RAPID DRYING OF POLYAMIDE RESINS USING HIGH FREQUENCY ELECTRIC FIELDS

摘要

A process for quickly drying thermoplastic polyamide resin by the use of a high frequency electric field. The process comprises placing the polyamide between at least two electrodes, applying a high frequency voltage to the electrodes to produce a heating rate of the polyamide between 0.5 DEG C. and 50 DEG C./min, and then removing the water evolved from the polyamide.
