Bentonite has a big expansion after meets water, has a good colloidal nature, can increase the viscosity of suspension in the drilling mud when used, can increase the lubrication of drilling,cleaning the debris during drilling, as well as for the rig-freeing agent. So which is widely used in complex geological formation drilling
This product has a property of swelling in water and the swelling index can reach from 15 to 20. What's more, the high-density colloids formed after expanding. have exclusive performance of water. Due to this property , natural sodium bentonite can be used as water-proof material in many fields.

Application / Models
The water-proof property of natural sodium bentonite is mainly embodied in three fields. To be more specific, it has an anti-seepage effect in the field of construction engineering municipal engineering, subway, garden, artificial lake) and has anti-seepage effect as well as corrosion resistant effect in the field of environmental sanitation. Besides, it also has an anti-seepage effect in the field of hydraulic engineering( reservoirs and dams of rivers or lakes).
Our company is mainly engaged in non-metallic mineral products manufacturing and processing, especially experienced in bentonite and proppant. Our bentonite products are chosen from high quality bentonite mine, through careful processing, made into different usages bentonite products, including waterproofing, drilling fluids, plant oil fading, waste oil recovery, cat litter, paint and so on.
