Product description
Parameters
   Molecular sieve is a potassium-sodium aluminosilicate, also known as 3A zeolite molecular sieve. The pore size of the crystal is 3 angstroms. (Ie 0.3 nm) is mainly used to adsorb water and all molecules with a molecular dynamic diameter less than 3 angstroms, and does not adsorb any molecules with a diameter greater than 3 angstroms.
   Our company's 3A molecular sieve product has the characteristics of fast adsorption speed, many regeneration times, good compressive strength and anti-pollution ability, etc. It is an excellent desiccant for gas and liquid phase deep drying in related industries.

Remarks:
The technical indicators and particle specifications of molecular sieve can be customized according to the actual production of customers.
 
Application areas:
★Drying of petroleum cracked gas and unsaturated hydrocarbon materials (such as ethylene, propylene, butadiene, etc.)
★Drying of benzene, toluene, xylene and other solvents (such as methanol, ethanol).
★The dehydration of natural gas prevents the formation of carbonyl sulfide.
★Chemical, refrigeration, electronics and other industries remove raw materials, reactants, special systems, and small amounts of moisture in a closed environment to prevent side reactions and improve the quality of products; protect special systems to prevent the generation of harmful substances; keep the closed environment dry to prevent high precision The product is damaged due to moisture absorption.
 
Precautions:
1. This product is easy to absorb moisture and should not be directly exposed to the air. It should be stored in a dry and ventilated place. After a period of time, it needs to be regenerated to reach adsorption saturation. The outlet temperature during regeneration should not be lower than 280°C.
2. The product is used in different fields, and the technical index requirements are different, and the purpose should be informed when ordering.
