Nous avons mis l\u2019accent dans la section de Tecwool\u00ae<\/sup> F <\/strong>sur l\u2019importance de la protection dans les tunnels. On s\u2019est adapt\u00e9 aux exigences normatives de nombreux pays avec le Tecwool\u00ae<\/sup> 825<\/strong>. Test\u00e9 selon Protocole RWS\/Efectis \u201cR\u00e9sistance au feu des rev\u00eatements qui prot\u00e8gent le b\u00e9ton\u201d et soumis aux \u00a0courbes de feu RWS et Hydrocarbures Pond\u00e9r\u00e9e de fa\u00e7on combin\u00e9e. Pendant les trois heures du test de maximums, la temp\u00e9rature dans la surface du b\u00e9ton a \u00e9t\u00e9 de 201\u00ba, bien en dessous de la limite maximale de protocole situ\u00e9e \u00e0 380\u00ba dans la surface ou de 250\u00ba dans les renforts en acier. Cela a d\u00e9montr\u00e9 la grande puissance d\u2019isolement du Tecwool\u00ae<\/sup> 825<\/strong>.<\/p>\n
Une autre aspect fondamental du Tecwool\u00ae\u00a0<\/sup>825<\/strong> est sa grande capacit\u00e9 d\u2019adh\u00e9rence sur le b\u00e9ton et l\u2019acier et sa finition monolithe, en \u00e9vitant l\u2019apparition de fissures avec le temps.<\/p>\n

Application<\/h2>
<\/div><\/div>[vc_column_text]<\/p>\n
Tecwool\u00ae<\/sup> 825<\/strong> s\u2019applique par machine pneumatique conform\u00e9ment aux sp\u00e9cifications techniques:<\/p>\n
Il n\u2019est pas n\u00e9cessaire de mettre aucun support pr\u00e9alable.<\/p>\n
La surface \u00e0 prot\u00e9ger doit \u00eatre exempt de poussi\u00e8re, huiles, r\u00e9sidus, particules mal adh\u00e9r\u00e9es, restes de peinture, etc.<\/p>\n
Il est souhaitable d\u2019arroser l\u00e9g\u00e8rement avec de l\u2019eau de le propre tuyau d\u2019application afin d\u2019\u00e9liminer tout salet\u00e9 dans le parement. Cela permettra d\u2019obtenir un \u00e9quilibre thermique entre le mortier et la surface appliqu\u00e9e.<\/p>\n
