Carbon black dispersion is a critical process in many industrial productions. However, carbon black particles tend to agglomerate and are difficult to disperse uniformly, leading to reduced coloring power, uneven gloss, and unstable performance. These issues directly impact production efficiency and end-product quality.

To address these challenges, Chemi Tech has developed a series of high-performance dispersants that improve dispersion from a mechanistic perspective. The solutions are based on systematic research on the surface properties of carbon black and dispersion media. Through the synergistic effect of anchoring groups and solvating chain segments, they significantly reduce interfacial energy and prevent particle re-agglomeration, resulting in a stable and homogeneous dispersion system.
The implementation involves four key steps: First, analyze the polarity of the system and the characteristics of the carbon black to select the most suitable dispersant type. Second, determine the optimal dosage of the dispersant, typically recommending phased addition to maximize dispersion efficiency. Third, combine mechanical dispersion with chemical action to achieve full deagglomeration through shear force and chemical synergy. Finally, conduct stability tests to evaluate dispersion effectiveness, ensuring no re-coagulation or sedimentation during long-term storage.
A rubber product manufacturer once faced issues with surface pitting due to uneven carbon black dispersion. After switching to a customized dispersant from Chemi Tech, the fineness of carbon black dispersion improved significantly, product surface smoothness was enhanced, and production efficiency increased by approximately 20%, resolving long-standing quality fluctuations.
Chemi Tech is committed to providing scientific and reliable dispersion solutions to help enterprises enhance product quality and production efficiency.
