Study on the Influential Factors of Shear Degradation of Polymer

Abstract:

In order to study the regularity of shear degradation of polymer solution, the artificial core is used to simulate the flow of polymer formation^[1]. The influence of mass concentration, molecular weight and shear rate on the rheological of polymer solution is studied. And the stability of the polymer solution after degradation were analyzed through method of indoor simulation experiment Research shows that Polymer solution is degraded after shearing , the viscosity reduced and it will not rebound with the passage of time. When the solution was sheared through the porous medium, degradation rate increases with the increase of shear rate. Also it can be seen, in the case of the same concentration, the degradation rate increases with the increase of relative molecular mass. In the case of the same relative molecular mass, the degradation rate increases with the increase of the mass concentration.
