摘要
研究了沙蒿籽胶与黄原胶混合体系的流变特性。结果表明,沙蒿籽胶与黄原胶具有协同增效性,不同配比的沙蒿籽胶与黄原胶混合后,其协同增效性不同,当沙蒿籽胶与黄原胶的质量比6∶4时,二者的协同增效性最高,且胶溶液符合Herschel-Bu lkey流动模型,并具有胶变性。动态流变学特性表明:混合胶溶液显示弱凝胶特性。
The rheological properties of blended system of Artemisia sphaerocephala Krasch. gum and xanthan gum were studied. The results showed that the blended system of A. sphaerocephala gum and xanthan gum had synergistic interaction. The synergistic interaction was different with different proportions of the two gums. When the mass ratio of A. sphaerocephala gum to xanthan gum was 6 ： 4, the synergistic interaction was the strongest. The rheological properties followed Herschel-Bulkey model and it had rheopexy. Blended gum solutions of A. sphaerocephala gum and xanthan gum exhibited typical ＂ weak gel＂ properties through small strain oscillatory measurements.
