Le mat\u00e9riel de r\u00e9paration comprend : Perfectionnement du rev\u00eatement BN<\/strong>, Rev\u00eatement des moules \u00e0 lingots<\/strong>, Mortier r\u00e9fractaire<\/strong>. Il s'agit de mat\u00e9riaux de r\u00e9paration essentiels dans la fonderie d'alliages d'aluminium. Les mat\u00e9riaux de ragr\u00e9age prolongent la dur\u00e9e de vie de divers produits r\u00e9fractaires ; ils permettent d'emp\u00eacher l'adh\u00e9rence du m\u00e9tal \u00e0 la surface et de prot\u00e9ger le mat\u00e9riau de base contre l'attaque du m\u00e9tal en fusion. Le processus de corrosion induit par le m\u00e9tal en fusion \u00e9limine progressivement ce rev\u00eatement protecteur, rendant n\u00e9cessaire une nouvelle application. En r\u00e8gle g\u00e9n\u00e9rale, plus le rev\u00eatement est imperm\u00e9able au m\u00e9tal en fusion, meilleure est la protection r\u00e9fractaire et plus longue est la dur\u00e9e de vie du rev\u00eatement, bien que le syst\u00e8me de liant et d\u2019autres variables entrent \u00e9galement en ligne de compte.<\/p>\n

Perfectionnement du rev\u00eatement BN<\/strong><\/p>\n

\"Rev\u00eatement<\/p>\n

Les rev\u00eatements en nitrure de bore (BN) sont non mouillants vis-\u00e0-vis de l'aluminium fondu et sont devenus les rev\u00eatements les plus fiables et les plus utilis\u00e9s pour prot\u00e9ger efficacement les substrats en c\u00e9ramique et en acier. Perfectionnement du rev\u00eatement BN<\/strong><\/a>Il s'applique par pulv\u00e9risation ou au pinceau sur la surface des goulottes, des plaques de buse et des mat\u00e9riaux fonctionnels de moulage \u00ab hot-top \u00bb en contact avec l'aluminium en fusion. Il s'agit du principal mat\u00e9riau de ragr\u00e9age utilis\u00e9 dans l'industrie de la coul\u00e9e d'alliages d'aluminium. Apr\u00e8s ouverture, diluez-le avec de l'eau distill\u00e9e (eau\/rev\u00eatement = 3-6\/1), puis m\u00e9langez uniform\u00e9ment et appliquez le rev\u00eatement BN au pistolet ou au pinceau ; nettoyez la surface jusqu'\u00e0 ce qu'elle soit s\u00e8che.<\/p>\n

Rev\u00eatement des moules \u00e0 lingots<\/strong><\/p>\n

\"Rev\u00eatement<\/p>\n

Rev\u00eatement des lingoti\u00e8res<\/strong><\/a> est l'aspect gras ; vaporisez-le sur les moules en fonte destin\u00e9s \u00e0 la coul\u00e9e d'aluminium et d'alliages d'aluminium afin de leur conf\u00e9rer un aspect lisse et une protection contre l'oxydation. Vaporisez ou appliquez au pinceau apr\u00e8s avoir m\u00e9lang\u00e9 uniform\u00e9ment le produit.<\/p>\n

Mortier r\u00e9fractaire<\/strong><\/p>\n

\"Bou\u00e9e<\/p>\n

Bouillie isolante <\/strong>est \u00e9galement appel\u00e9 r\u00e9fractaire<\/strong> mortier<\/strong><\/a>. Il convient \u00e0 la fabrication et \u00e0 la r\u00e9paration de goulottes, de plaques de distribution, de cuves de filtration, de caissons de d\u00e9gazage et de rev\u00eatements de four ; il pr\u00e9sente les avantages d'une bonne adh\u00e9rence, d'une int\u00e9gration parfaite avec la partie r\u00e9par\u00e9e et d'une grande facilit\u00e9 d'utilisation.<\/p>\n
