Note: We can supply different size products of hydrophobic silicon dioxide powder according to client's requirements.
Nano-silica or nano-silicon dioxide is an inorganic chemical materials, commonly known as silica. SiO2 has the ultrafine nanometer size range 1 ~ 100nm, and therefore has many unique properties, such as having optical properties against UV, other materials can be improved aging, strength and chemical resistance. Nanoscale silicon dioxide is an amorphous white powder, non-toxic, tasteless, non-polluting, and environment friendly which could be widely used in different kinds of industries.
Nano-silica is extremely important high-tech ultra-fine inorganic new material, because of its small particle size, surface area, and strong surface adsorption, surface energy, high chemical purity, good dispersion properties, and also has a specific performance like heat resistance, resistance. With its superior stability, reinforcement and thickening in many disciplines and areas of unique characteristics which also shows that SiO2 plays an irreplaceable role. Nano-silica, which is also called "Carbon black", is widely used in various industries as additives, catalyst support, petrochemical, bleaching agents, matting agents, rubber reinforcing agent, filling plastic agent, ink thickener, soft metal polishing agent, filler insulation insulation, senior cosmetics packing in various fields and coating materials, medicine, environmental protection and so on.
Application of nano sio2 powder:
1. Rubber modification, sealant ceramic toughening, binder modification, functional fiber additive, plastic modification, anti-paint aging additive;
2. Ceramic, nano ceramic, composite ceramic substrate;
3. Polymer: can increase the thermal stability and aging resistance of the polymer;
4. Flame retardant materials, coatings, advanced grinding media, cosmetics and other products;
5. The color rubber products produced by adding a small amount of nano-SiO2 in solution-polymerized styrene-butadiene and chlorinated polyethylene have the properties of toughness, strength, elongation, flexural resistance, anti-UV aging and heat aging, all of which exceed or exceed ternary Ethylene propylene rubber;
6. Adding a small amount of nano-silica in traditional coatings, it solves the problems of poor suspension stability, poor thixotropy, poor aging resistance and low finish.
SEM & XRD of hydrophobic silicon dioxide powder:
Storage conditions:
hydrophobic silicon dioxide powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
