Evaluation of Pigment Dispersion by Measuring Particle Size Distribution

Abstract

Needless to say, controling the pigment dispersion in paint manufacturing process is one of the most important point.
And checking the upper particle size with a grinding gauge has been the most popular and conventional method for measuring the pigment dispersion level.
According to the recent and quick development of computor system, measuring equipments of particle distribution are also getting pretty reasonable progress and some of these might make it possible to evaluate the pigment dispersion level by measuring the particle distribution without thinning its enamel sample.
As a newly modified and combined evaluation method for pigment dispersion, measuring particle distribution was studied in our laboratory by the application of image processor system.
Based on our experience, studying and results, measuring the particle distribution through image processor system might be positively recommended by the author for a very reliable and practical evaluation method of the pigment dispersion level.
