Rely on its own unique void structure.

The pore size of zeolite is uniform, the internal void structure is developed, the specific surface area is large, the adsorption capacity is strong, and contains a large number of invisible pore sizes. The pore size in 1g zeolite material can be expanded to the specific surface area of 500-1000m2, which is higher for special purposes.

Adsorption between molecules

It is also called "Vandewar Gravity". Although molecular motion speed is affected by temperature, material and other reasons, it always keeps moving in the micro environment. Due to the mutual attraction force between molecules, when a molecule is trapped in the inner pore volume of zeolite, it will lead to more molecules being absorbed until the adsorption of zeolite is saturated.

physical adsorption

It mainly occurs in the process of removing impurities in the liquid phase and gas phase. The porous structure of zeolite provides a large amount of specific surface area, which makes it very easy to absorb and collect impurities. Due to the interaction of molecules, a large number of molecules on the pore wall of zeolite can generate strong gravity, just like magnetic force, So as to achieve the purpose of attracting impurities in the medium to the aperture.

adsorbent

In addition to physical adsorption, chemical reaction also often occurs on the surface of zeolite, which contains a small amount of chemical combination, oxygen and hydrogen in the form of functional groups. These surfaces contain oxides or complexes that can react with the adsorbed substances, so that they can combine with the adsorbed substances and aggregate to the interior and surface of zeolite.
