dielectric heating
- Definição1
- A process used to heat certain types of nonconductive plastic materials. The material to be heated forms the dielectric, or insulator, of a capacitor, and two metal electrodes act as the plates. Alternating current with a frequency of between 20 and 80 megahertz is placed acrosss the plates. The material between the plates is heated by the dielectric losses caused by the friction of the molecules moving under the influence of the rapidly changing electrostatic field. Dielectric heating is used to seal bags made of vinyl film and to cure certain types of plastic resins.
