Product Description

4a Molecular Sieve Desiccant Used for Adsorbing KNO3 and NH4NO3


Product Description


4A molecular sieve has a pore size of 4A or 4 angstrom. Any molecule larger than 4A will not be able to be adsorbed. 4 Angstroms are the sodium forms of the Type A crystal structure. The sequence rate of adsorption is argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.

It is professional for compressed air .
