Product Description of 4A Molecular Sieve Desiccant

4A molecular sieve is an alkali metal aluminosilicate, the chemical formula is Na2O.AI2O3.2SiO2.9/2H2O, and the pore size is 4A. It can absorb water, NH3, H2S, sulfur dioxide, carbon dioxide, C2H5OH, C2H6, C2H4 and other critical diameters not greater than The molecule of 4A does not adsorb Tianke molecules (including propane) with a diameter larger than 4A. The selective adsorption performance of water is higher than that of any other molecules. It is one of the largest molecular sieve varieties used in industry and is widely used in the drying of gas and liquid. , and can also be used for the purification and purification of certain gases or liquids, such as the preparation of nitrogen.

 

Ion transfer properties, water softening function
Each oxygen atom in the framework of the 4A molecular sieve is shared by two adjacent tetrahedra. This structure creates a large crystal cavity that can be occupied by cations and water molecules. These cations and water molecules have greater mobility allowing 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 the Ca2 and Mg2 ions in hard water. Exchange to achieve the purpose of softening water quality.
4A molecular sieve binds calcium and magnesium ions slower than sodium tripolyphosphate, and its binding ability with magnesium ions is weak. 4A molecular sieve can easily remove a small amount of harmful heavy metal ions (such as Pb2, Cd2, Hg2) from the aqueous solution, which is of great significance to purify water.
