Product Introduction
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.
Product Use
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).
