BENTONIT D 140 is manufactured from activated, selectively extracted and processed bentonites.
Selection of raw materials and way of their processing are focused on utilization of rheological properties of bentonite.
It is characterized by following values:
| Name of the product | BENTONIT D 140 | |
|---|---|---|
| Declared properties | fineness of grinding | min. 95 % under 0,015 mm |
| bulk density | approx. 450 kg/m3 | |
| moisture | max. 12 % | |
| pH | 9 - 11 | |
| montmorillonite content | min. 75 % | |
| Packing | paper sacks | 15 kg |
| big-bag | 600 kg | |
| bulk bentonite | 16 000 kg |
BENTONIT D 140 is manufactured from natural raw material; reasonable differences from declared properties may occur.
USE: Component of drilling mud for vertical drilling.
