DESCRIZIONE DESCRIPTION
La presente invenzione riguarda un metodo e relativo impianto per la creazione di pigmenti conduttivi a partire da scarti di produzione di tagli laser. The present invention concerns a method and related plant for the creation of conductive pigments starting from laser cutting production waste.
I rifiuti speciali sono quei rifiuti che derivano prevalentemente dalle produzioni di tipo industriale e che necessitano di un loro personale percorso ai fini dello smaltimento. A differenza di quelli urbani, che consistono nei rifiuti che buttiamo nei bidoni di casa, che vengono raccolti per le strade o nelle aree pubbliche e quelli vegetali provenienti dalle aree verdi, i rifiuti speciali necessitano interventi di smaltimento particolari e appositi, per la maggior parte delle volte effettuati da privati, come ad esempio i rifiuti derivanti da lavorazione industriali, i rifiuti di attivit? commerciali, i fanghi che derivano dal trattamento delle acque e depurazione delle acque reflue e da abbattimento di fumi, i rifiuti derivanti da attivit? sanitarie o ancora quelli derivanti da macchinari e apparecchiature vecchi o rovinati o da veicoli a motore e rimorchi ormai inutilizzabili. A differenza dei rifiuti urbani, che vengono raccolti e gestiti dalla pubblica amministrazione, lo smaltimento dei rifiuti speciali viene effettuato da un sistema di aziende private; avviene prevalentemente attraverso il recupero di materia, ovvero il riciclo, oppure attraverso lo smaltimento in discarica, l?incenerimento, l?avvio al recupero di energia. Tra i rifiuti speciali va tenuta in considerazione la sottocategoria riguardante i rifiuti pericolosi, che necessitano di un altro tipo di gestione. Vengono considerati rifiuti speciali pericolosi tutti quei rifiuti generati dalle attivit? produttive che contengono al loro interno un?elevata dose di sostanze inquinanti: i rifiuti prodotti dalle industrie manifatturiere o dalle attivit? di trattamento rifiuti e risanamento, cos? come pu? trattarsi anche di scarti derivanti dalla raffinazione del petrolio, dall?industria fotografica, dalle produzioni che utilizzano processi chimici, da solventi, dall?industria metallurgica o da oli esauriti. Nel nostro ambito, le polveri derivanti dal taglio laser, sono considerate rifiuti speciali non pericolosi, poich? non rientrano nelle categorie sopra elencate. Tuttavia, vista la grossa mole di produzione rappresentano un grosso costo pi? che un problema per l?azienda; anche se questi scarti vengono utilizzati in agricoltura come fertilizzante per i campi, ? necessario rimetterli in circolo con nuove funzionalit? e, vista la capacit? superconduttiva di queste polveri metalliche, si ? pensato di riqualificarle al fine di creare delle vernici conduttive, amalgamandole con una soluzione colloidale (quale pu? essere il polivinilacetato oppure amido di mais e aceto che rappresenta un?ottima soluzione home-made) con l?aggiunta di un pigmento nero al fine di uniformare il colore della vernice. A tal proposito potrebbe essere interessante utilizzare la polvere lavica, altra sostanza naturale considerata e trattata come rifiuto speciale, come pigmento per la vernice: nell?abito della nostra invenzione, infatti, rappresenterebbe un?ottima soluzione in quanto, avendo anch?essa propriet? conduttive, non andrebbe ad impattare negativamente sulla conducibilit? della nostra soluzione fungendo, allo stesso tempo, da pigmento, in quanto nera. Special waste is that waste which mainly derives from industrial production and which requires its own personal path for disposal. Unlike urban waste, which consists of waste that we throw in the bins at home, which is collected on the streets or in public areas and plant waste coming from green areas, special waste requires particular and specific disposal interventions, mostly often carried out by private individuals, such as waste resulting from industrial processing, waste from industrial activities? commercial, the sludge deriving from water treatment and purification of waste water and from fume abatement, waste deriving from activities? healthcare or even those resulting from old or ruined machinery and equipment or from motor vehicles and trailers that are no longer usable. Unlike municipal waste, which is collected and managed by the public administration, the disposal of special waste is carried out by a system of private companies; occurs mainly through the recovery of material, i.e. recycling, or through landfill disposal, incineration, or the initiation of energy recovery. Among special waste, the subcategory concerning hazardous waste, which requires another type of management, must be taken into consideration. Are all those wastes generated by activities considered special hazardous waste? productive ones that contain within them a high dose of polluting substances: the waste produced by manufacturing industries or activities of waste treatment and rehabilitation, so? how can? these may also be waste resulting from oil refining, from the photographic industry, from productions that use chemical processes, from solvents, from the metallurgical industry or from spent oils. In our field, the dust resulting from laser cutting is considered non-hazardous special waste, since it is do not fall into the categories listed above. However, given the large amount of production they represent a large cost. what a problem for the company; even if these wastes are used in agriculture as fertilizer for the fields,? Is it necessary to put them back into circulation with new features? and, given the capacity? superconducting of these metal powders, yes? thought of redeveloping them in order to create conductive paints, mixing them with a colloidal solution (which could be polyvinyl acetate or corn starch and vinegar which represents an excellent home-made solution) with the addition of a black pigment in order to uniform the color of the paint. In this regard, it could be interesting to use lava powder, another natural substance considered and treated as special waste, as a pigment for paint: in the context of our invention, in fact, it would represent an excellent solution as, having also properties conductive, wouldn't it have a negative impact on the conductivity? of our solution acting, at the same time, as a pigment, as it is black.
