What is molecular sieve?
Molecular sieve is a kind of aluminosilicate compound with cubic lattice. It mainly consists of aluminosilicate connected by oxygen bridge to form an empty skeleton structure. In the structure, there are many uniform pore channels and well-arranged holes with large inner surface area. In addition, it contains metal ions with lower electricity price and larger radius of ions and hydrated water. Because the water molecule loses continuously after heating, but the crystal skeleton structure remains unchanged, many cavities of the same size are formed, and the cavities are connected by many micro-holes of the same diameter. These micro-holes are uniform in diameter and can absorb molecules smaller than the diameter of the channel into the inside of the hole, while larger molecules than the channel. Because of exclusion, molecules with different shapes and diameters, polarity, boiling point and saturation can be separated, which is called molecular sieve.
The role of molecular sieves:
At present, molecular sieves are widely used in chemical, electronic, petrochemical, other industries.
Molecular sieve models commonly used in gas industry:
Type A: potassium A (3A), sodium A (4A), calcium A (5A)
Type X: Calcium X (10X), Sodium X (13X)
Type Y: Sodium Y, Calcium Y
Molecular sieves have strong hygroscopicity and should be used for purification of gases. When preserved, direct exposure to air should be avoided. Molecular sieves with long storage time and moisture absorption should be regenerated before use. Molecular sieves avoid oil and liquid water. Avoid contact with oil and liquid water when using. In industrial production, the drying gases are air, hydrogen, oxygen, nitrogen and so on. Two adsorption dryers are connected in parallel, one working, and the other can be regenerated. Alternate work and regeneration to ensure continuous operation of equipment. The dryer works at room temperature and regenerates by flushing air at 350 C.
Can molecular sieves be cleaned?
Molecular sieve is a reusable aluminosilicate compound, which is very vulnerable to acid and alkali damage. It is generally not recommended to clean it. If water-soluble substances can be washed with clean water, then dried in a drying box at 150 degrees for one hour, then roasted in a high temperature muffle furnace at 500-550 degrees for one hour, the crystalline water can be removed and regenerated. That's it.
3A Molecular sieve
The hollow glass molecular sieve can simultaneously absorb the water and
residual organic matter in the hollow glass,so that the water and residual
organic matter in the hollow glass can be kept clean and transparent even at very low temperature,and at the same time,it can fully reduce the strong internal and external pressure difference of the hollow glass due to the great changes of
season and day night temperature difference,Hollow glass molecular sieve also solves the problem of distortion and fragmentation caused by expansion or
contraction of insulating glass,and prolongs the service life of insulating glass.
