La vediamo sulle auto, sui muri, sugli elettrodomestici e praticamente su tutto ci\u00f2 che necessita di un rivestimento protettivo o semplicemente per scopi estetici. Le vernici destinate alla protezione del substrato sottostante spesso contengono sostanze chimiche che impediscono alla vernice di prendere fuoco o semplicemente di perdere il colore o di screpolarsi. Spesso le vernici utilizzate per scopi estetici sono disponibili in vari colori, ma non sono necessariamente destinate alla protezione del substrato o a una lunga durata.<\/p><p>Tuttavia, tutte le vernici subiscono un certo invecchiamento nel corso del tempo. Gli agenti atmosferici sulla vernice possono spesso modificarne le propriet\u00e0 rispetto a quelle previste dal produttore. Pu\u00f2 scheggiarsi pi\u00f9 rapidamente, scrostarsi con il calore, perdere colore o creparsi. I diversi cambiamenti di propriet\u00e0 delle vernici nel tempo sono il motivo per cui i produttori offrono una scelta cos\u00ec ampia. Le vernici sono personalizzate per soddisfare le diverse esigenze dei singoli clienti.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d440447 elementor-widget elementor-widget-heading\" data-id=\"d440447\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">IMPORTANZA DEL NANO SCRATCH TEST PER IL CONTROLLO DI QUALIT\u00c0<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-966ab4d elementor-widget elementor-widget-text-editor\" data-id=\"966ab4d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Una delle principali preoccupazioni dei produttori di vernici \u00e8 la capacit\u00e0 del loro prodotto di resistere alle screpolature. Una volta che la vernice inizia a screpolarsi, non riesce a proteggere il substrato su cui \u00e8 stata applicata e quindi non soddisfa il cliente. Ad esempio, se un ramo dovesse colpire la fiancata di un'auto e subito dopo la vernice iniziasse a scheggiarsi, i produttori di vernice perderebbero l'attivit\u00e0 a causa della scarsa qualit\u00e0 della vernice. La qualit\u00e0 della vernice \u00e8 molto importante perch\u00e9 se il metallo sotto la vernice viene esposto pu\u00f2 iniziare ad arrugginirsi o a corrodersi a causa della nuova esposizione.<\/p><p>\u00a0<\/p><p>Ragioni simili valgono per molti altri settori, come le forniture per la casa e l'ufficio, l'elettronica, i giocattoli, gli strumenti di ricerca e altro ancora. Anche se la vernice pu\u00f2 essere resistente alle crepe quando viene applicata per la prima volta ai rivestimenti metallici, le propriet\u00e0 possono cambiare nel corso del tempo quando il campione \u00e8 stato sottoposto agli agenti atmosferici. Per questo motivo \u00e8 molto importante che i campioni di vernice siano testati allo stato di invecchiamento. Sebbene la fessurazione sotto un elevato carico di stress possa essere inevitabile, il produttore deve prevedere l'indebolimento dei cambiamenti nel tempo e la profondit\u00e0 del graffio da a\ufb00ettuare per fornire ai propri consumatori i migliori prodotti possibili.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-1ac4bd1 elementor-reverse-mobile elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"1ac4bd1\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-2deb3a7\" data-id=\"2deb3a7\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-031e9e3 elementor-widget elementor-widget-text-editor\" data-id=\"031e9e3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p style=\"text-align: left;\">OBIETTIVO DI MISURAZIONE<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b0dd119 elementor-widget elementor-widget-text-editor\" data-id=\"b0dd119\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Dobbiamo simulare il processo di graffiatura in modo controllato e monitorato per osservare gli e\ufb00etti del comportamento del campione.

meccanico<\/a> nel <a href=\"https:\/\/nanovea.com\/scratch-tester\/\">Nano Scratch Tester<\/a> consente di simulare molti guasti reali di vernici e rivestimenti duri. Applicando carichi crescenti in modo controllato e strettamente monitorato, lo strumento consente di identificare a quale carico si verificano i guasti. Questo pu\u00f2 essere utilizzato per determinare i valori quantitativi della resistenza ai graffi. \u00c8 noto che il rivestimento testato, in assenza di agenti atmosferici, presenta una prima cricca a circa 22 mN. Con valori pi\u00f9 vicini a 5 mN, \u00e8 chiaro che il periodo di 7 anni ha degradato la vernice.<\/p><p>La compensazione del profilo originale consente di ottenere una profondit\u00e0 corretta durante il graffio e di misurare la profondit\u00e0 residua dopo il graffio. Ci\u00f2 fornisce ulteriori informazioni sul comportamento plastico ed elastico del rivestimento in presenza di un carico crescente. Sia la fessurazione che le informazioni sulla deformazione possono essere di grande utilit\u00e0 per migliorare il rivestimento duro. Le deviazioni standard molto ridotte dimostrano anche la riproducibilit\u00e0 della tecnica dello strumento, che pu\u00f2 aiutare i produttori a migliorare la qualit\u00e0 del loro rivestimento\/vernice dura e a studiare gli effetti degli agenti atmosferici.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-9277cdf elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"9277cdf\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-cbff11b\" data-id=\"cbff11b\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-e348d97 elementor-widget elementor-widget-heading\" data-id=\"e348d97\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Avete un'applicazione simile?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-997e896 elementor-align-justify open-chat elementor-widget elementor-widget-button\" data-id=\"997e896\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-size-sm\" role=\"button\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">DISCUTETE SUBITO CON UN ESPERTO<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-12b64ad elementor-align-justify button-quote elementor-widget elementor-widget-button\" data-id=\"12b64ad\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/nanovea.com\/contact-sales-form\/\" id=\"button-quote-bottom\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">OTTENERE RAPIDAMENTE PREZZI E DETTAGLI<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Nano Scratch &amp; Mar Testing of Paint on Metal Substrate Prepared by SUSANA CABELLO INTRODUCTION Paint with or without hard coat is one of the most commonly used coatings.
