Understanding ADV and pH Testing for Mold, Core Sand

Understanding ADV and pH Testing for Mold, Core Sand

The ADV test for foundry sands uses 50.0 grams of sand mixed with 50 ml of distilled of deionized water adjusted to pH of 7, and 50 ml of dilute hydrochloric acid. The sand, water, and acid mixture is stirred for five minutes, then the mixture is analyzed to determine how much of the dilute acid has reacted with the impurities in the sand.

The Acid Demand Value is the amount of acid required to bring high pH and total alkalinity down to their proper levels. This gives insight to carbonates and salts in silica sand. A high acid demand value can lead to pinhole defects in castings due to the production of CO2 gas and lower the life of foundry sands in cold box systems.
