DESCRIPTION DU PRODUIT ZGC258<\/span><\/span><\/span><\/span><\/strong><\/p>\n

La ZGC258 est une r\u00e9sine \u00e9changeuse de cations macroporeuse et faiblement acide \u00e0 base d’acrylique contenant des groupes carboxyles. Elle peut \u00eatre utilis\u00e9e pour l’adoucissement, la d\u00e9shydratation, la d\u00e9min\u00e9ralisation et le traitement chimique. Elle est id\u00e9ale pour l’adoucissement de l’eau \u00e0 teneur \u00e9lev\u00e9e en solides dissous (TDS) et pour des applications sp\u00e9cifiques telles que la purification de solutions aqueuses organiques et l’\u00e9limination s\u00e9lective des ions de m\u00e9taux lourds. Elle peut \u00e9galement \u00eatre utilis\u00e9e pour la s\u00e9paration et la purification de substances biochimiques et pharmaceutiques.<\/span><\/span><\/span><\/span><\/p>\n

La r\u00e9sine ZGC258 pr\u00e9sente une grande capacit\u00e9 de traitement des cations divalents et une efficacit\u00e9 de r\u00e9g\u00e9n\u00e9ration extr\u00eamement \u00e9lev\u00e9e. Elle est disponible sous forme hydrog\u00e8ne (H) ou sodium (Na) pour des applications sp\u00e9cifiques. La s\u00e9rie ZGC258 comprend trois produits\u00a0: la ZGC258 pour un usage g\u00e9n\u00e9ral\u00a0; la ZGC258FC pour les syst\u00e8mes bicouches et \u00e0 lit flottant\u00a0; et la ZGC258SC pour les syst\u00e8mes bicouches. La ZGC258DQ est trait\u00e9e en profondeur pour une utilisation dans l’eau.<\/span><\/span><\/span><\/span><\/p>\n

\u25cf PARTICULES FINES, FAIBLE R\u00c9SISTANCE HYDRAULIQUE<\/span><\/span><\/span><\/span><\/p>\n

95 % des granul\u00e9s se situent dans la plage de taille sp\u00e9cifi\u00e9e, ce qui entra\u00eene une perte de pression plus faible.<\/span><\/span><\/span><\/span><\/p>\n

\u25cf HAUTE STABILIT\u00c9 CHIMIQUE ET PHYSIQUE<\/span><\/span><\/span><\/span><\/p>\n

Une sph\u00e9ricit\u00e9 de 93 %, associ\u00e9e \u00e0 un faible gonflement, une structure macroporeuse, une r\u00e9sistance \u00e9lev\u00e9e \u00e0 la traction et une granulom\u00e9trie uniforme, offrent une r\u00e9sistance accrue aux contraintes m\u00e9caniques, thermiques ou osmotiques.<\/span><\/span><\/span><\/span><\/p>\n

Le ZGC258 sous forme d’hydrog\u00e8ne peut \u00eatre utilis\u00e9 pour \u00e9liminer les cations bivalents associ\u00e9s \u00e0 l’alcalinit\u00e9 dans les syst\u00e8mes de d\u00e9min\u00e9ralisation multicouches. La r\u00e9sine acide faible peut \u00eatre r\u00e9g\u00e9n\u00e9r\u00e9e de mani\u00e8re \u00e9conomique gr\u00e2ce \u00e0 l’acide us\u00e9 de l’unit\u00e9 de cations secondaires.<\/span><\/span><\/span><\/span><\/p>\n

Le ZGC258 est utilis\u00e9 pour l’isolement de certains antibiotiques des milieux de fermentation dans lesquels ils sont produits, ainsi que pour leur purification finale. Il peut \u00e9galement \u00eatre utilis\u00e9 pour la purification d’acides amin\u00e9s et de divers compos\u00e9s biochimiques.<\/span><\/span><\/span><\/span><\/p>\n
