Silica has excellent properties such as small particle size, large specific surface area, large surface energy, strong adsorption capacity, high purity, high stability, reinforcement, thickening and thixotropy. At the same time, it also shows unique performance in light absorption, magnetism, thermal resistance, catalysis and melting point. It is widely used in various industries as an additive, catalyst carrier, petrochemical, decolorizing agent, matting agent, rubber reinforcing agent, plastic filler, Ink thickener, metal soft polishing agent, insulation and insulation filler, advanced daily cosmetics filler and spraying materials, medicine, environmental protection and other fields.

1. Coatings 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 for high-end paint matting agents and has good optical properties when used in varnishes, which can produce matte and matte effects.

As is well known, wind power generation is a development of environmentally friendly green new energy. The adhesive used on the blades is a strong polar epoxy resin system. The blades have a large size and cross-sectional area, so the requirements for bonding performance and strength are extremely high. The requirements for viscosity, anti sagging performance, and anti settlement performance are extremely high. Epoxy resin is a resin system with strong polar groups and strong polarity. Generally, hydrophilic vapor phase silicon dioxide is used, which is prone to solvent effect. That is, after rigid dispersion, the viscosity and suspension effect are very good. However, after being placed for 7 to 10 days, the polar group destroys the hydrogen bond forming the network structure, leading to hydrogen bond cracking, thinning, no thixotropy, filler precipitation and other problems, It is recommended to use strong hydrophobic modified nano level fumed silica as the adhesive for wind turbine blades, which has strong stability and avoids solvent type effects.

2. Rubber industry
White carbon black is widely used as an environmentally friendly rubber reinforcing agent. Silicone rubber has excellent properties such as high temperature resistance, insulation, thermal insulation, chemical resistance, and pollution resistance, and plays an irreplaceable role in fields such as national defense industry, building decoration, aerospace, etc.

When used as a tire tread reinforcement agent, it can reduce rolling resistance while maintaining excellent wet slip resistance. It can also save fuel and reduce automobile exhaust emissions. At the same time, rolling resistance can be reduced by about 30%, making it an important raw material for manufacturing "green tires".

After AMI modification of white carbon black particles, the interaction between particles decreases and agglomeration decreases. When used for doping rubber, it has a certain promoting effect on rubber vulcanization, and the rubber molecular chains are arranged more orderly.

3. Daily life
In recent years, high water absorbent resin has been a new type of polymer fine chemical product, widely used in industrial products, daily hygiene products, medical, agriculture, civil engineering and other fields, especially in daily hygiene products and agriculture, where the demand for application is increasing. High water absorbent resin has the advantages of small particle size, high salt absorption rate, fast absorption speed, and low monomer residue. It is commonly used in daily hygiene products, including baby diapers, adult diapers, ultra-thin diapers, sanitary napkins, pet pads, care pads, absorbent paper, dust-free paper, toothpaste, etc. In the production processes of baby diapers, diapers, and sanitary napkins, the quantification of high water absorbent resin is a key link. The role of fumed silica in water absorbing resins is to increase the fluidity of the resin, prevent agglomeration, facilitate the flow of high water absorbing resins in pipelines, avoid pipe blockage, and improve production efficiency.

4. Biofiltration
Biofiltration is a typical air pollution control process for treating volatile organic compounds. The mass transfer of hydrophobic volatile organic compounds to biofilms is limited, resulting in lower removal efficiency of biofilms. In order to enhance the migration of hydrophobic organic compounds, the addition of hydrophobic gas-phase silica in the biofilter can have a removal effect on pentane and other substances.
