Zeolite Introduction

zeolite molecular sieve is a cubic lattice of an aluminosilicate compound having. Molecular sieve has a uniform porous structure, the diameter of its pores of uniform size, these cavities can adsorb molecules smaller diameter than the internal bore, and an unsaturated polar molecules and molecules having a preferential adsorption capacity, and thus able to very different degree, different degree of saturation, and boiling points of different molecular sizes of different molecules separated, that has the effect of "screening" elements, so called molecular sieves. Since the molecular sieve dryer have a high adsorption capacity, high thermal stability other adsorbents that are not so widely applied molecular sieve.
In the field of biological macromolecules, a common bio-rad SEC sieve prepacked columns.
US scientists have found that by adjusting the temperature, to precisely control one titanium silicate material pore size, to create a sophisticated molecular sieve. Some internal crystal material has a large number of uniform pore size smaller than the molecules can pass through the holes, while large molecules can not pass through, and thus serves to separate different 4a molecular sieves , such materials are known as molecular sieve.

the "molecular sieve powder" refers to the zeolite

In general, the "molecular sieve powder" refers to the zeolite synthesis After washing, the product after drying (sodium or potassium type, etc.), no activity; also some of the active zeolite component of the catalyst before forming a "molecular sieve powder ", is hydrogen, synthetic zeolite powder suppliers  there is the activity. Now zeolite powder original sub 3A4A5A and other industrial raw powder, and clay bowls direct participation after drying, burning can be made ​​of the appropriate molecular  zeolite molecular sieve sieve. General granular zeolite molecular sieve is made ​​from raw powder and binder forming system, molecular  activated molecular sieve zeolite powder is true, there is no relationship with the activity. A water content of 40% is called the original powder, dried to 20% moisture content, also known as raw powder. Strictly speaking, the moisture content of 2% or less of the original powder is activated powder.
