Croscarmellose Sodium GettyImages-1286727998

The processability of powders is dependent on factors such as cohesion strength and flow function. Powder rheology can be used to measure these properties and aid in hopper design, selection of flow rates, and quality control. Carboxymethyl cellulose powder is a hygroscopic material used in a variety of applications. In this study, the impact of moisture content on cohesion strength is measured using a shear cell accessory. It was found that as moisture content increases, cohesion strength also increases, demonstrating the importance of controlling humidity during processing.
