Ultrasonic vulcanization

摘要

Methods and apparatus for vulcanizing rubber and like material (10). Ultrasonic energy at about 10 to 100 kilohertz is applied to the material (10) at an energy intensity sufficient to generate heat to a temperature in the range of about 200 to 300 degrees Fahrenheit, while a static pressure is applied on the material (10) sufficient to prevent substantial cavitation and material degradation. The application of the ultrasonic energy and the pressure is maintained for at least about 10 minutes for each 1/8 inch in thickness of the material (10).
