Molecular sieve manufacturer explains the performance of molecular sieves
I believe all readers here must have a basic understanding of what molecular sieves are, but do you know what are the characteristics of zeolite molecular sieves? Zeolite molecular sieves have three main characteristics, the first is adsorption performance, the second is ion exchange performance, and finally One is the substance in the middle. Today, the editor of
molecular sieve manufacturer uses this article to introduce the performance of molecular sieves one by one, and help everyone to understand more about molecular sieves.
Let me first talk about the adsorption capacity of molecular sieve. Adsorption is a process of physical change and will not have any effect on the internal structure of molecular sieve. The existence of adsorption force makes it possible to form adsorption force on the solid surface. When the fluid passes through the molecular sieve, some molecules in the fluid collide due to irregular motion and hit the surface of the adsorbent, thereby agglomeration occurs, and the number of molecules in the fluid is greatly increased. Therefore, as long as the manufacturer finds a way to remove the adsorbed molecules concentrated on the molecular surface, the molecular sieve will restore its adsorption capacity. The molecular sieve has extremely strong polarity and can exert a strong effect on molecules with polar groups. It produces strong adsorption capacity for polarized molecules through induction.
Generally speaking, ion exchange often refers to the cations outside the framework of the zeolite molecular sieve, and the cations of the molecular sieve exchange quickly with other substances. The compensation ions outside the framework of the zeolite molecular sieve are generally composed of alkali metals or alkaline earth metals. They can easily cross form metal ions of different valences in the metal salt aqueous solution. After the exchange, the number, position and size of the oxygen ions inside the molecular sieve will be very large. The change in pores will cause vacancies in a certain position, resulting in a larger inner diameter of the structure, or relatively small ions after exchange, the pores will be blocked, thereby making the effective molecular structure smaller.
Since the surface of most zeolite molecular sieves contains strong acid, a strong Coulomb effect will be formed in the crystal, making it have superior performance. The above are the three characteristics of molecular sieve introduced to you today. I hope to help you have a deeper understanding of its properties. Those who are interested can verify it through related experiments and have a deeper understanding of molecular sieves.
