Relationship between colloidal value and viscosity of Benton

The colloid value is one of the technical indexes to identify the grade of bentonite and evaluate the quality value of bentonite. The higher the gum value, the higher the viscosity. The dispersion and hydration degree of bentonite colloid value is the comprehensive performance of dispersive, hydrophilic and expansive bentonite used in food. Its size is closely related to the grade of bentonite ore and montmorillonite content. For example, the price of Na bentonite is higher than that of Ca bentonite, and the more montmorillonite there is in the same type of bentonite, the higher the colloid value is, the higher the viscosity is. Therefore, colloidal value is one of the technical indexes to identify the type of bentonite ore and evaluate the quality of bentonite.
