DESCRIZIONE DESCRIPTION
E' noto che nella pratica dello sci e dello snowboard, la scorrevolezza viene migliorata applicando dei prodotti a base di paraffina o cera, detti scioline, sulla superfìcie inferiore degli sci e degli snowboard stessi, le così dette solette. It is known that in the practice of skiing and snowboarding, smoothness is improved by applying paraffin or wax-based products, called waxes, on the lower surface of the skis and snowboards themselves, the so-called insoles.
La funzione di tali prodotti, è quella di trasformare l'attrito che si crea nello sfregamento tra gli sci e la neve, in energia termica che fonde i cristalli di neve trasformandoli in acqua, in tal modo lo sci scorre sull'acqua anziché sui cristalli , molto più abrasivi e quindi meno scorrevoli. Per fare in modo che questa parte d'acqua si divida in piccole microsfere che scorrano tra lo sci e la neve, aumentando ulteriormente la scorrevolezza, è uso comune creare sulla soletta dello sci una serie continua di microsolchi che direzioni Il flusso delle microsfere d'acqua, in modo da sfruttare appieno la loro proprietà volvente per tutta la lunghezza delio sci. Questo tipo di lavorazione a microsolchi viene comunemente chiamata impronta. The function of these products is to transform the friction that is created in the friction between the skis and the snow, into thermal energy that melts the snow crystals, transforming them into water, in this way the ski runs on the water instead of on the crystals. , much more abrasive and therefore less smooth. To ensure that this part of the water is divided into small microspheres that flow between the ski and the snow, further increasing the smoothness, it is common to create a continuous series of micro-grooves on the ski sole that direct the flow of the microspheres. water, in order to take full advantage of their rolling properties along the entire length of the ski. This type of micro groove processing is commonly called imprint.
E' anche noto che a seconda della temperatura della neve e dell'aria e a seconda dell'umidità, è necessario usare la appropriata sciolina , ed è anche noto che anche pochi gradi centigradi di differenza consigliano di cambiare sciolina per avere il massimo della prestazione. Normalmente, scioline più dure si adattano meglio a nevi più fredde, e sdoline più tenere a nevi più calde. Altrettanto vale per l'impronta: al cambiare delle caratteristiche della neve si usa cambiare il tipo di microsolco che compone il disegno dell'Impronta stessa, microsolchi molto piccoli, fìtti e poco profondi si adattano molto bene a nevi fredde ed asciutte, microsolchi più grandi, più distanti tra loro e profondi si adattano meglio a nevi più calde e umidità più elevate. It is also known that depending on the snow and air temperature and depending on the humidity, it is necessary to use the appropriate wax, and it is also known that even a few degrees Celsius of difference recommend changing the wax for maximum performance. Normally, harder waxes are better suited to colder snows, and softer waxes to warmer snows. The same is true for the footprint: when the characteristics of the snow change, the type of micro furrow that makes up the design of the footprint itself changes, very small, thick and shallow micro-furrows adapt very well to cold and dry snow, larger micro-furrows , more distant from each other and deeper they adapt better to warmer snows and higher humidity.
Per avere uno sci o uno snowboard veloce è quindi necessario riuscire a controllare la quantità d'acqua prodotta dall'attrito tra sci e neve con la sciolina, e la sua dispersione in mìcrosfere al disotto dello sci con la giusta direzione e con la giusta scorrevolezza, in modo da farlo scorrere su una sorta di tappeto di sfere d'acqua, l'effetto di un enorme cuscinetto a sfere. To have a fast ski or snowboard it is therefore necessary to be able to control the amount of water produced by the friction between ski and snow with the wax, and its dispersion in micro-sphere under the ski with the right direction and with the right smoothness. , so as to slide it on a sort of carpet of water balls, the effect of a huge ball bearing.
Il principale problema del binomio sciolina- impronta, è quello di riuscire a trattenere la giusta quantità di microsfere d'acqua, in funzione della quantità di acqua prodotta dalla fusione dei cristalli di neve, della velocità che si raggiunge e della massa che grava sulla superficie dell'impronta stessa. E' molto difficile raggiungere un rapporto corretto tra questi tre parametri, perché le condizioni di utilizzo variano in modo continuo, ad esempio il carico applicato all'Impronta varia ad ogni cambio di pendenza; ad ogni sua variazione infatti, corrisponde un cambio della velocità che comporta il cambiamento negli attriti e quindi una diversa quantità d'acqua. The main problem of the wax-footprint binomial is to be able to retain the right amount of water microspheres, depending on the amount of water produced by the melting of the snow crystals, the speed that is reached and the mass weighing on the surface. of the footprint itself. It is very difficult to reach a correct ratio between these three parameters, because the conditions of use vary continuously, for example the load applied to the Footprint varies with each change of slope; in fact, each variation corresponds to a change in speed which involves a change in friction and therefore a different quantity of water.
