Product name: Bentonite (industrial grade)

Introduction: Bentonite is an important inorganic mineral in the earth.The main component of bentonite is montmorillonite.It is widely used in industrial fields,e.g. for oil drilling fluids,construction,coating,agriculture&fertilizer,metallurgy,waterproofing.

1.       Bentonite for drilling fluids

Our sodium/calcium bentonite for drilling conforms to national standards People's Republic of China: GB / T5005-2010.It has a good suspension, thixotropic, low fluid loss and good mud performance.The preparation is convenient and it is easy to adjust the proportion of drilling fluid. It is the essential ideal base material of deep drilling and ocean drilling.

2.Salt resistance bentonite  

Salt resistance bentonite is free from environmental and geographical restrictions, you can place water, are not subject to the constraints of weather conditions, you can always use it. It has a quick dissolution speed, high hydration capacity and mud rate, good stability, high capacity of solid wall, low drill swing resistance, high drilling rate, low amount of fluid loss. Especially when encountered in the sediment layer and the salt layer in the construction ,its strong inhibition can prevent collapse with strong inhibition and also prevent to expand of the holes, reduce to meet resistance in the drilling process, be not to the end or sticking, etc.

3. Bentonite for foundry

It is suitable for casting the wet type, dry type, table dry, high-pressure type, such as different processes steel, cast iron production.

The main features are:

(1)by adding less, high strength;

(2)good air permeability;

(3)heat and moisture high tensile strength, high resisting sand inclusion ability.

(4)temperature resistance;

(5)good reusability. Used as a core sand binder can make sand has good process performance, improve casting surface finish, ensure casting quality, and increase yield.

4. Bentonite for metallurgy

Sodium Bentonite for metallurgy is as special metallurgical pellet binder for iron ore pellet, in a variety of fine iron ore sand bond pellets, can significantly increase raw pellet strength and ruptures temperature to expand roasting area, the permeability of raw material layer is good, and improved pellet quality, reduce costings. It can improve pellet quality, reduce costs and significantly improve the economic efficiency of iron and steel enterprises.

5.Bentonite for Construction and Civil Engineering

It has large expansion speed, anti-aging, anti-corrosion and other advantages. For impermeable material and make an ideal base seal, waterproof blanket, waterproof board and waterproof material.
