Product Description
manufacturer sodium bentonite professional manufacturer/7 years experience/strict quality control/timely shipment What's Bentonite? Bentonite is a clay minral predominantly consisting of mineral Montmorillonite mixed with some related minerals like Nontronite and Beidelite. 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. Generally speaking, the sodium variety has high swelling and gelling properities as well as good viscosity and liquid limit. So the properties of Sodium Bentonite is better than Calcium Bentonite. Sodium Bentonite is more popularly used in industries. Feature: good adhesion/good suspension/good lubricity/good thixotropy good plasticity/good catalytic/good exchangeability/good adsorbability API standard
OCMA standard
Advantage: Bentonite has the characteristic of high mud yield, high gel strength and low shear. It can improve the borehole stability especially in unconsolidated formation. The high performance and low concentration of bentonite can reduce the dosage, cost and intensity of labor. Application: Used for oil and gas well drilling and civil-engineering including drilling fluid system for horizontal directional drilling, fluid solution for diaphragm walls and piles, lubrication fluids for micro tunneling or pipe jacking, drilling fluids for water well, exploration and mining, fluid solution for shield tunneling. other type of bentonite: Bentonite for other applications available: Foundry/iron ore pelletising/construction and civil engineering/electrical earthing/ water proofing/agriculture/pesticides/animal feed/cat litter/pharmaceuticals, Cosmetics and medical applications/paper/ceramics
