Adsorption: Molecular sieve has a strong adsorption capacity and is able to adsorb specific molecules in gases or liquids. Its adsorption effect is mainly based on molecular gravity, that is, the "surface force" generated by solid surfaces.

Selectivity: Because the pore size of the molecular sieve is uniform, molecules can enter the pore and be adsorbed only when the molecular dynamics diameter is smaller than the pore size of the molecular sieve. Therefore, molecular sieves can be sieved according to the size of the molecule.

High temperature resistance: Molecular sieve has good thermal stability and can maintain its structure and performance at high temperatures.

Ion exchangeability: Compensated cations outside the molecular sieve framework can be exchanged under certain conditions, thereby changing the pore size and performance of the molecular sieve.

Catalytic properties: Molecular sieve has a unique regular crystal structure, a strong acid center on the surface, and a powerful Coulomb field in the crystal pores to polarize, so it is often used as a catalyst or catalyst support.
