GB/T 21868.3-2008 "Pigments and extenders—Methods of dispersion for assessment of dispersion characteristics—Part 3: Dispersion using a high-speed impeller mill" specifies the operational method for dispersing pigments using a high-speed impeller mill, which is applicable to the dispersion of medium- and low-viscosity pigment pastes. It defines parameters such as the rotational speed of the impeller, mixing duration, and the method of material addition, achieving pigment dispersion through high-speed shear. The testing requires equipment such as a high-speed impeller mill, a tachometer, and a constant-temperature water bath, providing an efficient stirring and dispersion solution for the assessment of dispersion characteristics.
