Bentonite is characterized by the large specific surface good adsorption ion exchange ability and nontoxicity An enhanced bentonite base composite flocculant (BTA) can be prepared from treating the calcium base bentonite and compositing various functional additives Bentonite was firstly treated by citric acid then the talc and activated carbon turned to be acid part and simultaneously

Properties of Bentonite Magmas

Bentonite magma is used as a thickening agent in paints dyes and polishes Bentonite when exposed to liquid thickens and forms a gel or paste according to the Industrial Minerals Association of North America This same thickening ability makes it an effective lubricant in diaphragm walls foundations and in tunneling and drilling operations

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

Montmorillonite is a multifunctional clay mineral and a major component of bentonite Montmorillonite has been used in various industrial and pharmaceutical fields due to its unique characteristics which include swelling and adsorption The high adsorption capacity of montmorillonite contributes to increase drug entrapment and sustained-release of drugs

The results showed that the sodium bentonite had the best adsorption effect on Cu2+ and the organic bentonite (1831-bentonite) had the best adsorption effect on the oil In this thesis a modification model of bentonite was established to explain the modification mechanism more clearly and clearly show the internal change process

The present investigation studies the regeneration of waste engine oil by active Ca-bentonite powder Preparation and characterization of nano process Bentonite Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite bentonite is uniquely useful in the process of winemaking

ABSTRACT —Preparation of a ceramic floor tile body containing pure bentonite as strengthening agent This paper demonstrates that the use of a low amount (2 wt%) of alkali activated bentonite as strengthening agent of low plastic ceramic body is greatly recommend ed since it appreciably reduceunfres ruptured s of ceramic tiles in their

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

We selecte two bentonite products: activated clay and organo-bentonite and introduce the related content of them like industrial applications technology and raw materials of producting at the same time After that we choose the preparation processes of activated clay and organo-bentonite Choose conditions of the prepared samples arranging test methods by orthogonal test program and
