Estos barnices se utilizan en lugares donde hay una gran cantidad de personas, como centros comerciales, instalaciones de alojamiento, escuelas o cines. Estos lugares deben emitir el Certificado de Prevenci\u00f3n de Incendios (CPI en italiano) para materiales combustibles, como muebles y elementos estructurales (por ejemplo, vigas de madera, acero u hormig\u00f3n).[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][\/vc_column][\/mk_page_section][mk_page_section bg_image_portrait=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/vernici-intumescenti.jpg” bg_position=”right center” bg_repeat=”no-repeat” bg_stretch=”true” enable_3d=”true” bg_video=”yes” mp4=”http:\/\/www.renneritalia.com\/wp-content\/uploads\/video\/shutterstock_v2154200.mp4″ webm=”http:\/\/www.renneritalia.com\/wp-content\/uploads\/video\/shutterstock_v2154200.webm” ogv=”http:\/\/www.renneritalia.com\/wp-content\/uploads\/video\/shutterstock_v2154200.ogv” poster_image=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/vernici-intumescenti.jpg” padding_top=”200″ padding_bottom=”200″ sidebar=”sidebar-1″][vc_column width=”1\/2″][\/vc_column][vc_column width=”1\/2″][vc_column_text el_class=”white rennertitle” css=”.vc_custom_1554661884956{margin-bottom: 0px !important;}”]La diferencia

\ne intumescentes[\/vc_column_text][vc_column_text el_class=”white rennerp” css=”.vc_custom_1555406107303{margin-bottom: 0px !important;}”]La diferencia entre los barnices ign\u00edfugos y los barnices intumescentes es su composici\u00f3n qu\u00edmica. Los primeros contienen aditivos ign\u00edfugos o anti-llama (del lat\u00edn ignis<\/em>, fuego y fugo<\/em>, “que deja escapar”); los \u00faltimos est\u00e1n compuestos con aditivos intumescentes (del lat\u00edn intumescens<\/em>, participio presente de intum\u011bscere<\/em>, o “hincharse”).<\/p>\n

En el caso de temperaturas entre 200\u00b0C y 300\u00b0C, los aditivos ign\u00edfugos liberan sustancias, inhibiendo el ox\u00edgeno: desarrollan di\u00f3xido de carbono o crean vapor de agua, lo que disminuye la temperatura de la combusti\u00f3n. Entre 300\u00b0C y 400\u00b0C, los barnices resistentes al fuego inician el proceso de cristalizaci\u00f3n. Esencialmente, una capa vitrificada no inflamable crea una barrera para la madera.[\/vc_column_text][\/vc_column][\/mk_page_section][mk_page_section bg_image=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/vernici-ignifughe.jpg” bg_image_portrait=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/bk_cicli_mobile.jpg” bg_position=”left center” bg_repeat=”no-repeat” bg_stretch=”true” enable_3d=”true” padding_top=”200″ padding_bottom=”200″ sidebar=”sidebar-1″][vc_column width=”1\/2″][vc_column_text el_class=”white rennertitle” css=”.vc_custom_1554661908348{margin-bottom: 0px !important;}”]Barrera de protecci\u00f3n
\ny aislamiento[\/vc_column_text][vc_column_text el_class=”white rennerp” css=”.vc_custom_1555406138172{margin-bottom: 0px !important;}”]Los aditivos intumescentes reaccionan a una temperatura de 200\u00b0C, hinchando la pel\u00edcula del barniz. De esta manera, crean una barrera protectora y aislante, lo que retrasa tanto la combusti\u00f3n como el aumento de la temperatura. Normalmente, los aditivos ign\u00edfugos se utilizan en ciclos aplicados sobre muebles. Mientras que los aditivos intumescentes m\u00e1s reactivos, que no son muy transparentes, se utilizan en pinturas, que se utilizan para pintar estructuras portantes.
\nPor lo tanto, un barniz ign\u00edfugo, certificado en Clase 1 de Reacci\u00f3n al Fuego, contendr\u00e1 aditivos retardantes de llama y tendr\u00e1 un mejor desempe\u00f1o con respecto a la resistencia qu\u00edmica y la resistencia a la abrasi\u00f3n, mientras que un barniz intumescente, certificado en Clase de Resistencia al Fuego ser\u00e1 m\u00e1s sensible a la humedad y al estr\u00e9s.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][\/vc_column][\/mk_page_section][mk_page_section bg_image=”http:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2019\/03\/smoke-1.jpg” bg_position=”center top” bg_repeat=”no-repeat” bg_stretch=”true” enable_3d=”true” padding_top=”100″ padding_bottom=”200″ sidebar=”sidebar-1″][vc_column width=”1\/6″][\/vc_column][vc_column width=”2\/3″][vc_video host=”self_hosted” mp4=”http:\/\/vernicifirewall.it\/wp-content\/uploads\/video\/BASSI_IT.mp4″ poster_image=”http:\/\/vernicifirewall.it\/wp-content\/uploads\/video\/intervista-bassi.jpg” custom_thumbnail=”true” thumbnail_image=”4302″][mk_padding_divider][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/mk_page_section]\n","protected":false},"excerpt":{"rendered":"
