La distribution des tailles de particules influence les propriétés physico-chimiques des solides. Ce qui veut dire que, dans un contexte de contrôle qualité des poudres, il faut contrôler la répartition granulométrique. La qualité du produit est garantie seulement si sa répartition granulométrique est constante, comme ces exemples le montrent :
All to often, this useful method is overlooked. But if followed, these principles deliver accurate and reliable results at an affordable price.
When it comes to particle sizing, the classical technique of sieve analysis is often overlooked in favor of more modern methods. Yet, with the right equipment and proper care, sieve analysis yields accurate and reproducible results for a fraction fo the cost. As a standalone particle-sizing technique, sieing should be considered when the majority of the particles are over 75 microns. It can also be used for smaller sizes if the results are routinely verified. (...)
