Mots-cl\u00e9s : Plaque de surface en granit, propri\u00e9t\u00e9s des mat\u00e9riaux, pr\u00e9cision m\u00e9trologique, stabilit\u00e9 dimensionnelle
Les plaques de surface en granit sont r\u00e9put\u00e9es en m\u00e9trologie pour leurs propri\u00e9t\u00e9s physiques et m\u00e9caniques exceptionnelles. Leurs principales caract\u00e9ristiques sont les suivantes<\/p>\n\n\n\n

    \n
  1. Duret\u00e9 \u00e9lev\u00e9e et structure uniforme : Avec une duret\u00e9 Shore sup\u00e9rieure \u00e0 70Hs et une distribution min\u00e9rale uniforme, les plaques de granit r\u00e9sistent aux d\u00e9formations de surface sous de lourdes charges.<\/li>\n\n\n\n
  2. Stabilit\u00e9 thermique : Un coefficient de dilatation lin\u00e9aire de 4,61\u00d710-\u2076\/\u00b0C garantit une distorsion thermique minimale pendant l'utilisation, ce qui est essentiel pour les environnements \u00e0 temp\u00e9rature contr\u00f4l\u00e9e.<\/li>\n\n\n\n
  3. Inertie chimique : R\u00e9sistant aux acides, aux alcalis et aux solvants organiques, ils conviennent aux applications industrielles difficiles.<\/li>\n\n\n\n
  4. Fabrication de pr\u00e9cision : Les plaques modernes pr\u00e9sentent des \u00e9carts de plan\u00e9it\u00e9 de \u00b13\u03bcm sur de grandes surfaces (par exemple, 1000\u00d71000 mm), conform\u00e9ment aux normes ISO 8512-2 et AS 1004.2.<\/li>\n<\/ol>\n\n\n\n

    Une analyse comparative avec des plaques en fonte r\u00e9v\u00e8le la sup\u00e9riorit\u00e9 du granit en termes de stabilit\u00e9 dimensionnelle \u00e0 long terme et de r\u00e9sistance \u00e0 la corrosion. Des innovations r\u00e9centes, telles que les composites renforc\u00e9s par des nanoparticules, am\u00e9liorent encore la r\u00e9sistance \u00e0 l'usure sans compromettre l'homog\u00e9n\u00e9it\u00e9.<\/p>\n\n\n\n
