摘要

Abstract

Hydroxypropyl xanthan gum (HXG) was prepared from xanthan gum (XG) and propylene oxide under alkaline condition. Rheological and drag reduction properties of different concentrations of aqueous HXG and XG solution were studied. The micro-structure network of HXG and XG solutions was investigated by Cryo-FESEM. The results showed that HXG and XG solutions could exhibit shear thinning property. The apparent viscosity of 6 g·L

-1

HXG solution was 1.25 times more than that of 6 g·L

-1

XG solution. The storage modulus

' and the loss modulus

" of HXG solutions were greater than those of XG solutions

and thixotropic and viscoelastic properties were more significant in HXG solutions. The HXG and XG solutions reduced the pressure drop of straight pipe

and themaximumdrag reduction of 1 g·L

-1

HXG and XG in smooth tube reached 72.8% and 68.1%

respectively. Drag reduction rate was increased as the concentration increased. The HXG solution may become a new polymeric drag reducer.
