Pure calcium carbonate, owing to its strong hydrophilicity, readily agglomerates in organic matrices such as plastics and rubbers, thereby degrading the performance of the final products. To address this challenge, surface coating modification using a honeycomb mill has become the industry’s mainstream approach. The core of the honeycomb mill lies in its distinctive… “ Honeycomb-shaped ” Internal structure: This design can generate countless microscopic high-shear zones in an extremely short time, forcibly and uniformly dispersing coating agents—such as stearic acid or silane coupling agents—over the surface of each calcium carbonate particle.

Compared with conventional agitated tanks, the honeycomb mill addresses the common issues encountered during the modification process. “ Uneven packaging ” and “ Local excess ” Problem: Through high-frequency dispersion and kneading, the coating layer can adhere tightly and uniformly to the particle surface, completely transforming calcium carbonate from hydrophilic to lipophilic. This high‑quality surface modification not only significantly enhances the filler’s dispersibility within the polymer matrix but also strengthens interfacial adhesion, enabling the final product to achieve superior mechanical strength and weather resistance while maintaining low cost.
