4A Molecular Sieve
Description:
4A molecular sieve is a kind of alkali metal alumino-silicate, in the sodium form of the Type A crystal structure.It could absorb the molecules which critical diameter is not more than 4 angstroms. The selective adsorption
performance of water is higher than any other molecules. It is one of the most used molecular sieve varieties in industry.
Chemical Molecular Formula:
Na2O·Al2O3·2SiO2·4.5H2O. (SiO2 : Al2O3 ≈2).