Con le scioline convenzionali la produzione d'acqua deve essere proporzionata alia capacità idrorepellente della sciolina: se la trasformazione del cristallo in acqua è scarsa, l'attrito meccanico tra la neve e la soletta rallenta lo sci; se l'effetto idrorepellente è scarso, la troppa acqua sotto allo sci forma un film continuo che crea un effetto ventosa che rallenta lo sci. Succede quindi che uno sci molto scorrevole in determinate condizioni al solo variare di pochi gradi centigradi della neve e/o dell'aria, accusi dei vistosi peggioramenti nella scorrevolezza. With conventional waxes, the production of water must be proportionate to the water-repellent capacity of the wax: if the transformation of the crystal into water is poor, the mechanical friction between the snow and the base slows down the ski; if the water repellent effect is poor, too much water under the ski forms a continuous film that creates a suction effect that slows down the ski. It therefore happens that a very smooth ski in certain conditions, just by varying the snow and / or air by a few degrees centigrade, accuses of noticeable worsening in smoothness.
E' noto altresì che quasi tutte le aziende produttrici di scioline, per risolvere questo problema, aggiungono alle paraffine che compongono le scioline dei composti fluorurati, i quali per le loro qualità idrorepellenti, superiori alle paraffine, aumentano la scorrevolezza tra sci e particelle d'acqua. Tale principio di arricchimento, seppur con materiali diversi, viene seguito anche nella costruzione delie solette, li polimero che le compone, viene arricchito con una piccola percentuale di grafite, che ne aumenta le caratteristiche di scorrevolezza. It is also known that almost all wax manufacturers, to solve this problem, add fluorinated compounds to the paraffins that make up the waxes, which due to their water-repellent qualities, superior to paraffins, increase the smoothness between skis and particles of water. This enrichment principle, albeit with different materials, is also followed in the construction of the insoles, the polymer that composes them, is enriched with a small percentage of graphite, which increases its smoothness characteristics.
Ho verificato che con l'uso combinato di particolari prodotti anch'essi con proprietà idrorepellenti, dosati in modo conveniente, si raggiungono compromessi molto vantaggiosi tra attriti necessari a sciogliere la neve e idrorepellenza per agevolare la scorrevolezza, in modo da ampliare sensibilmente lo spettro d'impiego del materiale in base alle temperature di aria e neve. I have verified that with the combined use of particular products also with water-repellent properties, dosed in a convenient way, very advantageous compromises are reached between the friction necessary to melt the snow and water repellency to facilitate smoothness, in order to significantly broaden the spectrum of '' use of the material based on the temperatures of air and snow.
Ho anche verificato che l'uso corretto di tali materiali in particolari rapporti , combinati con un materiale di supporto che li ancori alla soletta degli sci e degli snowboard, consente di raggiungere ulteriori notevoli miglioramenti nelle prestazioni di scorrevolezza degli stessi, nel più ampio spettro d'impiego, nonché nella durata delle stesse prestazioni. I have also verified that the correct use of these materials in particular ratios, combined with a support material that anchors them to the base of skis and snowboards, allows to achieve further notable improvements in their gliding performance, in the broadest spectrum of use, as well as in the duration of the same services.
Ho verificato che l'uso di particolari prodotti idrorepellenti vantaggiosamente usati per rivestire le solette di sci e snowboard, e/o all'interno del materiale che compone le stesse solette, dosati nel modo più conveniente, permettono di raggiungere un compromesso ottimale tra attrito ed idrorepellenza e caratteristiche tali da potersi adattare a più ampie differenze di temperatura e di umidità. I have verified that the use of particular water-repellent products advantageously used to coat the insoles of skis and snowboards, and / or within the material that makes up the same insoles, dosed in the most convenient way, allow to reach an optimal compromise between friction and water repellency and characteristics such as to be able to adapt to wider differences in temperature and humidity.
