In the process of upgrading the calcium carbonate industry toward high-end development, purity and impurity control capabilities serve as the core technical thresholds. These capabilities differentiate product grades and determine application boundaries. General industrial-grade calcium carbonate only needs to meet basic filling requirements. It also maintains a higher tolerance for trace impurities. In contrast, high-purity […]

Calcium carbonate, as the most abundant and lowest-cost inorganic powder filler, naturally exhibits strong hydrophilicity on its surface. However, it has poor compatibility with organic polymer matrices such as plastics, rubber, and coatings. Under high loading conditions, it tends to suffer from particle agglomeration, weak interfacial bonding, and reduced mechanical properties of final products. These

Calcium Carbonate Filler for Plastics (including both ground calcium carbonate and precipitated calcium carbonate) is currently the most widely used and highest-volume inorganic filler in the plastics industry. It is not merely a “supporting-role” filler, but rather a “performance modifier” that fine-tunes the properties of modified plastics. The key functions of calcium carbonate in plastics

In the production of ground calcium carbonate (GCC), grinding equipment is undoubtedly the core of the entire production line. However, many clients who are new to the calcium carbonate processing industry often have a question when selecting equipment. Since there is already a mill, why is it necessary to additionally equip it with an air
