4A molecular sieve is an A-type alkali metal aluminosilicate crystal with a pore size of 4A. Its selective adsorption performance for water is higher than that of any other molecules, and it can also adsorb methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, etc. It does not adsorb molecules larger than 4A in diameter. It is widely used in the drying of gases and liquids, and can also be used in the refining and purification of certain gases or liquids, such as the purification of argon.
Xintao 4A molecular sieve has uniform pore size distribution, excellent adsorption performance and good oil adhesion, and has a certain buffer alkalinity effect, non-toxic, and has no adverse effect on ecology. In environments with high temperature or very low humidity, the water adsorption capacity far exceeds 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.
4) Used as a dehydrating agent in paints, fuels and coatings.
5) Dehydration of electrolyte solvent in lithium battery industry
