  • Analysis of Chemically Bonded Sand Used for Molding in

    2018-5-15  The acid demand value (ADV) depends on the chemical composition of the sand. A catalyst requirement of cold-setting, acid catalyzed binders is selected as per ADV. If sands has ADV about 6-10 ml, it requires large quantity of acid catalyst and sand with ADV greater than10–15 ml are not acceptable for acid catalysed binder systems.

  • Acid Demand Value (ADV) Test Kit - Simpson

    The Acid Demand Value (ADV) Test measures the amount of basic material present in the sand that is soluble in a dilute acid solution. Since the reaction which cures the resin in many chemical binder systems is acid catalyzed, and since the acid is very mild, the presence of the basic material which can neutralize this weak acid will retard the curing reaction.
