Molecular sieve (also called synthetic zeolite) is a kind of microporous aluminosilicate crystal. Its basic skeleton structure consists of silicon oxide, aluminum oxide tetrahedral. There are metal cation in its crystal lattice (such as Na +, K +, Ca2 +, Li +, etc.), these cation can balance the excess negative charge. According to their type of zeolite crystal structure is divided into A type, X type, Y type. According to molecular sieve aperture size, there are 3A, 4A, 5A, 10X, 13X. 4A molecular sieve is Na-A molecular sieve, aperture 0.4nm; if Na replaced by K, aperture 0.3nm, is 3A molecular sieve; if over 1/3 Na replaced by Ca2+, aperture 0.5nm, is 5A molecular sieve.
Molecular sieve adsorption capacity come from physical adsorption (Van der Waals forces), its cavities have a strong polarity and coulomb field which show a strong adsorption capacity to polar molecules (such as water) and unsaturated molecules. Molecular sieve has a uniform pore structure, which can separate different polarity, different saturation, different sizes and different boiling molecules. It has the effect of "sieving", so called molecular sieves.
Yuanying molecular sieve has quick adsorption speed, excellent adsorption performance, high crushing resistance, strong pollution resistance, large specific surface areas, big pore volume, more regenerative times, strong thermal stability, very long life***n.
There are the following types of products: 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, 13X molecular sieves, insulating glass desiccant, refrigerant desiccant XH-5, XH-7, XH-9, XH-11, clay desiccant, container desiccant, carbon molecular sieves.
