The Advantages of Calcined Kaolin in Paper Manufacturing

Calcined kaolin is derived from natural kaolin clay through a high-temperature calcination process. This treatment drives off chemically bound water, resulting in a material with a more porous structure and altered crystal morphology. These changes contribute to several key benefits when used in paper production:

• Enhanced Brightness and Whiteness: Our calcined kaolin powder boasts a high whiteness of 94-95%, which significantly contributes to the overall brightness and opacity of paper. This allows for reduced use of expensive optical brightening agents and pigments.
• Improved Printability: The fine, uniform particle size and surface properties of calcined kaolin create a smoother paper surface. This enhances ink holdout, reduces feathering, and leads to sharper, clearer printed images.
• Controlled Opacity: Calcined kaolin acts as an effective filler, increasing the opacity of the paper. This is crucial for preventing show-through, especially in lightweight papers or those intended for double-sided printing.
• Better Ink Absorption: The porous nature of calcined kaolin can help control ink penetration, ensuring that inks stay on the surface for a crisp print, rather than bleeding into the paper.
• Gloss and Smoothness: In coated papers, calcined kaolin contributes to a smooth surface finish and can enhance gloss levels, making the paper more aesthetically pleasing for various applications, from magazines to packaging.
