Description
Il presente trovato ha come oggetto un procedimento per ridurre l'adesione del calcare a componenti di rubinetteria, particolarmente per impianti igienico-sanitari. The present invention relates to a process for reducing the adhesion of limestone to tap components, particularly for sanitary installations.
Come è noto, uno dei principali problemi riscontrabili nell'uso di componenti di rubinetteria, in particolare in zone nelle quali la rete idrica è alimentata con acque di elevata durezza, è rappresentato dai depositi di calcare che si formano sulle parti dei componenti di rubinetteria che vengono a contatto con l'acqua a seguito dell'evaporazione dell'acqua. I depositi di calcare riducono progressivamente la sezione di passaggio dell'acqua penalizzando l'efficienza del componente fino a comprometterne il funzionamento ed impongono interventi di manutenzione, tanto più frequenti quanto maggiore è la durezza dell'acqua, per rimuoverli e ripristinare il corretto funzionamento del componente. As is known, one of the main problems encountered in the use of faucet components, in particular in areas where the water network is supplied with water of high hardness, is represented by limescale deposits that form on the parts of the faucet components that come into contact with water as a result of the evaporation of the water. The limescale deposits progressively reduce the water passage section, penalizing the efficiency of the component up to compromising its functioning and requiring maintenance interventions, the more frequent the greater the hardness of the water, to remove them and restore the correct functioning of the component.
Questo problema è particolarmente pesante negli erogatori di acqua che suddividono il flusso di acqua in.numerosi getti di ridotto diametro, come ad esempio in rompigetti, aeratori, erogatori a soffioni per docce, nei quali i singoli passaggi, avendo un piccolo diametro, vengono rapidamente intasati dai depositi calcarei, ma è comunque presente anche in altri componenti di rubinetteria. This problem is particularly serious in water dispensers that divide the flow of water into numerous small diameter jets, such as for example in jets, aerators, shower heads for showers, in which the individual passages, having a small diameter, are quickly clogged with limestone deposits, but it is also present in other faucet components.
I depositi di calcare, oltre ad avere un effetto negativo sul funzionamento del componente di rubinetteria, alterano notevolmente l'estetica del componente conferendogli un aspetto trascurato e vetusto e, per la loro natura porosa, favoriscono il deposito di germi e di sporco compromettendo anche l'igienicità del componente. Limescale deposits, in addition to having a negative effect on the functioning of the faucet component, significantly alter the aesthetics of the component, giving it a neglected and old-fashioned appearance and, due to their porous nature, favor the deposition of germs and dirt, also compromising the hygiene of the component.
La rimozione del calcare, particolarmente quando l'elevata durezza dell'acqua è abbinata ad una pulizia specifica poco frequente, non è di facile attuazione in quanto l'utilizzo di prodotti acidi per provocare il suo scioglimento può avere effetti dannosi sul componente di rubinetteria alterando l'integrità di rivestimenti con finalità estetiche, come ad esempio le cromature, particolarmente sensibili agli acidi. The removal of limescale, particularly when the high hardness of the water is combined with an infrequent specific cleaning, is not easy to implement as the use of acid products to cause its dissolution can have harmful effects on the faucet component by altering the integrity of coatings with aesthetic purposes, such as chrome plating, which are particularly sensitive to acids.
Per risolvere questi problemi, sono stati proposti componenti di rubinetteria nei quali le parti dei componenti maggiormente esposte al fenomeno del deposito di calcare sono realizzate in materiali speciali, come ad esempio gomme siliconiche, dai quali risulta più agevole operare il distacco del calcare. To solve these problems, faucet components have been proposed in which the parts of the components most exposed to the phenomenon of limescale deposit are made of special materials, such as silicone rubbers, from which it is easier to remove the limestone.
Questo accorgimento, benché agevoli sensibilmente l'operazione di rimozione del calcare, non risolve pienamente il problema in quanto non ostacola l'accumulo progressivo del calcare e quindi impone comunque l'esecuzione di interventi periodici per operare la sua rimozione e per ripristinare la funzionalità del componente di rubinetteria. This expedient, although considerably facilitates the limescale removal operation, does not fully solve the problem as it does not hinder the progressive accumulation of limestone and therefore requires the execution of periodic interventions to operate its removal and to restore the functionality of the limestone. faucet component.
