Properties:
1.Nano silica with small particle size, pore, large specific surface area, high surface hydroxyl content, high reflection ability of ultraviolet, visible light and infrared, etc.
2.silica has the very high hardness and well stability, its melting, boiling point is also very high, has good chemical inertness and thermal stability.
Our silicon oxide nanopowder produce by liquid-phase method .
Use method:
1.Suggest add the silica about 0.5% -2% according to the general weight, special product could reach 10% above, should use by the general condition.
2.The key of how to embody the properties of the sio2. According to different system that disperse in the water, acetone, alcohol or other solution, use the shear, stirring, ultrasoun and other dispersion to disperse if necessary.
3.It could add the addictive to use for the oil system.
4.Used in rubber, plastic, resin and other organic macromolecule compound system, recommend choose organic surface modification to improve product dispersion and compatibility performance also enhance the comprehensive performance of materials.
Application of the silica nanopowder:
1.Fiber reinforced composite.
The oily silica nanoparticles fully and evenly dispersed in the resin material, can fully improve the resin base material performance. Can improve the strength and elongation, abrasion resistance and material surface finish, anti-aging performance.
2.Pigment.
Nano silica can improve oily coating suspended, poor stability of thixotropy, weather resistance and washing resistance, make the coating combined with wall strength greatly increased, increased the coating hardness, improves surface self-cleaning ability.
3.Ceramic.
Si02 can instead of nano A1203 , can improve the strength, toughness and hardness of ceramic materials and properties, such as elastic modulus,using nano Si02 composite ceramic substrate can improves the density of the substrate, toughness and degree of finish, sharply lower sintering temperature.
4.Further more sio2 nanopowder can apply to the rubber, cosmetic and so on, for the further information please contact me freely.
storage condition:
Nano silicon dioxide can be used lining plastic double paper bags and cardboard barrels packaging, non-toxic, non -combustible material handling, should be storage in a cool, dry shelter condition and avoid exposure.
