| Abstract: In the processes of modification from natural calcium bentonite into sodium bentonite, or from sodium bentonite into organic bentonite, mixing and extrusion has an important function in improving distribution of bentonite. By shearing action and broken bond, the average diameter of bentonite particle size is availably reduced, and the average quantity of its ξ-potential is increased. |
