Description

TECHNICAL FIELD

[0002] Carbon black is a kind of amorphous carbon, light, loose and very fine black powder, with very large surface area, which is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air. The structure of carbon black is represented by the degree of chain or grape-like aggregation between carbon black particles. The oil absorption value is commonly used to represent the structure, the larger the oil absorption value, the higher the carbon black structure, and it is not easy to damage the space network channel. Carbon black is divided into reinforcing carbon black, conductive carbon black, wear-resistant carbon black, etc. according to its performance, due to its high conductivity, high wear resistance, high strength and other characteristics, it has been widely used in many fields, such as rubber, plastic, ink, paint, cosmetics, etc. In order to meet market demand, carbon black production has become an important industrial field. Conductive carbon black is a kind of carbon black with low resistance or high resistance, which can give the product conductive or anti-static effect, and its characteristics are small particle size, large specific surface area, high structure, clean surface (few compounds), etc.

[0003] The production process of carbon black needs a reaction furnace, which usually adopts two forms of coal-fired reaction furnace and gas-fired reaction furnace. However, since the coal-fired reaction furnace will produce a large amount of carbon dioxide and other harmful substances, causing serious pollution to the environment, the gas-fired reaction furnace has gradually become the mainstream form of carbon black production. With the development of science and technology, high-conductivity carbon black is more and more widely used, and the requirements for carbon black production are also higher and higher.
