The product is well-known for the good performance of good hydration, strong expansion with water, large exchange amount of positive ion and high mud production rate,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 projects.
