ABSTRACT:
The invention relates to a method for producing nitrocellulose-based carbon black in the form of chips. The recipe constituents are blended into a mixture and converted at an elevated temperature into a dispersion in a suitable device which achieves the desired degree of kneading such as a kneading machine or roller die extruder. The dispersion is then calendered into a film, the film is cooled and crushed into chips. The carbon black concentrates can be used as pigmentation agents for lacquers, paints and printing inks.
