Spherical 3-5 mm 4A molecular sieve

Subsieve
Molecular sieve mainly adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene. It does not adsorb any molecules with a diameter larger than that, including propane, and its selective adsorption performance for water is higher than any other molecules. It is one of the most widely used molecular sieves in industry.

Regeneration
Moisture removal depends on the pressure, temperature and moisture content of the regeneration gas. . Generally, the dry gas passes through the molecular sieve bed under pressure for an hour, so that the outlet temperature reaches ℃ and is cooled.
Removing organic matter replaces organic matter with water vapor, and then removes the water.
Storage
Store at room temperature, the relative humidity should not be greater than 100%, and should not be directly exposed to the air to avoid water acid and alkali.
Precautions Do not open the package before use to avoid moisture and affect the adsorption effect.
