4A molecular sieve

4A molecular sieve
Product name:4A molecular sieve
Item:4A molecular sieve
Details:

 

BETE Molecular Sieve Feature:
1. Efficient desiccant
2. Consistent high adsorption speed
3. High contamination resistance
4. Strong crushing strength
5. Increasing cyclic times which provide an extended product life
 
4A molecular sieve
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. 4A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials. The sequence rate of adsorption is argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.
 
Item No.: (BT-MS3A-0.8/1, BT-MS3A-2/3BT-MS3A-3/5, BT-MS3A-4/6)
Chemical formula: Na2O·Al2O3·2SiO2·9/2H2O
SiO2:Al2O3 ≈ 2
Pore size
CAS: 70955-01-0
 
Application:
It is one of the most reliable desiccants for a variety of applications e.g.
  •         Refrigerant Drying
  •         Moisture removal in PU Plastic or Paint
  •         Natural Gas Drying
  •         Drying Cracked Gas
  •         Static drying of insulating glass units, whether air filled or gas-filled
  •         Dehydration of highly polar compounds, such as methanol and ethanol
  •         Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadiene)

Packing:
Plastic bag: 30kg / bag
Stainless steel drum: 135-150kg/drum
 
Storage:
Keep 4A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption, reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
 
Regeneration:
4A Molecular Sieve regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 4A Molecular Sieve heat to a temperature of 150-320 for 3-4 hours, and then pump in cool air for 2-3 hours.
