Les plaques filtrantes en acier inoxydable fritt\u00e9 sont des \u00e9l\u00e9ments de filtration poreux en forme de plaque, obtenus par la consolidation de mati\u00e8res premi\u00e8res en acier inoxydable (sous forme de poudre ou de treillis m\u00e9tallique) au moyen d'un proc\u00e9d\u00e9 de frittage. En fonction des mati\u00e8res premi\u00e8res utilis\u00e9es, elles sont principalement class\u00e9es en deux grandes cat\u00e9gories : les plaques filtrantes en poudre d'acier inoxydable fritt\u00e9e et les plaques filtrantes en treillis m\u00e9tallique d'acier inoxydable fritt\u00e9. Les plaques filtrantes en poudre fritt\u00e9e sont produites \u00e0 partir de poudre d'acier inoxydable comme mati\u00e8re premi\u00e8re, qui est consolid\u00e9e par frittage \u00e0 haute temp\u00e9rature ; \u00e0 l'inverse, les plaques filtrantes poreuses en treillis m\u00e9tallique fritt\u00e9 sont fabriqu\u00e9es en empilant plusieurs couches de treillis en acier inoxydable tiss\u00e9 et en les frittant dans des conditions de haute pression et de haute temp\u00e9rature, les mailles de chaque couche \u00e9tant d\u00e9cal\u00e9es afin de cr\u00e9er une structure \u00e0 gradient de taille de pores.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\u00c9tant donn\u00e9 que la mati\u00e8re premi\u00e8re des plaques filtrantes en treillis fritt\u00e9 poreux est le treillis m\u00e9tallique tiss\u00e9, elles offrent la m\u00eame plage de pr\u00e9cision de filtration que le treillis lui-m\u00eame, pouvant atteindre 1 micron au maximum. En revanche, la pr\u00e9cision des plaques filtrantes fritt\u00e9es \u00e0 partir de poudre n'est pas limit\u00e9e par les contraintes du tissage du treillis m\u00e9tallique, ce qui permet d'atteindre une pr\u00e9cision de filtration allant jusqu'\u00e0 0,45 micron. Par rapport au treillis tiss\u00e9, les plaques filtrantes en acier inoxydable fritt\u00e9 offrent des avantages significatifs en termes d'int\u00e9grit\u00e9 structurelle et d'uniformit\u00e9 (la plaque fritt\u00e9e formant une unit\u00e9 monolithique dont la structure poreuse ne subit aucune d\u00e9formation), de r\u00e9sistance m\u00e9canique et de performances dans des conditions de fonctionnement extr\u00eames (plus pr\u00e9cis\u00e9ment, la r\u00e9sistance \u00e0 la pression des plaques filtrantes fritt\u00e9es est nettement sup\u00e9rieure \u00e0 celle des mailles m\u00e9talliques en acier inoxydable non fritt\u00e9es).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Gr\u00e2ce \u00e0 leur r\u00e9sistance aux temp\u00e9ratures \u00e9lev\u00e9es, aux pressions \u00e9lev\u00e9es et \u00e0 la corrosion, les plaques filtrantes en acier inoxydable fritt\u00e9 sont largement utilis\u00e9es dans les secteurs suivants :
Industrie p\u00e9trochimique : utilis\u00e9 dans les unit\u00e9s de craquage catalytique pour la distribution de gaz \u00e0 haute temp\u00e9rature et la filtration par lavage \u00e0 contre-courant sous haute pression ;
Ils jouent un r\u00f4le essentiel dans des processus tels que la transformation des polym\u00e8res \u00e0 l'\u00e9tat fondu, la r\u00e9cup\u00e9ration des catalyseurs et la purification des solvants.
Industries agroalimentaire et pharmaceutique : utilis\u00e9es pour la filtration de pr\u00e9cision de produits alimentaires liquides \u2014 notamment les jus de fruits, les sirops et les huiles alimentaires \u2014 afin de garantir la puret\u00e9 des produits ; dans la fabrication pharmaceutique, elles servent \u00e0 la filtration st\u00e9rile des bouillons de fermentation et \u00e0 la filtration fine des solutions injectables.
Traitement de l'eau et protection de l'environnement : utilis\u00e9 dans le cadre du traitement des eaux us\u00e9es industrielles et du pr\u00e9traitement pour le dessalement de l'eau de mer.
\u00c9nergie et secteurs \u00e9mergents : Utilis\u00e9 pour la filtration de pr\u00e9cision des \u00e9lectrolytes dans la fabrication de batteries lithium-ion ; pour la purification des gaz dans les piles \u00e0 combustible \u00e0 hydrog\u00e8ne ; et dans le secteur a\u00e9rospatial pour la purification des fluides hydrauliques a\u00e9ronautiques et la filtration du carburant.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[1],"tags":[],"table_tags":[],"class_list":["post-29684","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/posts\/29684","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/comments?post=29684"}],"version-history":[{"count":4,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/posts\/29684\/revisions"}],"predecessor-version":[{"id":29689,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/posts\/29684\/revisions\/29689"}],"wp:attachment":[{"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/media?parent=29684"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/categories?post=29684"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/tags?post=29684"},{"taxonomy":"table_tags","embeddable":true,"href":"https:\/\/www.liandafiltration.com\/fr\/wp-json\/wp\/v2\/table_tags?post=29684"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
