Zeolite
molecular sieves have the structure and characteristics of crystals, the
surface is a solid skeleton, and the internal holes have the function of
adsorbing molecules. The pores are interconnected, allowing molecules to pass
through. Due to the uniform pore size distribution, molecular sieves can
selectively adsorb molecules based on their size, which is why they are called
"molecular sieves."
The function of molecular sieve adsorption or repulsion is affected by the polarity of the molecule. Synthetic zeolite has the special function of selective adsorption according to the size and polarity of the molecule so that gases or liquids can be dried or purified, which is the basis for the separation of molecular sieves. Synthetic zeolite can meet the extensive needs of the industry for adsorption and selection of specific products, and it is also widely used in industrial separation.
