Title: Flow properties of coagulated colloidal suspensions
Abstract: The basic shear diagram (shear stress versus shear rate) for coagulated colloidal suspensions is plastic-pseudoplastic. This flow curve has three definable experimental parameters: the Bingham Yield Value, the shear rate at which the linear portion of the flow curve begins, and the gradient of the linear part of the flow curve. The relationships between the experimental flow parameters and the colloidal parameters (volume fraction, particle size, and interactive forces) are examined. Ten such relationships can be established and these can be used to test the validity of possible models of the flow of coagulated suspensions. For some systems there appears to be a critical radius at which a change occurs in the dependence of the flow parameters on the particle size.
