刺槐豆胶(LBG)/海藻酸钠(SA)复合体系的流动性和动态粘弹性分析

Analysis of flowability and dynamic viscoelastic of LBG /SA solution

  • 摘要: 25℃条件下分析了不同配比LBG/SA复合体系的流动性和动态粘弹性。结果表明:复合体系是假塑性流体,且SA的比例越大,在剪切条件下越符合流变学的幂率模型;复合体系响应外界应变刺激的过程中,LBG起主要的能量储存作用,相应的损耗的能量主要是SA溶液的流动造成的;在频率扫描范围内,复配体系储能模量随着频率的增大而增大,表明频率越大,能量储存越多;温度越高,复合粘度值越低,且LBG比例越大,复合粘度值越高。 

     

    Abstract: 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.
