Applications of XINTAO Molecular Sieve 4A
2019-06-28 16:31:25   

Molecular Sieve type 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). XINTAO type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger。 Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons。 Branched chain hydrocarbons and aromatics are excluded。

4A molecular sieve is considered as one of the best desiccant for a variety of applications that includes:

· Dehydration of drugs, electric components and unpreserved chemicals when packed

· Removal of moisture in plastics and paints

· Drying of Natural gas, petroleum gas and cracked gas

· Dehydration of methanol and ethanol

· Generation and purification of argon

· Drying of air filled or gas-filled insulating glass units

· Dehydration of unsaturated hydrocarbons

· Drying and purifying of Ammonia gas
