Titolo: “METODO DI PRODUZIONE DI PIASTRELLE IN ALLUMINIO DECORATE” Title: "METHOD OF PRODUCTION OF DECORATED ALUMINUM TILES"
Testo della descrizione Description text
La presente invenzione è relativa ad un metodo o processo di produzione di piastrelle in alluminio, in particolare a piastrelle di alluminio decorate. The present invention relates to a method or process for producing aluminum tiles, in particular decorated aluminum tiles.
La possibilità di realizzare pavimentazioni per edifici civili, in particolare piastrelle, dall’elevato valore estetico dipende necessariamente dal tipo di materiali impiegabili per lo scopo ed anche dalla capacità di decorare piastrelle costituite da tali materiali. The possibility of creating flooring for civil buildings, in particular tiles, with a high aesthetic value necessarily depends on the type of materials that can be used for the purpose and also on the ability to decorate tiles made from these materials.
Attualmente risulta particolarmente apprezzato l’uso di materiali metallici per la realizzazione delle piastrelle, con particolare riferimento all’alluminio considerando soprattutto le sue caratteristiche di riflessione della luce. Inoltre la nota lavorabilità di questo materiale consente di riprodurre su piastrelle con esso prodotte decorazioni di ogni genere, volte ovviamente ad aumentarne ulteriormente il pregio estetico. Currently, the use of metal materials for making tiles is particularly appreciated, with particular reference to aluminum, especially considering its light reflection characteristics. Furthermore, the well-known workability of this material makes it possible to reproduce decorations of all kinds on tiles produced with it, obviously aimed at further increasing their aesthetic value.
Tuttavia nella realizzazione di prodotti del genere sopra descritto è necessario far fronte ad alcune difficoltà tecniche che insorgono nella fase produttiva, come: ripetibilità della decorazione su un gran numero di piastrelle ma anche flessibilità nella scelta del particolare motivo da applicare, protezione del materiale dall’attacco di agenti chimici così come dall’azione meccanica di un qualsiasi corpo a contatto con dette piastrelle. However, in the realization of products of the kind described above it is necessary to face some technical difficulties that arise in the production phase, such as: repeatability of the decoration on a large number of tiles but also flexibility in the choice of the particular motif to be applied, protection of the material from attack by chemical agents as well as by the mechanical action of any body in contact with said tiles.
Scopo della presente invenzione è allora quello di prevedere un metodo di produzione di piastrelle in alluminio decorate che consenta di ottenere un prodotto finale non soggetto all’usura meccanica o all’attacco chimico che causerebbero non solo la perdita parziale o totale della decorazione ma anche il degrado strutturale del prodotto stesso. The purpose of the present invention is therefore to provide a method of producing decorated aluminum tiles that allows to obtain a final product not subject to mechanical wear or chemical attack which would cause not only the partial or total loss of the decoration but also the structural degradation of the product itself.
Ulteriore scopo della presente invenzione è anche quello di prevedere un metodo di produzione di piastrelle in alluminio decorate in cui la decorazione può comprendere una qualsiasi geometria e può essere applicata singolarmente su ciascuna piastrella così come su un gruppo di piastrelle, qualora detta decorazione presentasse misure maggiori di quelle della singola piastrella. A further object of the present invention is also to provide a method of producing decorated aluminum tiles in which the decoration can include any geometry and can be applied individually on each tile as well as on a group of tiles, should said decoration have larger sizes. than those of the single tile.
Verrà ora fornita una descrizione dettagliata del metodo di produzione di piastrelle in alluminio decorate in conformità della presente invenzione, alla lettura della quale risulterà chiaro il modo in cui detto metodo supera le difficoltà tecniche descritte in precedenza. A detailed description will now be given of the method of producing decorated aluminum tiles in accordance with the present invention, upon reading which it will become clear how said method overcomes the technical difficulties described above.
Il processo produttivo in conformità della presente invenzione prevede l’impiego di materiale in lega di alluminio di prima scelta, come ad esempio le leghe denominate secondo la classificazione UNI con EN-AW 5005 o EN-AW 6082 o ancora EN-AW 5308, tagliato in fogli con formati predefiniti ed una tolleranza inferiore o al più uguale a ±0.1mm rispetto sia alle misure di taglio che allo spessore del fogli stessi che andranno a costituire le piastrelle prodotte. The production process in accordance with the present invention provides for the use of first choice aluminum alloy material, such as alloys named according to the UNI classification with EN-AW 5005 or EN-AW 6082 or EN-AW 5308, cut in sheets with predefined formats and a tolerance lower than or at most equal to ± 0.1mm with respect to both the cutting measures and the thickness of the sheets themselves that will make up the tiles produced.
