Description
Descrizione dell’ invenzione industriale dal titolo: “Lastra isolante in DESCRIZIONE Description of the industrial invention entitled: "Insulating sheet in DESCRIPTION
Il polistirene espanso è uno dei materiali più utilizzati come isolante termico nelle costruzioni, viene solitamente usato nella colorazione bianca che lo protegge dalle radiazioni ultraviolette. La tecnica ha oggi messo a punto prodotti in polistirene espanso con un lambda migliorato grazie all’inserimento di particolare sostanze quali grafite o carbone amorfo, la migliorata resistenza termica comporta una colorazione grigia o nera che se il prodotto rimane esposta alla radiazione solare ne comporta un precoce invecchiamento con la perdita delle caratteristiche meccaniche. Expanded polystyrene is one of the most used materials as a thermal insulator in buildings, it is usually used in the white color that protects it from ultraviolet radiation. The technique has today developed products in expanded polystyrene with an improved lambda thanks to the inclusion of particular substances such as graphite or amorphous carbon, the improved thermal resistance results in a gray or black color that if the product remains exposed to solar radiation causes a premature aging with the loss of mechanical characteristics.
Per ovviare a tale inconveniente si è studiato un prodotto accoppiato in cui si inserisce una lastra con lambda migliorato all’ interno di una lastra di polistirene espanso tradizionale. L’applicazione avviene in macchina durante la realizzazione dell’involucro esterno, procedendo alla sinterizzazione e riuscendo ad ottenere una perfetta adesione fra i due prodotti. La protezione avviene sia sulla parte frontale, sia sulle parti laterali proteggendo il prodotto anche nelle fasi di trasporto e stoccaggio. Procedendo all’inserimento del prodotto a lambda migliorato in una fase successiva è possibile anche scegliere le caratteristiche meccaniche dei due prodotti in funzione delle esigenze tecniche, conducibilità termica o resistenza meccanica. To overcome this drawback, a coupled product has been studied in which a sheet with improved lambda is inserted inside a traditional expanded polystyrene sheet. The application takes place in the machine during the construction of the outer casing, proceeding with the sintering and managing to obtain a perfect adhesion between the two products. The protection takes place both on the front and on the sides, protecting the product even during the transport and storage phases. By inserting the improved lambda product at a later stage, it is also possible to choose the mechanical characteristics of the two products according to the technical requirements, thermal conductivity or mechanical resistance.
Le superfici sono poi trattate con una goffratura a rete idonea a migliorare le caratteristiche di aggrappaggio della finitura e sulla parte anteriore, quella esposta agli sbalzi termici, dei tagli trasversali che snervando il prodotto evitano possibili movimenti della superficie. The surfaces are then treated with a mesh embossing suitable to improve the adhesion characteristics of the finish and on the front part, the one exposed to thermal changes, of the transversal cuts which by yielding the product avoid possible movements of the surface.
Nella parte posteriore, qualora sia richiesta una riduzione delle caratteristiche di freno al vapore del materiale, si realizza una foratura non passante che crea delle camere d’aria in cui il vapore può passare riducendo quindi lo spessore di calcolo del fattore μ = fattore di resistenza alla diffusione del vapore. In the rear part, if a reduction in the vapor retention characteristics of the material is required, a non-through hole is made which creates air chambers in which the vapor can pass, thus reducing the calculation thickness by the factor μ = resistance factor to the diffusion of steam.
