Résine chélatante de styrène macroporeuse CH520
La résine chélatante macroporeuse au styrène CH520 est un arbre échangeur de cations doté d'un groupe fonctionnel phosphoramidite. Cette résine chélate tous les ions métalliques divalents, en particulier les métaux alcalino-terreux, avec une sélectivité particulière. La CH520 est une résine idéale pour l'adoucissement de l'eau salée. Elle peut être utilisée pour éliminer les cations métalliques divalents des eaux usées industrielles et autres eaux industrielles. La CH520 est principalement utilisée pour le raffinage des saumures secondaires lors de la fabrication de soude caustique par membrane ionique. Elle peut réduire les ions calcium et magnésium dans les saumures secondaires à 20 ppb, et sa capacité d'échange de résine est supérieure à celle des résines aminoacides similaires utilisées à l'étranger. De plus, la D418 peut également être utilisée pour la récupération des métaux lourds dans les eaux usées de galvanoplastie.

Précautions
La résine doit être conservée à l'état humide. La température idéale est supérieure à 0 °C. En cas de non-utilisation prolongée, il est conseillé de la conserver dans un endroit fermé ou d'ajouter de l'eau salée à 5 % ou plus. Un antigel est recommandé pendant le transport. Ne pas poser d'objets lourds sur la résine afin de ne pas la heurter.
Le traitement nécessite généralement un circuit d'écoulement alcalin-eau-acide-eau. Trois cycles sont nécessaires avant d'atteindre le canal d'ions final.
Il faut tenir compte des différents taux d'expansion de transformation pour réserver suffisamment d'espace pour éviter le débordement de résine et garantir la hauteur de niveau de liquide appropriée ; le rapport de diamètre de la colonne doit être dans une plage raisonnable et éviter le courant de polarisation ; utiliser une colonne remplie d'eau ou un rinçage à contre-courant pour éliminer les bulles à l'intérieur de la couche de résine.
Avant que le liquide ne pénètre dans la colonne de résine, des étapes telles que la floculation, la filtration ou la filtration sur sable doivent être effectuées afin d'éviter que les pores de la résine ne soient obstrués par des solides en suspension.
La résine à l'intérieur de la colonne qui n'a pas été utilisée depuis longtemps doit être stockée à l'extérieur de la colonne après lavage, ou ajout d'eau salée dans le milieu résistant au sel tout en gardant le niveau de liquide non déshydraté avec un lavage à contre-courant habituel pour détacher la résine en cas d'agglomération.