A questo punto, note le dimensioni delle piastrelle, il motivo o la decorazione — prodotti con programmi informatici di grafica o anche a mano libera e successivamente digitalizzati — vengono acquisiti su supporto informatico durante la fase di modellazione CAD che permette la successiva conversione nel formato CAM del motivo o della decorazione interpretabile da una macchina a controllo numerico ad asportazione di truciolo. E evidente quindi che la realizzazione del motivo su ciascuna piastrella non dipenderà più dall’abilità dell’operatore addetto alla lavorazione e quindi sarà garantita la ripetibilità dell’operazione per ogni piastrella prodotto. Inoltre, la fase appena descritta consente anche di raggiungere la modalità in affiancamento, ovvero si potrà realizzare un unico motivo su una pluralità di piastrelle — tenendo ovviamente in conto quale sarà la disposizione di detta pluralità — e non solo un unico motivo su una singola piastrella. At this point, once the dimensions of the tiles are known, the motif or decoration - produced with computer graphics programs or even freehand and subsequently digitized - are acquired on computer support during the CAD modeling phase which allows the subsequent conversion into the CAM format of the motif or decoration that can be interpreted by a numerical control machine with chip removal. It is therefore evident that the realization of the pattern on each tile will no longer depend on the skill of the operator in charge of the processing and therefore the repeatability of the operation will be guaranteed for each tile produced. Furthermore, the phase just described also allows to reach the side-by-side mode, i.e. a single motif can be created on a plurality of tiles - obviously taking into account the arrangement of said plurality - and not just a single motif on a single tile. .
Tuttavia l’applicazione del motivo non può realizzarsi prima dell’esecuzione di una terza fase che prevede lavorazioni per asportazione di truciolo atte ad ottenere una desiderata planarità così come la totale eliminazione di rigature, macchie ed in genere sporcizia che possano compromettere l’estetica del prodotto finale. Fra dette lavorazioni si intende compresa anche la smussatura degli spigoli di ciascuna piastrella. Al termine delle suddette lavorazioni la piastrella è pronta per essere decorata: viene perciò fissata su una macchina CNC — tipicamente frese a placchette e/o frese in metallo duro integrale — per la creazione di micro-rigature sulla superficie della piastrella dando forma al motivo desiderato ottenendo così importanti giochi di luce. However, the application of the pattern cannot be carried out before the execution of a third phase which involves machining by chip removal suitable for obtaining a desired flatness as well as the total elimination of scratches, stains and in general dirt that could compromise the aesthetics of the final product. Said processing also includes the chamfering of the edges of each tile. At the end of the aforementioned processes, the tile is ready to be decorated: it is therefore fixed on a CNC machine - typically milling cutters and / or solid carbide cutters - to create micro-scratches on the surface of the tile, giving shape to the desired pattern. thus obtaining important plays of light.
Ciascuna piastrella attraversa poi la fase di anodizzazione o ossidazione anodica che permette di preservare l’alluminio che le costituisce dalla corrosione, com’è noto agli esperti del settore. In base a specifiche richieste è possibile effettuare una anodizzazione dura o naturale. Each tile then goes through the anodization or anodic oxidation phase which allows to preserve the aluminum that constitutes it from corrosion, as is known to experts in the field. Based on specific requests, it is possible to carry out a hard or natural anodizing.
La fase successiva all’anodizzazione è quella della colorazione delle singole piastrelle in maniera conforme al motivo ed in modo da rispettare il grado di resistenza ai raggi UV, generalmente compreso in un intervallo da 6 ad 8 nella scala di resistenza UV, garantendone di conseguenza la durata nel tempo. La colorazione può essere effettuata con differenti tecniche comprendenti: uso di pigmenti organici o inorganici, elettrocolorazione e colorazione per interferenza. The next step after anodizing is that of coloring the individual tiles in accordance with the pattern and in order to respect the degree of resistance to UV rays, generally included in a range from 6 to 8 on the UV resistance scale, consequently guaranteeing their duration over time. The coloring can be carried out with different techniques including: use of organic or inorganic pigments, electro-coloring and interference coloring.
L’ultima fase del processo produttivo in conformità della presente invenzione è l’applicazione di una sostanza chimica indurente sulla superficie della piastrella volta ad aumentarne ulteriormente la resistenza all’abrasione, all’aggressione di agenti chimici come acidi, candeggina o ammoniaca oltreché la resistenza contro i raggi UV. Detta sostanza chimica può essere una qualsiasi che comprenda: silani modificati epossi, silanizzati silani, poliazani, polisilani, azani epossi, metossi silani, silani uretanizzati. The last phase of the production process in accordance with the present invention is the application of a hardening chemical substance on the surface of the tile aimed at further increasing its resistance to abrasion, to the aggression of chemical agents such as acids, bleach or ammonia as well as the resistance against UV rays. Said chemical substance can be any which includes: modified epoxy silanes, silanized silanes, polyazanes, polysilanes, epoxy azanes, methoxy silanes, urethanized silanes.
Com’è immediato ricavare dalla descrizione dettagliata appena fornita, l’ultima fase di produzione, ovvero il trattamento con sostanze chimiche indurenti, rappresenta di fatto la soluzione al problema inizialmente posto, ovvero l’adattabilità dell’alluminio, o delle sue leghe, all’uso come piastrella che lo porta certamente all’aggressione chimica durante, ad esempio, la pulizia del pavimento o anche all’abrasione dovuta al passaggio di persone e/o cose su di esso. L’assenza di una adeguata protezione in queste condizioni porterebbe infatti, se non al degrado funzionale della piastrella, certamente a quello estetico annullando di fatto la ragione per cui una piastrella di questo genere viene prodotta. As it is immediate to deduce from the detailed description just provided, the last stage of production, that is the treatment with hardening chemicals, represents in fact the solution to the problem initially posed, that is the adaptability of aluminum, or its alloys, to the 'use as a tile that certainly leads to chemical aggression during, for example, cleaning the floor or even abrasion due to the passage of people and / or things on it. The absence of adequate protection in these conditions would in fact lead, if not to the functional degradation of the tile, certainly to the aesthetic one, effectively canceling the reason why a tile of this kind is produced.
