Fumigant Dealers in Manachanallur, Tiruchirappalli

We are among the leading Exporters & Suppliers of Bentonite Powder. Bentonite is one of the two naturally occurring minerals of montmorillonite group with decolorizing and absorbing properties, the other minerals of this group being Fuller̢۪s Earth. On exposure, almost all Bentonite assume a slightly darker shade due to absorption of moisture. We offer Bentonite Powder of primarily two types, Calcium Based Bentonite and Sodium Based Bentonite. In reality, two types of Bentonite viz., swelling and non-swelling types are commonly known in trade. Sodium Bentonite is of swelling type while Calcium Bentonite is non-swelling. Bentonite is believed to have been formed by the alteration of volcanic ash deposits, mostly of Upper Cretaceous Age. The commercial importance of Bentonite Powder depends more on its physico-chemical properties such as base-exchange capacity, thixotropy, settling time, swelling power, pH value, etc. then on chemical composition. We supply Bentonite Powder with all these properties. Treated Bentonite Powder has been used in palletizing of iron ore fines, in ceramic nuclear fuels and ceramic moderators. Sodium Bentonite and Calcium Bentonite Sodium Bentonite and Calcium Bentonite are distinctly characterized by high ration of their dominant exchangeable base. Intermediate type Bentonite may have either sodium or calcium base dominant but in low or nearly equal ratios-mixed Bentonite may exhibit low, high or equal ration of sodium and calcium iron but contain a higher percentage of non-clay material and/or other clay minerals. Plasticity and bonding strength of all Bentonite and dilatency (swelling capacity) viscosity (resistance to flow), thixotropy (getting strength) of sodium Bentonite are all due to colloidal nature of Bentonite. Sodium Bentonite (high swelling-high gel) are strongly hydroscopic exhibiting a great affinity for water. Non-swelling Bentonite (sub-Bentonite meta-Bentonite) are calcium Bentonite. Calcium Bentonite is more common than sodium Bentonite because calcium is higher in the replacement series.