In particolare l'uso dei fullereni e/o nano diamonds, sitano e/o suoi derivati, silica-fumed e/o nano ceramics e dei composti fluorurati, variamente legati alla soletta, combinati in proporzioni dipendenti da temperatura e umidità, conferisce notevole costanza e continuità neila prestazione, compensando, gli uni, i deficit degli altri. In particular, the use of fullerenes and / or nano diamonds, sitano and / or its derivatives, silica-fumed and / or nano ceramics and of fluorinated compounds, variously linked to the base, combined in proportions depending on temperature and humidity, gives considerable constancy and continuity in the performance, compensating, on the one hand, the deficits of the others.
Si verifica quindi che nel momento in cui le qualità di scorrevolezza garantite dai fluorurati vengono a mancare, il silano ed il silica fumed e/o nano ceramics le compensano e via via quando decadono le caratteristiche di scorrevolezza anche di questi, intervengono i fullereni e/o nano diamonds. It therefore occurs that when the smoothness qualities guaranteed by the fluorinates are lacking, the silane and silica fumed and / or nano ceramics compensate them and gradually when the smoothness characteristics of these also decay, the fullerenes and / or or nano diamonds.
Considerando le qualità di ognuno dei materiali sopracitati, ho messo a punto nuove soluzioni e trattamenti che vanno a migliorare e/o sostituire vantaggiosamente i tradizionali sistemi di sciolinatura. Considering the qualities of each of the materials mentioned above, I have developed new solutions and treatments that improve and / or advantageously replace the traditional waxing systems.
Un esempio esplicativo non limitativo della presente invenzione è dato dall' applicazione di una soluzione di liquido polimerizzante con all'interno una dispersione, di fullereni e/o nano diamonds, siiano e/o suoi derivati, silica-fumed e/o nano ceramics, composti fluorurati, singolarmente o in combinazione tra loro, in percentuale complessiva in peso equivalente o superiore allo 0,0001% ; il rapporto tra i vari componenti viene calcolato in base aN'umidità , alla temperatura della neve ed alla temperatura dell'aria. A non-limiting explanatory example of the present invention is given by the application of a solution of polymerizing liquid with a dispersion inside, of fullerenes and / or nano diamonds, siiano and / or its derivatives, silica-fumed and / or nano ceramics, fluorinated compounds, individually or in combination with each other, in an overall weight percentage equivalent to or greater than 0.0001%; the ratio between the various components is calculated on the basis of humidity, snow temperature and air temperature.
Considerando le qualità di ognuno dei materiali sopracitati, ho messo a punto inoltre nuove tecniche di deposizione degli stessi sullo sci e snowboard che migliorano e possono sostituire vantaggiosamente le tecniche tradizionali. Considering the qualities of each of the aforementioned materials, I have also developed new techniques for depositing them on skis and snowboards that improve and can advantageously replace traditional techniques.
Un esempio esplicativo di tali nuove tecniche non limitativo della presente invenzione è quello di usare gli stessi materiali secondo i principi già descritti, depositandoli sullo sci con tecniche a plasma atmosferico , a radio frequenza (Plasma RF) o a micro onde (Plasma MW). An illustrative example of these new non-limiting techniques of the present invention is that of using the same materials according to the principles already described, depositing them on the ski with atmospheric plasma, radio frequency (Plasma RF) or micro wave (Plasma MW) techniques.
Considerando le qualità di ognuno dei materiali sopracitati, ho messo a punto inoltre nuove soluzioni costruttive della soletta che possono sostituire vantaggiosamente quelle tradizionali. Considering the qualities of each of the aforementioned materials, I have also developed new construction solutions for the insole that can advantageously replace the traditional ones.
Un esempio esplicativo di tali soluzioni non limitativo della presente invenzione è dato dalla dispersione degli stessi materiali , singolarmente o in combinazione tra loro in percentuale complessiva in peso equivalente o superiore allo 0,0001% , nel materiale che compone la soletta dello sci o dello snowboard, potendo detta soletta essere ulteriormente trattata anche secondo quanto in precedenza descritto. An illustrative example of such non-limiting solutions of the present invention is given by the dispersion of the same materials, individually or in combination with each other in a total percentage by weight equivalent to or greater than 0.0001%, in the material that makes up the sole of the ski or snowboard. , said insole being able to be further treated also according to what was previously described.
