the Performance of zeolite 3a molecular sieve

Yu and zeolite 3a molecular sieve  metallic luster, hardness of 3~5, relative density is 2~2.8, colored with natural zeolite, synthetic zeolite is white, insoluble in water, thermal stability and resistance to acid increasing with the improved SiO2/Al2O3 ratio.mole sieve dehydration have very large surface areas, 300~1000m2/g, Crystal surface in highly polarized, is a kind of high efficiency adsorbent, also a solid, the surface has a high acid concentration and intensity, can cause the carbenium ion-catalyzed reactions.When the composition of the metal ion exchange with other ions in solution, you can adjust the aperture, change its adsorption and catalytic properties, which produce different molecular sieve catalysts.

Molecular sieve

Due to contains electric price lower and ion RADIUS larger of metal ion and combined state of water, water molecular in heating Hou continuous to lost, but Crystal skeleton structure not variable, formed has many size same of empty cavity, double glazing molecular sieve empty cavity and has many diameter same of micro-hole connected, these tiny of cavities diameter size uniform, can put than channel diameter small of molecular adsorption to cavities of internal in the to, and put than channel big of molecular exclusion out, thus can put shape diameter size different of molecular, polar degree different of molecular, boiling point different of molecular, Saturation level separating different zeolite 3a molecular sieve  that is, with "screening" molecular function, it is called molecular sieve.Current molecular sieves in the metallurgical, chemical, electronics, petrochemicals, natural gas is widely used in the industry.
