BENTONITE

 

Bentonite is the main and gel-forming component of water-based drilling muds and is used for preparation of the fresh and salt drilling muds. Bentonite-based clay suspension is the simplest type of water-based drilling mud having set of technical characteristics. It is firmer as against calcium gel powder-based drilling muds.

Critical index of bentonite quality is the mud yield, number of cubical meters of clay suspension, specified density and funnel viscosity obtained from one tone of products.

Powder has deep-beige color (cervine).

SAND BLEND BENTONITE

 

Activated powdered bentonite is used as binding agent of sand blends in the manufacture of casting molds on the mechanized and automatic lines for high-duty castings of ferrous and nonferrous alloys. It is environmentally friendly.

Activated powdered bentonite provides:

  • Stabilization of physical and mechanical properties and handling ability of sand blends at the target level;
  • Reduction of bentonitic binding agent consumption;
  • Increase in dimensional and weighting accuracy of castings;
  • Reduction of defective castings;
  • Improvement of technical and economic performance of casting shops.
