Bentonite
Bentonite is a clay mineral predominantly consisting of mineral Montmorillonite mixed with some related minerals like Nontronite and Beidellite. These are three layered Aluminosilicate with molecules of water between layers. For natural Sodium Bentonite, exchangeable sodium cations are predominant, rather than other cations like calcium, magnesium etc. Similarly in Calcium Bentonite, calcium cations are predominant. In fact in all Bentonite available in the world, the sodium variety has high swelling and gelling properties along with good viscosity and liquid limit.
The Bentonite found in the Kutch region of India is of igneous origin. It was formed millions of years ago, possibly from the volcanic ash falling in stagnant saline water in semi-arid conditions. Due to the natural characteristics of these particular volcanic ashes, the chemical composition of this Bentonite is somewhat different from the Bentonite available in the rest of the world. Most of these deposits are of natural sodium Bentonite with higher iron content which gives them their darker colour. Due to very fine particle size, this Bentonite shows extra-ordinary swelling capacity and bonding powers. These differences mean that the Bentonite finds the most number of uses in various industries throughout the world.
SUPERBOND is unique blending of Sodium and Calcium based Bentonite. SUPERBONDTM is extraordinary solution for foundry sand binding and it can also withstand higher temperature since it contain more percentages of metallic i.e.: Alumina and Ferrous contain. The foundry is able to maintain active clay levels with reduced additions of bentonite since SUPERBOND is having high Mont values. It also offers more superior thermal durability. This feature makes SUPERBONDTM ideal for applications that require high heat loads or high melt temperatures. Besides cost savings from lower bentonite adding one additional benefit is that there will be less waste fines to discard so disposal costs will be reduced.
SUPERBOND-IOP is unique Sodium based Bentonite. SUPERBONDTM-IOP is extraordinary solution for Iron Ore Pellet binding and it can also withstand higher temperature since it contains more percentages of metal. The grade is also having higher natural percentage of Iron which is ideal in isolating ore pellets with the maximum percentages of Iron. The Iron Ore Pelletization plant can able to maintain active clay levels with reduced additions of Bentonite since SUPERBONDTM-IOP is having high Mont values. It also offers more superior thermal durability. This features makes SUPERBONDTM-IOP ideal for applications that require high heat loads or high melt temperatures.
Well Drilling remains one of the largest volume market for Bentonite. The important characteristics of this type of Bentonite are Mud yield, Gel Strength and wall building properties. The specification of drilling mud is given as per American Petroleum Institute ( API ) and as per Oil Companies Materials Association (OCMA). Manek Group offers well knows brand as “NATURAL PLUS-XL” and “NATURAL PLUS-30”. Tailor made products can be offered upon request.
