Sep 04, 2019· There are two types of bentonite clays. While calcium bentonite is used on the body, both internally and topically, sodium bentonite has more industrial uses. Sodium bentonite clay is used as a natural sealant, such as to seal roads, lagoons, landfills and ponds. It has natural swelling abilities, swelling 15–18 times its dry size when ...
The HY series bentonite (inorganic gel) rheological additives could be used as pre-gel:The preparation of a pre-gel concentration should be decided according to the desired viscosity level of the stirring speed and the product of the dispersing device in order to obtain the best results.Generally
Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets, and in foundry and oil - well drilling mud. Bentonite also acts as a suspending agent in oil - well drilling fluids.

Uses of Bentonite in Construction. The recognition of bentonite as a vital construction element is still in its latent stage, since a hefty percentage of foundations and other civil engineering activities are still carried out without using bentonite and are incurring much higher expenditure through use of .
Bentonite possesses thixotropic properties and deposits a thin water proofing film on the walls of the bore holes & thus renders permeable formations impermeable. Both natural & synthetic Bentonite are used in preparation of drilling muds. It is mainly used as circulation mud in rotary system of drilling for oil.
Bentonite–water systems are of great importance for agricultural, industrial, environmental and civil engineering activities such as desiccant preparation, sealant, ceramic, box adsorbent, iron ore pellet, molding sand for foundry, drilling mud and arrieres for water and protection from nuclear waste,, .
Bentonite is valued in foundry sand binding, drilling ... industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets and in foundry and as oil-well drilling mud. Bentonite also acts as a suspending agent in oil-well drilling fluids. Bentonite exhibits good green strength
Bentonite clay is a clay which is an absorbent aluminum phyllosilicate consisting mostly of montmorillonite. The main uses of bentonite clays are for drilling mud, and as a binder, purifier, absorbent and groundwater barrier. Bentonite clay is a chemically inert, non-corrosive, natural clay.
Finely comminuted, crude bentonite may be purified of accompanying quartz, muscovite, illite, feldspar, iron oxide and like impurities by pouring an aqueous slurry of the clay into a very dilute aqueous solution of a technical grade of sodium hexametaphosphate, and letting the mixture stand a few minutes, whereby almost the entire mineral impurities present are precipitated.
Bentonite is valued in foundry sand binding, drilling industrial appliions. Sodium bentonite is well suited as a binder in the preparation of pellets and in foundry and as oilwell drilling mud. Bentonite also acts as a suspending agent in oilwell drilling fluids. Bentonite exhibits good green strength. Read more
When using bentonite as a binder, the technical catalyst showed a decreased bio-oil deoxygenation activity, which was assigned to the loss of most of ZSM-5 acidity by ion-exchange with Na + cations from the clay. In bentonite besides Na, there are other cations such as Fe, Mg, K, and Ca, the presence of which can inhibit catalytic activity.
The comparative study on preparation and characterization of modified bentonite and kaolin clay types is aimed at establishment of the ability of these clay types to adsorb pollutants. Its low cost, availability and recovery of clay give it added advantage of an effective adsorbent.
