Benefits of Using Foundry Grade Bentonite
- Enhanced Mold Strength: Our bentonite provides superior green compressive strength (GCS), reaching up to 800, which ensures robust and durable molds capable of withstanding the stresses of metal casting.
- Optimal Swelling Properties: With a free swelling value of 32, our bentonite meets the ideal range, ensuring excellent bonding strength and sand mix permeability.
- Controlled pH Levels: Maintaining a pH level of 10, our bentonite is well within the standard range of 9-11, ensuring compatibility with other additives and preventing adverse chemical reactions.
- High Purity: The methylene blue (MB) value of 420 mg/gm of clay indicates high purity and exceptional ability to enhance the plasticity and strength of the sand mixture.
- Efficient Grain Distribution: With 90% of particles passing through a 200 mesh, our bentonite ensures a fine, even distribution, critical for smooth mold surfaces and accurate castings.
- Moisture Control: Our product maintains an optimal moisture level of 12%, balancing plasticity and dryness for easy handling and efficient molding processes.
- Immediate Gelling Time: The instant gelling time of our bentonite facilitates quick preparation and application, enhancing operational efficiency.
- Reliable Wet Tensile Strength: Achieving a wet tensile strength (WTS) thermal value of 0.20, our bentonite ensures the molds maintain their integrity during the casting process.
