Product Name:Bentonite
English Name:Bentonite
CAS No.:1340-69-8
Aliases:Bentonite powder, White clay, Montmorillonite clay
Molecular Formula:Al2H2O6Si
Physical Properties:This product is a gray-white to light yellow powder with no odor. It is insoluble in water and organic solvents, but can absorb water and swell to form a gel-like dispersion. Its main component is montmorillonite, which exhibits excellent adsorption, suspension, binding properties, and cation exchange capacity. The relative density is approximately 2.4-2.8, melting point is about 1330°C, with a large specific surface area and stable chemical resistance to acids and alkalis.
Uses:Bentonite is widely used as a thickening and suspension stabilizing agent in drilling mud, and as a sand binder in the foundry industry to improve casting quality. In construction, it is applied in waterproofing materials and concrete modification. Additionally, it serves as an environmentally friendly adsorbent for removing heavy metals and organic pollutants from wastewater.
Technical Specifications:
Blue absorption value: ≥30 g/100g, reflecting montmorillonite content
Swelling index: ≥15 mL/g, indicating hydration and swelling performance
Montmorillonite content: ≥60%, ensuring product purity
pH value (5% aqueous dispersion): 8-10, weakly alkaline
Moisture content: ≤12%, ensuring storage stability
