White carbon black is the general term of white powder X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultra-fine silica gel, as well as powder synthetic aluminum silicate and calcium silicate. White carbon black is a porous substance, and its composition can be represented by SiO2 · nH2O, where nH2O exists in the form of surface hydroxyl groups. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents, and acids (excluding hydrofluoric acid). High temperature resistance, non flammable, odorless, odorless, and excellent electrical insulation.

Purpose
Due to the series of advantages of white carbon black products, it can be widely used in many fields. Folding rubber products
White carbon black is used in colored rubber products to replace carbon black for reinforcement, meeting the needs of white or semi transparent products. Silica also has super adhesion, tear resistance, heat resistance and aging resistance, so it can also replace part of carbon black in black rubber products to obtain high-quality rubber products, such as off-road tires, engineering tires, radial tires, etc.

Agricultural chemicals
In agricultural chemicals, such as pesticides and high-efficiency spraying fertilizers, using white carbon black as a carrier, diluent, or disintegrant can improve the suspension rate when used as an disintegrant in water dispersible granules (WDG). It is recommended to use a content of about 10%. It can maintain long-lasting efficacy due to its ultra-high surface area, extremely high adsorption capacity, easy suspension, good affinity, and chemical stability. Even under rain, flushing, and hot conditions, it can remain unchanged for a long time.

Daily chemical products
Transparent colored and opaque toothpaste with white carbon black as filler and abrasive, which has good flexibility and dispersibility, smooth and soft paste, good abrasion resistance, and does not corrode the toothpaste tube body; It can maintain the stability of medicinal toothpaste. Especially with good compatibility with fluoride, it can avoid the disadvantage of insoluble salts produced by calcium salts as abrasives.

Adhesive
Used in adhesives made of natural rubber or synthetic rubber, it provides thixotropy and reinforcement, while also improving adhesion due to its stretchability, making it high-quality and cost-effective.

Anti caking agent
White carbon black can be used in some products to improve free fluidity, such as grassland fertilizers, fungicides, grinding wheel abrasives, laundry bleaches, phenolic injection molding of urotropine, plastic products of phenols and urea, manufacturing of rubber sulfur and anti caking mixtures.

Paper filling material
Using white carbon black as a paper filler can improve the ink resistance and mechanical strength of the paper, increase whiteness, and reduce unit weight. It can effectively achieve paper lightweighting, reduce production costs, and improve paper performance.

Gas phase white carbon black is one of the extremely important high-tech ultra-fine inorganic new materials. Due to its small particle size, it has a large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion performance, thermal resistance, and resistance, and has special properties. With its superior stability, reinforcement, thickening, and thixotropy, it has unique characteristics in many disciplines and fields and plays an irreplaceable role. Gas phase white carbon black, commonly known as “nano white carbon black”, is widely used in various industries as an additive, catalyst carrier, petrochemical, decolorizing agent, extinction agent, rubber reinforcement agent, plastic filling agent, ink thickener, metal soft polishing agent, insulation and thermal insulation filling agent, advanced daily cosmetics filling and spraying materials, medicine, environmental protection and other fields. And it provides a new material foundation and technological guarantee for the development of related industrial fields. Due to its unique functions in magnetism, catalysis, light absorption, thermal resistance, and melting point compared to conventional materials, it has received great attention from people.
