Molecular Sieve 4A is used as a desiccant in an array of industrial applications. 4A molecular sieve means the molecules with the pore size of 4A0 or 4 angstroms are used for the adsorbing process. It simply signifies that molecules with the pores size larger than 4a cannot be used for adsorption. Generally, they are the sodium forms of the Type A structure.
Type 4a has reliable adsorption speed, higher resistance quality, and stronger adsorption, which are enough to enhance product life. Such type of molecular sieve is perfect to remove the moisture from liquids and gases. It is a universal dehydrating agent used in polar and non-polar media. This type of molecular sieve is the perfect desiccant for low inlet, humidity, with the temperature below 30-35% RH.
4A molecular sieves can be available in the form of beads, pellets and powder form.
Molecular sieve 4A is considered as one of the best desiccants for a variety of applications that includes:
Molecular sieve Type 4A can be regenerated and reused as per the needs. For regeneration process, it requires the removal of adsorbed moisture, water and other provisions at a hot temperature of 250 to 450 degrees. This temperature depends on when reached in the purge. To avoid any kind of accidental moisture adsorption, such molecular sieves are required to keep in an airtight container before using it. The adsorbed species include argon, SO2, CO2, carbon monoxide, C2H4, C3H6, C2H4, CH3CN2, CS2, CH3Br.
Molecular sieve powder has the ability to remove water & moisture, to eliminate bubbles, to increase the consistency & strength when mixed in paint, resin and other adhesives. It works as a desiccant in an insulating glass rubber spacer. It is advisable not to unpack the products or goods to avoid exposure in the air before their use. Always remember to keep such products at a dry place.
