Silica has the advantages of small particle size, large surface area, large surface energy, strong adsorption capacity, high purity, high stability, reinforcement, thickening and thixotropy. At the same time, it also shows unique properties in light absorption, magnetism, thermal resistance, catalysis and melting point, and is widely used in various industries as additives, catalyst carrier, petrochemical industry, decolorizing agent, matting agent, etc. Rubber reinforcing agent, plastic filling agent, ink thickening agent, metal soft polishing agent, insulation insulation filler, senior daily cosmetic filler and spraying materials, medicine, environmental protection and other fields.

Coating industry
The refractive index of amorphous white carbon black is 1.457, which is similar to that of conventional resin coatings. Therefore, amorphous white carbon black is the first choice of extinction agent for high-grade coatings. It has good optical properties and can produce matte and extinction effects in varnish.

As we all know, wind power generation is a kind of environment-friendly green new energy. The adhesive used on the blade is a strong polar epoxy resin system. The blade has a large size and a large cross-sectional area, so it requires very high bonding performance and strength, viscosity, anti-flow hanging performance and anti-settlement performance. Because epoxy resin is a resin system with strong polar groups and strong polarity, generally using hydrophilic vapor silica, it is easy to appear solvent effect, that is, after just dispersing, the viscosity and suspension effect is very good, but placed for 7 to 10 days, the polar groups destroy the hydrogen bond forming a network structure, resulting in the cracking of hydrogen bond, dilute, thixotropy, packing precipitation and other problems. Therefore, it is recommended to use strong hydrophobic modified nano-level gaseous silica as the adhesive for wind blades, which has strong stability and avoids solvent-based effect.
