High-Quality Sodium Bentonite
Catalog NO.: AIMRSE-CHM-ADD-144 Manufacturer PN: CHM-BEN-HIQ
• High yield value; good wellbore protection effect; selective flocculation characteristics; improves the lubricity of the mud cake.
Increases viscosity and shear strength to enhance wellbore cleaning capacity. Reduces fluid loss while forming a thin, tough mud cake. Improves wellbore stability in poorly cemented formations. Specifically designed for tunnel boring, pipe jacking, pile driving, and drilling operations.
This product is a high-quality sodium-based bentonite treated with a special process and enhanced with polymer components, achieving a higher dynamic plasticity ratio after hydration. It simultaneously meets the technical requirements for OCMA-grade bentonite under both GB national standards and API specifications. One ton of this product can formulate 25m³ of drilling fluid with a viscosity of 15mPa·s. It is primarily used in water-based drilling fluids to form mud cakes, reduce fluid loss, and suspend cuttings and barite.
