Abstract

L'invention concerne un corps en nid d'abeilles en tant qu'élément de structure, présentant par rapport aux éléments de structure courants une moindre tendance à la rupture, une résistance élevée aux produits chimiques, une meilleure résistance à la corrosion, et une durée de vie plus longue. Le corps en nid d'abeilles comprend une première et une seconde face frontale agencées parallèlement l'une à l'autre, le corps en nid d'abeilles présente une structure en nid d'abeilles munie d'une pluralité de canaux agencés parallèlement les uns aux autres et adjacents les uns aux autres par des parois de canal, et le corps en nid d'abeilles est fabriqué dans une première matière plastique à base d'un matériau polymère polytétrafluoroéthylène (PTFE). Le corps en nid d'abeilles est en particulier destiné à être utilisé dans des systèmes de post-combustion, des systèmes de finition, dans des procédés permettant de faire fonctionner lesdits systèmes, et dans des procédés de concentration de substances contenues dans des gaz. Le corps en nid d'abeilles est par ailleurs en particulier destiné à être utilisé en tant que corps de support pour un milieu réactionnel biologique, pour la préparation de surfaces de sédimentation, dans des procédés permettant de faire fonctionner un système d'épuration biologique de l'eau et dans des procédé de séparation de substances sédimentables présentes dans des fluides.
