Types et structures de tamis mol\u00e9culaires<\/h1>\n

<\/p>\n

\n

\u2160. Il existe deux types de tamis mol\u00e9culaires : la z\u00e9olithe naturelle et la z\u00e9olithe synth\u00e9tique.<\/h2>\n

<\/p>\n

1. La plupart des z\u00e9olithes naturelles sont form\u00e9es par la r\u00e9action de tufs volcaniques et de roches s\u00e9dimentaires tuffac\u00e9es dans des environnements marins ou lacustres. \u00c0 l'heure actuelle, plus de 1 000 types de min\u00e9raux z\u00e9olithiques ont \u00e9t\u00e9 d\u00e9couverts, dont 35 sont les plus importants. Les plus courants sont la clinoptilolite, la mord\u00e9nite, l'\u00e9rionite et la chabazite.<\/p>\n

<\/p>\n

2. Les ressources \u00e9tant limit\u00e9es, les gens utilisent par la suite des z\u00e9olithes synth\u00e9tiques en grandes quantit\u00e9s. Les tamis mol\u00e9culaires commerciaux utilisent souvent des pr\u00e9fixes pour classer les tamis mol\u00e9culaires ayant des structures cristallines diff\u00e9rentes, comme le type 3A, le type 4A et .<\/p>\n

\u2161. La structure du tamis mol\u00e9culaire<\/h2>\n

<\/p>\n

Une structure microporeuse ressemblant \u00e0 un tamis, form\u00e9e par l'enroulement tortueux de polym\u00e8res de prot\u00e9oglycanes, est appel\u00e9e tamis mol\u00e9culaire. Le tamis mol\u00e9culaire ne laisse passer que les substances plus petites que ses micropores et a un effet de barri\u00e8re sur les substances macromol\u00e9culaires et les bact\u00e9ries plus grandes que ses micropores. Ses pores ont un diam\u00e8tre uniforme et peuvent adsorber des mol\u00e9cules plus petites que leur diam\u00e8tre dans les cavit\u00e9s. Il peut donc s\u00e9parer des mol\u00e9cules ayant diff\u00e9rents degr\u00e9s d'accessibilit\u00e9, de saturation, de taille mol\u00e9culaire et de point d'\u00e9bullition, et a la fonction de \"tamiser\" les mol\u00e9cules.<\/p>\n<\/p><\/div>\n

At present, more than 1,000 kinds of zeolite minerals have been discovered, of which 35 are more important. The common ones are clinoptilolite, mordenite, erionite and chabazite. 2.
