When it comes to carbon black and white carbon black, many people wonder whether they are the same substance. In fact, they are two different substances. White carbon black is not a type of carbon black. Although their names are similar, the difference between carbon black and white carbon black is obvious. Let’s analyze it from the following aspects:
The difference between the two
● In aspect of composition
Carbon black is a type of amorphous carbon, usually in the form of black powder. It is a product from incomplete combustion or pyrolysis of carbon-containing materials, such as: coal and natural gas, under the condition of insufficient air. Its main component is carbon, with a small amount of oxygen, hydrogen and sulfur.
White carbon black is the general name for white powdery X-ray amorphous silicic acid and silicate products. Its mian component is silicon dioxide, also called hydrated silicon dioxide. It is in the form of white powder, and is an inorganic silicon compound.
● In aspect of characteristics
Carbon black has the characteristics of high specific surface area, high conductivity, high wear resistance and high chemical stability.
White carbon black has the characteristics of porosity, hygroscopicity, non-flammability, high activity and electrical insulation.
● In aspect of application
Carbon black
Carbon black is the most important reinforcing agent and filler in rubber industry. It can significantly improve the strength, hardness and wear resistance of rubber, thereby extending the service life of rubber products. For example, it is essential in the manufacture of various types of tires, such as car tires and aircraft tires.
It is the main pigment of black printing ink, it can endow the ink clear and vivid colors, with good hiding power, durability and dispersibility.
In addition, carbon black also has application in industries of plastics, paints and wires and cables, etc.
White carbon black
White carbon black can act as an important reinforcing filler in rubber industry, too. It can provide good mechanical property and anti-aging property for rubber products, and reduce production costs.
It can be used as a whitening agent and thickener in coatings industry to make the coating smoother and more uniform, with better hiding power and stain resistance.
In cosmetics industry, white carbon black can improve the fineness, stability and glossiness of cosmetics, as well as regulating skin oil secretion and improving skin texture.
Additionally, it can also be used as preservative and high-efficiency bactericide for food packaging bags, and it also plays a purifying role in the production of alcoholic beverages.
In summary, carbon black and white carbon black have different characteristics and application. In practical applications, they can be selected according to actual conditions. At the same time, in order to improve their use value, they usually need to be crushed and ground before application to obtain the required particle size and performance. Air classifier mill is suitable for the grinding of these two materials, with high efficiency and low energy consumption.
