Product Description
Sodium bentonite expands when wet,
absorbing as much as several times its dry mass in water.
Because of its excellent colloidal properties, it is often used in
drilling mud for oil and gas wells and boreholes for geotechnical
and environmental investigations.
The property of swelling also makes sodium bentonite useful as a
sealant, since it provides a self-sealing, low permeability
barrier. It is used to line the base of landfills for example.
Various surface modifications to sodium bentonite improve some
rheological or sealing performance in geoenviromental applications,
for example, the addition of polymers.
Calcium bentonite is a useful adsorbent of ions in
solution, as well as fats and oils. It is the main active
ingredient of fuller's earth, probably one of the earliest
industrial cleaning agents.
Calcium bentonite may be converted to sodium bentonite to exhibit
many of sodium bentonite's properties. In common usage, this means
adding 5–*0% of a soluble sodium salt such as sodium carbonate to
wet bentonite, mixing well, and allowing time for the ion exchange
to take place and water to remove the exchanged calcium. Some
properties, such as viscosity and fluid loss of suspensions, of
sodium-beneficiated calcium bentonite may not be fully equivalent
to those of natural sodium bentonite.
