| titleOfInvention | New processing procedure for transforming previously unusable clays and kaolin clays to low viscosity pigment |
| abstract | An improved process for transforming clays that cannot be utilized in commercial pigment production to low-viscosity pigment for commercial application is described whereby a treated clay is produced having a reduced viscosity as compared to the initial clay when compared at equivalent solids content. The process comprises the steps of: drying the clay; mixing the dried clay with an aqueous solution of an alkali metal salt wherein the alkali metal salt is selected from the group consisting of lithium, potassium, rubidium and cesium salts; extruding the material obtained from alkali metal salt treatment; heat-treating the extruded material and high-shear blunging of the heat-treated material. Typically, a high viscosity clay that has been treated with this five-step procedure will exhibit a viscosity that is about 10 % to about 20 % of the viscosity of the starting clay. |
