3A molecular sieve powder is a finely processed desiccant material designed for precise moisture control in industrial applications. Featuring a uniform microporous structure, it selectively adsorbs water molecules while preventing the uptake of larger molecules, ensuring superior drying performance and chemical stability. This material is widely used in coatings, adhesives, insulating glass production, and fine chemical synthesis, delivering reliable moisture adsorption for continuous industrial processing.
Product Overview
3A molecular sieve powder is a synthetic white powder primarily composed of aluminosilicates. It has excellent shape-selective adsorption, catalytic, and ion exchange properties. The product undergoes high-temperature calcination and can be formed into spherical, rod-shaped, or irregularly shaped molecular sieves. It can also be used directly as activated powder. With a pore size of approximately 3Å, 3A molecular sieve powder is widely used in gas and liquid separation, drying, and catalytic reactions.
Key Features
- Excellent Adsorption Performance: 3A molecular sieve selectively adsorbs small molecules such as water, ammonia, ethylene, etc., making it ideal for a variety of molecular separation and drying processes.
- Catalytic and Ion Exchange Properties: In addition to adsorption, it is also used in catalytic reactions and ion exchange processes, improving reaction efficiency.
- High Purity: The fine synthesis process ensures high purity and stability, making it suitable for demanding industrial applications.
- Customizable Particle Size: Particle size can be adjusted according to specific application needs, offering flexible application choices.
- Easy Processing: Can be processed into various forms by adding binders and other materials, adaptable to different industrial needs.
Applications
- Gas Drying and Separation: Used for drying and separating gases such as air and natural gas, particularly in removing moisture from gases.
- Liquid Drying: Widely used in liquid separation and dehydration processes, especially in oil and gas and solvent purification industries.
- Catalytic Reactions: As a catalyst support, it is used in petroleum refining, catalytic cracking, and other catalytic processes.
- Ion Exchange: Applied in water treatment, mineral processing, and petrochemical industries for ion exchange to remove harmful ions.
- Molecular Sieve Synthesis: Used as a raw material for synthesizing other molecular sieves or as a powder material required in molecular sieve synthesis processes.
