Molecular sieve is a kind of aluminosilicate, which is mainly composed of silica alumina through the oxygen bridge to form an open skeleton structure. In this structure, there are many pores with uniform pore size  well arranged pores, which have large internal surface area. In addition, it also includes the combination state of metal ions  water with low electricity price  large ion radius. Due to the continuous loss of water molecules after heating, but the crystal skeleton structure remains unchanged, so many holes of the same size are formed,  these holes are connected by a number of micropores with the same diameter,  the molecules of the material have the same size. Diameter. Holes smaller than the diameter of the hole are absorbed into the cavity. Molecules larger than the pores are repulsed, so molecules of different sizes are separated until sieving is called molecular sieves. It is mainly used for deep drying of various gases  liquids, separation  purification of gas, liquid  catalyst carrier. Therefore, it is widely used in refining, petrochemical, chemical industry, metallurgy, electronics, national defense industry  so on. Agriculture, environmental protection  many other aspects are also increasingly used.

3A molecular sieve is mainly used for drying insulating glass of petroleum cracking gas, olefin, refinery, oilfield gas, chemical industry, pharmaceutical industry, industrial desiccant, etc.
