Journal of Rock Mechanics and Geotechnical EngineeringPolymer-modified bentonite (PMB) is much more effective at containing chemically aggressive liquids than conventional bentonite. The PMB manufacturing process typically utilizes natural, high-quality sodium bentonite (NaB) owing to its excellent ...

Reduction of Offensive Odor from Natural Rubber Using Zinc-Modified Bentonite
Advances in Materials Science and Engineering, 2018 Natural bentonite was modified with zinc ions and was used as a filler to reduce the offensive odor from raw natural rubber (NR). Characterization of filler shows the limited exchange of inherent calcium ions and the preferred adsorption of zinc ions on ...
