Introduction Ashapura Sodium Bentonite
Ashapura Sodium Bentonite gives Bangladeshi industries a dependable swelling clay for demanding jobs. Ashapura Minechem in India mines and processes this premium powder to strict standards. The clay absorbs water quickly, expands many times its dry volume, and forms a smooth, thick gel. Therefore, drilling teams use it to stabilize boreholes and carry cuttings to the surface. Foundries rely on it to bind moulding sand, and civil contractors apply it to seal ponds, trenches and foundations. The fine 200 mesh powder mixes evenly and keeps its performance batch after batch. Moreover, each sealed bag protects the clay from moisture during storage and transport. In addition, buyers appreciate the steady quality, which reduces waste and saves time on site.

Frequently Asked Questions (FAQ)
Q1. What is Ashapura Sodium Bentonite?
Ashapura Sodium Bentonite is a high-swelling clay powder from India. It forms a thick gel in water and binds particles tightly.
Q2. How much water do I need to mix with it?
Most drilling jobs use 30 to 50 kg of powder per 1,000 litres of water. Add the powder slowly while you stir, then let the mix rest for a few hours.
Q3. Can I use it for pond sealing?
Yes. Spread the powder evenly over the pond bed, mix it into the top soil layer and compact it. The clay swells and seals the pores.
Q4. Does it work as a foundry sand binder?
Yes. Ashapura Sodium Bentonite gives green sand strong bonding and good mould strength. Foundries commonly add 4% to 8% by weight.
Q5. How should I store the bags?
Keep them in a cool, dry place off the floor. Close the bag tightly after use so moisture cannot reach the powder.
Q6. Does astzbd deliver across Bangladesh?
Yes. astzbd ships to all major districts and sends bulk orders by truck or courier.