L'esecuzione di parti in materiali speciali può, inoltre, complicare notevolmente la realizzazione e l'assemblaggio del componente di rubinetteria innalzando sensibilmente il suo costo di produzione. The execution of parts in special materials can also considerably complicate the production and assembly of the tap component, significantly increasing its production cost.
Inoltre, benché il distacco del calcare risulti facilitato, l'asportazione del calcare può risultare difficoltosa in quanto i pezzi di calare distaccato possono restare intrappolati nel componente di rubinetteria ostacolando comunque il corretto flusso dell'acqua. Furthermore, although limescale detachment is facilitated, limescale removal can be difficult as the detached pieces of lowering can remain trapped in the tap component, however hindering the correct flow of water.
In aggiunta, l'esecuzione delle parti del componente di rubinetteria in materiali speciali, come ad esempio gomme siliconiche, che per ottenere il distacco del calcare devono essere deformate con un'azione meccanica, può ridurre sensibilmente la durata complessiva del componente di rubinetteria. In addition, the execution of the parts of the faucet component in special materials, such as silicone rubbers, which must be deformed by a mechanical action to obtain the limescale detachment, can significantly reduce the overall life of the faucet component.
Compito precipuo del presente trovato è quello di risolvere i problemi sopra esposti, escogitando un procedimento che riduca sensibilmente il grado di adesione del calcare a componenti di rubinetteria e favorisca il suo distacco dal componente di rubinetteria durante il suo normale uso, rendendo superflui interventi per la sua rimozione o comunque rendendo notevolmente più semplici e rapidi questi interventi . The main aim of the present invention is to solve the above problems, devising a procedure which significantly reduces the degree of adhesion of limestone to faucet components and favors its detachment from the faucet component during its normal use, making unnecessary interventions for the its removal or in any case making these interventions considerably simpler and faster.
Nell'ambito di questo compito, uno scopo del trovato è quello di proporre un procedimento che non complichi la struttura del componente di rubinetteria in modo tale da non incrementare, in modo sensibile, i suoi costi di produzione. Within the scope of this aim, an object of the invention is to propose a method which does not complicate the structure of the tap component in such a way as not to significantly increase its production costs.
Un altro scopo del trovato è quello di proporre un procedimento che possa essere attuato in modo semplice, compatibile con le usuali tecniche di produzione dei componenti di rubinetteria. Another object of the invention is to propose a method which can be carried out in a simple way, compatible with the usual manufacturing techniques for tap components.
Un ulteriore scopo del trovato è quello di proporre un procedimento che possa essere applicato ad una svariata gamma di componenti di rubinetteria, come ad esempio rompigetti, aeratori, economizzatori, limitatori di flusso, erogatori a doccia, a soffione, erogatori multifunzione, eccetera, sia in materiale metallico che in materiale sintetico . A further object of the invention is to propose a method which can be applied to a various range of faucet components, such as for example jets breakers, aerators, economizers, flow limiters, shower dispensers, shower heads, multifunction dispensers, etc. in metal and synthetic material.
Questo compito, nonché questi ed altri scopi che meglio appariranno in seguito, sono raggiunti da un procedimento per ridurre l'adesione del calcare a componenti di rubinetteria, particolarmente per impianti igienico-sanitari, caratterizzato dal fatto di consistere nel rivestire le parti del componente di rubinetteria, suscettibili di venire a contatto con l'acqua, con uno strato di materiale antiaderente. This task, as well as these and other purposes which will appear better later, are achieved by a process for reducing the adhesion of limestone to faucet components, particularly for sanitary systems, characterized by the fact that it consists in coating the parts of the component of taps, susceptible to contact with water, with a layer of non-stick material.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, del procedimento secondo il trovato, illustrata, a titolo indicativo e non limitativo, qui di seguito. Further characteristics and advantages of the invention will become clearer from the description of a preferred, but not exclusive, embodiment of the method according to the invention, illustrated hereinafter, by way of non-limiting example.
Il procedimento consiste sostanzialmente nel rivestire le parti del componente di rubinetteria, suscettibili di venire a contatto con l'acqua, con uno strato di materiale antiaderente. The process basically consists in coating the parts of the tap component, which are likely to come into contact with water, with a layer of non-stick material.
