Fumed silica is a nanometer white powder created by the hydrolysis of silicon halide at high temperature in an oxyhydrogen fire. It is a sort of amorphous silicon dioxide item, the primary fragment size is between 7 ~ 40nm, the accumulation fragment dimension is about 200-500 nm, the particular surface is 100 ~ 400m2/g, high purity, as well as SiO2 material is not less than 99.8%. The vapor phase silica aggregates with neglected surfaces include a variety of silica hydroxyl groups.
One is an isolated, undisturbed complimentary hydroxyl group; The various other is adhered silyl groups that are connected and also develop hydrogen bonds to each other. The vapor phase silica accumulations with the untreated surface area are accumulations having several -Oh substances, which can conveniently develop a consistent three-dimensional network structure (hydrogen bond) in the fluid system. This three-dimensional network framework (hydrogen bond) with exterior force (shear pressure, electric pressure, and so on) will be damaged, the medium becomes thin, the viscosity goes down, as well as once the exterior force disappears, the three-dimensional framework (hydrogen bond) will certainly recover itself, the viscosity climbs, that is, this thixotropy is relatively easy to fix.
Fumed silica is just one of one of the most crucial new inorganic materials. It has a tiny particle size, big certain area, strong surface adsorption, large surface area energy, high chemical pureness, great dispersion efficiency, thermal resistance, resistance, as well as various other elements of particular performance. In addition, its high security, its strengthening result, thickening, and thixotropy, in lots of fields of special features make it irreplaceable.
It is widely utilized in different sectors as ingredients, catalyst service providers, petrochemical, decolorizing representative, matting representative, rubber reinforcing representative, plastic loading agents, ink thickening representatives, steel soft polishing representatives, insulation and adiabatic filler, advanced daily cosmetic filler, as well as splashing materials, medicine, environmental management, and also other areas.
Fumed silica primarily has 2 “sex”& rdquo;: hydrophilic and also hydrophobic. People can use physical, chemical, and mechanical approaches to handle the fumed silica surface or user interface, in order to transform its chemical as well as physical homes of the fumed silica surface area, such as surface power, surface wettability, electric, adsorption, and also response attributes, surface structure and functional teams, and so on. For that reason, it can satisfy the modern-day brand-new product, new innovation, as well as the demands of the advancement of new technology. Hydrophobic fumed silica applications
Enlarging of polar fluids, such as epoxy resins; Silicone elastomer reinforcement; High enhancement, as in shaped products; Excellent hydrophobicity, boosting anticorrosion; Enhanced dielectric residential properties, as in wire composites; Powder circulation AIDS, such as powder finishings and also fire extinguishing agents; Boost scratch resistance in layers and plastics.
