance, washing resistance, etc., so that the combined strength of the film and the wall is greatly improved, the hardness of the film is increased, and the surface self-cleaning ability is also improved.

(5) rubber
Silica is known as white carbon black, adding a small amount of nano Si02 in ordinary rubber, the strength, wear resistance and anti-aging properties of the product have reached or exceeded high-grade rubber products, and can keep the color unchanged for a long time. Nano modified color EPDM waterproof roll material, its wear resistance, tensile strength, flexural resistance, aging resistance are improved obviously, and the color is bright, excellent color retention effect.

(6) Yan (dye) material
By adding nano-Si02 to the surface modification of organic pigment (dye), not only the anti-aging performance of the pigment (dye) is greatly improved, but also the brightness, hue and saturation index are also improved to a certain extent, which greatly expands the grade and application range of organic pigment (dye).

(7) Ceramics
Nano-si02 instead of nano-A1203 can not only play the role of nano-particles, but also the second phase particles, which can improve the strength, toughness, hardness and elastic modulus of ceramic materials. Nano-si02 was used to composite ceramic substrates, the density, toughness and finish of the substrates were improved, and the sintering temperature was greatly reduced.

(8) sealant, binder
The addition of nano-si02, coating a layer of organic material on the surface, forming a network structure, forming a silica structure, so that it has hydrophobicity, can inhibit colloidal flow, accelerate the curing speed, improve the bonding effect, increase the sealing and impermeability of the product.

(9) FRP products
The grafting and bonding of nano-particles with organic polymer can increase the toughness, tensile strength and impact strength, and heat resistance.

(10) Drug carrier
Nano Si02 can be used as the carrier to achieve a good sustained release effect.
