How do I modify calcium carbonate powder?

Calcium carbonate (CaCO₃) powder modification involves various techniques aimed at improving its properties for use in different industrial applications. These modifications can enhance characteristics such as dispersibility, hydrophobicity, particle size, compatibility with various matrices, and specific functional properties. Here are some common methods of modifying calcium carbonate powder

Grinding and milling techniques are used to reduce the particle size of calcium carbonate.

Commonly used grinding equipment include Raymond mill, ultrafine mill…They can reduce the fineness of calcium carbonate powder to 50-3000 mesh.

Fine particles can improve the performance of the powder in applications such as:

l Paints and Coatings: Providing better opacity, whiteness, and smooth texture.

l Plastics and Polymers: Enhancing mechanical properties and surface finish.
