Reversible 3A Molecular Sieve Desiccant For Adsorb Desorb Chemical Compound Substance
Reversible Adsorbent 3A Molecular Sieve Desiccant For Adsorb & Desorb Chemical Compound Substance
Product Description of 3A Molecular Sieve Desiccant
- Molecular sieves can reversibly adsorb and desorb water or various gas and liquid compounds.
- Metal cations are easily exchanged.
- The cavities and channels inside the molecular sieve form a very high internal surface area. Its inner surface can be 10000-100000 times higher than the outer surface area of molecular sieve particles
Selective Adsorption Based on Different Molecular Size and Shape - 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, only those diameters are compared. Only small molecules can be adsorbed by molecular sieves through zeolite pores, while molecules with large configurations cannot be adsorbed by molecular sieves because they cannot enter the zeolite pores.
However, silica gel, activated alumina and activated carbon have no uniform pore size, and the pore size distribution range is very wide, so they have no screening performance.
