Molecular Sieve 3A |
The
pore size of 3A molecular sieve is 3 A0 . It
does not adsorb any molecular larger than 3 A0.
According to the industrial application specialties, we
endue our products with the characters of higher adsorption
speed, stronger crushing and anti-contaminative resistance,
more cyclic times and longer work-span. All these advantage
have made it come to be the most essential and necessary
desiccant in the fields of the deep drying, refinery, polymerization
for cracked gases, ethylene, propylene and any other non-acidic
gases or liquids in petroleum and chemical industrials.

Type
3A molecular sieves should be used to dry dehydration solvents
for electron microscopy. Most common solvents (acetone,
ethanol, and methanol, etc.) need to be anhydrous for electron
microscopy embedding work using epoxy resins, yet they have
a tendency to pick up atmospheric water when bottles are
opened. Molecular sieves are used to dehydrate the solvents
used in the final stages of dehydration and embedding.

3A
molecular sieve is mainly applied to absorb water molecular
in drying natural gas and oil gases, especially in drying
Catalystic Splitting Decomposition Oil gases and Alkene.
So it is usually used as fine drying agent in medicine,
food, glass industry and so on.
