Product Description

Bentonite for civil engineering Sodium Bentonite low price


why bentonite can be used for 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.

Bentonite is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite. 

The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al). Experts debate a number of nomenclatorial problems with the classification of bentonite clays.

Application

1.Used for foundry industry:

Bentonite can be used for bonding agent, absorbent, used in casting, ceramics, environmental management.

2.Bentonite used for drilling pulp:

pulp as binder, suspended with agent, SAP, applies to oil drilling,   basic engineering and construction cement.
3.Used for chemical industry:

Bentonite can be used for  bulking agent,thickener,suspension formulation,used to make paper, rubber, paint, ink, daily chemical, coating, textiles.
4. Bentonite can be used for Poultry feed additives :

used for chicken feed,  pig feed additive, plays the role of aid digestion.
