1. Industrial Applications
Sodium bentonite is a versatile industrial material with strong swelling, adsorption, binding, and rheological properties. It is widely used in soil stabilization, waterproofing, drilling fluids, pelletizing, foundry sand, coatings, paints, and greases. Its chemical stability, additive compatibility, eco-friendly nature, and cost-effectiveness make it suitable for improving efficiency, durability, and safety in many industries.

2. Iron Ore Pelletization
In iron ore pelletization, sodium bentonite works as an effective binder for fine iron ore particles. It improves pellet plasticity, water retention, and shaping performance, helping reduce cracking during rolling and drying. After firing, it supports pellet strength for handling, transportation, and smelting, while offering reliable performance and good cost efficiency.

3. Foundry Molding Sand
For foundry molding sand, sodium bentonite binds sand particles into stable molds and cores for steel, iron, and aluminum alloy casting. It improves green strength, dry strength, and thermal stability, helping molds resist deformation during pouring. Its water retention and permeability balance also help reduce casting defects and support sand reuse.

4. Coatings, Paints & Greases
In coatings, paints, and greases, sodium bentonite acts as a thickener, suspending agent, and stabilizer. It helps prevent pigment settling, improve viscosity, reduce sagging, and enhance application stability. In greases, it supports shear stability, anti-settling performance, and wear protection, making formulations more durable and easier to store.

Multifunctional Physicochemical Performance: Delivers exceptional swelling capacity (10–20x dry volume), high cation exchange capacity (≥80 meq/100g), and thixotropic/rheological adjustability; enables adsorption, binding, thickening, and impermeability, adapting to diverse industrial scenarios (drilling, casting, waterproofing, coatings).

Cost-Efficient & Process-Optimized: Low addition rates (0.5–8% depending on use case) reduce material costs; easy to disperse, hydrate, or mix with substrates (soils, ores, sands, formulations); enhances product durability (e.g., pellet strength, coating adhesion) and process efficiency (e.g., drilling fluid circulation, mold reclamation), minimizing waste and operational risks.

Environmental & Operational Compatibility: Chemically inert, non-toxic, and eco-friendly, with low impurity content (SiO₂/Al₂O₃ controlled per application); stable across temperature (-20–1200℃) and pH (3–11) ranges, compatible with polymers, solvents, and industrial additives, ensuring consistent performance in harsh conditions.

Sodium bentonite stands out as a versatile industrial material with core advantages driving widespread adoption. Its exceptional swelling, adsorption, and rheological properties enable multifunctional performance—from stabilizing soils, sealing waterproofing, and enhancing drilling fluids to binding pellets and thickening coatings. Chemically stable across harsh conditions (temperature, pH variations) and compatible with diverse additives, it ensures reliable operation in civil engineering, metallurgy, drilling, and manufacturing. Cost-effective, abundant, and eco-friendly, it offers low addition rates, reduces waste, and replaces synthetic alternatives. Its inert, non-toxic nature complies with industrial standards, making it indispensable for improving efficiency, durability, and safety across industrial applications.
