4A molecular sieve is a type A alkali metal salt crystal with a pore size of 4A. Its selective adsorption performance for water is higher than that of any other molecule. It can also adsorb methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, etc. Adsorbs molecules with a diameter larger than 4A. It is widely used for drying gases and liquids, and can also be used for refining and purifying certain gases or liquids, such as the production of argon.
CNM 4A molecular sieve has very uniform pore size distribution, very good adsorption performance and good oil adhesion, has a certain buffering alkalinity effect, is non-toxic, safe and reliable for the human body, and has no adverse impact on the ecology. In environments with high temperatures or very low humidity, the ability to absorb water is guaranteed to exceed that of other desiccants.
The main uses are:
1) Deep drying of gases and liquids such as air, natural gas, alkanes, and refrigerants.
2) Static drying of pharmaceutical packaging, electronic components and perishable objects.
3) Preparation and purification of argon gas.
4) Used as dehydrating agent in paints, fuels and coatings.
5) Dehydration of electrolytic solvents in the lithium point industry.
