Epoxy resin sand consolidation rejuvenation
Patent
·
OSTI ID:6243517
A process is described for increasing the strength and stability of an epoxy resin-consolidated permeable mass of grains that has been weakened by a resin- degradative aqueous liquid. The mud acids, which comprise aqueous solutions of acidic materials that contain (or form) hydrofluoric acid, are particularly strong resin-degradative aqueous liquids. A consolidated permeable mass of grains that contains an epoxy resin grain-bonding material that has been weakened by exposure to a resin-degradative aqueous liquid is strengthened and stabilized by contacting the permeable mass with a polyfunctional organic silane capable of functioning as a resin-to-grain bonding agent.
