DOMANDA DI BREVETTO PER INVENZIONE INDUSTRIALE DAL TITOLO: PATENT APPLICATION FOR INDUSTRIAL INVENTION WITH THE TITLE:
Smacchiatore per legno Stain remover for wood
Campo dell'Invenzione Field of the Invention
La presente invenzione si riferisce al campo dei prodotti per il trattamento del legno in particolare smacchiatori per le macchie dovute alle presenza di tannini. Stato dell'arte The present invention relates to the field of products for treating wood, in particular stain removers for stains due to the presence of tannins. State of the art
Come è noto gran parte dei legni impiegati in edilizia o più in generale in falegnameria sia a scopo costruttivo (come ad esempio travi e simili) come pure a scopo puramente decorativo (ad esempio pannelli di rivestimento, mobili, accessori ecc.) vanno soggetti a macchie, generalmente nerastre, dovute alla presenza nel legno di tannini. As is known, most of the woods used in construction or more generally in carpentry both for construction purposes (such as beams and the like) as well as for purely decorative purposes (for example cladding panels, furniture, accessories, etc.) are subject to spots, generally blackish, due to the presence of tannins in the wood.
Infatti i tannini, come in generale i fenoli, tendono a formare dei complessi colorati, generalmente nerastri o comunque scuri, con i sali di ferro con cui vengono a contatto. In fact, tannins, like phenols in general, tend to form colored complexes, generally blackish or in any case dark, with the iron salts with which they come into contact.
Per eliminare tali antiestetiche macchie, che possono arrivare a interessare anche i muri o le altre superfici a contatto con I legni macchiati, sono noti vari prodotti contenenti agenti complessanti (ad esempio acido ossalico) in combinazione con solventi e prodotti tensioattivi. To eliminate these unsightly stains, which can also affect walls or other surfaces in contact with stained woods, various products are known containing complexing agents (for example oxalic acid) in combination with solvents and surfactant products.
Nonostante la loro efficacia questi prodotti non soddisfano completamente le esigenze di mercato ed e quindi evidente l’interesse a sviluppare nuovi prodotti per risolvere i problemi suddetti. Despite their effectiveness, these products do not completely satisfy market needs and therefore the interest in developing new products to solve the aforementioned problems is evident.
Breve descrizione delle figure Brief description of the figures
La Fig. 1 (a) e (b) mostra l’effetto pulente di una soluzione secondo l’invenzione. Sommario dell’invenzione Fig. 1 (a) and (b) shows the cleaning effect of a solution according to the invention. Summary of the invention
E’ descritta una soluzione in acqua di acido ossalico che permette la perfetta e rapida eliminazione delle macchie su legno dovute alla presenza tannini. A solution of oxalic acid in water is described which allows the perfect and rapid elimination of stains on wood due to the presence of tannins.
Descrizione dettagliata dell'invenzione Detailed description of the invention
La presente invenzione consente di ovviare agli inconvenienti suddetti, grazie a soluzioni acquose di acido ossalico senza richiedere alcun altro componente. The present invention allows to overcome the aforementioned drawbacks, thanks to aqueous solutions of oxalic acid without requiring any other component.
In particolare le soluzioni acquose secondo la presente invenzione contengono acido ossalico in quantità comprese fra il 5 - 25% calcolato in peso sul peso totale della soluzione. In particular, the aqueous solutions according to the present invention contain oxalic acid in quantities ranging from 5 - 25% calculated by weight on the total weight of the solution.
La preparazione avviene semplicemente sciogliendo l’acido ossalico nell’acqua, eventualmente sotto blando riscaldamento nel caso si vogliano ottenere le soluzioni più concentrate. The preparation takes place simply by dissolving the oxalic acid in the water, possibly under mild heating if you want to obtain more concentrated solutions.
Si noti che non è necessario utilizzare acqua distillata o deionizzata ma si può utilizzare anche l'acqua come comunemente disponibile sia per scopi alimentari che industriali o agricoli . Note that it is not necessary to use distilled or deionized water but you can also use water as commonly available for both food and industrial or agricultural purposes.
La soluzione viene utilizzata semplicemente spruzzandola sulle macchie da eliminare, la loro scomparsa è praticamente immediata e totale (nei casi più ostinati può essere utile ripetere il trattamento dopo asciugatura del trattamento precedente). The solution is used simply by spraying it on the stains to be eliminated, their disappearance is practically immediate and total (in the most stubborn cases it may be useful to repeat the treatment after drying of the previous treatment).
La soluzione secondo la presente invenzione è particolarmente efficace nel caso di legno di latifoglie come ad esempio castagno, rovere e legni simili. The solution according to the present invention is particularly effective in the case of hardwoods such as chestnut, oak and similar woods.
Esempio Example
25 kg di acido ossalico sono stati sciolti in 200 It di acqua sotto blando riscaldamento e la soluzione ottenuta è stata lasciata raffreddare a temperatura ambiente e quindi suddivisa in contenitori spray di varie dimensioni. 25 kg of oxalic acid were dissolved in 200 It of water under gentle heating and the solution obtained was allowed to cool to room temperature and then divided into spray containers of various sizes.
Nella Figura 1 (a e b) è visibile il risultato del trattamento ottenuto spruzzando 50 cc. di una soluzione ottenuta secondo l’esempio 1 su una superficie di castagno con macchie dovute alla presenza di viti di fissaggio in ferro. Figure 1 (a and b) shows the result of the treatment obtained by spraying 50 cc. of a solution obtained according to example 1 on a chestnut surface with stains due to the presence of iron fixing screws.
