Ashapura Pilogel Bentonite Powder in Bangladesh
Ashapura Pilogel Bentonite Powder is a premium product manufactured by Ashapura Group India Private Company. It is a high-quality natural sodium-based bentonite designed for various underground construction needs.
About Bentonite: Technical Specifications
Ashapura Pilogel Bentonite Powder is a natural clay belonging to the smectite family. Its versatility comes from the montmorillonite platelet structure, making it act effectively as both a mineral and a chemical agent.
The “Club Sandwich” Structure:
The chemistry of bentonite is unique. The individual platelets can be visualized as a “club sandwich”:
-
Tetrahedral Silicon Oxide Layer: Some silicon is replaced with trivalent cations.
-
Octahedral Aluminum Oxide Layer: Sandwiched in the middle, with some aluminum replaced by divalent cations.
-
Hydroxide Group Edge: Allows the formation of thixotropic gels in water.
How it Works:
Metal replacements within the structure create charge imbalances on the surface. These are countered by cations bound to the surface. When dispersed in water, the lattice moisture and charge interactions allow the powder to form a high-grade support fluid.
Key Features & Benefits
When dispersed in water, Ashapura Pilogel Bentonite achieves excellent rheological characteristics, making it ideal for challenging soil conditions.
