Note: We can supply different size products of nano sio2 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 Nano-silica is used as coatings and unsaturated resin thickener and thixotropic agent;
2. Silica nano particle is applied as flatting agents: furniture painted matte trend towards the direction of development, column perish varnish or paint; For coil coating, PVC, plastic wallpaper, raincoats, tents and other flatting agents may also use SiO2 nano powder as agent.
3. For polyethylene, polystyrene, polyvinyl chloride film, non-toxic anti-blocking agent / opening agent and so on can also use the Silica nano powder.
4. The nano-silica in the polymer industry is widely used in rubber, plastics, electronics, paint, ceramics (lining) porcelain, plaster, batteries, paints, adhesives, cosmetics, glass, steel, chemical fiber, plexiglass, environmental protection and many other areas.
SEM & XRD of nano sio2 powder:
Storage conditions:
nano sio2 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.
