SHIELDING DEVICES FOR THE ELECTROMAGNETIC WAVES, WHICH ARE UTILIZED FOR INDUSTRIAL APPLICATIONS OF VARIOUS KIND, AND IN PARTICULAR ELECTROMAGNETIC WAVES ABSORBING TILES

摘要

Shielding devices for the electromagnetic waves, which are utilized for industrial applications of various kind, between which also in industrial microwave oven (15). Devices comprising a plurality of absorbing tiles (5) for electromagnetic radiations, adapted to absorb the energy of the electromagnetic waves having different wavelength. The absorbing tile (5) are obtained by means of a mixture of materials for shielding radiations with frequencies variables between 2 and 3 GHz, comprising for example, graphite, carbon black, iron powder, silicon carbide, cement and water, which mixture is poured at environmental temperature into dies specifically shaped. There are described different manufacturing shapes of tiles (5) and the positions in which the same are applied on industrial microwave ovens (15).
