'10 ways to control rheology by changing particle properties' is the latest addition to Malvern Panalytical' INFORM series of white papers, which are designed to provide advice on material characterization issues. Freely downloadable from the Malvern Panalytical website, this new document guides the reader through some of the fundamental properties of dispersed systems and demonstrates how these affect its rheology. A variety of examples illustrates the effects on rheology of changing particle size, size distribution, shape and zeta potential, alone and in combination. http://www.malvern.com/control_rheology
Many materials used today are disperse systems where one substance, often a particulate, is dispersed in another phase. Examples are common in areas as diverse as adhesives, agrochemicals, cement, ceramics, colloids, cosmetics and personal care formulations, food and drink, mining and mineral slurries, paints, inks and surface coatings, pharmaceuticals and polymer systems. The physical properties of the dispersed particles - average particle size, size distribution, zeta potential or charge on the particles, and particle shape - all influence bulk material properties such as rheology. Therefore the rheology of a dispersed system can be controlled through the measurement and manipulation of key parameters.
