Silica is a general term for white powdered X-ray amorphous silicic acid and silicate products. It mainly refers to precipitated silica, fumed silica and ultrafine silica gel, as well as powdered synthetic silicic acid. Aluminum and calcium silicate. Silica is a porous substance whose composition can be represented by SiO2·nH2O, wherein nH2O exists in the form of a surface hydroxyl group. Soluble in caustic and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustible, odorless, odorless, and has good electrical insulation.

Daily chemical products
Transparent color and opaque toothpaste with white carbon black as filler and abrasive. This type of toothpaste has good flexibility and dispersibility. The paste is smooth, soft and abrasive. It does not abrade the toothpaste tube. It can keep the drug toothpaste. The drug is stable. In particular, it has good compatibility with fluoride, which can avoid the disadvantages of calcium salts as abrasives to produce insoluble salts.

Anti-caking agent
White carbon black can be used in some products to improve free-flowing properties such as grass fertilizers, fungicides, abrasive grinding agents, laundry bleaches, phenolic injection urotropine, phenol and urea plastics, rubber sulphur and anti-knot Block mixture.

Paper filler
The use of white carbon black as a paper filler can improve the paper's resistance to ink penetration and mechanical strength, increase whiteness and reduce unit weight. It can effectively achieve paper weight reduction, reduce production costs, and improve paper performance.
It can also be used in many industries such as fire-fighting agents, feeds, cosmetics, matting agents, pigments, and paints.

rubber products
White carbon black is used in color rubber products to reinforce carbon black to meet the needs of white or translucent products. White carbon black also has superior adhesion, tear resistance and heat and aging resistance, so it can replace some carbon black in black rubber products to obtain high quality rubber products, such as off-road tires, engineering tires, Meridian tires, etc.

Agricultural chemicals
In agricultural chemicals, such as pesticides, high-efficiency spray fertilizers, the use of silica as a carrier or diluent, disintegrant, disintegrant used in water-dispersible granules wdg can increase the suspension rate, it is recommended to use 10 %about. It maintains long-lasting effectiveness because of its extremely high surface area, high adsorption capacity, easy suspension, good affinity and chemical stability. Even in rain, wash and hot conditions, it will remain unchanged for a long time.
