Product Description
BentoniteWith good capacity of suspension and thixotropy, bentonite fordirectional 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 ofmud-made, easydispose and etc. At the moment, many Non-dig companies haveapplied this kind of bentonite in many directional through-passing constructionsuch as West-East natural gas transmission project, which has approved thebentonite for directional through-passing is the basic ideal material for allkinds of projects.

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