Industrial Sodium Bentonite Powder – Drilling and Sealing Grade
Bentonite Powder is a natural clay mineral of montmorillonite base with high water retention capacity. Formed by the gradual weathering of volcanic ash, this specialty raw material offers versatile solutions across engineering, environmental, and industrial projects. Key Properties: High Swelling (Expansion): Significantly increases in volume upon contact with water. Low Permeability: Provides excellent water impermeability. Strong Adsorption: Retains heavy metals and contaminants at high rates. Plasticity: Easily moldable with strong binding characteristics. Applications: Sealing (GCL): Forms waterproofing barrier layers in mining and construction sectors. Drilling: Ensures mud stability in oil and water well drilling. Foundry Industry: Used as a high-strength binder in casting molds. Cat Litter: Offers rapid liquid absorption and clumping properties. Agriculture: Enhances productivity as a soil conditioner and water retention agent. Cosmetics & Pharmaceuticals: Preferred as a toxin-binding and clarifying raw material. Advantages: Natural and Eco-Friendly: Does not harm the ecological balance. Self-Healing: Automatically seals micro-cracks through swelling. Cost-Effective: A long-lasting and economically efficient solution. Important Considerations: The chemical composition of the liquid (e.g., high salinity) and the compaction rate during application have a direct impact on performance.
