O di\u00e2metro das part\u00edculas e o m\u00e9todo de utiliza\u00e7\u00e3o da peneira molecular 4A<\/h1>\n

<\/p>\n

\n

1. O di\u00e2metro das part\u00edculas do crivo molecular 4A<\/h2>\n

<\/p>\n

As peneiras moleculares 4A s\u00e3o divididas em tiras e formas esf\u00e9ricas, e os di\u00e2metros das diferentes formas tamb\u00e9m s\u00e3o diferentes, mas o tamanho das mol\u00e9culas que podem ser adsorvidas permanece inalterado. A forma granular \u00e9 esf\u00e9rica, com um di\u00e2metro de 1,7 a 2,5 mm e 3,0 a 5,0 mm.<\/p>\n

<\/p>\n

2. Como utilizar o crivo molecular 4A<\/h2>\n

<\/p>\n

O peneiro molecular 4A \u00e9 um tipo de peneiro molecular A. O cati\u00e3o \u00e9 o i\u00e3o s\u00f3dio. O di\u00e2metro do poro \u00e9 de 4nm. Adsorve principalmente mol\u00e9culas com um di\u00e2metro de peneira molecular inferior a 4A, incluindo \u00e1gua, carbono, \u00e1lcoois, olefinas, etc., e as subst\u00e2ncias que podem ser absorvidas pela peneira molecular 3A podem ser todas adsorvidas pela peneira molecular 4A. Como um aluminossilicato de metal alcalino, \u00e9 preferido por muitos clientes em termos de secagem de gases e l\u00edquidos. Tamb\u00e9m pode ser utilizado para a refina\u00e7\u00e3o e purifica\u00e7\u00e3o de gases ou l\u00edquidos, como a extra\u00e7\u00e3o de \u00e1rgon.<\/p>\n

<\/p>\n

3. A diferen\u00e7a entre o crivo molecular 3A, o crivo molecular 4A e o crivo molecular 5A<\/h2>\n

<\/p>\n

A f\u00f3rmula qu\u00edmica de : 2\/3K2O13\u00b7Na22O\u00b7Al2O3\u00b72SiO2.\u00b74.5H2O<\/p>\n

A f\u00f3rmula qu\u00edmica da peneira molecular 4A: Na2O\u00b7Al2O3\u00b72SiO2\u00b74.5H2O<\/p>\n

A f\u00f3rmula qu\u00edmica da peneira molecular 5A: 3\/4CaO1\/4Na2OAl2O3\u00b72SiO2\u00b74.5H2O<\/p>\n

<\/p>\n

O princ\u00edpio de funcionamento das peneiras moleculares est\u00e1 principalmente relacionado com as dimens\u00f5es dos poros das peneiras moleculares, que s\u00e3o 0,3 nm\/0,4 nm\/0,5 nm, respetivamente. Podem adsorver mol\u00e9culas de g\u00e1s cujo di\u00e2metro molecular \u00e9 menor do que o tamanho dos poros. Quanto maior for o tamanho dos poros, maior ser\u00e1 a capacidade de adsor\u00e7\u00e3o. O tamanho dos poros \u00e9 diferente, e as coisas separadas pela peneira tamb\u00e9m s\u00e3o diferentes. Em termos simples, a peneira molecular 3A s\u00f3 pode adsorver mol\u00e9culas inferiores a 0,3 nm; em termos de peneira molecular 4A, as mol\u00e9culas adsorvidas tamb\u00e9m devem ser inferiores a 0,4 nm; o mesmo se aplica \u00e0 peneira molecular 5A. Quando utilizado como dessecante, um crivo molecular pode absorver a \u00e1gua at\u00e9 22% do seu pr\u00f3prio peso.<\/p>\n<\/p><\/div>\n
