Molecular Sieve 3A/5A/13X/13X-APG/13X-HP/Li-X/CMS
Molecular Sieve are so named because there are uniform pores inside the particles of molecular sieves, which can separate molecules of different sizes according to the size of the pores.
Zhongci, as a professional production factory for more than 20 years, produces many types of zeolite molecular sieve adsorbents. Some of the more common molecular sieve types include Molecular Sieve 3A, Molecular Sieve 4A, Molecular Sieve 5A, Molecular Sieve 13X, Molecular Sieve 13X-APG, Molecular Sieve 13X-HP, Molecular Sieve Li-X, Carbon Molecular Sieve, Nay Molecular Sieve, XH-7/9 Molecular Sieve etc.

Molecular sieve is a kind of synthetic silicoaluminate with microporous cubic lattice.depending on the size of the pores inside the crystal,the molecules of different substances are adsorbed or repelled,and are therefore called "molecular sieve".substances whose molecular diameter is smaller than the pore diameter of the molecular sieve crystal can enter the molecular sieve crystal and be adsorbed.
5A-Pressure swing adsorption. Air cleaning dehydration and carbon dioxide.
4A-air, gas, alkanes, refrigerant gas and liquid depth and dry. Argon gas making and purification.
pharmaceutical packaging, electronic components and metamorphic material static and dry.
paint, fuel, as dehydrating agent in the coating.
3A- all kinds of liquid (such as ethanol) dry
2, air dry
3, refrigerant drying
4, natural gas, methane gas is dry
5, unsaturated hydrocarbon and cracking gas, ethylene, acetylene, propylene, butadiene, dry.
Note: Molecular sieve before use shall prevent the adsorption of water, gas or liquid, organic otherwise, shall be renewable.
Summary
Molecular sieve is a kind of cubic crystal aluminosilicate compounds. Molecular sieve has the advantages of uniform porous structure, the diameter of the aperture size uniform, these holes to the adsorption of molecules smaller than the diameter of the cavity to the internal, and the polar molecules and unsaturated molecules has a preferential adsorption capacity, and are better able to different degrees, different saturation degree, molecular size and the boiling point of different molecules are separated, that is "screening" molecular, the so-called molecular sieve. Molecular sieve has the advantages of high adsorption capacity, high thermal stability, and so on, so that the molecular sieve is widely used.
