Low Viscosity Sodium Carboxymethyl Cellulose for Drilling Fluid (LV-CMC)
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.
3. Package:25Kg /bag, sealed in 3-in-1 compound paper bag with plastic lining.
4. Note: During storage and transportation, the bag should be protected from moisture and rain. Keep the products in dry and ventilated place.
