Foundry Grade Sodium Bentonite

Foundry Sodium Bentonite is an indispensable core binder in the clay sand casting material system, as well as a key cast iron auxiliary material to ensure stable operation of cast iron production. It undertakes important functions of improving sand mold strength, fluidity and reusability in green sand and clay sand processes. Selected from high-grade montmorillonite ore, this product is made through deep sodium modification, grinding classification, purity optimization and other processes, with high expansion ratio, high wet compressive strength, high hot wet tensile strength and excellent suspension stability. It can work synergistically with foundry coal powder, foundry compound sand and foundry starch to build a high-performance clay sand material system. As a professional clay sand casting material, this product can significantly improve sand mold wet strength, thermal stability and collapsibility, keeping sand molds structurally intact under high-pressure molding, high-speed pouri…
