Molecular sieve 3A is an alkali metal aluminosilicate. Sometimes, it is also called molecular sieve 3A zeolite. Wholesale of molecular sieves.

Molecular sieve 3A is an alkali metal aluminosilicate. Sometimes, it is also called molecular sieve 3A zeolite.

Chemical formula: 2/3K2O·1/3Na2O·Al2O3·2SiO2·9/2H2O

Effective pore diameter: approximately 3 Å (1 Å = 0.1 nanometers);

The pore diameter of molecular sieve 3A is 3 Å. It is mainly used for adsorbing water and does not adsorb any molecules with a diameter larger than 3 Å. According to the application characteristics in the industry, the molecular sieve has the advantages of fast adsorption speed, a large number of regeneration cycles, high crushing resistance strength and strong anti-pollution ability. These features improve the utilization efficiency of the molecular sieve and extend its service life. It is an essential desiccant for the deep drying, refining and polymerization of gas and liquid phases in the petroleum and chemical industries.
