Title: Innovations of Peter James Malden
Introduction
Peter James Malden is a notable inventor based in Lostwithiel, GB. He has made significant contributions to the field of materials science, particularly in the development of alkaline earth metal carbonates and the treatment of clay mineral pigments. With a total of 3 patents, his work has implications in various industrial applications.
Latest Patents
One of Malden's latest patents involves the production of a precipitated alkaline earth metal carbonate. This process includes calcining raw alkaline earth metal carbonate, such as calcium carbonate, under specific conditions to drive off chemically combined carbon dioxide. The resulting oxide is then slaked in water to form a suspension of the corresponding alkaline earth metal hydroxide. This suspension is carbonated with substantially pure carbon dioxide in the presence of a dithionite bleaching reagent, leading to a precipitate of an alkaline earth metal carbonate that boasts increased brightness and purity. The precipitate can be separated from the aqueous medium through filtration.
Another significant patent focuses on improving the rheological properties of an aqueous suspension of clay minerals. This process involves mixing the suspension with a water-soluble organic compound that has multiple basic groups and a molecular weight not exceeding 1,000. The treated clay minerals can be utilized as pigments in paper coating compositions, enhancing the quality and performance of the final product.
