Introduction of 4A Molecular Sieve Desiccant:

The characteristics and uses of 4a molecular sieve, 4a molecular sieve is a microporous cubic lattice of synthetic aluminum silicate. It is called a "molecular sieve" because it absorbs or repels molecules of different substances depending on the size of the pores in the crystal. Materials whose molecular diameter is smaller than the pore size of the molecular sieve can enter the molecular sieve and be adsorbed.

 

Ion exchange performance - water softening function: Each oxygen atom in the 4A molecular sieve framework is shared by two adjacent tetrahedra. This structure forms a large crystal cavity that can be occupied by cations and water molecules. These cations and water molecules have greater mobility, allowing for cation exchange and reversible dehydration. 4A molecular sieve conducts ion exchange with aluminum ions on the framework, and each aluminum ion has a negative charge, which can bind not only sodium ions, but also other cations. Calcium and magnesium ions can enter the large crystal pores occupied by the original sodium ions and replace the sodium ions in the 4A molecular sieve, that is, the sodium ions in the 4A molecular sieve can undergo ion exchange and can be combined with Ca2 and Mg2 ions in hard water. The exchange achieves the purpose of softening the water quality.

 

Molecular Formula Na2O·Al2O3·2SiO2·9/2H2O
SiO2/ Al2O3 ≈ 2
Normal Pore Opening 4 Angstroms (Å)
Regeneration temp. (°C) 200-315
Advantages High Stability; High Strength; Large Water Absorption; Low Attrition; Deep Dehydration
