Predicting the Occurrence of Sticking during Tablet Production by Shear Testing of a Pharmaceutical Powder
Predicting the Occurrence of Sticking during Tablet Production by Shear Testing of a Pharmaceutical Powder
A larger SI indicates a greater likelihood that sticking will occur.
Defining SI for Assessing Adhesion of Powder to the Punch
One cause of sticking is that when a powder is being compacted, the adhesive force between powder particles of the tablet and the punch surface exceeds the adhesive forces of powder particles within the tablet. Φp represents the frictional force acting between…
