Molecular Sieve 4A
Performance:
4A molecular sieve pore size is 4A, can absorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, can't absorb molecular sieve that diameter greater than 4A(including propane), the water selecting adsorption performance is higher than other molecules. 4A is the largest one of the molecular sieve varieties of industrial usage.
Use:
Molecular sieve mainly used for air, gas, alkanes, the depth of the refrigerant gas and liquid dry; Argon gas making and purification, pharmaceutical packaging, electronic components and mutable material static dry; Paint, coating, fuel as dehydrating agent.
