Introduction

Bentonite is an absorbent aluminium phyllosilicate, essentially impure clay consisting mostly of montmorillonite. There are different types of bentonite, each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Much of bentonite's usefulness in the drilling and geotechnical engineering industry comes from its unique rheological properties. Bentonite can be used in cement, adhesives, ceramic bodies, and cat litter. Bentonite is also used as a binding agent in the manufacture of taconite pellets as used in the steelmaking industry. Fuller's earth, an ancient dry-cleaning substance, is finely ground bentonite, typically used for purifying transformer oil.


Application

Drilling bentonite has the great expansibility under water, has the good colloid properties and can heighten the suspension of liquid viscosity.As a result,in drilling mud,bentonite can increase the drilling tools lubricity, Cleaning produces in the process of drilling cuttings, be widely used to complex geological structure formation drilling construction, to prevent hole accidents. The products are known for its good performance, strong water hydration expansion,big cation exchange capacity and high made pulp rate.
