Bentonite for drilling
Bentonite undergoes great expansion when it is caught in water, so it possesses good characteristics of colloids, and it can add viscosity of suspension. When used for drilling mud, it can add lubrification of drilling too can clean rock cuttings produced in the course of drilling well. It can be extensively used for drilling construction of complex tectonic layer to avoid the hole trouble.
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.

Directional crossing bentonite
HUAWEI Directional Crossing Bentonite has good Thixotropy andSuspension property ,dissolving speed, strong rheological properties, high mud-making rate, good lubricating performance, low friction coefficient, etc, which made mud soil has stronger ability of carrying drilling cuttings and protect the hole wall and the hole in the wall formed certain mud skin, maintain the stability of hole wall, prevent infiltration of advantages, is the ideal geological exploration drilling and trenchless through engineering materials .According to the requirements of the engineering geological conditions.

Salt resistance bentonite
Application of Manufacturing Techniques of Slurry by Seawater ,anti- salt bentonite from environmental geographical restrictions to get water,unaffected by severe weather, can be used at any time. It has a fast speed of dissolving, good hydration , high mud-making rate, very thin, strong stability, high abaility of solid wall, low drill swing resistance, high drilling rate etc. Especially encountered sediment layers and salt in the construction, can prevent to collapse with strong inhibition ,also prevent to expand of the holes, reduce to meet resistance in the drilling process, be not to the end or sticking, etc.
