Bentonite for Construction
1.Bentonite for Construction
2.Good Thixotropy,Suspension property ,etc.
3.Pass the ISO9001 and ISO14001 Certification.
Bentonite used for Construction and Civil Engineering
To be suitable for lower solid mud, has clear action on stop falling anything from caving and stop up leak.it has good close water base of interchangeability,thixotropy,lubrication,dilatancy,suspension property and similar to white powder, it is also or be used for oil and gas well drilling and civil-engineering include applied drilling fluid system, applied fluid solutions for diaphragm walls and piles, lubrication fluids for micro tunneling or pipe jacking,drilling fluids for water well, exploration and mining, fluids solution for shield tunneling.
