The invention relates to screening systems which comprise semi-conductive panels made of thermoplastic polymeric materials recycled from electric and electronic equipment waste such as: server rooms, EMC test cells, computer cases and the like, thermally insulating elements such as polystyrene and mineral wool, and gluing materials such as polyurethane adhesive and adhesive mortar, the screening systems also having, besides the screening properties, good sound- and heat-insulating properties, and low production costs, they being meant for constructions industry. According to the invention, the screening systems consist of a semi-conductive panel made of recycled thermoplastic polymeric materials which have, in their matrix, nano-conductive powders, of electric and electronic equipment waste, having applied thereon, in a first embodiment: a. a polystyrene plate with a thickness of 50 mm, glued with polyurethane adhesive applied as lines and points, on the upper surface of the polystyrene there being applied, by grouter, a layer of adhesive mortar sealant wherein a wire mesh is embedded, over which another adhesive mortar coat is applied, to integrally embed the wire mesh, while in the second embodiment: b. a layer of mineral wool with the thickness of 100 mm is glued with polyurethane adhesive, applied as lines, over which an aluminum foil is placed. |
