Analysis of flowability and dynamic viscoelastic of LBG /SA solution

The flowability and dynamic viscoelasticity were investigated for different ratio of LBG ∶ SA under the condition of 25℃.The results showed that complex was pseudoplastic fluid, the greater the proportion of the SA, the better correlation to the rheology of power- law model.In response to external strain stimuli, LBG played a major role in the energy storage and the energy corresponding to the flow loss was mainly caused by the solution SA.The storage modulus ( G') of complex system increases with increasing frequency in the sweep range, indicating that the greater the frequency, the more energy storage. The higher the temperature, the lower the viscosity of the complex, and the larger the ratio of LBG, the higher the value of the complex viscosity.
