Introduction
Ce document décrit les étapes nécessaires (à exécuter dans l'ordre) pour faire un traitement thermique sous azote à l'aide du four BlueM.
L'opérateur pourra choisir entre 2 programmes déjà enregistrés.
Matériaux
Outils
Étape 1 - Vérification disjoncteur / Branchement du Four
Vérifier que le disjoncteur du coffret électrique correspondant au four BlueM est bien enclenché
Vérifier que la prise triphasée du four est bien branchée
Étape 2 - Arrivée d'Azote
Vérifier que les 3 vannes de l'arrivée d'azote sont ouvertes
Vérifier que la pression lue sur le mano-détendeur est bien comprise entre 2,7 et3,5bars (idéalement fixée à 3bars) (manque photo)
Étape 3 - Aspiration de la salle blanche
Mettre en route l'extracteur de la salle blanche
Étape 4 - Contrôle de la différence de pression dans la Salle Blanche
Mettre en route la ventilation de la salle blanche (1)
Régler (2) la valeur de la différence de pression à 40Pa (3)
Étape 5 - Mettre les EPI
Avant de rentrer dans la salle blanche, mettre OBLIGATOIREMENT les EPI
- Blouse
- Gants
- Sur-chausses
Étape 6 - Ouverture du Four et chargement des échantillons
Vérifier la propreté à l’intérieur du four et sinon, nettoyer avec une chiffonnette salle blanche imbibée d'éthanol (Four froid).
Charger les échantillons dans le four et refermer. les deux portes
Étape 7 - Avant d'allumer le four
Vérifier que les 2 débitmètres du four sont bien fermés
Vérifier que la vanne de l'exhaust est ouverte (=en position horizontale)
Étape 8 - Mettre en route le four
Mettre le sectionneur sur ON (1)
Appuyer sur POWER CHAMBER (2) --> une alarme sonne pendant 5s
Étape 9 - Selection et lancement du programme
Sur le panneau d'affichage :
1/ Appuyer sur le bouton "LOCAL" ( un voyant vert se situe sous "local")
2/ Appuyer 2s sur Prg1 ou Prg2 selon le programme choisi (le voyant se met sous Prg1 ou Prg2). Le cycle démarre automatiquement
RQ : Le cycle commence par une purge de 30min à Tamb
Débit Throat flow --> 30scfh
Débit Chamber flow --> 100scfh
Quand la purge est terminée, régler les débitmètres selon le programme choisi
Étape 10 - Arret du four
Quand le cycle est terminé :
- Mettre les EPI
- Fermer les débitmètres
- Sortir les échantillons
- Fermer les portes du four
- Mettre le sectionneur sur OFF
Étape 11 - Cahier de laboratoire et Fiche "Program Setting Tables"
Remplir le cahier de laboratoire
- nom
- groupe
- date
- type d'échantillons
- programme
- durée d'utilisation
- remarque spécifique
Compléter la fiche "Programm Setting Tables" et la ranger dans le classeur
