Application of White Carbon Black in Ink Jul 01, 2024

01 Enhancing Viscosity and Consistency

Controlling the viscosity and consistency of ink is crucial during the ink preparation process. Due to its tiny particle size and large specific surface area, white carbon black forms an effective filling network in the ink, increasing the internal friction of the ink, thus effectively enhancing its viscosity and consistency. This plays a significant role in preventing ink separation during storage and use, ensuring the stability of the ink during the printing process.

02 Improving Sedimentation Resistance

During long-term storage, pigments and fillers in ink may settle, affecting the uniformity and printing quality of the ink. Amorphous Precipitated Silica effectively improves the sedimentation resistance of ink. After dispersing in ink, white carbon black particles form a stable three-dimensional network structure, which hinders the settling of pigment and filler particles, maintaining the uniformity of the ink.

03 Enhancing Abrasion Resistance and Scratch Resistance

During high-speed printing, the abrasion resistance and scratch resistance of ink are important factors that ensure the quality of printed products. The application of Precipitated Silica in ink can significantly improve the abrasion resistance and scratch resistance of printed products. This is due to the good hardness and strength of white carbon black, which can form a solid film layer after the ink dries, reducing wear and scratches on the surface of printed products.

04 Adjusting Glossiness

The glossiness of ink directly affects the appearance and texture of printed products. By controlling the addition amount and dispersion degree of white carbon black, the glossiness of ink can be effectively adjusted. A higher addition amount or poor dispersion of white carbon black can lead to a decrease in the glossiness of ink, while an appropriate amount and good dispersion of white carbon black can maintain a certain glossiness of ink, meeting the needs of different printed products.

05 Improving Printing Adaptability

Printing adaptability refers to the stability and applicability of ink under different printing conditions. The addition of Silicon Dioxide Provide can improve the rheological properties of ink, making it more suitable for different types of printing processes, such as screen printing, relief printing, and flexographic printing. In addition, white carbon black can also help ink achieve better adhesion and coverage on different printing media.
