What Is The Difference Between Molecular Sieves And Desiccants?

- Mar 29, 2019-

It is well known that both molecular sieves and desiccants have the function of dry adsorption. What is the difference between these two products?


Molecular sieve: A natural or synthetic chemical with a network structure. Molecular sieves are crystalline silicates or aluminosilicates which are connected by a silicon oxytetrahedron or an aluminoxy tetrahedron through an oxygen bridge to form a pore size and cavity system of molecular size (usually 0.3 to 2.0 nm). It has the characteristics of sieving molecules.


Desiccant: Desiccant is also called sucking agent. It is used for moisture-proof and mildew-proof. It acts as a drying agent. It is a physical adsorption desiccant and a chemical adsorption desiccant according to different adsorption methods and reaction products.


Molecular sieve desiccant: A desiccant product that is artificially synthesized and has strong adsorption to water molecules. The pore size of the molecular sieve is controlled by the difference in processing technology. In addition to adsorbing water vapor, it can also adsorb other gases. At high temperatures above 230 ° C, water molecules are well accommodated.


Regarding the difference between molecular sieves and desiccants, a detailed explanation has been given in the text. In the future use, everyone must first understand the knowledge of the products in order to make better use of the products!
