  • System and method for altering the tack of materials using an electrohydraulic discharge
    Patent number: 7294233
    Abstract: A system and method for altering the tack of a material, namely a polymer used as an adhesive, also known as stickies, or pitch. The present invention reduces the tack of the stickies and pitch by exposing the materials for a short duration to low-energy pulsed electrical discharges between a pair of electrodes that are submerged in a liquid medium, such as a fiber stream, water, a pulp slurry, or whitewater.
    Type: Grant
    Filed: December 18, 2002
    Date of Patent: November 13, 2007
    Assignee: Georgia Tech Research Corporation
    Inventors: Sujit Banerjee, Howard Corcoran
