ふるい分けと分級 粒度分布は試料の物理的・化学的特性に大きな影響を与えます。したがって、粉体試料の粒度分布を知ることは、品質管理のなかでも重要な要素です。粒度分布が、いかに製品の品質に影響するかは、次の例でも明らかです。
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. (...)
