Molecular Sieve

Molecular Sieve 4A 1)Good drying 2)Used for gas

Molecular Sieve 4A

Brief  Instruction

E04—DG molecular sieve’s aperture is 4A,it can adsorb the molecule that critical diameter is less than 4A,like water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide,ethylene, propylene and so on,and the selective adsorption performance to water is higher than any other molecules.

Usage

E04—DG molecular sieve’s aperture is a kind of molecular that used most in industry.it is mainly used to depth dry liquid and gas (like air,natural gas, alkane, refrigerants and so on); produce and purify argon; Static dry drug packaging, electronic component and easy metamorphic material.

Regeneration

E04—DG molecular sieve can blow or evacuate on condition of increasing the temperature,then it can regenerate and reuse.The degree of regeneration depends on the temperature and humidity of sweep gas.

Matters needing attention

E04—DG molecular sieve is easy to absorb moisture,so please do not open the seal steel barrel before use,and it should store in the environment with dry and ventilated.Before use,please avoid it to adsorb water, organic gas or other liquid,or make it regeneratied,then make use of it.
