Le proc\u00e9d\u00e9 d\u2019attaque permet le collage du PTFE<\/h1><\/div>

Le PTFE est naturellement non adh\u00e9sif. Pour coller du PTFE sur une autre surface, m\u00e9tal, plastique ou caoutchouc, l\u2019attaque est le seul moyen. Le proc\u00e9d\u00e9 d\u2019attaque consiste \u00e0 modifier la surface du PTFE pour que les adh\u00e9sifs adh\u00e8rent \u00e0 la surface.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

L\u2019attaque consiste \u00e0 traiter la surface des pi\u00e8ces en PTFE pour modifier l\u00e9g\u00e8rement sa structure chimique sur une fine couche de mat\u00e9riau. Le PTFE \u00e9tant l’un des mat\u00e9riaux les plus r\u00e9sistants \u00e0 la corrosion, seules quelques solutions existent. Ceci explique aussi pourquoi la modification du PTFE ne s’appliquera que sur une couche mince et ne d\u00e9t\u00e9riorera pas son \u00e9tanch\u00e9it\u00e9 ou sa r\u00e9sistance chimique sur le reste de la pi\u00e8ce en PTFE.<\/p>\n

3P utilise le proc\u00e9d\u00e9 d\u2019attaque \u00e0 l’ammoniaque de sodium, qui est la solution la plus efficace et la plus durable. L\u2019attaque est utilis\u00e9es sur toutes sortes de pi\u00e8ces : films, rubans adh\u00e9sifs PTFE, mais aussi sur des pi\u00e8ces d\u00e9coup\u00e9es ou usin\u00e9es.<\/p>\n

Les parties attaqu\u00e9es sont facilement reconnaissables car elles pr\u00e9sentent une coloration brune typique.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>

Les pi\u00e8ces semi-finies ou finies sont fournies avec une surface attaqu\u00e9es ou peuvent \u00eatre fournies directement avec de l’adh\u00e9sif.<\/p>\n

Le silicone et l’acrylique sont les adh\u00e9sifs les plus utilis\u00e9s. D\u2019autres options existent. Dans tous les cas, l’adh\u00e9sif doit \u00eatre choisi pour sa compatibilit\u00e9 avec le mat\u00e9riau de surface et la temp\u00e9rature de service.<\/p>\n

L’adh\u00e9sif acrylique supporte une r\u00e9sistance plus \u00e9lev\u00e9e (20 N\/25 mm pour les films) et peut \u00eatre utilis\u00e9 de -55\u00b0C \u00e0 85\u00b0C.<\/p>\n

L\u2019adh\u00e9sif silicone supporte 7 N\/25 mm (pour les films) et peut \u00eatre utilis\u00e9 sur une plage de temp\u00e9rature plus large, de -85\u00b0C \u00e0 150\u00b0C.<\/p>\n

3P est l’un des principaux fournisseurs de films PTFE attaqu\u00e9s ou adh\u00e9siv\u00e9s pour l’industrie a\u00e9rospatiale. En cons\u00e9quence, les films peuvent \u00eatre fournis selon des exigences personnalis\u00e9es ou selon les exigences ASNA 3634 ou ABS 5766.<\/p>\n<\/div>\n

3P propose \u00e9galement la gamme 3P-FluoLiner\u00ae<\/a> de bandes PTFE attaqu\u00e9es. Ces bandes sont principalement utilis\u00e9es comme rev\u00eatement protecteur anticorrosion pour les r\u00e9servoirs de haute puret\u00e9, les conteneurs ISO, les cuves ou les colonnes. Nos produits sont utilis\u00e9s pour leur forte capacit\u00e9 d’adh\u00e9rence sur les substrats en acier, leur inertie chimique \u00e0 presque tous les liquides, une longue dur\u00e9e de vie, une plage de temp\u00e9rature \u00e9tendue et une bonne r\u00e9sistance \u00e0 la fissuration sous contrainte.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>

Comme de plus en plus d’entreprises industrielles demandent des gammes compl\u00e8tes de solutions, il est \u00e9galement possible d’externaliser le collage et l’assemblage.<\/p>\n

3P a r\u00e9cemment investi dans des \u00e9quipements pour coller le PTFE \u00e0 des surfaces m\u00e9talliques. Ce savoir-faire est compatible avec un contr\u00f4le drastique des impuret\u00e9s. Ce proc\u00e9d\u00e9 par cuisson garantit un collage durable du PTFE sur les pi\u00e8ces m\u00e9talliques.<\/p>\n<\/div>\n
