摘要:
The present invention provides production methods for aqueous dispersion slurry of inorganic particles which are so stable as not to increase in viscosity, gel or sediment even if stored for a long time and whose average particle diameter is 0.01 to 2 µm. As such production method, 2 production methods are available:
A production method (A) having a preliminary dispersion process in which the inorganic particles are added to ad dispersed in an aqueous medium and a main dispersion process in which dispersed slurry out of the preliminary dispersion process are collided with each other under a pressure of 100 to 3,000 kg/cm 2 ; and
A production method (B) in which the inorganic particles are added to an aqueous medium within a kneading tank of a kneader in which mixing blades rotate around respective subsidiary spindles and the subsidiary spindles revolves around a spindle and dispersed at a solid concentration of 30 to 70wt%.
