Superfine 20-30nm with 99.8% Purity Nano Silica Powder
Application for nano silica powder:
1. Adding nano-SiO2 to gel coat resin, Mohs
hardness increased from 2.2 up to 2.8-2.9 grade, wear resistance is increased
1-2 times, thus generating silica nanoparticles and organic polymer grafting
and cooperation with key , make the material toughness increases, so the
tensile strength and impact strength increased by more than one times, heat
resistance is also greatly improved.
2. Nano-silica surface coated with a layer
of organic material, so that it has hydrophobicity, add it to the sealant will
soon form a silica structure, namely the formation of nano-silica colloidal
inhibit the flow of the network structure, speed up fixed speed, improve
bonding effect.
3. Added silica nanoparticles to the
composite ceramic substrate, the substrate not only improve the density, toughness
and finish, but also significantly lower the sintering temperature.
4. Nano-silica on the surface modification
treatment of organic pigments, not only the pigment anti-aging properties
increase, but also the brightness, hue and saturation and other indicators were
also improved to some extent.
5. Nano-silica light, small particle size, can make
plastic becomes more dense, after adding silica into polystyrene plastic film,
not only improve its transparency, strength, toughness, and water resistance and
anti-aging properties also improved significantly.
