The role of carbon black in paper making

There are three main roles in paper making:

First, in the field of paper pulp, it mainly increase the strength, toughness and folding resistance of the paper. At the same time, it can increase the processing operation process and the stability of the pulp during the forming of the paper, so that the pulp has superior processability. It also provides anti-subsidence properties to prevent the delamination of the pulp filler and resin system, and to prevent occurrence precipitation due to the heavy packing ratio.

Second, in the paper layer, play two roles: Extinction performance and Provide superior ink absorption performance.

Third, in the paper making defoamer, it mainly play the role of thickening and anti-sedimentation

The degree of coloration is based on the formula. Carbon black is just a coloring agent in paper making. When you purchase the carbon black, you can ask the carbon black supplier to provide you with high blackness or tinting strength. Except this, you also can improve the hue of carbon black by adding chemical raw materials. However the cost is a bit high.
