Abstract

L'invention concerne une matière échangeuse d'ions hétérogène qui comprend une résine échangeuse d'ions incorporée dans un agglomérant. Ce dernier renferme une matière sélectionnée dans le groupe constitué par (i) un polyéthylène linéaire à basse densité catalysé au métallocène, (ii) un polyéthylène à très basse densité ou un polyéthylène à ultra basse densité traité au moyen de catalyseurs Ziegler-Natta ou des catalyseurs métallocène, (iii) une oléfine élastomère thermoplastique comprenant une phase continue polypropylène comportant un monomère éthylène-propylène-diène ou une phase caoutchouteuse d'un caoutchouc éthylène-propylène dispersée dans la phase continue polypropylène, et (iv) un vulcanisat thermoplastique comprenant une phase continue polypropylène comportant un monomère éthylène-propylène-diène, un caoutchouc éthylène-propylène, un caoutchouc nitrile-butadiène, un caoutchouc naturel, une phase caoutchouteuse éthylène-acétate de vinyle dispersée dans la phase continue polypropylène, un copolymère de fluorure de vinylidène et d'hexafluoropropylène, ou un copolymère de fluorure de vinylidène et d'hexafluoropropylène et de tétrafluoroéthylène. La membrane échangeuse d'ions peut être fabriquée au moyen de techniques d'extrusion avancées, comprenant l'alimentation informatisée de la matière, le réglage automatique et informatisé de l'épaisseur de la filière à segments de lèvres réglables indépendamment et à détection par jauge nucléaire à contrôle à rétroaction. La membrane peut également être fabriquée par moulage par injection.
