PH value and viscosity of Sodium Carboxymethyl Cellulose solution
With PH value 6.5-9.0, viscosity of Sodium Carboxymethyl Cellulose solution is highest and most stable. When PH value is within 6.0-11.0, the viscosity has no big change. With PH value of over 11.5, the viscosity of medium and high viscosity Sodium Carboxymethyl Cellulose solution fall sharply, and it has small effect for low viscosity. Solid separates out from Sodium Carboxymethyl Cellulose solution with PH value under 2.
