Pigment particle size drawdown

The pigment particle size drawdown bar spreads a pigment slurry into a thin film in a wedge-shaped groove, allowing observation of the streak positions where particles become visible. By referencing the scale, the particle size distribution is determined. It is used for quality control of pigments in the coatings and ink industries, reflecting properties such as dispersibility and hiding power.
Selection
When selecting, consider that the scraper material should be corrosion-resistant, the scale accuracy should match the testing requirements, and the groove depth range should cover the particle size of the samples to be tested. Clean promptly after use to avoid scratching the surface, and regularly calibrate the scale accuracy with a standard plate.
