B) type of carrier or dispersion medium
In some media, the surface properties of carbon black have a great influence on the difficulty of dispersion.
The high content of surface oxidized carbon black is much easier to disperse in the substrate, while the surface containing carbon black is relatively difficult.
C) the dispersing equipment used
The particle size is larger, the structure is higher, and the surface is more easily dispersed when the oxygen content is high, but it is also affected by the process and equipment.
The same quality of carbon black, good dispersion, ink is not only better, small screen residue, and blackness, coloring power, gloss and fluidity will become good, on the contrary is not ideal.
