Product Description

Bentonite   

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.

 usage  

Bentonite has special properties, such as swelling power, cohesiveness ,catalysis, thixotropy, suspension property and cation exchange property and so on, so it is widely used in various industrial fields. according to the uses, bentonite is divided into bentonite for mechanical casting use, bentonite for metallurgy pellet, bentonite for drilling mud, bentonite for agricultural building materials, bentonite for civil engineering.
