Diam\u00e8tre des particules et m\u00e9thode d'utilisation du tamis mol\u00e9culaire 4A<\/h1>\n

<\/p>\n

1. Le diam\u00e8tre des particules du tamis mol\u00e9culaire 4A<\/h2>\n

<\/p>\n

Les tamis mol\u00e9culaires 4A sont divis\u00e9s en bandes et en formes sph\u00e9riques, et les diam\u00e8tres des diff\u00e9rentes formes sont \u00e9galement diff\u00e9rents, mais la taille des mol\u00e9cules qui peuvent \u00eatre adsorb\u00e9es reste inchang\u00e9e. La forme granulaire est sph\u00e9rique, avec un diam\u00e8tre de 1,7 \u00e0 2,5 mm et de 3,0 \u00e0 5,0 mm.<\/p>\n

<\/p>\n

2. Comment utiliser le tamis mol\u00e9culaire 4A<\/h2>\n

<\/p>\n

Le tamis mol\u00e9culaire 4A est un type de tamis mol\u00e9culaire A. Le cation est l'ion sodium. Le diam\u00e8tre des pores est de 4 nm. Il adsorbe principalement les mol\u00e9cules dont le diam\u00e8tre du tamis mol\u00e9culaire est inf\u00e9rieur \u00e0 4A, notamment l'eau, le carbone, les alcools, les ol\u00e9fines, etc., et les substances qui peuvent \u00eatre absorb\u00e9es par le tamis mol\u00e9culaire 3A peuvent toutes \u00eatre adsorb\u00e9es par le tamis mol\u00e9culaire 4A. En tant qu'aluminosilicate de m\u00e9tal alcalin, le tamis mol\u00e9culaire 4A est appr\u00e9ci\u00e9 par de nombreux clients pour le s\u00e9chage des gaz et des liquides. Il peut \u00e9galement \u00eatre utilis\u00e9 pour le raffinage et la purification des gaz ou des liquides, comme l'extraction de l'argon.<\/p>\n

3. Diff\u00e9rence entre le tamis mol\u00e9culaire 3A, le tamis mol\u00e9culaire 4A et le tamis mol\u00e9culaire 5A<\/h2>\n

<\/p>\n

La formule chimique de : 2\/3K2O13\u00b7Na22O\u00b7Al2O3\u00b72SiO2.\u00b74.5H2O<\/p>\n

La formule chimique du tamis mol\u00e9culaire 4A : Na2O\u00b7Al2O3\u00b72SiO2\u00b74.5H2O<\/p>\n

Formule chimique du tamis mol\u00e9culaire 5A : 3\/4CaO1\/4Na2OAl2O3\u00b72SiO2\u00b74.5H2O<\/p>\n

<\/p>\n

Le principe de fonctionnement des tamis mol\u00e9culaires est principalement li\u00e9 \u00e0 la taille des pores des tamis mol\u00e9culaires, qui sont respectivement de 0,3 nm\/0,4 nm\/0,5 nm. Ils peuvent adsorber des mol\u00e9cules de gaz dont le diam\u00e8tre mol\u00e9culaire est inf\u00e9rieur \u00e0 la taille des pores. Plus la taille des pores est importante, plus la capacit\u00e9 d'adsorption est \u00e9lev\u00e9e. La taille des pores est diff\u00e9rente, et les \u00e9l\u00e9ments s\u00e9par\u00e9s par le tamis sont \u00e9galement diff\u00e9rents. En termes simples, le tamis mol\u00e9culaire 3A ne peut adsorber que des mol\u00e9cules inf\u00e9rieures \u00e0 0,3 nm ; en ce qui concerne le tamis mol\u00e9culaire 4A, les mol\u00e9cules adsorb\u00e9es doivent \u00e9galement \u00eatre inf\u00e9rieures \u00e0 0,4 nm ; il en va de m\u00eame pour le tamis mol\u00e9culaire 5A. Lorsqu'il est utilis\u00e9 comme d\u00e9shydratant, un tamis mol\u00e9culaire peut absorber l'eau jusqu'\u00e0 22% de son propre poids.<\/p>\n<\/p><\/div>\n
