Good Absorption 3a Molecular Sieve Desiccant Using Oil Industry Drying
Product Description
3A Molecular Sieve, has an effective pore opening of about 3 angstroms(0.3nm).
This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers.
It has the advantages of faster adsorption speed, more regeneration times, higher crushing strength, stronger anti-pollution ability, greater utilization efficiency and longer service life.
Chemical Molecular Formula : 0.4K2O·0.6Na2O·Al2O3·2SiO2··4.5H2O. (SiO2 : Al2O3 ≈2).
