Title: The Innovative Journey of Inventor Alan J. Brown
Introduction
Alan J. Brown is a distinguished inventor based in Milledgeville, GA, known for his contributions to the field of mineral pigments for coatings. With an impressive portfolio of 15 patents, he has significantly advanced the methods and materials used in the production of paper and paperboard, showcasing his innovative approach to problem-solving in industrial applications.
Latest Patents
Among Alan's latest inventions are two notable patents. The first patent revolves around a method for producing structured calcium carbonate pigments for coating paper. This innovative process involves the creation of an aqueous slurry of anionically dispersed calcium carbonate particles at a concentration of 1 to 30 percent solids. By adding a low-molecular-weight cationically charged aggregating agent, fine and ultra-fine particles are selectively aggregated, resulting in larger aggregates with minimized colloidal particles. These aggregates, characterized by a reduced net charge, are further processed to increase solids content above 60 percent by weight, thereby enhancing their utility in coating applications.
The second patent addresses the aggregation of fine and ultrafine particles in mineral pigment slurries to form aggregates with a labyrinth of internal voids. These structures function as light scattering centers, improving the bulk and opacity of the final paper products. Such aggregates, created using small quantities of cationic or anionic polymers, are optimized for retention in fiber webs through filtration and adsorption methods, ultimately enhancing the optical properties and surface quality of coated paper and paperboard.
