Problems solved by technology

[0012] This liquid-phase oxidation method is realized by introducing the post-treatment process of the final product of carbon black. Since it is a batch type, it reduces the stability of the process and the uniformity of the product, which eventually leads to the problem of lower yield.

Abstract

The present invention relates to a carbon black production apparatus which is provided with a reactor capable of uniformly oxidizing carbon black, thereby continuously surface-treating carbon black while producing raw material carbon black.

Description

technical field [0001] The present invention relates to a carbon black preparation device. The above carbon black preparation device is provided with a reactor capable of performing uniform oxidation treatment on carbon black, so that the carbon black can be continuously surface treated while preparing raw carbon black. Background technique [0002] Carbon black refers to an aggregate of very fine spherical particles obtained by incomplete combustion of compounds containing various hydrocarbons or carbon. Carbon black forms primary particles in the reaction furnace, and these primary particles fuse with each other to form primary aggregates in the shape of grape bunches. In this way, the degree of development of primary aggregates is called structure (Structure). [0003] As a black colorant, high-color carbon black is mainly used in industrial paints, coatings, colorants for plastics and fibers, various printed matter and newspaper printing inks, etc. Also, high-color car...
