Bentonite

Bentonite can be used in Drilling Mud, r Directional Through-passing, Cat Litter, Casting Soil

Bentonite for Drilling Mud

With the good capacity of colloid, bentonite for drilling mud can heighten viscosity, with good capacity of hydrophily, lubricating and suspension. It is widely applied in drilling construction of complicated underground structure, and can take the rock fragments, avoid of broken bits from the well, sloughing and leaking stoppage.

3	Filtrate volume cm3≤	15
4	75μm residue on sieve%≤	4

Bentonite for Directional Through-passing

With good capacity of suspension and thixotropy, bentonite for directional through-passing is the same nature with Bentonite for Drilling Mud. It also has a lots of advantages, such as low filtrate volume, good capacity of mud-made, easydispose and etc. At the moment, many Non-dig companies have applied this kind of bentonite in many directional through-passing construction such as West-East natural gas transmission project, which has approved the bentonite for directional through-passing is the basic ideal material for all kinds of nondig projects.
