Bentonite for drilling

        With the  good capacity of colloid,this product can highten viscosity,with good capacity of hydrophily,lubricationg and suspension. It is widely applied in drilling construyction of complicated underground structure,and can take the rock fragments,avoid of broken bits from the well ,sloughing and leaking stoppage.
