Uniform Pore Size Adsorbent 3A Molecular Sieve Desiccant For Adsorbing 1 2 3 Angstroms
Product Description of 3A Molecular Sieve Desiccant
Selective Adsorption According to Different Molecular Sizes and Shapes - Molecular Sieve Effect
The molecular sieve crystal has a honeycomb structure, the crystal cavities and channels in the crystal communicate with each other, and the pore size is uniform and fixed (the diameter of the molecular sieve cavity is generally between 6-15 angstroms), which is comparable to the size of the usual molecules, and only those diameters are compared. Only small molecules can be adsorbed by molecular sieves through the zeolite pores, while molecules with large configurations cannot be adsorbed by molecular sieves because they cannot enter the zeolite pores.
Silica gel, activated alumina and activated carbon do not have uniform pore size, and the pore size distribution range is very wide, so they have no screening performance.
a) Molecular sieves have reversible adsorption and desorption of water or various gas and liquid compounds.
b) The metal cations are readily exchangeable.
c) The cavities and channels within the molecular sieve form a very high internal surface area. Its inner surface can be 10,000-100,000 times higher than the outer surface area of the molecular sieve particles
