Bentonite Clay's Role in Green Sand Metalcasting Foundry

In a green sand system, the clay and water combine to form a clay bridge that binds sand grains to one another. This bond­ing mechanism is a hydrated system that requires water, energy, time and technical expertise. Two types of bentonite clay are typically used: calcium bentonite and sodium bentonite.

What is Bentonite? Industrial Minerals Association

Foundry: Bentonite is used as a bonding material in the preparation of molding sand for the production of iron, steel and non-ferrous casting. The unique properties of bentonite yield green sand moulds with good flowability, compactability and thermal stability for the production of high quality castings.

Chapter 7 Monitoring Well Design and Installation

The intake consists of a filter pack and screen. The screen allows water to enter the well and, at the same time, minimizes the entrance of filter pack materials. The filter pack is an envelope of uniform, clean, well-rounded sand or gravel that is placed between the formation and the screen. It helps to prevent sediment from entering the well.

Bentonite-Based Drilling Mud: The Facts

Nov 09, 2011· After advancing the boring, setting the screen/riser and sand pack, the vertical driller usually pours dry bentonite chips or pellets into the annular space between the vertical well and formation. The vertical driller then adds water to hydrate the bentonite, creating a very effective seal as the bentonite swells (or “yields”).

THE USE OF CLAY AS AN ENGINEERED BARRIER IN RADIOACTIVE

This may also be the case for saturated sand-bentonite mixtures if the sand content is sufficiently high. At a degree of saturation of ~80–90% or higher, the behavior changes entirely (Villar et al., 2012). No flow of gas will take place in the bentonite unless the applied pressure is equal to or greater than the total stress (swelling
