Summary of the most common basic knowledge differences between carbon black and pigment carbon black and silica manufacturers' products

Carbon black is a quasi-graphite structure substance composed of approximately spherical colloidal particles formed by incomplete combustion or thermal cracking of hydrocarbon compounds (mainly petroleum derivatives). It exists in the form of aggregates and appears as pure black powder or granules. The particle size, structure, and surface activity of the product vary greatly depending on the raw materials and production process. Carbon black is insoluble in water, has acidic and alkaline properties, and produces carbon dioxide after combustion. The main component of carbon black is carbon, and it also contains trace amounts of hydrogen, oxygen, sulfur, ash, tar, and moisture.

What are the differences between the specific surface area and packing density of silicon dioxide produced by silicon dioxide manufacturers?

What are the differences between the specific surface area and bulk density of silica produced by silica manufacturers? The bulk density of silica is grams/liter. The weight of a liter of volume, for example, 200 grams per liter, means that the weight of silica per liter is 200 grams; the specific surface area BET of silica is the total area of the unit mass of material, in square meters/gram. For example, 170 square meters per gram means that the total surface area of silica per gram of weight is 170 square meters. Particle sizes range from 10nm to hundreds of micrometers; The properties are different, and the uses are also different.

What are the uses of silica after it is produced by silica manufacturers?

What are the uses of silica produced by silica manufacturers? Uses editing: Due to a series of superior properties of silica products, it can be widely used in many fields. Rubber products: Silica is used in colored rubber products to replace carbon black for reinforcement, meeting the needs of white or translucent products. Silica also has super adhesion, tear resistance, and heat 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, and radial tires. Agricultural chemical products: In agricultural chemical products, such as pesticides, high-efficiency foliar fertilizers, etc., white carbon black is used as a carrier or diluent, disintegrant. As a disintegrant, it can improve the suspension rate when used in water-dispersible granules (WDG), and the recommended usage is about 10%. It can maintain long-lasting efficacy because its ultra-high surface area has extremely high adsorption, is easy to suspend, and has good affinity and chemical stability. It can remain unchanged for a long time even in rain, washing, and hot conditions. Daily chemical products: Transparent colored and opaque toothpastes using silica as filler and abrasive. These toothpastes have good flexibility, dispersibility, smooth and soft paste, good abrasiveness, and do not abrade the toothpaste tube; it can maintain the stability of the medicinal properties of medicinal toothpastes. In particular, it has good compatibility with fluorides, which can avoid the drawbacks of calcium salts as abrasives producing insoluble salts. Cementing agent: Used in adhesives made of natural rubber or synthetic rubber, it provides thixotropy and reinforcement. At the same time, its extensibility can also improve adhesion, and it is of high quality and low price. Anti-caking agent: Silica can be used in some products to improve free flow, such as lawn fertilizers, fungicides, grinding wheel abrasives, laundry bleach, phenolic injection molding urotropine, plastic products of phenol and urea, manufacturing rubber sulfur, and anti-caking mixtures. Paper filler: Using white carbon black as 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 lightweighting, reduce production costs, and improve paper performance. In addition, it can also be used in fire extinguishing agents, feed, cosmetics, matting agents, pigments, paints and many other industries.
