4A molecular sieve is one of the most consumable molecular sieves used in the industry, its selective adsorption to water is higher than any other molecule. Howay 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters not more than 4Å. It’s usually used for gas and liquid drying but also for refining and purification of certain gases or liquids such as the production of argon.
Application
Deep drying of gases and liquids, such as air, natural gas, hydrocarbons and refrigerantsProduction and purification of argon
Static drying of electronic components and substances susceptible to moisture deterioration
Dehydrating agent in paints, polyesters, dyes and coatings
Detergent additives
Sewage treatment
Water treatment - hard water softener
