The addition of nano SiO2 powder as an admixture to cement-based materials can improve many of the properties of cement-based materials. A large number of research results show that adding appropriate amount of SiO2 nanopowder to cement-based materials, due to the volcanic ash effect of nano SiO2 particle, nucleation effect and micro-filling effect, can significantly improve the early strength of ...

The organic/inorganic nanocomposite formed by dispersing the inorganic filler in a nanometer size in a general plastic matrix is called nanoplastic. In nanocomposites, nano-plastics have excellent properties such as high strength, heat resistance, high barrier properties, flame retardancy and excellent processability due to the nano-size effect of the dispersed phase, large specific surface area a...

Nano silica powder is a filler for reinforcing high-temperature vulcanized silicone rubber. The silica nanopowder aggregates have a good reinforcing effect on the silicone rubber. After adding SAT NANO nano silica powder to the rubber, a microcrystalline region with silica as a nucleus is formed, which increases the physical cross-linking point. Crystallization is more likely to occur and the stre...
