Zeolite molecular sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal holes have the function of adsorbing molecules.
There are pores connected to each other, and molecules pass through the pores channels.
Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform.
Molecular sieves selectively adsorb molecules according to the size of the holes in their crystal,that is, they adsorb molecules of a certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
4A molecular sieve is one of the most consumable molecular sieves used in the industry, its selective adsorption to water is higher than any other molecule. Chemequip 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters not more than 4Å. It's usually used for gas and liquid drying but also for refining and purification of certain gases or liquids such as the production of argon. 4A Molecular Sieve Application Fields
1) Deep drying of gases and liquids, such as air, natural gas, hydrocarbons and refrigerants
2) Production and purification of argon
3) Static drying of electronic components and substances susceptible to moisture deterioration
4) Dehydrating agent in paints, polyesters, dyes and coatings
5) Detergent additives
6) Sewage treatment
7) Water treatment - hard water softener
8) Metallurgical industry - separating agents
