Molecular Sieve Desiccant Bag

There is a kind of natural aluminosilicate in nature, which has the functions of sieving molecules, adsorption, ion exchange and catalysis. This natural substance is called zeolite, and synthetic zeolite is also called molecular sieve.

PRODUCT INTRODUCTION

A synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules. Its general chemical formula is (M'2M)O·Al2O3·xSiO2·yH2O, and M'and M are respectively monovalent and divalent cations such as K+, Na+ and Ca2+, Ba2+, etc. It has many pores with uniform pore size and neatly arranged pores in its structure. Molecular sieves with different pore sizes separate molecules of different sizes and shapes. According to the different molecular ratios of SiO2 and Al2O3, molecular sieves with different pore sizes can be obtained. Its models are: 3A (potassium A type), 4A (sodium A type), 5A (calcium A type), 10Z (calcium Z type), 13Z (sodium Z type), Y (sodium Y type), sodium mordenite type Wait.

CHARACTERISTIC

Absorption Function

 

The adsorption of zeolite molecular sieve is a physical change process. The main reason for the adsorption is a kind of "surface force" produced by molecular gravity acting on the solid surface. When the fluid flows through, some molecules in the fluid collide with the surface of the adsorbent due to irregular motion, causing molecular concentration on the surface. Reduce the number of such molecules in the fluid to achieve the purpose of separation and removal.

Since the adsorption does not undergo chemical changes, as long as we try to drive away the molecules concentrated on the surface, the zeolite molecular sieve has adsorption capacity again. This process is the reverse process of adsorption, called analysis or regeneration.


Since the zeolite molecular sieve has a uniform pore size, only when the molecular dynamics diameter is smaller than the zeolite molecular sieve can it easily enter the crystal cavity and be adsorbed. Therefore, the zeolite molecular sieve is like a sieve for gas and liquid molecules, and it is determined whether to be adsorbed or not according to the size of the molecule. .
Since the zeolite molecular sieve has strong polarity in the crystalline cavity, it can have a strong effect on the surface of the zeolite molecular sieve with molecules containing polar groups, or by inducing the polarization of the polarizable molecules to produce strong adsorption.

This kind of polar or easily polarized molecule is easily adsorbed by polar zeolite molecular sieve, which reflects another kind of adsorption selectivity of zeolite molecular sieve.
