Le xylom\u00e8tre<\/strong> est un instrument qui permet de mesurer la densit\u00e9 du bois. Il fonctionne gr\u00e2ce au principe d\u2019Archim\u00e8de : on plonge un morceau de bois dans l\u2019eau pour voir quel volume d\u2019eau il d\u00e9place. En comparant le poids du bois et la quantit\u00e9 d\u2019eau d\u00e9plac\u00e9e, on peut conna\u00eetre sa densit\u00e9 et, donc, savoir s\u2019il est bien sec ou s\u2019il contient encore beaucoup d\u2019humidit\u00e9.<\/p>\n\n\n\n

Examinons de plus pr\u00e8s son utilit\u00e9 pour les ouvriers que nous allons rencontrer au cours de ce ChallengeAZ.<\/p>\n\n\n\n

Le meunier<\/strong><\/p>\n\n\n\n

Dans le m\u00e9tier de meunier, le bois a longtemps \u00e9t\u00e9 essentiel. Le meunier avait besoin de bois sec pour faire fonctionner les moulins, chauffer l\u2019eau ou entretenir les engrenages en bois. Gr\u00e2ce au xylom\u00e8tre, il pouvait v\u00e9rifier si le bois achet\u00e9 \u00e9tait vraiment sec et s\u2019il contenait la bonne quantit\u00e9 de mati\u00e8re. Un bois trop humide br\u00fble mal et co\u00fbte plus cher, d\u2019o\u00f9 l\u2019importance de cette mesure.<\/p>\n\n\n\n

Le papetier<\/strong><\/p>\n\n\n\n

Le papetier, qui fabrique du papier \u00e0 partir de fibres de bois, utilise aussi le xylom\u00e8tre. Cet outil lui permet de choisir des b\u00fbches ou des copeaux de bois ayant une densit\u00e9 id\u00e9ale pour produire une p\u00e2te de qualit\u00e9. Un bois bien mesur\u00e9 donnera plus de fibres, et donc un papier plus solide. C\u2019est une \u00e9tape importante pour s\u2019assurer que la mati\u00e8re premi\u00e8re est adapt\u00e9e \u00e0 la fabrication.<\/p>\n\n\n\n

Ce papier de qualit\u00e9 peut ensuite \u00eatre transform\u00e9 en cartes postales. Pour qu\u2019une carte postale soit r\u00e9sistante au voyage, il faut un papier \u00e9pais et robuste. Gr\u00e2ce au xylom\u00e8tre, le papetier peut s\u00e9lectionner le meilleur bois pour produire une p\u00e2te qui donnera un papier ferme et durable, parfait pour imprimer de belles images ou \u00e9crire des messages qui traverseront le temps.<\/p>\n\n\n\n

Ainsi, m\u00eame si le xylom\u00e8tre est un outil discret, il joue un r\u00f4le essentiel dans la cha\u00eene qui va du bois brut jusqu\u2019\u00e0 la carte postale que l\u2019on envoie \u00e0 ses proches.<\/strong><\/p>\n\n\n\n
