Molecular sieve 4A

adsorb gas and liquid such as water ,natural gas; the high water adsorption properties; used widely in industry

1. Performance characteristics:

4A molecular sieve's aperture is 4A,it adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, and does not adsorb any molecular larger than   4A(including propane), the choice to water adsorption properties is higher than any other molecular. It is one of the largest varieties of molecular sieve in industry use.

 

2. Molecular formula: Na2O· Al2O3 ·2.0SiO2 ·4.5H2O

4.Specific applications: * The depth of drying of air, natural gas, paraffin gas ,liquid cooling agent and so on, and liquid.                           * Preparation and purification of argon gas. * The static desiccation of drugs packaging, electronic components and perishable goods. * Dehydrating agent to paint, fuel. 5.Packaging: 30g/bag,aluminum foil bags of vacuum-packed

 

6.Notes: Before use molecular sieve should prevent pre-adsorbed water, organic gases or liquids.Otherwise,it should be renewable.

 

7.Products should produce  in accordance with HG/T2524-93 standard.
