Molecular sieve

Molecular Sieve High Voltage is a kind of cubic lattice Silicon aluminate compounds, mainly composed of silica-alumina by oxygen bridges to connect empty skeletal structure, there are many uniform pore size in the structure of pores and neat, and a large internal surface area of the cavity.Also contains the price lower and larger Ionic radius of metal ions and combined state of the water.Due to water molecular in heating Hou continuous to lost, but Crystal skeleton structure not variable, formed has many size same of empty cavity, empty cavity and has many diameter same of micro-hole connected, these tiny of cavities diameter size uniform,activating molecular sieves can put than channel diameter small of molecular adsorption to cavities of internal in the to, and put than channel big have molecular exclusion out, thus can put shape diameter size different of molecular, polar degree different of molecular, boiling point different of molecular, saturated degree different of molecular separation from, that has "screening" molecular of role, Known as molecular sieves.Current molecular sieve in chemical, electronics, petrochemicals, natural gas is widely used in the industry.
