I. Product Introduction
Our company's 5A molecular sieve is a calcium-potassium type aluminosilicate with a crystal pore size of 5Å (0.5nm), which can adsorb molecules with a critical diameter no larger than its pore size.
II. Main Applications
Dehydration, decarbonation, decarbonylation, and desulfurization of natural gas; drying and purification of air, nitrogen, and inert gases in industry, drying and purification of hydrogen; separation of isomeric hydrocarbons, enrichment of oxygen, etc.; widely used in oxygen production industry to adsorb moisture, carbon dioxide and some organic gases.
III. Storage Conditions
Dry, cool, and dark.
IV. Implementation Standards
Implemented according to the superior product indicators of industry standard GB/T 13550-2015.

Note: 1) For molecular sieves with a particle size of d(1.5mm～1.7mm), the mass fraction of samples with a bar length of 1mm～6mm accounts for the total mass;
For molecular sieves with a particle size of d(3.0mm～3.3mm), the mass fraction of samples with a bar length of 3mm～9mm accounts for the total mass;
The packaging water content is based on the factory inspection.