Tale materiale antiaderente è preferibilmente costituito da PTFE (politetrafluoroetilene) e può essere applicato al componente di rubinetteria mediante processi noti di rivestimento che utilizzano il PTFE per il rivestimento di altri prodotti, come ad esempio apparecchi di cottura o componenti meccanici nei quali il PTFE è utilizzato generalmente per ridurre l'attrito tra due organi in contatto reciproco. In particolare, il PTFE può essere applicato alla superficie del componente di rubinetteria da rivestire mediante processi di verniciatura a spruzzo, a rullo, o per immersione. This non-stick material is preferably made of PTFE (polytetrafluoroethylene) and can be applied to the tap component by known coating processes that use PTFE for coating other products, such as cooking appliances or mechanical components in which PTFE is used. generally to reduce the friction between two members in mutual contact. In particular, PTFE can be applied to the surface of the faucet component to be coated by means of spray, roller, or dip painting processes.
Preferibilmente, lo spessore dello strato di PTFE è sostanzialmente compreso tra 2 μm e 50 μm . Preferably, the thickness of the PTFE layer is substantially comprised between 2 μm and 50 μm.
L'applicazione dello strato di materiale antiaderente secondo il trovato può essere eseguita su componenti di rubinetteria realizzati in metallo, come ad esempio alluminio e sue leghe, rame e sue leghe, ferro e sue leghe, oppure su componenti realizzati in materiale sintetico. The application of the layer of non-stick material according to the invention can be performed on components of taps made of metal, such as for example aluminum and its alloys, copper and its alloys, iron and its alloys, or on components made of synthetic material.
In pratica, l'applicazione dello strato di materiale antiaderente, in particolare PTFE, secondo il trovato, non ostacola il deposito del calcare sulle parti rivestite, a seguito dell'evaporazione dell'acqua da tali parti quando viene interrotto il flusso dell'acqua, ma riduce notevolmente il grado di adesione del calcare a queste parti rivestite. Il grado di adesione del calcare che si ottiene con il procedimento in oggetto è talmente basso che il normale flusso dell'acqua su queste parti, in occasione di un utilizzo successivo del componente di rubinetteria, è di per sé sufficiente a provocare il distacco e la rimozione pressoché totale del calcare depositatosi tra un utilizzo e l'utilizzo successivo. In practice, the application of the layer of non-stick material, in particular PTFE, according to the invention, does not hinder the deposit of limestone on the coated parts, following the evaporation of the water from these parts when the water flow is interrupted, but considerably reduces the degree of adhesion of the limestone to these coated parts. The degree of adhesion of the limestone obtained with the procedure in question is so low that the normal flow of water on these parts, on the occasion of a subsequent use of the tap component, is in itself sufficient to cause detachment and almost total removal of limescale deposited between one use and the next use.
In questo modo, il procedimento secondo il trovato evita, o almeno rallenta notevolmente, l'accumulo progressivo di calcare sulle parti del componente di rubinetteria che vengono a contatto con l'acqua mantenendo praticamente inalterata nel tempo la funzionalità e l'estetica del componente di rubinetteria. In this way, the method according to the invention avoids, or at least significantly slows down, the progressive accumulation of limescale on the parts of the faucet component that come into contact with water, while maintaining the functionality and aesthetics of the fitting component practically unchanged over time. taps.
Inoltre, la ridotta adesione del calcare sul componente di rubinetteria che si ottiene con il procedimento secondo il trovato rende estremamente semplici e rapidi eventuali interventi di pulizia periodica del componente, senza richiedere l'utilizzo di sostanze aggressive o di azioni meccaniche che potrebbero danneggiare il componente. Furthermore, the reduced adhesion of the limestone to the tap component obtained with the method according to the invention makes any periodic cleaning of the component extremely simple and rapid, without requiring the use of aggressive substances or mechanical actions that could damage the component. .
Si è in pratica constatato come il procedimento secondo il trovato assolva pienamente il compito prefissato in quanto riduce sensibilmente il grado di adesione del calcare al componente di rubinetteria e favorisce il suo distacco dal componente di rubinetteria durante il normale uso, rendendo superflui interventi per la sua rimozione o comunque rendendo estremamente semplici e rapidi questi interventi. In practice it has been found that the method according to the invention fully achieves the intended aim as it significantly reduces the degree of adhesion of the limestone to the tap component and favors its detachment from the tap component during normal use, making unnecessary interventions for its removal or in any case making these interventions extremely simple and rapid.
Il procedimento, così concepito, è suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo; inoltre, tutti i dettagli potranno essere sostituiti da altri elementi tecnicamente equivalenti. The process thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; moreover, all the details can be replaced by other technically equivalent elements.
