4A Molecular Sieve Activated Alumina

4A molecular sieve characteristics:

4A molecular sieve activated alumina refers to sodium A-type aluminosilicate. The pore size of the molecular sieve is 4A. It adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. The selective adsorption performance of water is higher than any other molecule, and it is one of the most widely used molecular sieve varieties in the industry. 4A molecular sieve activated alumina can also be used in the drying of saturated hydrocarbon materials and the drying of natural gas industries. The silicon to aluminum ratio is two.

4A molecular sieve uses

● Deep drying of air, natural gas, alkanes, refrigerants and other gases and liquids

● Preparation and purification of argon

● Static drying of pharmaceutical packaging, electronic components and perishable substances

● Used as dehydrating agent in paint, fuel and coating

● Matching with activated alumina balls is suitable for air separation post-processing equipment

4A molecular sieve packaging

● 25KG carton package, inner vacuum packaging

● 25KG paper drum packaging, inner vacuum packaging

● Packed in 50KG or 150KG iron drum, vacuum packed inside

4A molecular sieve activated alumina matters needing attention

4A molecular sieve activated alumina should be prevented from adsorbing water, organic gas or liquid before use, otherwise it should be regenerated. Molecular sieves are easy to absorb moisture and should not be directly exposed to the air. They should be stored in a dry place during storage. After adsorption for a period of time, regeneration treatment can be performed. The regeneration temperature is preferably below 350°C.
