Abstract The characteristics of pressure-assisted
microwave vulcanization of rubber were studied in a monomode
cavity. For this purpose a modified cylindrical cavity was designed taking
into account the external pressure of dielectric molds
at the same time that heating was taking place. The monitoring of dielectric properties of
rubber sample during the vulcanization process was demonstrated to be of the
utmost importance to correlate the evolution of the rubber when is heated
with microwaves with the main processing parameters (viscosity and degree of
cure). The results obtained looked promising as the vulcanization rates were
accelerated giving vulcanized samples comparable in quality to conventional
treatment methods. Key Words: Rubber vulcanization, Resonant
cavity, Pressure, El;ect4romagnetic simulation, Dielectric properties |
