The bentonite products available on the market can be divided into three basic types: natural calcium or sodium activated sodium polymer-modified

Application of Bentonite

The most common use of bentonite is in drilling fluids. The material  in the flush fluid lubricates and cools the cutting tools while protecting against corrosion. As the drilling fluid generates hydrostatic pressure in the borehole, it hinders fluid and gas penetration. Sodium is a natural sealant and is used for sealing stock and recreational ponds, dairy and sewage lagoons, and city landfills. It is also effective as a hole plug as well as for controlling dust on highways. It is one of the “most effective low cost methods” of treating porous soils Material slurries are known to perform the following pivotal functions: a) Support the excavation by exerting hydrostatic pressure on its walls ie to prevent the collapse or retain an area. b) Remain in the excavation, and not flow to any great extent into the soil thereby acting as a sealant.

Properties of Bentonite

The special properties of the product (hydration, swelling, water absorption, viscosity, thixotropy) make it a valuable material for a wide range of uses and applications. It is deposits are normally exploited by quarrying. Extracted is distinctly solid, even with a moisture content of approximately 30%

Density

Bentonite apparent density , when quarried and piled under natural moisture conditions, ranges from 1.5 to 1.8 g / cm3. Its density when dry varies depending on the quality, and may range from 2.2 to 2.8 g / cm3

How to use?

Very slowly add a half sack of Bentonite to the water and circulate it with the mud pump. This results in very thorough mixing with no lumps. When mixed in a vessel this size, use a full sack of the product to get a very thick mud. This mud will then be diluted when it is added to the mud pits.

PH of Bentonite

As described on a previous page, the pH of the water used when mixing it has a significant effect on whether it  can be fully hydrated. The pH of the water, before adding it , should be in the range of 8.5-9.5; this is slightly alkaline.

Packing

It can pack in 50Kg bag /500Kg jumbo bag/1000Kg jumbo bag/1500Kg jumbo bag

Safety of usage

It  is ground naturally occurring clay. It is inorganic, non- toxic , non-irritating. It is not considered hazardous on skin contact (it is employed in cosmetics and skin products as a suspender). Eye contact hazards are similar to those of any other clay, flush to remove the particles.

Descriptions

Natural (Calcium or Sodium)? The water absorption and hydration capacity of it differ greatly and depend on which cations are attached between the elementary layers .Calcium with bivalent Ca2+ and/or Mg2+ ions has a water absorption capacity of one and a half to two times its own weight; for sodium with univalent Na+ ions between the layers, this is five to ten times. The exact values depend on the deposit genesis of the product, its montmorillonite content, the sodium content and the type of ion exchange. Activated or active Since natural sodium is less common than calcium , it is considerably more expensive. Calcium can however be converted into sodium by exchanging the ions. This can be undertaken naturally by adding sodium carbonate (Na2CO3) or through a technical process.
