Many friends know that white silica powder has a common name called white carbon black, but do you know the reason for this name?

The relationship between white carbon black and carbon black

Before understanding the white carbon black "WhiteCarbonBlack", we should learn about the carbon black "CarbonBlack" which is closely related to the source of its name.

People have mastered the smoke-burning ink-making technology more than 3000 years ago, but the development of carbon black production technology has been slow for a long time. It was not until 1872 that the world's first large-scale production of carbon black industry appeared, and at the same time it produced "CarbonBlack" The term "black)" is the beginning of the modern carbon black industry. In 1912, the British Mottee discovered the reinforcing effect of carbon black on rubber, especially after significantly improving the wear resistance of tires. Since then, the demand for carbon black has grown rapidly and has gradually become an indispensable raw material for the rubber industry.

Carbon black has been used as a reinforcing material in the rubber industry for more than a century

During the First World War, due to the shortage of energy materials for the production of carbon black, Germany began to use white silica produced by the precipitation method to replace carbon black, and white amorphous silica was obtained because of its physical properties and uses similar to carbon black. Name white carbon black (WhiteCarbonBlack). Later, due to the rapid development of the automobile and its transportation industry, the increase in the price of raw materials for carbon black production, and the requirements for energy saving and emission reduction, white carbon black has become a leader in reinforcing materials in the rubber industry. At present, the use of white carbon black in colored rubber products can completely replace carbon black for reinforcement and meet the needs of white or translucent products.
