Latest Patents

Mizoguchi's latest patents include a "Continuous Dispersing Apparatus" and a "Method for Preparing a Pigment Composition." The Continuous Dispersing Apparatus is designed to enhance the dispersion of pulverizing media within a vessel. It features stirring vanes that prevent the discharge of coarse pigment particles while allowing dispersed material to pass through. The apparatus includes a rotating disc and a partition that divides the vessel into multiple chambers, each equipped with stirring devices. The Method for Preparing a Pigment Composition involves charging pigment, water, and a water-insoluble resin into a mill. This method mills the mixture at a temperature below the resin's softening point, resulting in a fine powder that is uniformly dispersed throughout the resin.
