Les 6 phases du cycle d’impr\u00e9gnation sous vide du bois<\/strong><\/h2>\n
\n

\"\"<\/p>\n

Phase 1: Vide initial<\/strong><\/p>\n

Une fois plac\u00e9e sur le chariot motoris\u00e9 de l’autoclave, la pile de bois est amen\u00e9e dans l’installation pour la mise en marche du cycle.
\nLa fermeture herm\u00e9tique de la porti\u00e8re permet \u00e0 la machine de commencer le traitement \u00e0 travers l’actionnement de la pompe de vide. Cette phase, tr\u00e8s importante pour la bonne r\u00e9ussite du cycle, lib\u00e8re les trach\u00e9ides du bois de l’air, en g\u00e9n\u00e9rant une “d\u00e9pression” qui permettra au bois “d’aspirer” dans son int\u00e9rieur la solution pr\u00e9servante. La p\u00e9riode de vide peut varier de 30 \u00e0 90 minutes selon les caract\u00e9ristiques du bois.<\/p>\n

\n

\"\"<\/p>\n

Phase 2: Remplissage<\/strong><\/p>\n

Une fois la premi\u00e8re phase finie, on utilise la d\u00e9pression pour transporter la solution de traitement du r\u00e9cipient inf\u00e9rieur vers l’autoclave sup\u00e9rieure.
\nLa phase de remplissage est r\u00e9gul\u00e9e par un senseur de niveau ad\u00e9quat qui envoie un signal de contr\u00f4le \u00e0 l’ordinateur de l’installation.<\/p>\n

\n

\"\"<\/p>\n

Phase 3 : Application de la pression<\/strong><\/p>\n

La troisi\u00e8me phase du traitement a le devoir important de “forcer” la solution \u00e0 l’int\u00e9rieur du bois.<\/p>\n

Le fonctionnement de la pompe \u00e0 pression peut changer de 30 \u00e0 180 minutes selon les caract\u00e9ristiques du mat\u00e9riel.
\nL’action combin\u00e9e avec le vide permettra aux principes actifs de se fixer en profondeur pour garantir une protection durable.<\/p>\n

\n

\"\"<\/p>\n

Phase 4: Evacuation de la solution<\/strong><\/p>\n

Une fois les phases de traitement proprement dites achev\u00e9es, la solution qui n’a pas \u00e9t\u00e9 absorb\u00e9e par le bois retourne dans le r\u00e9cipient au dessous \u00e0 travers une vanne d’\u00e9vacuation plac\u00e9e sur le fond de l’autoclave.
\nDes syst\u00e8mes automatiques ad\u00e9quats permettent d’\u00e9quilibrer le contenu en sels et de mettre \u00e0 nouveau au niveau optimal l’impr\u00e9gnant pour un nouveau cycle.
\nToute la solution qui n’a pas \u00e9t\u00e9 absorb\u00e9e est disponible pour une nouvelle utilisation sans aucun gaspillage.<\/p>\n

\n

\"\"<\/p>\n

Phase 5: Vide de r\u00e9cup\u00e9ration<\/strong><\/p>\n

Une action ult\u00e9rieure du vide d’une dur\u00e9e d’environ 20-40 minutes facilite la fixation des principes actifs dans le bois.
\nCette phase est importante pour faciliter le “suintement” du mat\u00e9riel trait\u00e9.<\/p>\n

\n

\"\"<\/p>\n

Phase 6: Fin du cycle<\/strong><\/p>\n

A la fin du cycle d’impr\u00e9gnation, l’autoclave est port\u00e9e de nouveau \u00e0 pression atmosph\u00e9rique et le bois est pr\u00eat pour les phases de travail suivantes.<\/p>\n

\n

Dur\u00e9e du processus<\/strong><\/p>\n

La dur\u00e9e du processus est variable et elle est li\u00e9e aux facteurs suivants:<\/p>\n

    \n
  • Caract\u00e9ristiques du bois;<\/li>\n
  • Epaisseur;<\/li>\n
  • Humidit\u00e9;<\/li>\n
  • Quantit\u00e9 et concentration des sels que l’on veut fournir.<\/li>\n<\/ul>\n
