Pigments and extenders - Methods of dispersion for assessment of dispersion characteristics - Part 5: Dispersion using an automatic muller

GB/T 21868.5-2008 "Pigments and extenders - Methods of dispersion for assessment of dispersion characteristics - Part 5: Dispersion using an automatic muller" specifies the operational procedures for dispersing pigments with an automatic muller, which is suitable for small-batch pigment dispersion. It defines parameters such as grinding pressure, rotation speed, and number of grinding cycles for the muller, achieving pigment dispersion through the compression of grinding plates. The testing requires instruments such as an automatic muller, thickness gauge, and analytical balance, providing a standardized operation for assessing pigment dispersion characteristics at the laboratory scale.
