Does Water Quality Affect Green Sand Properties?

摘要

Water-soluble salts or electrolytes are just some of the mineral contaminants found in everyday tap water used by foundries across the U.S for their green sand systems. Bentonite is the main bonding compound of green sand systems, and for it to have quality bonding, it first must be activated with the use of an agent. A good activating agent must fulfill three requirements: ? Be distinctly soluble in water, having a solubility of at least 1 g/100 g of water.
