Product Description

4A Molecular Sieve

Production Description:
Molecular sieve 4A is a kind of alkali-metallic silicon-aluminum compounds ,it is the sodium form of the type a crystal structure. Molecular sieve 4A has an effective pore opening of 4 angstroms(0.4nm),4A molecular sieves can absorb the molecules which critical diameter is not more than 4 angstroms, 4A molecular sieves is sued in the dryness of gases and liquid, and absorb H2O,NH3,H2S,SO2,CO2,C2H5OH,C2H6,C2H4,C3H6 and so on,4A molecular sieve is also used for dryness of impurity gas in oil,
Oil & natural gas and dehydration of ethanol, if it lost effectiveness,4A zeolite can be regenerated to reuse

Application:
Deep drying of gases and liquids, such as air,natural gas,refrigerants,solvents etc.
Drying of saturated hydrocarbons
Refining and purification of argon gas.
Static dehydration of electronic element ,pharmaceutical and unstable materials

Material:
Type:4A,Pore diameter:4 angstroms;chemical Form:Na2O~AL2O3~2SiO2~9/2H2O(SiO2/AL2O3=2)
