*Fumed silica is applied to sealants, binders, sealants, and binders. Sealants and adhesives areimportant products with large quantities, wide applications, and a wide range of applications.
* Fumed silica should be used as an antibacterial material. By utilizing the large specific surface area, multi mesoporous surface structure, strong adsorption capacity, and unique physicochemical properties of fumed silica (fumed silica), functional ions such as silver ions are uniformly designed into the mesopores on the surface of fumed silica (fumed silica)
* Fumed silica is applied to high-pressure sodium lamps. The application of nanoparticles in infrared reflective materials mainly involves making thin films and multilayer films for use. This type of lamp can save 15% of electricity compared to traditional halogen lamps.
*Application of Gas-Phase White Carbon Black in New Organic Glass.And so on.
