1 Scope

This standard specifies the method for determination of coatings and related products filler particle size distribution. This method is applicable to the determination of the Stokes diameter range greater than 2μm particle mass fraction of particles. Note. In any case, all the results obtained by this method with the results of other methods are not comparable.

2 principle of the method

Depending on the particle size of particles of different settling velocity principle, within a specific time with a dropper Anderson sampler, dried and weighed, and Different calculation (Stokes diameter) mass fraction of the particle size of the particles. The method is as follows. first configure aqueous samples and the sample is added a dispersing agent, after reaching the sediments to determine the depth, at a particular time with Anderson dropper to sample quality measurement dried sediment samples and calculate the mass fraction.
