Low Viscosity Sodium Carboxymethyl Cellulose for Drilling Fluid (LV-CMC)
1.Features
white or yellowish fibrous powder. Moisture-absorbed, smell-less, odorless, non-toxic, not easy to ferment, insoluble in acid and ethanol organic solvent, easy soluble in water to form a colloidal solution, good tolerance with salt and good thermal stability.
The quality index includes the quality index and technical index of drilling fluid.( see table1 and table2)
2. Application
Mainly used in water-based drilling fluids to reduce filtration loss.
