Introduction

 

Molecular Sieve type 4A (Angstrom) is an alkali alumino silicate, obtained through synthesis of type A zeolite in sodic form. 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). Galaxychem type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

Typical Application

 

Deep drying of air, Natural gas, alkane and refrigerant.
Generation and purification of argon.
Static dehydration of electronic element, pharmaceutical and unstable materials.
Desiccant for paint, dope and foul etc.
Type 4A molecular sieve is typically used in regenerable drying systems to remove water vapor or contaminants which have a smaller critical diameter than four angstroms.

 

Attention:

 

1. The product cannot be exposed in the open air and should be stored in dry condition with air-proof package.
2. The product should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.

 

Packaging:

 

1, 25KG/carton; 2, 35KG/carton drum; 3, 150KG/Sealed iron drum

 

Delivery Time:

 

About 3-15 days after the payment.
