Molecular Sieve type 4A (Angstrom) is an alkali aluminosilicate, obtained through synthesis of type A zeolite in sodicform. It is the sodium form of the Type A crystal structure. 4Amolecular sieve has an effective pore opening of about 4 angstroms(0.4nm). Galaxychem type 4A molecular sieve will adsorb mostmolecules with a kinetic diameter of less than 4 angstroms andexclude those larger.
4A is widely used to dry gas and liquid, such as cracked gas,natural gas, refrigent, liquid gas, naphtha, kerosene, diesel oiland transformer oil, etc. It can be also employed to extract,purify argon and desulphurization. It will adsorb, in sequence ofadsorption rate, argon, krypton, xenon, ammonia, carbon monoxide,C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbondioxide.
APPLICATION FIELD:
1. Deep drying of air, natural gas, alkane and refrigerant.
2. Generation and purification of argon.
3. Static dehydration of electronic element, pharmaceutical andunstable materials.
4. Desiccant of paint, PU Plastic, dope and fuel etc.
5. Also adsorb H2O, NH3, CO, CO2, SO2, H2S, CH3OH, C2H5OH,C2H4,
C2H2, C3H6, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide. etc.
TECHNIQUE SPECIFICATION:
1.6-2.5 sphere, 3-5mm sphere, 5-8mm sphere, and 1.6mm cylinder,3.2mm cylinder is available in stock.

STORAGE:
It should be stored at room temperature, in which the relativehumidity is not exceed 90%, and be not exposed in air, andprevented against water, acids and alkalies.
REGENERATION:
Molecular sieve can be regenerated for re-use by purging orevacuating at elevated temperatures. The degree of regeneration(adsorbed substances removal) is dependent on the temperature andhumidity of the purge gas. In practice, blowing the molecular sieveby dry purge gas at an inlet temperature of 200degreescentigrade-350 degrees centigrade and a pressure of 0.3 - 0.5 kgper square centimetre, heat the molecular sieve bed. As thetemperature in outlet reaches 150 - 180degrees centigrade, let thebed cool off.
