DEPENDENCE OF POWER-LAW PARAMETERS ON POLYSACCHARIDE CONCENTRATION USING METHYLAN

The dependency of rheological parameters changes as a function of poly saccharide concentration. The power-law parameters of methylan solutio ns, consistency index (K) and flow behavior index (n), can be expresse d according to methylan concentration (P) using the empirical power-ty pe correlation K = AP(B) and the linear relationship n = C - D log P. The dependence of power-law parameters on polysaccharide concentration can be used to determine the transition concentration at which rheolo gical properties change from dilute to concentrated solution behavior.
