Title: Experimental Research of Rheological Properties of Xanthan Gum
Abstract: Rheological characteristics of different xanthan gum solutions are studied.The regressions between consistency index K,flow behaviour index n and concentration of xanthan gum Cp are also investigated. The results show that,the properties of xanthan gum solution are considered to be Newtonian fluid as its concentration is lower;however,its properties can be described as pseudoplastic fluid with increase of the concentration.K,n can be described as the function of Xanthan gum's concentration respectively,the correlations are as follows: 0Cp≤30 g/L,K=1.128C1.572p;0Cp≤8 g/L,n=0.485-0.16lnCp;8g/LCp≤30 g/L,n=0.075+0.04lnCp.
