Reliable Sodium Bentonite for Casting Applications

Aiming at the high-temperature, high-pressure and high-speed production trend of clay sand casting, Foundry Sodium Bentonite has become a high-performance special clay sand casting material through technological upgrading and process optimization, and is also a high-quality cast iron auxiliary material to meet the needs of modern cast iron production. Selected from high-purity sodium bentonite ore, this product removes inert impurities such as quartz and feldspar, retains high-activity montmorillonite components, and undergoes ultra-fine grinding and precise classification, ensuring rapid dispersion and uniform film formation in sand molds, greatly improving bonding efficiency and molding sand stability. As a professional clay sand casting material, this product has ultra-high wet compressive strength, excellent thermal stability, good fluidity and collapsibility, which can effectively resist high-temperature iron liquid scouring and thermal expansion stress, reduce defects such as san…
