Bentonite for casting mainly includes sodium bentonite and calcium bentonite. Sodium bentonite is processed from natural sodium bentonite or artificial sodium bentonite. It is popular in the foundry industry for its good reusability and high wet compressive strength. . Due to its good plasticity, it can prevent sand inclusion, scarring, falling blocks, sand mold collapse and other phenomena in castings. In addition, it has strong formability and high cavity strength, which is convenient for casting wet or dry molds in the metal industry. It is the key to sand adhesion of castings.
