High Purity 13X Molecular Sieve Desiccant As Dryer Agent Gas Deep Drying
13X Molecular Sieve Desiccant Introduction
Molecular sieve has a uniform microporous structure, this pore with uniform size,molecule is smaller than the diameter of the molecules can be adsorbed into the cavity of the internal by these pore,and have a preferential adsorption capacity for polar molecules and unsaturated molecules,So the different degree of polarity, different degrees of saturation, different molecular size and different boiling points of the molecules can be separated, that is, with the "sieving" the role of molecules, so called molecular sieve.
A main component of X-type molecular sieve is aluminosilicate, silicon-oxy and alumina tetrahedron to form a FAU-type structure the main crystal structure is twelve membered rings.
In molecular sieve 13X, sodium ion formation with a pore opening of 9-10Å (1Å=1×10-10m), that is type 13X (also known as NaX-type) molecular sieve.
